January 2018 meeting

The RRS met for its monthly meeting, Friday, January 12, 2018, at the Ken Nakaoka Community Center in Gardena. We got a late start (8:04pm), but we covered a lot of ground.

Anniversary issue of the Astro-Jet is now available for purchase ($10/copy)

Everyone is reminded that the anniversary issue of the ASTRO-JET newsletter of the RRS is now available for $10 a copy. This special issue will be available in print only and proceeds go to benefit the society and our upcoming symposium event. Bill Janczewski and I have worked hard to bring this milestone issue together and we will have them ready for printing and distribution next week. To order, you can contact me by email (secretary@rrs.org) and send me your mailing address. Payment can be made by check to the “Reaction Research Society” sent to our P.O.

Frank brought one of George Dosa’s liquid rocket chambers to the meeting for inspection by the society. This single element coaxial injector has not been fired, but George had this made several decades ago. There was talk about what modifications could be made to get this article into hot fire.

Richard Garcia also brought his own liquid rocket chamber as part of the on-going RRS standard liquid rocket project he has been championing.

After the usual reading of the treasury report, we began to discuss the agenda topics. The meeting began with announcing our new members who have recently joined us: Michael Lunny, Bryan Calungcagin, Nancy Squires, Barsoum Kasparian and Jack Oswald. The RRS is glad to welcome our new members.

The discussion had turned to membership cards. Bill Janczewski has worked up a new card design and Frank was working with Bill on a few changes. The RRS does not issue membership cards except on an on-demand basis. RRS member, Alastair Martin who runs a printing business had several ideas for different types of card stocks and discussed them with the RRS.

Larry Hoffing had asked about getting a short run of business cards to support his role as the RRS events coordinator. Frank had said he has the resources to get these made.

Our discussion then turned to the upcoming RRS symposium to be held Saturday, April 14, 2018. We will try a new format of having our speakers present in the ballroom among our exhibitors. The collared white shirts we gave to our membership running the event was a good idea. We discussed getting these again with iron-on or screen-printed RRS logos to help identify those of us who will be running the event. Frank wanted to have posters showing a decade-by-decade look of the RRS over our 75 year history. This is a great idea and we’ll be working hard to collect old photos to have them on display at the symposium. Easels and other supporting equipment were in short supply as the brick walls of the Ken Nakaoka Community Center made wall-mounting very difficult.

For next meeting, we will discuss more of the details of the symposium including working on our list of presenters and exhibitors. Frank and I have already began to approach some of our prior speakers and exhibitors. We have already confirmed several from industry, government and academia including the LAPD CSP program and the Aerospace Corporation. We expect this year’s symposium to be even greater than last year’s event where we hosted over 200 people.

For the next agenda item, Frank and Larry will begin our next educational event with the students of Florence Joyner Elementary school in conjunction with the LAPD CSP program. This 5-week event will begin sometime in February with an expected launch event in late March. Alastair had indicated he’d like to participate, film and document this event. An update on this event will be given at the next month’s meeting.

Michael had indicated his interest in running an RRS educational event with his old high school, Redondo Union High School. Larry and Frank had offered to help him figure out how best to set this up based on the experience the RRS has had thus far. I had sent him the PowerPoint file I had made which can serve as the basis for the program he can give to an older group of students. This would be the first of several events that Michael and Bryan would like to hold on behalf of the RRS.

Our next agenda topic discussed establishing an account with the regional liquefied natural gas (LNG) supplier, Clean Energy in Boron, California. Richard Garcia has acquired a methane dewar which will be used for liquid rocketry experiments at the MTA. Richard was able to have one of our contacts at the Friends of Amateur Rocketry (F.A.R.) group modify the dewar such that it is ready for use. Our president, Osvaldo, said he would contact Clean Energy and give them the necessary information for the RRS to begin buying quantities of methane.

The next agenda topic was the quarterly briefing of the SuperDosa project. Osvaldo and I have identified chemical suppliers to produce the RRS standard solid propellant mixture recipe. We will meet offline to discuss prices and what is the best approach to proceed. Richard was going to work out some more simulations of our proposed vehicle to get an idea for sizing. The ballistic evaluation motor (BEM) that I designed is still in work. This is an important piece of hardware to characterize the burn rate of our propellant to help finalize and set the grain design. I hope to complete the assembly before the symposium which would also be the next quarterly reporting date (April 13, 2018).

The last agenda item was to discuss how to formalize the proposal process for RRS projects that we would like to seek funding from outside groups. One of the most important things to getting projects funded is to have a clear plan on what the scope of the project is, what purposes it will serve, what exact materials and quantities will be required and what the expected cost of this project will be using real quotes and defensible estimates. The RRS was in agreement and the executive council will meet later to discuss some of these documented proposals I have assembled. Projects include things like making more alphas and beta rockets, 3D printer for RRS use, spare electric generator for the MTA, getting a new launch rail built as backup, obtaining a liquid oxygen dewar…. etc.

The night ran late and our meeting concluded at 9:10pm.

There’s a lot of preparation that must be done in advance of our 75th anniversary symposium on Saturday, April 14th, so we’ll be putting this recurring item on the agenda for next month’s meeting.

For next month’s meeting, Frank will finish his paper rocket air launcher device that he has been making. This was inspired by the last educational event with Grape Street Elementary where the students visited the Space and Missile Command Center at Los Angeles Air Force Base in El Segundo, CA. With luck, we hope to demonstrate it outside the community center and take some video for our YouTube channel.

Also, for next month’s meeting, I had promised Frank and Osvaldo that I would bring in my alpha parachute assembly that I have worked into a PVC payload tube. I have resolved some of the issues with my timer circuit, but I am still looking for access to a 3D printer to produce my internal umbilical switch mount.

As always, if there is anything here I have missed or misstated, please let me know. Our next monthly meeting will be held, Friday, February 9, 2018. Hope to see you there.

July 2017 meeting

The RRS held its monthly meeting last night on July 14, 2017 at our usual spot at the Ken Nakaoka Community Center in Gardena, CA. We got started a little late, but we covered all of our agenda items.

We have two new members, Drew Cortopassi and Alastair Martin, joining the RRS. Both were in attendance at the meeting and we were glad to have them join us.

Larry gave us an update on the RRS alpha build event we’re doing with the students of Jordan Downs in Watts. John Mariano gave his presentation last week and Larry has started the build event portion. This event has been sponsored by the Los Angeles Police Department’s Community Safety Partnership (CSP) which will be bringing a lot of talented kids from the inner city of Los Angeles. Local television crews filmed the event and the final day of painting of the student rockets is happening today. We hope to have the video spot on our YouTube channel very soon.

To any school or private group that would like to conduct a rocket build event with the RRS, please contact us at:
events@rrs.org

I will be launching an alpha of my own at the event with a PVC payload section. Our director of research, Richard Garcia, and RRS treasurer, Chris Lujan, were helping me with some payload issues I’m resolving.

Dave Crisalli has also been working with students at the Chaminade College Preparatory School in Chatsworth, CA. They have built a solid rocket motor to test at the MTA on the July 22nd event. Dave was a graduate of Chaminade and has been our pyro-op on many MTA launch events.

Chaminade College Preparatory School

Our discussion moved to the details of managing the upcoming launch event at our Mojave Test Area (MTA) on next Saturday, July 22nd. This is a private event, but we host these with many students, universities and private individuals with our membership.

We had discussed how the launches should be conducted as early as possible to avoid what will likely be an oppressively hot summer day for our young students. All of our invited attendees should make an extra effort to be at the MTA by 10:00AM, which means leaving the city before 7:00AM. There were also concerns related to safety once we get into launch mode. Once the safety briefing is conducted (likely around 11:00AM) and all people are moved into the observation bunker, the roads will be closed to traffic. No one will be allowed in or out until the last volley is fired as is our policy.

Attendees at the MTA are recommended to wear hats and sunscreen at all times. Bring as much ice and water as you can. And most importantly…drink this water and fluids as often as possible. Many people don’t know they have become dehydrated until after the ill-effects set in (then its too late). Drink often even if you don’t feel like it.

I gave a short update on the SuperDosa project. We have decided to build a ballistic evaluation motor (BEM) to have the ability to conduct propellant evaluation tests. There are a few different approaches to getting accurate burn rate data, but I felt that the BEM approach would be the most beneficial despite the added complexity. Osvaldo has the plate and round stock I bought for this small but tough little test rig. Richard Garcia is working on the dust recovery and ducting to restart his graphite machining capabilities. I hope to get a few nozzle pucks made and hopefully begin testing this fall.

RRS ballistic evaluation motor design concept

More work in trajectory and performance modelling needs to be done. The details on the initial SuperDosa design are still a bit in flux. Neither Richard nor I had any progress to report on this front.

The discussion moved to propellant procurement. We are looking at acquiring some AP oxidizer which shouldn’t be a problem. The HTPB binder chemical, however, has really climbed up in cost. PBAN is another option we’re considering. Someone mentioned asphalt was used in the early days, but it’s not clear what the disadvantages are.

We had briefly discussed making rocket candy just for the initial samples to test and qualify the BEM test rig. It was decided that Chris Lujan would cook a small batch of sugar/KNO3 at the MTA and pour into some 3/4″ PVC sample cases. I hope to be able to document the process and present this in a report. This is a common mixture, but the purpose is to help more people become better at this task. Many of our members have experience in making the rocket candy mixture, but it helps to standardize the process and always watch out for safety issues.

MIT student, Sean Austin, was in attendance at the meeting. He had mentioned his university lab had built a strand-burner to test propellant samples. They had a lot of issues getting reliable test results, but he was happy to share their design with the RRS. A strand burner design is simpler to make and if the RRS has the right materials and tools, we may build a strand burner to supplement our BEM.

Richard Nakka’s rocketry page has a lot of great details on this subject of solid propellant burn rate testing methods and data collection.

Four members from the UCLA IREC team came to present their results from this year’s competition at Spaceport America north of Las Cruces, New Mexico. The rocket launch competition is supported by universities across the country and the event is managed by the Experimental Sounding Rocket Association (ESRA).

I had asked UCLA to come show us the fruits of their team’s hard work done at the RRS MTA. UCLA had some issues resolved, but ran into other problems at the launch site. Heat was a factor which resulted in the payload computers not working. A great deal was learned and UCLA will surely leverage these lessons into next year’s build.

The RRS would like to thank UCLA students, Nakul Gupta, Caleb Lessard, Edward Shen and Nick Knenning for presenting. The RRS looks forward to continuing our support of UCLA and other universities as they advance their rocket projects.

The UCLA Rocket Project will conduct more cold flow testing of their liquid rocket systems at the RRS MTA at the July 22nd event, but priority will be given to the student alpha launches to conduct the events as early in the day to avoid the hottest hours at the site.

Also, in attendance at the meeting was MIT student, Sam Austin. Sam is in Los Angeles this summer on an internship with Northrop Grumman. Sam was part of the MIT team at the IREC competition and related some of his team’s results. MIT did well taking 2nd place, but as always, there are new things to learn or things to do better. Sam had indicated interest in attending the upcoming launch at the MTA. We hope he’ll become a student member of the RRS to do so.

The RRS history project continues as our current membership has been reaching out to our founders and other members from the earliest days of the society. We hope to share some of this with our readers and members very soon. Frank had found another set of RRS newsletters from 1989-1991 which he gave to Richard Garcia, our director of research, for scanning and archiving.

As always, if anyone has any RRS or related literature that they would like to offer to be scanned for the society, please let Richard know:
research@rrs.org

I had presented the general topic of how to generate more revenue for the society. The RRS is funded by our membership in the form of dues, donated time to support events, monetary and material donations and such. I wanted to solicit ideas about how the RRS can pursue other avenues to bring in more funds to better support the programs we have and the new programs we hope to do soon.

One classic idea is to produce RRS-logo branded things like T-shirts, coffee cups, even metal rulers. I have seen older RRS branded items in the past and although the profit margins can be thin, it’s a fine fund-raising idea to consider. John Mariano had a few other ideas for fund-raising he brought up in a previous meeting this year.

The RRS is looking at grant programs both in the private sector and with government agencies. The RRS is a 501(c)3 educational non-profit group which has had success with several schools already and we intend to expand our outreach as we find schools and organizations able to help us bring the joy of rocketry. Donations from private companies and individuals is another avenue we’ll pursue. If anyone has any specific programs or ideas in mind, please contact the RRS vice president, Frank Miuccio.
vicepresident@rrs.org

One idea I had which was accepted was to publish an issue of the RRS Astrojet newsletter on our 75th anniversary on January 7, 2018. Although the RRS has not published a paper newsletter in quite some time, it was a popular item in its day. The newsletter would be the same 12 page format used throughout our history with articles from many of our members including George James, George Dosa and others as we bring this idea home. The 75th anniversary Astrojet newsletter will only be available in print and delivered by mail for a nominal price ($10?) to help fund the RRS’s growing activities.

Another idea put forth was to attempt the rocket mail flights done in the early days of the society. More thought and discussion would be necessary to see how feasible this would be, but I liked the idea?

The RRS may look to have some corporate sponsorship of the 75th anniversary symposium if this is possible.

***

Frank made the announcement of the upcoming 75th anniversary RRS symposium on April 14, 2018. This will be a public event at the Ken Nakaoka Community Center where we will have speakers from universities, government agencies and private companies.

Frank also mentioned that he’ll be taking a trip to JPL with RRS founder, George James, later this month. Besides a tour, the RRS hopes to have a conversation with the K-12 education outreach coordinator at JPL on this visit. Frank will post an update on the website after this event.

We adjourned late, 9:20PM, well after the 9PM closing time, but we covered a lot. If there is anything I missed or misstated, please contact me at my RRS email below.
