November 2019 meeting

by Dave Nordling, Secretary, Reaction Research Society


The Reaction Research Society (RRS) held it’s monthly meeting on November 8, 2019 at the Ken Nakaoka Community Center in Gardena, California. The society had a full agenda plus our annual nominations for the executive council. Frank Miuccio attempted to establish a teleconference at the meeting to connect our director of research, Richard Garcia, and an outside organization that wanted to address the society. This teleconferencing was successful and the society will consider having more of these to help bring in more participants on special topics.

[1] Treasurer’s report on membership and dues status

The RRS treasurer is conducting a review of our membership roster to not only update our records with the many new members that have joined us this year, but also to determine the dues status for each. Like in all non-profit organizations, regular annual dues payment is essential to keeping the society funded for the many projects we do and are planning. Upgrades at the MTA are also impacted if our membership does not keep their dues payments current.

Chris’s report was not ready at this month’s meeting, but he will be soon notifying some of our delinquent members that they need to keep their dues paid to remain in active status. It is the duty of all RRS members to keep their contact information current with the RRS treasurer. The society can not be responsible for missing communications if our members do not do their part by making communication possible. Also, members who are not current in their dues payment risk losing their active status with the society.

treasurer@rrs.org

I have always paid my dues to the society on January 1st of each new year. This greatly simplifies the process and I need no reminder to do so. Membership dues ($40 USD per year) to the society can be paid through the “Donate” button on the RRS.ORG website which links to Paypal.

We remind all of our donors and those paying dues in this manner to include your name in the “Notes” section along with the purpose of your donation. Without including your name, the RRS can not tell who has paid their dues.

The RRS.ORG website has more information on this subject. For any questions, please contact the RRS treasurer.

[2] Update on the next RRS MTA launch event with LAPD CSP and 99th Street Elementary School

Frank, Larry and Osvaldo are in the middle of another class, this time with 99th Street Elementary in partnership with the Los Angeles Police Department (LAPD) Community Safety Partnership (CSP). The class is going well and the final launch event is still planned for Saturday, December 7, 2019.

At this same launch event, we are also planning to host the University of Southern California’s (USC) Rocket Propulsion Laboratory (RPL) with the launch of their latest solid motor powered rocket. USC has been making continuing progress even after their landmark flight to be the first university-built rocket to break the von Karman line into space.

[3] Preparations for the 2020 RRS symposium

With the society approving the symposium for our fourth year in a row, Frank is working with the Ken Nakaoka Community Center to establish the date. Tentatively, the 2020 RRS symposium will be held Saturday, March 28, 2020. The society has decided to try to hold the symposium earlier in the year to avoid the onset of the summer heat which makes the event very uncomfortable in the absence of climate control at the Ken Nakaoka Community Center.

Future site of the 2020 RRS symposium

More information on this subject will be posted as it develops. Our symposium coordinator for the 2020 event will again be our society vice president, Frank Miuccio.

[4] RRS solid propellant making classes at the MTA

The RRS has been approached by an outside organization about conducting solid propellant motor making classes. Many years ago, the RRS held a few of these events which became very popular. The RRS has not yet decided if we will restart these classes, but a group is examining the possibility and will report back to the society on the viability of such a project.

[6] Annual elections for the RRS executive council

As required by our Constitution, the RRS appoints an election chairman to oversee and execute the process of nominations and balloting for each of the four executive council offices for new terms starting in the new calendar year. Larry Hoffing, again, agreed to be our election chairman for this cycle.

Nominations were held and were open to our administrative membership. Nominations were received and our election chairman will be sending out ballots by email. This is another good example of why all members should keep their contact information current and remain in active status with the society. Balloting will be closed prior to the next monthly meeting in December and the results announced at that meeting.

[7] CSFM committee on amateur rocketry

Last month, the RRS and Mark Holthaus of the Friends of Amateur Rocketry (FAR) met to discuss a list of proposed changes to the California State Fire Marshal’s (CSFM) definitions that govern amateur rocketry. This small group was intended to be made from active amateur rocketry groups around California to help advise the CSFM subcommittee on changes that would help improve regulation of amateur rocketry and make needed clarifications to help all groups continue to operate safely and legally.

from left to right, Mark Holthaus (Treasurer of FAR), Osvaldo Tarditti (RRS president), Larry Hoffing (RRS events coordinator), Dave Nordling (RRS secretary) meet to discuss proposed definition changes to CSFM laws governing amateur rocketry, 10/15/2019

The RRS and FAR held a second meeting at the Ken Nakaoka Community Center which included David Reese of the Rocketry Organization of California (ROC). ROC members, Chris Kobel and David Reese have been very helpful in providing helpful improvements to how the certain classes of rocketry are defined.

This amateur rocketry committee will be presenting their collective suggestions to the Fire Marshal in early December 2019. The RRS, FAR, ROC and the rest of the amateur rocketry groups in California are glad to assist the CSFM office in making these suggested updates.

[8] Social media updates

There was no report from Alastair Martin and/or Bill Janczewski this month for social media improvements for the Reaction Research Society. We hope to have more to discuss in the next month on this regular topic. As always, members are welcome to offer their advice and proposals to either or both of our media coordinators.

Alastair and I did have a conversation about expanding our following on Instagram. We will continue to show the highlights of our events and the people involved, but I hope to bring more technical content which seems to be our primary source of interest.

Alastair and his production company, Production Tribe LLC, has created yet another podcast in the “Before SpaceX” series with special guest, rocket propulsion expert, author and RRS member, James R. “Jim” French. RRS secretary, Dave Nordling, and RRS director of research, Richard Garcia, supported this excellent discussion about the American Rocket Company (AMROC), a space start-up company in the 1980’s and 1990’s. The show is still in editing and will be posted very soon his website.

[9] Compton Comet STEM club formation and program

Several students from the Compton College STEM club attended the November meeting of the RRS along with their advisor and fellow RRS member, Kent Schwitkis. Jamie Alvarez, the STEM club president was in attendance. The Compton Comet is the project name for the liquid rocket projects that the Compton College team is working on. There are about 20 students in the group and the RRS is glad to support this team and the other university teams looking to compete or at least expand their range of practical skills.

The Compton Comet team has been holding meetings at Tomorrow’s Aeronautical Museum (TAM) at the Compton/Woodley airport. They are planning a few trips to inspect launch and additional hardware assembly sites and make a report back to the RRS at the December 2019 meeting. RRS member, Waldo Stakes, has also been an important part of this program.

The STEM club is having another Estes rocket competition later this month. The first of these events was very successful. Part of the experience is getting practice with the simpler rockets and using OpenRocket simulation software to make and verify predictions.

IN CLOSING

RRS members, Frank Miuccio, Alastair Martin and Kent Schwitkis contributed to this report. The next RRS meeting will be December 13, 2019. If there are any corrections or additions to make for the monthly report, please contact the RRS secretary.

September 2019 meeting

by Dave Nordling, Secretary, RRS.ORG


The Reaction Research Society (RRS) met on Friday, September 13, 2019. We had several new people come out to visit including the CSU Long Beach liquid rocket team. They were coming to learn more about the society and our resources at the Mojave Test Area (MTA).

The RRS had a special occasion to celebrate at the meeting which we did with pizza. The RRS now has three new licensed pyro-ops, Osvaldo Tarditti, Larry Hoffing and Dave Nordling. This will help us a lot in holding more events at the MTA.

Abel, Wally, Tustin and Hunter from the CSULB Beach Launch Team, enjoyed our celebration and stayed for the meeting.

Since we had so many new people coming to the meeting, we decided to make introductions and share some of the stories and latest projects before getting to the meeting agenda topics.

Wolfram Blume, new member to the RRS, discussed his plans to static fire a gasoline fueled subsonic ramjet

New RRS member, Wolfram Blume, came to the meeting tonight to discuss his plans to build, test and ultimately fly a gasoline fuel ram-jet called the Gas Guzzler project. He’s been working on this project since 2011 and he presented the RRS president with his test request to conduct a static fire test along with many details of his initial designs. The RRS has not tested a ramjet in many years and this will be a very interesting project as it develops.

Waldo Stakes, RRS member, explains his latest progress with the steam rocket he’s been working.

Waldo Stakes came to the meeting to share with the society his latest progress with a steam rocket he’s been working on for Mad Mike Hughes. Waldo’s projects are always fascinating as he’s worked with a lot of different groups over the years in racing and in rocketry. He’s also been working with Compton College on the planning of their large liquid rocket. The RRS is also glad to be a part of Compton College’s ambitions to build a liquid rocket.

Mario and Oscar of Compton College with RRS member, Kent Schwitkis listen to Bill Behenna present his latest avoinics payload project to be built for the RRS alpha.

RRS member, Kent Schwitkis and a couple of his students from Compton College came to the society meeting. There are many bright students at Compton College interested in working with the RRS and we have already began to assist each student with tasks specific to projects their working at the college.

Bill Behenna shows his latest prototype of an alpha payload to measure acceleration and barometric pressure.

We decided to showcase our membership project first before beginning our agenda which was a very good idea. Bill Behenna has been hard at work on his avionics payload to be built to fly in the many RRS standard alphas we have at most of our launch events.

After calling the meeting to order and the reading of the treasury report, the RRS began our September meeting agenda.

(1) Next Launch Event at the RRS MTA with LAPD CSP and Boyle Heights

The RRS has finished with the last classroom presentation of the series. The students have painted their rockets and are ready for the final launch day, next Saturday, September 21, 2019. After propellant loading, the RRS will be ready to receive our next group to watch their handiwork take flight in the desert.

(2) RRS facility improvements

Osvaldo has been leading the task of evaluating facility improvements to the RRS. The main improvements under consideration are (1) improving our restroom facilities at the MTA and (2) replacing the old blockhouse at the MTA. Osvaldo has made some drawings of the new restroom facilities and is discussing the details with a vendor to get a quote.

In early August, our large adjustable rail launcher was damaged in a failed launch attempt of a large solid motor. Osvaldo began repairs and hopes to have the box rail system restored soon.

The RRS MTA site was also the victim of theft of many things from the George Dosa building. Security at our test site is difficult given its remote location. Several suggestions were made including adding cameras, improving our locks and doors, making opaque window inserts for the building, and simply being present at the site more often. The RRS has been the victim of theft before, but it is something that is never easy to recover.

(3) 2020 Constitutional Committee report

The committee was not able to make their report this month. Several factors have contributed to this delay over the summer. The committee will make its presentation to the society at the next meeting in October.

(4) Society votes on holding the 2020 RRS Symposium

After some discussion last month, the society decided that we will in fact hold the next RRS symposium in the Spring of 2020. Given the increasingly successful events we’ve had since 2017, and the many people who have encouraged us to keep this annual event, the administrative membership voted in favor. Frank Miuccio will again be our symposium coordinator and the RRS will be reaching out to presenters and exhibitors very soon. Our next order of business will be setting the date which is likely to be in the month of April.

(5) RRS to present at the CATIE conference at Antelope Valley College

Dr. Khalil Dajani of CSU Long Beach has invited the RRS to be one of the presenters at the Space Responsiveness Workshop and Exhibit at Antelope Valley College at the Hellenic Center in Lancaster, California. The 2019 California Aerospace Technologies Institute of Excellence will be held on Wednesday, September 18th where members from industry and the government will hear our presentation introducing the society and our capabilities at the Mojave Test Area. We hope to make some great contacts at this event and begin some new partnerships..

(6) RRS social activities in planning

The RRS has focused a lot on educational and project activities, but we don’t often plan simple gatherings for fun. Larry had talked about having the RRS visit Mt. Wilson as a private group. At the meeting, we also talked about having a simple barbecue at the MTA as was done in times past. We plan to revisit this discussion again. Other members are welcome to share their ideas.

(7) RRS history project – Garboden archives

Lifetime member, George Garboden, has many boxes of papers and reports from the RRS in his possession that he would like to pass back to the society for archival. In support of the RRS history project, the society is always glad to get articles, clippings and any kind of archival materials and make them more available to our membership. Frank, Larry and I have been working on the logistics of getting a new storage location, but the most important step is finding the time to carefully make quality scans.

(8) Social media improvements

Alastair Martin announced the next pending episode of his podcast, Rocket Talk Radio. Other fellow RRS members, Dave Nordling and Richard Garcia, will take part in the next installment of the “Before SpaceX” series on September 28th. In this episode, we will be interviewing Jim French. Jim has had a long and interesting career as a rocket development engineer for the H-1 and F-1 engines at Rocketdyne in the 1950’s and later at TRW in the 1960’s with the Lunar Descent engine during the heyday of Apollo. His book “Firing a Rocket Engine” is available on Amazon.

“Firing a Rocket” by James French

Jim French also worked for a startup company called the American Rocket Company (AMROC) in Camarillo in the late 1980’s and early 1990’s. We hope to have a great conversation and learn a lot about his experiences at this commercial space company.

(9) Memories of George Dosa

As our last order of business, we shared with the society that we lost one of our oldest and most beloved members of our society. In our long history, George Dosa, had a profound impact on the society and many of our past and present members.


The RRS adjourned our meeting after a long series of very interesting discussions. We are thankful to all for coming and we will be holding our next monthly meeting, October 11, 2019. If there are any changes or additions to make to this monthly report, please notify the RRS secretary.

MTA launch event, 2019-07-13

by Dave Nordling, Secretary, RRS.ORG


The RRS was glad to have another launch event at our Mojave Test Area (MTA) on Saturday, July 13th. Our event this time was with Operation Progress in Watts. Thanks to our partnership with the LAPD CSP, we are able to fly nine alphas and a beta rocket at this event. It was to be a typically hot July day in the Mojave, but the winds were still through the morning picking up a little as the afternoon went on.

This was my first time as the event pyro-op. New member, Kent Schwitkis of Compton College and Waldo Stakes assisted me with the operations as we gave our young rocketeers a great view of their hard work.

As the LAPD CSP arrived at the RRS MTA, the society prepared to give a site tour to the students followed by our safety briefing.

The students of Operation Progress take some shelter and hydrate under the cover of the George Dosa building.

Our sample propellant burn demonstration gave the students a visual indication of what would be to come with the propellant driving their custom painted rockets into the blue sky. With the briefing and demonstrations complete, the students took shelter in the observation bunker.

RRS members, Kent Schwitkis and Dave Nordling loading an alpha for Operation Progress

One of the interesting features I noticed with this set of alphas was the use of modelling clay at the nozzle to hold back the micrograin propellant. This proved to be an equally effective method of holding back the propellant when the rocket is in firing position as the typical phenolic thin disks we commonly use.

The electric match lead wires emerging from a wad of modelling clay used to hold back the micrograin powdered propellant. The hole seen in this photo was smoothed over by a gentle brush of the finger. The method proved to be very effective.

An alpha streaks away almost perfectly straight in the nearly still winds.

One of the alpha rockets was outfitted with a whistle on one of its fin. Although imparting a spin during flight, the alphas tend to remain somewhat stable in flight. The results from this flight was somewhat disappointing as the whistle could not be clearly heard in either ascent or descent before impact.

Our last rocket for Compton College was the larger RRS standard beta rocket. This two-inch diameter powerful vehicle made its impressive mark on the launch pad as it tore into the sky. After the launch, we took break for lunch. With the day growing hotter by the hour, our partners with the LAPD CSP and Operation Progress bid the MTA and the RRS farewell as they returned to the city.

Still capture of the beta flight from Frank Miuccio’s cell phone video footage from the bunker.

Following lunch, our second group at the event was a team from Compton College made up of Prof. Kent Schwitkis and Brian Johnson and their students. The Compton Comet was a standard alpha rocket outfitted with an instrumentation package and a parachute.

The team discusses the assembly and operation of the payload in the Compton Comet.

New RRS member, Professor Kent Schwitkis got his first experience with loading the micrograin propellant in the Compton Comet at our loading area. This is a rite of passage for many of our new members. Although old and grossly inefficient, the zinc and sulfur powder propellant combination offers a simple and powerful combination to lift rockets in a yellow rushing plume.

After loading the propellant tube, the team begins their final assembly by mating the payload to the coupler.

The Compton Comet was loaded by the team into the alpha launch rails. All of us retreated to the concrete bunker for firing.

The team puts their hands on the rocket one last time before going to the pad.

The Compton Comet parachute somehow failed to deploy. The ballistic return of the rocket meant extraction by the time-honored method of shoveling. The Compton College team showed tremendous fortitude in the scorching 110 degree weather. The fruits of their labor was the return of the instrumented payload including the data chip inside.

Recovery of the Compton Comet by shovel.

Initial results showed that data was taken throughout the flight. The results are being reviewed by Compton College to be reported later to the society.

This was a very successful launch day at the RRS MTA and the society was glad to support the Operation Progress and Compton College student teams at our Mojave Test Area. For more information on similar rocket building programs with the RRS, contact our events coordinator, Larry Hoffing.
