January 2021 Virtual Meeting

The Reaction Research Society’s first meeting of 2021 took place this past Friday, January 8th and was attended by 11 members. Dave Nordling provided a review of the December 2020 event at the MTA, a written account of which can be seen in the post preceding this one.

PLANS FOR THE UPCOMING MTA EVENT

The first discussion was regarding plans for the upcoming MTA event on Saturday, January 9th. Dimitri (and family), Wolfram, Bill, Waldo, and Dave (as Pyro Op) stated their intentions to attend the launch. Plans include continuing repair and replacement of the bent panel on the vertical launch structure led by Dimitri and Waldo, a launch of Dave’s hybrid rocket, a demonstration flight of Wolfram’s Gas Guzzler, and mention of a grill-out with hamburgers! Expect a launch event update on the results soon.

RESTROOM AND OTHER FACILITIES IMPROVEMENTS

The discussion continues on improving the restroom facilities at the MTA. While the Executive Committee pursues bids from contractors and other options for a more substantial restroom facility, finding a more immediate replacement for the current pit toilet is a top priority. Digging a new pit toilet should be made much easier by the recent delivery of a CAT backhoe to the Mojave. Due to security concerns, the equipment is being stored at the FAR site in view of their security cameras. Larry and Keith agreed to look into options for cameras that could provide similar security at the MTA.

While the initial plan was to drag the concrete plinth from the current pit toilet to the new one, a decision was made to proceed with building a new wooden platform to mount the port-a-john instead. Of concern was the seemingly likely outcome of damage to the concrete plinth when trying to place it with the equipment available. Dimitri outlined his idea for the new structure and offered to sketch out a more formal design after reviewing at the MTA at the launch event.

DUES REMINDER AND FUNDRAISING BRAINSTORM

The RRS treasurer offered a reminder for members to pay their dues for 2021, which remain at $40 for full membership and $30 for student membership. As a reminder, the full membership dues will be increasing to $50 in 2022. For questions regarding dues payments, contact the RRS treasurer:

treasurer@rrs.org

Most of the members on the call got involved in the brainstorming session on how to increase fundraising at the society to cover our insurance and other yearly costs. Xavier proposed putting on a holiday party for the society as a ticketed event, and offered to take charge of scoping out costs and possibilities for the 2021-2022 winter season (when in-person gatherings will hopefully be allowed again). Dimitri discussed the challenges and opportunities involved in listing the MTA site with the Kern County Film Commission as a shoot location. The possibility of holding an auction, either stand-alone or as a part of the yearly symposium was also proposed, and Dimitri offered to put together a draft form letter to submit to companies to solicit donations. Additional items would be donated by members or other involved entities.

2020 CONSTITUTIONAL COMMITTEE

A request was made for an update on the status of the 2020 Constitutional Committee, which has been drafting changes to the constitution of the Reaction Research Society. Committee member Frank described that only a few outstanding issues remain, including the definition of active membership, which need to be finalized by the Executive Council before being presented and voted on. The Executive Council intends to meet on this issue soon and present the new constitution to the voting membership in the coming months.

December 2019 meeting

Dave Nordling, Secretary, Reaction Research Society


The Reaction Research Society (RRS) met for our last monthly meeting of the year on December 13, 2019, at the Ken Nakaoka Community Center in Gardena, California. We had a full house with three different universities represented and a few returning members who came out to see how this year was ending for the society. The Compton College STEM club came out and some of them joined the RRS that night. Compton College is working on their own liquid rocket build which may next year see some important testing conducted.

Frank Chandler who is the director of Cal Poly Pomona’s (CPP) liquid rocket group and an RRS member was also at the meeting to discuss a March test date at the RRS MTA. He mentioned that Cal Poly Pomona recently had a tour of the AstroPak company in Downey, California. AstroPak has been in the business of cleaning mechanical parts for oxygen service for many years. The CPP students got to see each step of the process and learned the importance of maintaining this cleanliness throughout operations. Nearly all liquid rocket projects have decided to use liquid oxygen which has it’s own challenges to meet. Studying and keeping good cleanliness practices is paramount to avoiding catastrophe.

Chris Lujan and Frank Miuccio establish the link to bring in Richard Garcia, our director of research into the meeting.

We also were happy to have our director of research, Richard Garcia, calling into the meeting. Frank Miuccio and Chris Lujan have been very helpful in establishing a call-in number for some of our former and current members to call in when they are away from the city. We hope to have more of our membership calling in so that they may remain informed and active with their membership in the society. As per our tradition, we always value those making the trip to visit us in person.

After calling the meeting to order, and the reading of the treasury report, we covered our agenda items. We covered nearly all of our agenda and had time for special presentation from two members of Long Beach Rocketry at California State University Long Beach (CSULB). The purpose of their visit was to introduce themselves to the RRS.

Corey Fraga and Dan Dao gave us a short presentation of their team and some of their recent accomplishments. Their solid motor rocket project started in 2015 and has done well in recent competitions including the NASA University Student Launch Initiative (USLI) taking fifth place among a long list of worthy competitors. They also brought their most recent prototype vehicle which has a quadricopter drone built into the cargo bay. After the rocket completes its flight and gently touches down from its parachute recovery system, the cargo bay opens from an electric motor driven mechanism which allows the drone to take off and survey the landing site. The idea is to create a system that could be useful in planetary exploration or even in remote or dangerous areas here on Earth.

CSU Long Beach (Corey Fraga, Dan Dao) makes their presentation on their latest competition at Huntsville, AL.

The Long Beach Rocketry group offered to give the RRS a tour of their lab facilities on campus. The RRS graciously accepted their invitation. We should hopefully announce a date soon for this event.

[1] Results from the last MTA launch

The launch report from the December 7, 2019, event has already been posted. We had a successful event despite an earlier concern for bad weather. Thankfully, the rain fell early and had cleared by Saturday morning. We were able to get our equipment set up for the event, but the society needs to invest in a simple sumping pump in case we need to remove any standing water from our bunkers or other enclosed spaces that have failed to drain from a recent rain or flooding. We are thankful to our neighbors at the Friends of Amateur Rocketry (FAR) for letting us borrow their sump pump.

Two students of 99th Street Elementary wait for the next launch in the RRS MTA observation bunker. Many of our observers could use something to stand a little higher to see better.

I also noticed that we could use a few more cinder blocks in the blockhouse. Many of our students are too short to see over the wall and the few blocks we already have are not enough. The RRS should buy a few more cinder blocks and possibly make some standing benches to help our students see their hard work better from the safety of the observation bunker.

An RRS standard alpha takes off into the moist air of December at the MTA.

Another observation made was the students from the neighboring Friends of Amateur Rocketry (FAR) site were often seen walking around too close to the RRS launching site as we were conducting road and air checks for our alpha rocket launches. It appeared that they were searching to recover their rocket from their prior flight, but we aborted three different countdowns due to car movements seen, or people crossing by on the north road adjacent to our property, and even one oblivious individual who was walking downrange of our own RRS MTA launch site as we were in the count!. The RRS and FAR must better coordinate our launch and recovery protocols respecting each others’ boundaries if only for the safety of all people concerned.

FAR and the RRS often conduct events on the same day and since our societies are sharing the launch areas and have many common interests, the RRS will work with FAR to find the best approach to assure safety and smooth operations for all.

[2] Next events at the MTA

Frank Miuccio is already working on the next event with LAPD CSP. The program will likely have its first class possibly on the Friday after the Martin Luther King holiday. Five to six weeks later means that the launch event could take place in late February or early March 2020.

I’ve been planning a launch event at the RRS Mojave Test Area (MTA) much sooner than that. For too many years, the RRS MTA sits empty in January and February for no good reason. I sought to undo this trend by holding an event just with our membership the way that our society used to operate.

At first, I was able to confirm Wolfram Blume who wants to fly his booster and ramjet upper stage system, if only for a system test of his booster, staging mechanism and recovery system. The ramjet upper stage will not be fired and will be loaded with an equivalent weight of water in its gasoline fuel tank to get the correct balance of the final vehicle. It’s a bit of risk to fly the actual ramjet prototype but there is no better way to get the right aerodynamics. It should be a good test and with luck his systems all pass the first flight test at the RRS MTA.

Larry and I have been talking about integrating a commercial hybrid motor into his 38mm fiberglass rocket. If I can acquire the motor parts, Larry will help me get the recovery system and the rest of the motor mounting complete. This will be the first hybrid motor launch from the RRS MTA in a very long time.

Also, John Krell voiced his interest in re-flying his improved avionics payload in an RRS standard alpha. This one will have an expanded accelerometer range to catch the ultra-fast burn of the alpha. He’s working on improving the data rate as recent open-source software changes have downgrading the sampling by half for some inexplicable reason.

Brian Johnson and Bill Behenna each have avionics packages in development. The RRS has plenty of alpha boosters ready if members can get their payloads integrated into a suitable payload tube in time. We hope to confirm the launch manifest by New Year’s Day so I am hopeful we will have a fun launch day on January 18, 2020. We have also spread the word to our university project teams that the RRS MTA will be open for testing or flights if they can be ready on this date early in the year. The RRS encourages all teams to plan ahead and test early and often to assure their later success.

[3] Progress on the 2020 RRS symposium

Frank Miuccio, our vice president and symposium coordinator, has had some difficulties in confirming the symposium date, but we are hopeful that the April 18, 2020 will be the symposium date. We also may have the option for April 25, 2020. The Ken Nakaoka Community Center of Gardena will hopefully confirm the date for our symposium Monday.

The Long Beach Rocketry group and the Compton College STEM club have both indicated their interest in presenting or exhibiting at the 2020 RRS symposium. In many cases, it can be first come, first serve. This will be the fourth symposium in a row for us and we hope to continue the momentum we’ve built. I have a few government and private companies in mind to give us a great slate of speakers. We just need to confirm the symposium date.

[4] Treasurer’s report on the membership roster, dues payment policy change

Chris Lujan has been surveying the sign-up sheets from past months over recent years to help establish who has been attending meetings and how often. Active membership requires participation in the society as it does with any group. Attending monthly meetings is not the only means of staying active as attending launch events or participating in outside events also qualifies. The RRS is working on building a firm definition to make clear when a member is or is not active. This is important as our Constitution requires both an administrative membership class AND active membership to retain voting rights. Each year, we try to reach our past and present members but without effort on the member’s part to keep their information current, our elections and voting on important measures must go on without them. Contacting any member of the RRS executive council is the best way to keep the society updated on your whereabouts and contact information.. The membership roster is managed by the RRS treasurer.

treasurer@rrs.org

Chris is also working up some percentages for how many of our active membership are current with their dues payment. Initial estimates are encouraging, but since we have many new members who paid upon their induction, these high percentages make sense. It is our longer term members who are often neglecting their duty to keep their dues paid each year. Dues payment is also an essential element of membership.

The executive council has voted a policy change to when dues are to be paid. Effective immediately, all dues payments must be made by January 1st of each calendar year. I was glad that the society has supported this firm fixed date which makes accounting for dues much easier on our treasurer. The membership roster will also track dues payment and active membership status. For the several lifetime members in the society, this past membership class will remain and dues payment is not required for these persons, however, remaining active with the society is still a requirement to keep voting rights.

[5] 2020 Constitutional Committee report

Frank Miuccio was able to report that the 2020 Constitutional Committee has met a couple of times in the last two months and is reviewing the last page of the new draft. The committee will present its draft to the executive council at year’s end. The executive council will review the draft before presenting it to our administrative membership for consideration and a subsequent two-thirds ratification vote.

[6] Social media updates

Our social media coordinators were both not in attendance in December. The RRS continues to be active on Instagram. Our Facebook page needs some management. The RRS is also looking at trying to build a calendar feature on the RRS.ORG website to better announce events.

secretary@rrs.org

The RRS continues to use WordPress for its ease of use and simplicity, but the society has been considering reformatting and restyling our page or at least re-organizing the menu options to make finding common things easier. This will be a task for the new RRS secretary.

[7] CSFM committee on amateur rocketry

The California State Fire Marshal’s (CSFM) office has been holding hearings with the broader pyrotechnic operator’s community throughout the state this year. Most of the community is made up of the fireworks and special effects community. Amateur rocketry is a smaller and separate group which has our own interests we operate very differently from the other larger groups.

The RRS (Larry Hoffing), ROC (Chris Kobel) and FAR (Mark Holthaus) discuss a collective list of proposed changes to CSFM definitions governing amateur rocketry on 12/04/2019.

Mark Holthaus of FAR has been reviewing the definitions pages of the California laws relevant to amateur rocketry. The RRS and FAR have met on three different occasions in the last two months. The RRS has found FAR’s proposed changes to be very reasonable and accurately reflect how we can continue to operate safely. We have also included feedback from members of the Rocketry Organization of California (ROC) at the last two meetings. David Reese of ROC has been particularly helpful in improving and clarifying the language which governs our hobby and we are also grateful for his assistance.

Mark has made arrangements to discuss our proposed changes with the CSFM office on Monday, December 16th. We hope this informal meeting goes well and that all of our recommendations can be implemented which will assure both safety and legal operations for our groups. Some of the amateur rocketry groups are not national organizations and would be harmed by excessive regulation from the state. The CSFM office has been very welcoming and open to ideas thus far. CSFM has not often held these kinds of reviews and the RRS recognizes the great opportunity we’ve had to help shape policy for everyone in rocketry in California.

[8] RRS executive council election results for 2020

Larry Hoffing, our appointed election chairman for this annual election cycle, certified his results to the membership at our December 2019 meeting as required per our Constitution. Each officer was elected by unanimous vote. Our new executive council officers starting in January 1, 2020 are as follows:

Osvaldo Tarditti, president@rrs.org

Frank Miuccio, vicepresident@rrs.org

Drew Cortopassi, secretary@rrs.org

Chris Lujan, treasurer@rrs.org

The RRS is grateful to our election chairman, Larry Hoffing, for fulfilling his duties to the society. The council will appoint a new chairman next November when we hold nominations for the next election cycle. The society is thankful to our new and returning officers who have stepped up to serve the society for this next exciting year, 2020.

[9] Proposed RRS MTA standard fee schedule

The RRS has become increasingly active with more and more requests to use our Mojave Test Area (MTA). This is a very good thing, but often scheduling of hot-fire events has become excessively chaotic. The RRS understands that sometimes things happen that can force cancellation of a planned event with little or no notice. Weather is often the main culprit of such things. However, as one who has participated in coordinating launch events at the MTA this year in conjunction with our RRS president, I have seen many occasions when poor planning is the only reason for a last minute cancellation. Worst yet, the society has also received far too many last minute requests for use of our site. The RRS is in the process of drafting a standard fee schedule which will explain the requirements for outside users of the MTA. The exact details of this forthcoming policy are still under discussion, but the following is some of the ideas that were discussed.

The RRS is happy to help as many organizations as we can, but our customers must understand that:

(1) We are a volunteer society. Few, if any, of us are paid for the substantial time and resources spent to make these events possible. While we often generously donate our time to support and promote these events, the society needs money to operate and improve our site and this must come from charging fees to pay for repairs improvement projects. A standard fee schedule will be drafted, reviewed and approved by the society before the end of the year.

(2) We operate the RRS MTA by APPOINTMENT ONLY! There is no sign-up calendar like what is used by other amateur rocketry organizations such as FAR. We operate in this fashion because we stress the importance of advanced planning. Last minute requests for using the MTA site will very likely be rejected. Rocketry is a dangerous hobby and the importance of careful preparation is reflected in the desire of the RRS to accept only advance notification for all proposed projects. This not only makes planning events easier for all parties, but it makes them safer. Contact the RRS president for all requests to use the RRS MTA.

(3) Our indemnification forms are required to be signed and submitted by ALL PERSONS well in advance of attending the event. This includes spectators, spouses, significant others, and children. This has been standing policy at the RRS MTA and will remain so. Just showing up at our MTA site on the day of the event is NOT acceptable and people will be turned away if our policies are not respected.

(4) We expect several weeks advance notice to conduct a thorough review of each new project. This means that all groups must have their operating procedures, checklists, drawings, schematics already prepared for the pyro-op’s review when the request is submitted.well in advance of the requested event date. Expecting the pyro-op to examine your intended test article and procedures for the project only on the day of the event upon their arrival is NOT REASONABLE.

Events at the MTA will be conducted with a pyro-op appointed by the RRS. Our pyro-op should have had the opportunity to see everything well planned and well in advance. Attending RRS monthly meetings is an excellent way for potential users to familiarize themselves with the society and our expectations. Submitting your project description on an RRS standard record form a month in advance and was formerly policy at the RRS. Everyone must understand that the pyro-op in charge can refuse any test at any time for any reason making your journey out to the MTA all for naught.

Based on an accumulation of both good and bad experiences, I will undertake a project to draft an official RRS policy on testing at the MTA for our outside customers that will take affect on January 1, 2020. I was glad to get a lot of feedback from potential customers and other members at the December meeting. To our society members, please send me your feedback soon as I will be working this policy out in the next two weeks before the executive council approves it.

The RRS will begin charging standard daily fees for use of the MTA site and charging a separate daily fee for the pyrotechnic operator in charge at this event. Pricing may vary with private companies and universities, but in all cases, fees are expected to be paid before approval of the event is given by the RRS. Cancellations within two weeks of the event will result in forfeiture of all of those fees for that event date and new fees must be paid again for a new test date. When customers stand to lose their fees if they fail to deliver on their commitments to the RRS, they will better understand the importance of managing their projects better as they must now avoid the cost of cancellations. Other groups, both amateur and professional organizations, operate successfully with these kinds of policies and the RRS will be enforcing their own policies soon.

[10] Review of the Gas Guzzler ramjet project

Wolfram Blume and his wife were kind enough to stop by the December RRS meeting bringing his booster rocket for one more inspection. I will be the pyro-op in charge of his first test flight on 1/18/2020 and I wanted a closer look at how secure and stiff his fins were. Based on my inspection, his booster looks ready for rail launch. With luck, his staging and recovery systems will function without issue. Wolfram has borrowed from prior successful designs flown at ROC events in Lucerne Valley. The RRS is glad to assist him with this ambitious project.

Wolfram Blume stands with his booster used on the Gas Guzzler project.

[11] Solid propellant making classes

The RRS was approached about restarting our composite grain propellant making classes at the RRS MTA. After some careful assessment of our equipment, resources and available personnel, the RRS is not yet ready to offer these classes again. Twenty years ago, the society held a few of these solid motor building classes which became very popular. The RRS is building back our capabilities and this will take some time.

The Friends of Amateur Rocketry (FAR) has offered similar classes at their site and for the time being, the RRS must refer interested parties to them.

[12] SuperDosa project update

The SuperDosa project was established two years ago with the intent of the RRS restarting our large solid motor building skills to progressively build larger vehicles able to not only breach the von Karman line (100 km ASL), but surpass the current amateur rocketry altitude record holder. Despite our increasing membership, we have not had much progress to date. Given my commitments to several liquid rocket projects, I am handing over my leadership duties to Drew Sherman. Drew is a founder of Leo Aerospace and also an active RRS member. His interests very much align with this project and with the combined resources of others in the society building high powered motors, we hope that Drew can continue this project to its lofty goal of bringing the title back to the Reaction Research Society.

[13] RRS MTA facility improvements

Osvaldo Tarditti, our society president, continues to lead our MTA facility improvement projects, chief among those is improving our bathroom facilities at the site. Osvaldo has drafted plans for an improved bathroom facility at our remote RRS MTA site. The RRS will be soliciting bids from local contractors soon and we hope to commence this important improvement at the MTA sometime this spring and complete by the summer. The society has nearly enough funds for this project, but we are hoping to receive a few more thousand dollars to initiate this project sooner than later.

Also on our list of improvements is a blockhouse replacement, horizontal mounting plate at our testing area to create a regular interface pattern for future users rather than continue the unregulated drilling of anchor bolts (and the hated “male” variety of these anchor bolts) into our concrete slab. RRS members, Dmitri Timohovich and Wilbur Owens have been supporting the society on this improvement as it will require heavy equipment to place and secure this trench plate at the RRS MTA.

Larry Hoffing has recognized that the society will soon need a second 40-foot container for storage. We will be acquiring some new solid propellant mixing equipment and we need to rearrange our inventory in a more organized and accessible fashion. Whether this comes in the form of a new container on our MTA site or possibly one given to us from our site tenant, Polaris Propulsion Inc., remains to be seen. The society will continue to monitor progress and set goals to complete these tasks.

IN CLOSING

This will be my last monthly report as I am stepping down as secretary of the RRS. I have enjoyed serving in this role for the last three years, but it is time for me to allow a new secretary to lend his voice to you, our readers. I will remain active with the society, but only as a member engaged in many projects around the society. The society grows as we bring new members in and the society gets new ideas. It is also important that we also get new leadership from time to time. I hope to see more of our new administrative membership step up for these executive council roles in the future. There is no better way to help the society than with service.

As my last parting comment, I would encourage ALL of our membership to write and submit articles. The RRS.ORG website is one of the best ways we educate and inform the public about the things that interest the society in rocketry. Even simple academic subjects are excellent ideas. Next year, you may see a couple articles from me, but I want to encourage all of our membership to do more than just mention ideas in conversations, but write them down, text them, email them, convey them to the RRS secretary. It is the job of the RRS secretary to be the chief editor and means of publication for our membership. Past articles are welcome as we have re-printed ones from our long past. We also heartily welcome new content. Any time is a good time to submit.

Our next meeting will be held January 10, 2020, at the Ken Nakaoka Community Center at 7:30PM. If there are questions or corrections, please notify the RRS secretary. After January 1, this will be Drew Cortopassi.

secretary@rrs.org

With gracious thanks to the society, I hope to see everyone in the new year.

October 2019 meeting

by Dave Nordling, Secretary, Reaction Research Society


The Reaction Research Society (RRS) met for our monthly meeting on Friday, October 11, 2019. We had a full agenda with three presenters and a lot discuss with upcoming events. 

We had a few new people come to our meeting including Frank Chandler who works with the Cal Poly Pomona liquid rocket project.  Frank joined the RRS as a member and we hope to see him and his students at future meetings and launch events.

Frank Chandler and Frank Miuccio talk after the conclusion of the October 11, 2019 meeting

We were also happy to have several Compton College students from their newly formed STEM club attend our meeting.  The RRS is glad to support the efforts of university students in their ambitions to build liquid rockets and we’re happy to add Compton College to the growing list of organizations we support.

RRS members Jerry Fuller and John Krell listen to Wolfram Blume’s presentation at the October 11, 2019 meeting.

We called the meeting to order and after the reading of the treasury report, we started the first of our presentations.

[1] The Gas Guzzler Ramjet Project

Wolfram Blume is a new member to the society and he has been working for over eight years on a unique kind of rocket project that has been very rare in the long years of our society and probably in amateur rocketry as a whole.  His two-stage rocket consists of a first-stage solid rocket booster using a commercial grade motor and a gasoline-fueled ramjet engine as a second stage.  Both stages have a parachute recovery system and an onboard fuel management system. 

Wolfram Blume holds his 3-D printed fuel manifold at the inlet of his ramjet engine
Wolfram pulls his recovery system from within the ramjet engine to show how it is stowed and deployed with a redundant firing system.

Wolfram’s presentation was very thorough as this project is very complex.  The RRS is still assessing the project in all of its aspects.  With Wolfram’s permission, we’ll share the full set of details in a separate report here on RRS.ORG.  The Gas Guzzler project still needs several more static tests conducted to prove key parts of the combustor.  Flight tests of a dummy, unfueled ramjet and the solid booster are also being discussed.  We hope to share more details as this exciting project evolves.

The RRS is happy to consider propulsion projects of all kinds, but every project must be peer-reviewed by the RRS before it is accepted for any testing at the MTA.  Testing at the RRS MTA is by appointment only.  All persons and groups interested in testing at the RRS MTA must submit a standard record form and all details of their proposed project. Our standard record form is available for download on our RRS.ORG website.  These materials must be submitted to the RRS president and after careful review that a test can be scheduled.

[2] Bill Behenna, Avionics Payload for the RRS standard alpha rocket

With the many school events we’ve been having through the LAPD CSP, we have had many alpha rockets getting flown out of the MTA.  The payload tubes are typically empty which creates a great opportunity for others to build and fly payloads in these small but powerful rockets being launched many times throughout the year.

Bill Behenna has been actively working on making a customized instrumentation package that would fit within the small confines of the long alpha payload tube.  Barometric pressure measurements, accelerometer readings and air temperature would be recorded on a solid-state memory chip which have been shown to survive even the harsh sudden stop into the dry lake bed floor if the parachute recovery system fails.

Bill Behenna’s breadboard of his instrumentation payload is taking shape.

Bill talked about his testing with his breadboard model using Arduino modules and an UNO microprocessor.  These instrumentation packages can be challenging to make, but they can offer a lot of great information on the flight.  The quality of data collection devices are ever increasing and the size and price of these instruments are ever decreasing.  It is a great time to be in amateur rocketry.  Many commercially available rocket instrumentation packages exist and are used more and more frequently in model rocketry.  The particular challenge with the RRS standard alpha is its compact size and metallic construction.

John Krell and Bill Behenna discuss their instrumentation packages before the start of the meeting in October 2019

[3] Review of John Krell’s Flight Data

In parallel to Bill Behenna’s efforts, John Krell has been working on a slim instrumentation package that measures the three-axis acceleration, barometric pressure and air temperature readings.  He conducted several tests of his system which was able to record data and a speed sufficient to capture the rapid combustion of the alpha flight.

John was able to get his first prototype, actually two prototypes, ready to fly in alpha rockets #9 and #10 at the September 21 launch event.  More importantly, the rockets were located downrange and extracted intact for examination.  The data confirmed that the burnout velocity is in fact subsonic, the burn time is just short of 0.40 seconds and the altitude of both rockets is around 4000 feet. What is surprising is that the maximum acceleration from the alpha exceeds even the 100G limit of the sensor.

John Krell begins his presentation at the October 2019 meeting of the RRS about the flight data captures in two RRS alpha flights on 9/21/2019 at the MTA

John’s report was very thorough and with his permission, the RRS will publish the full details of his project in a separate article here on RRS.ORG.  The most important thing is that John is already building more units for more rocket flights that will take place at another launch event at the MTA.  With more data, the flight parameters of the RRS alpha can be even better resolved.


[4] RRS presents at the CATIE conference at Antelope Valley College

The RRS was asked by Dr. Khalil Dajani to present at the California Aerospace Technology Institute of Excellence (CATIE) at the Antelope Valley College (AVC) in Lancaster, California on September 18, 2019.  The conference was an event for government and commercial companies in the Antelope Valley to network and to forge beneficial partnerships in the aerospace industry.  

I had asked Drew Cortopassi to attend the conference on behalf of the RRS.  Drew was also able to attend the conference on behalf of the Aerospace Corporation as he works in the Propulsion Testing Lab in El Segundo.  The RRS introduced ourselves as an educational non-profit group with resources that can help government and commercial companies with modest testing facilities.  The RRS was also proud to share with the audience our long history in the pursuit of reaction propulsion and research.

Drew Cortopassi summarizes his experiences at the CATIE conference at AVC on behalf of the RRS.

[5] RRS social media

Alastair Martin is one of our two social media advisors to the RRS.  As part of our regular monthly agenda, he briefed our audience on our Instagram and Facebook sites that we maintain along with the main website.  Alastair’s company, Production Tribe LLC, is producing the Rocket Talk Radio podcast which includes RRS members and discusses current and historical topics related to rocketry.

[6] RRS launch events at the MTA

The RRS had a successful launch event with Boyle Heights on September 21 as detailed in a prior firing report.  The RRS is glad to announce that another launch event will occur at the MTA before the year’s end.

The RRS program at Boyle Heights was a success. The air launcher is a great teaching tool.
The balloon on a string is another great illustration of the jet propulsion principle.

Frank Miuccio, our society vice president and our point of contact with the LAPD CSP, announced the next educational event will begin on October 25, 2019.  This 5-week course will be with 99th Street Elementary School in Watts.  The final step is the launch event at the RRS MTA on December 7, 2019.  The exact number of rockets is not known yet, but we are expecting 10 alphas.


[7] The RRS history project

The RRS history project is an on-going task to archive and collect all historical materials.  George Garboden has graciously donated a large number of documents to the society for storage, archival and scanning.  The RRS is glad to accept these materials to help bring more of our history to more of our members.  More than just the careful preservation of the reports and papers, is the larger task of sorting and scanning them.  We hope to enlist more of our membership to devote the time and care needed for the long-term success of this project.


[8] Update from the 2020 Constitutional Committee

The RRS Constitution is in the process of being revised to better reflect how the society functions today and making important clarifications of parts that were somewhat ambiguous.   This three-person committee was appointed by the executive council in February this year and consists of one executive council member, Frank Miuccio, and two of our administrative members in the society. 

Drew Sherman, Frank Miuccio, Mike Albert and Mohammed Daya listen as John Krell makes his presentation to the RRS on October 11, 2019.

The painstaking task of going through every page and every paragraph of the Constitution is almost half finished.  After a complete review of the whole document, the committee will present it’s findings and a recommended draft to the administrative membership for their questions and comments.  This was hoped to be completed by November 2019 with the goal of attempting ratification by the new year, 2020.

The committee has decided to continue the use of an RRS policy listing which would contain the more specific or quantitative aspects of the society such as the annual dues amounts.  Simpler and less categorical changes could be amended more easily by the council or by the administrative membership.  The Constitution itself requires a higher level of approval for any changes which includes a two-thirds majority vote by the administrative membership.  There will be more on this subject when the committee completes it’s initial task hopefully by next month’s meeting in November 2019.


[9]  The 2020 symposium

The RRS agreed to hold the next symposium in 2020 continuing the annual tradition.  Our membership commitment to making this next symposium an even larger and greater success is strong.  Frank is working on confirming the next symposium date which may be March 28, 2020, if the Ken Nakaoka Community Center can confirm.  The society will try to hold this event a little earlier in the year to hopefully avoid the onset of the warmer temperatures.  The community center does not have air-conditioning and we do expect a larger crowd as this has been the trend since we restarted symposium events in 2017.


[10] The treasurer’s report on membership

Chris Lujan, the RRS treasurer was not able to provide his report on our membership roster and status.  We hope to bring this report to the next meeting where we will show how well the society is doing in keeping current with receiving annual dues payments and show how much our membership roster has grown in these last few years.


[11] Reminder for annual nominations for RRS Executive Council at the November meeting

Per our Constitution, the RRS will be taking nominations for each of the four executive council positions at the RRS.  Positions are only open to administrative members of the RRS, and we have been expanding our ranks with former administrative members returning to active status and newer members being inducted in the last two years.  Nominations can be made at the next meeting of the RRS, November 8, 2019.

The 2019 RRS Executive Council: Dave Nordling, Osvaldo Tarditti, Frank Miuccio and Chris Lujan

With nominations received, the RRS will appoint an election chairman, to conduct the voting process with the results announced at the December 13, 2019 meeting.  All elected executive council members will begin their new terms at the start of the new calendar year, January 1, 2020.


[IN CLOSING}

This October 2019 meeting was one of the best we’ve had since my time with the RRS.  A lot of great projects are in the making and we’re getting more and more data to share with the society.  The society is growing and we’re glad that our enthusiasm is spreading.

The next meeting will be November 8, 2019, on the second Friday of each month as usual at the Ken Nakaoka Community Center in Gardena.  If there are any questions about this October meeting, please contact the RRS secretary.  Hope to see everyone back again in November..
