December 2018 meeting

Posted on by

The Reaction Research Society (RRS) held its final monthly meeting of our 75th anniversary year, 2018, on our usual 2nd Friday, December 14th.

We were glad to be visited by Waldo Stakes, Curator of the Saxon Museum in Boron, California, and well-known rocket car maker. Wilbur Owens was kind enough to bring Waldo to the meeting.

The agenda for December was kept short as the RRS wanted to take some time to celebrate our accomplishments this year.

After coming to order and the reading of the treasury report, we began the shortened agenda.

[1]
The results of the elections were announced by email from our election chairman, Larry Hoffing, who could not attend. The full slate of officer candidates were voted unanimously with no write-in’s.

The RRS officers for 2019 are as follows:

President – Osvaldo Tarditti
Vice President – Frank Miuccio
Secretary – Dave Nordling
Treasurer – Chris Lujan

We thank our appointed election chairman, Larry, for his service.

The newly elected officers will start their new terms at the beginning of the calendar year. All of our appointed positions at the RRS remain the same as the executive council has voted to retain them. We are thankful to all of our new and continuing membership for making this an important milestone year for the society.

The next topic was to discuss the UCLA hot fire event at the MTA in November. Osvaldo was very impressed with the UCLA team in how well they communicated and their preparation for a safe hot-fire test. Despite having an earlier setback, they recovered to have a hot-fire in the early night hours that gave them valuable data for their next design iteration. The RRS is glad to support university groups with our testing site. It is great when everyone puts safety and organization first.

The RRS has had other university groups express interest in using our Mojave Test Area (MTA). To any groups wanting to use the RRS MTA, please contact the RRS president by email.

president@rrs.org

We also appreciate each group filling out our RRS standard record form to help explain the basics of what they would like to accomplish. The standard record form can be found under “Forms” on the RRS website.

[3]
The last of the scheduled agenda topics was the announcement of the official date of the 2019 RRS symposium. The symposium will be held on Saturday, April 27, 2019, at the Ken Nakaoka Community Center in Gardena. As before, we will have entire first floor and outdoor courtyard.

The 2019 RRS symposium will be held on Saturday, April 27, 2019

The RRS has had great success in getting a range of speakers from industry, academia and government agencies. We plan to invite the Navy China Lake, Air Force Space and Missile Center, NASA Goddard Spaceflight Center, Northrop Grumman, Relativity and the Additive Rocket Corporation just to name a few, as well as several of our local and regional university rocketry groups such as UCLA, USC, Cal Poly Pomona, CSULB and LMU just to name a few. In the new year as invitations go out and we get confirmation, we will update our agenda for the April symposium. We hope to have an even larger turnout both on our stage, at the exhibition and of course our public audience.

The RRS will be holding a 2-hour panel session as the final event in our speaker series. The RRS is working on building this panel from a good cross-section of industry, government and academia to look at the state of affairs in space today and looking ahead to what may come next as the industry expands.

To those who stayed to the end last year, we were provided a rare treat by former member Bill Claybaugh as he presented his assessment of the current aerospace industry. We would strongly encourage everyone to plan to stay the full day as we will be bringing out more special things as the day goes on.

[9]
This topic was on the original agenda, but we thought we wouldn’t have time. RRS member, Alastair Martin, through his company, Production Tribe, is starting a pod-cast called Rocket Talk Radio. RRS director of research, Richard Garcia, and the RRS secretary, Dave Nordling, have agreed to be the first guests on this pod-cast that will talk about current topics in space and rocketry. As the first few podcasts are made, he’ll look to have other guests, to talk for an hour over a range of questions posed by Alastair and the participating audience.

[X1]
Osvaldo went over the long list of events we held at the RRS starting with the Aerospace Corporation launch test of their prototype liquid-hybrid rocket motor, the three launch events we held through the LAPD Community Safety Partnership (CSP) program where we were able to engage 112 kids in the at-risk communities of Watts in Los Angeles. Both USC and UCLA had a lot of success in their respective rocket programs.

Although USC did have a major setback in their Traveller III flight, they are well positioned for a very successful flight on their long journey to be the first university group to break the von Karman line into space with their boosted dart. The RRS is glad to be recurring partner with USC by assisting with their ground testing needs.

UCLA has also had a successful year with their liquid rocket programs and the RRS is glad to continue our support.

New RRS member, Dmitri Timohovich, and myself journeyed out to the MTA on December 2 for a site improvement project to mount the new road sign we had made. As I was feeling very under the weather on that afternoon, Dmitri did a stellar job in helping the society put a visible marker at our big iron gate leading the way into the RRS Mojave Test Area (MTA). The RRS thanks Dmitri for his hard work for the society.

[X2]
RRS member, Jack Oswald, presented his current progress with his large solid motor building project. His team have been working hard this year having some successes and failures, but always learning. His new ballistic evaluation motor design will correct some of the prior deficiencies in the earlier design and is expected to produce high quality results that should finalize his motor design. Jack and his team from the former Chaminade rocketry group have made a lot of progress and have also helped me with my smaller BEM design. Based on our conversation at the December meeting, I think I will have to re-visit some of my assumptions. Many thanks to Jack and his team’s hard work in supporting the society with their ambitious goals.

[X3]
RRS director of research, Richard Garcia, was not able to attend the December meeting, but he did provide a progress update for the RRS standard liquid project. His injector and chamber design is nearly finished and seems to have all the right features to proceed with build. The injector design is based on a previous design used by the RRS in past liquid rocket projects. He is also re-using his ablative chamber liner feature for this smaller 125-lbf LOX-ethanol engine design. His analytical model of the propellant blowdown system seem to anchor his predictions for what will hopefully be a successful hot fire test in this coming new year, 2019. The RRS is working hard to anchor a reliable and simple to build liquid rocket engine system that university groups can use for liquid rocket competitions in the future without having to start completely from scratch. We will provide updates as this project advances.

[X4]
Richard also brought up the idea of building a rocket sculpture to the right of our big iron gate at the MTA. The society welcomed the idea and we hope to bring this concept to life sometime very soon.

[X5]
Lastly, Frank was presented with a Community Service award by the Los Angeles Women Police Officers and Associates (LAWPOA) to honor the continuing work of the Reaction Research Society with the LAPD CSP. It is with great pleasure that the RRS accepts this recognition and reaffirms our commitment to this strong program that has done a lot of good for the young minds we hope to inspire.

Bill Janczewski holds up the LAWPOA Community Service award presented to the Reaction Research Society; I think I caught Frank a little off-guard in this photo? He was very pleased.

Our next monthly meeting will be on Friday, January 11, 2019. For an update on our intended agenda for each meeting, check the RRS.ORG website under the “Forum” section.

We look forward to starting the new year with preparations for the 2019 symposium and we will need our full membership to help make this event an even greater success.

Also, the RRS is talking about holding one of our monthly meetings at the Tomorrow’s Museum at the Compton Airport. Also, Jack Oswald has been working on getting tours of The Boring Company in Hawthorne and the Point Mugu Naval Base sometime in the new year.

The RRS wishes everyone happy holidays and a happy new year.

Spaceport L.A. holds its Rocktoberfest event at Relativity Space

Posted on by

The Reaction Research Society (RRS) was very fortunate to attend an event sponsored by Spaceport L.A. This “Rocktoberfest” event held on November 15, 2018, was at the Relativity Space offices in Inglewood. This was a sold-out event with many people present from industry and the space-loving public.

Spaceport L.A. is an organization aiming to unite, build and support a space professional community in the thriving heart of Los Angeles. Through discussions, meetings and events held by Spaceport L.A., their aim is to propel further innovations and potentially foster breakthroughs to enhance space exploration. Members include technical professionals from all disciplines and other passionate individuals with the same aim to support the space community. The RRS naturally fits with these goals and we hope to have Spaceport L.A. participate at the 2019 RRS symposium at the Ken Nakaoka Community Center in Gardena in April (exact date to be confirmed soon).

Spaceport L.A. – main website

The event brought a good crowd with people from Virgin Orbit, SpaceX, Phase Four, Aerospace Corporation and other professional organizations. The pork schnitzel offered from the food truck outside and the beer served at the event made for a fine supper before the panel discussion that was to take place.

Contrary to the hopes of many, Relativity did not offer a tour of their facilities at the event, but several members of Relativity were in attendance including former University of Southern California (USC) Rocket Propulsion Laboratory (RPL) member and Chief Technical Officer (CTO) of Relativity, Jordan Noone. I had a chance to talk with Jordan and his new Director of Propulsion at Relativity, Nate Scholten.

Also, in attendance at the event was Mike Kwapisz, Vice President of Engineering at Phase Four (P4). Phase Four is an El Segundo based start-up company making a new RF-based electrode-less, electromagnetic-based propulsion system. The “Maxwell” engine is designed for high reliability, long operating life and is modular for smaller low-power satellites to larger spacecraft systems.

The panel discussion had many fine speakers representing a wide swath of newer aerospace industries. Tim Buzza, former SpaceX manager and now a director at Relativity Space, gave a very insightful talk about his early days at SpaceX with the Falcon 1 and the trying times they had in bringing a new launch vehicle to the market.

Dr. Greg Autry, also on the panel, is a founding director of the Southern California Commercial Spaceflight Initiative at the USC Marshall School of Business. He offered many great insights about how the commercial space market has grown from once a purely speculative concept to an expanding and thriving industry in the United States and abroad.

Spaceport L.A. panel discussion, Marco Villa (Tyvak), Tim Buzza (Relativity Space), James Behmer (Phase Four) and Gene Autry (USC) with Curtis Iwata moderating.

James Behmer of Phase Four was also on the panel and shared a bit of their history in bringing a new modular propulsion technology into the growing small satellite market.

Lastly, Marco Villa, Chief Operating Officer (COO) of Tyvak Nano-Satellite Systems, was on the panel sharing his insights from his previous days at SpaceX as the Director of Mission Operations. Dr. Villa https://www.woltherchiro.com/prednisone-over-the-counter/ also talked about how Irvine based, Tyvak is developing nano-satellites for the growing market. He also mentioned an interesting statistic that today there are over 100 companies world-wide that are endeavoring to offer access to space. In an age of consolidation, it is good to hear how the market is expanding in some respects.

The panel discussion was fascinating and I hope Spaceport L.A. will sponsor another event soon. I am very thankful to Curtis Iwata and all of the volunteers at Spaceport L.A. for coordinating a great evening that fostered many great discussions with more to come in the future. I have left a link to the Spaceport L.A. website above and a few links below to the companies represented on the panel. Also, I am grateful to Relativity Space for opening their doors for this networking event through Spaceport L.A. It was a fascinating night.

October 2018 meeting

Posted on by

The RRS met for our monthly meeting on Friday, October 12, 2018, at the Ken Nakaoka Community Center in Gardena. As usual, we got started by calling the meeting to order and reading the treasury report. We had a big agenda but covered most of the topics.

[X1]
Richard Garcia wasn’t able to join us at the October meeting. He wanted to report that he has made some design improvements to the RRS standard liquid rocket. He’s finished upgrading his engine design code to be able to analyze a blowdown engine (pressure-fed from the tanks). He also will soon have drawings for a thrust chamber design.

With some luck, I hope he’ll be back into testing at the MTA sometime soon next year.

[X2]
Electro Tech Machining (ETM) in Long Beach, California, specializes in graphite stock, graphite parts and Electrical Discharge Machining (EDM). They are experts and have been a loyal supporter of amateur rocketry groups such as UCLA and USC. The Reaction Research Society is happy to endorse them as they have been a great support to our society member’s projects as well.

I stopped in this week to pick up some round stock for making more graphite nozzle pucks for the ballastic evaluation motor (BEM) that is nearing completion. Graphite makes an excellent high temperature material for nozzle throats or any low ablation surfaces. We have used graphite inserts into reclaimed alpha and beta nozzles over the years at the RRS. Our society members have used graphite throats in their larger solid motor tested at the RRS MTA back in June 2018.

Moving into the meeting agenda, we shifted the order a little, but I have kept the numbering the same:

[1]
The latest educational event at Weigand Elementary school in Watts is going very well. The LAPD CSP program continues to help sponsor the event and we get great excitement from the kids. This Friday was the fifth of six educational events where they get to assemble the empty rockets. Osvaldo, Larry and Frank were on hand to help with the build process. The kids are really enjoying the process of learning and painting the team rockets will done in the last session before going out to launch at the RRS’s private testing site, the Mojave Test Area (MTA).

[2]
The next launch event at the RRS MTA will be the final step in the RRS’s educational program for Weigand Elementary school. We have this scheduled for October 27th and we hope to have cooler weather than in prior events now that the summer has passed. We have nine alphas from Weigand Elementary and three more alphas from our new membership, Wilbur Owens, Xavier Marshall and Michael Lunny.

I gave my quarterly briefing on the SuperDosa project at the October meeting. This time, I organized my thoughts and ideas into a presentation to give the RRS a general overview of the project and where we are so far.

Largely, I wanted to reiterate the project’s overall goals to many of the new members who have joined the RRS since the project’s inception in January 2017. The RRS intends to retake the amateur rocketry altitude record and in the process reopen our ability to make larger solid rocket motors and expand our reach both in our own community and literally with payloads ultimately flying above the atmosphere.

SuperDosa quarterly report, Oct-2018

I also acknowledged the recent progress of some of our new members formerly of the Chaminade Rocketry Club. Also, USC had a launch attempt with their Traveller III rocket, part of their Spaceshot Initiative. Unfortunately, instrumentation was not functioning but the flight looked to be nearly perfect. I hope USC will come present their recent accomplishments at a future RRS meeting.

Materials acquisition and some discussion about how to proceed with the propellant burn rate testing were the highlights of the discussion. More progress needs to be made in a few areas for completing the first prototype:

(a) Complete the design of all parts for the first prototype (6-inch booster)

(b) Begin prototyping instrumented dart payloads to practice flying and recovering these while getting good data. Making these devices work under the tight and unforgiving conditions that they must.

(c) More work in parachute recovery

(d) Estimating friction heat loads and heat mitigation strategies for the payload

Much of this prototyping work can be done at the MTA by flying smaller subscale vehicles and testing subsystems to prove they can work. More importantly, these tests give the society practice for the large vehicle testing which will reclaim the altitude record for the RRS.

The response to the SuperDosa project’s progress was very constructive and many new ideas were offered. I’m thankful to Frank, Steve Majdali, Larry, Osvaldo, Bill Behenna, Drew and Xavier for their inputs. I have taken notes and given actions to other members who are willing to help advance key areas of the project. Unfortunately, this topic was to be the last of the evening as my presentation easily exceeded the 20 minutes I intended.

The next quarterly report for the SuperDosa project will be January 11, 2019, and I hope to report a great deal of progress.

[4]
We had a last minute addition to the agenda, with Steve Majdali talking about black powder rockets and some very nice black powder rocket making tools he acquired while on travel. Black powder rockets are a classic form of amateur rocketry and involve many techniques that are broadly useful in other areas such as composite grain motors.

Steve Majdali shows the RRS his metal spindle for a cored grain type of 3-inch black powder rocket

Steve gave us a lot of great information specific to black powder making, pressing and a wealth of other practical information. Based on this new avenue of research, I felt the RRS would benefit more if Steve discussed this topic in more length in a stand-alone article soon to be published here on the RRS.ORG website.

[5]
The RRS has been in contact with the Additive Rocket Corporation (ARC) of San Diego. They are a startup company in San Diego with the goal of making high performance rocket motors using their novel design methodologies and 3D metal printing equipment. Discussions are still underway and thus there wasn’t much to tell. ARC was an exhibitor at the 75th anniversary symposium this year in April.

[6]
In my discussions with ARC, they were kind enough to offer to 3D print a simple small liquid rocket chamber I designed. Prices are not cheap, but this futuristic manufacturing technique offers a great deal of complexity that is not easily nor cheaply replicated by traditional means. I have been in discussions with ARC and hope to have more to present at the next RRS meeting.

[7]
Alastair Martin could not join us at October’s meeting. I was going to have him discuss the current topics of interest at the recent 21st Annual Mars Society Convention held this summer. Alastair is very involved with the Mars Society and the RRS.

Alastair will be at the November RRS meeting so we’ll put this topic on the next agenda.

[8]
New RRS members, Wilbur Owens and Xavier Marshall, are active with the Experimental Aircraft Association, chapter #96, at the Compton Airport in the Los Angeles area. EAA-96 is a like-minded group of enthusiasts centered on experimental aircraft. The EAA-96 has hangar space and a range of machining tools offered to their members.

Experimental Aircraft Association, Spirit of 96

Xavier had mentioned at the last meeting that the EAA would love to host a visit by the RRS. Accepting the EAA’s invitation, the RRS has scheduled a visit to the EAA in Compton on November 3rd at 10:00AM. The EAA will give an hour tour of their facilities and projects. We hope to foster a strong relationship between the EAA and the RRS.

Talk with Xavier Marshall, Wilbur Owens, the RRS president, vice president or secretary for details.

Compton, CA, 90220
(310) 612-2751

One of the key points of discussion at this visit will be to discuss how the RRS and EAA can help each other or participant in joint projects. The RRS is interested in using the EAA hangar facilities if they are available. Annual membership at the EAA is $40 to the EAA national society and $40 more to the local chapter at the Compton Airport. As I understand but must confirm, with EAA-96 chapter membership, RRS membership can have access to the machining tools for building rocketry parts for those of us without facilities in our own homes.

Xavier had also mentioned that hangar storage was often very cost-effective which could be a service that the RRS could use as we look to expand our shop capabilities to our membership.

EAA Chapter 96 hangar, Compton Airport

The EAA hangar is just straight east and not very far from our regular meeting location in Gardena at the Ken Nakaoka Community Center just north of Artesia Blvd. (CA-Hwy 91). The address is above.

[9]
Osvaldo’s recent successful design of an alpha parachute recovery system was not able to be covered. We may expand this topic into a fully illustrated RRS.ORG article if we can not get this topic on next month’s agenda. This has been a quiet success and definitely worthy of exhibition to our membership.

[10]
Jerry Fuller of Aerospace Corporation had indicated interest in building and testing a larger subscale prototype of his liquid-infused hybrid motor grain. Aerospace had earlier this year successfully demonstrated a smaller prototype in flight at the RRS MTA. In choosing the next larger design, he has selected a common model rocketry size (98 mm) just under 4-inches which will allow him to use commercially available rocket body parts. Jerry is active with our friends at Rocketry Organization of California (ROC).

At this time, he is still working on the design until resources can be allocated. The RRS has invited him to present his results and the new prototype he has in mind. The RRS is happy to support private groups with a testing area and a community of amateur enthusiasts happy to assist.

[11]
The RRS had discussed having a small group of our membership go out to the next ROC event which is held the 2nd Saturday of the month. Unfortunately, neither I nor Drew were able to go this month. With the Friday night rains falling on the city, it might not bode well for the event at the Lucerne Valley as they must operate on the dry lake bed.

We are looking to coming out to the November ROC event in the Lucerne Valley and hope we can bring other RRS memmbers with us. In particular, some of our members are interested in getting more practical experience through the NAR or Tripoli prefect at ROC. Moreover, some of the RRS membership is seeking experience and support as we acquire letters of recommendation for the California pyro-op licensing in rocketry.

[12]
Saturday seminars have not yet been scheduled, but the RRS is still committed to offering an extended time period for fuller discussions by invited speakers.

[+] RRS member, Jim French, is a speaker of which we would be very excited to have. Jim was a development engineer at the famed Santa Susanna Field Laboratory here in Los Angeles during the development of the reliable and powerful H-1 engine and the injector for the massive F-1 engine. Later, he worked at TRW on the reliable, hypergolic fueled, Apollo Descent engine at TRW at their San Juan Capistrano testing site (now defunct). His book, “Firing a Rocket Engine” is available on Amazon and it is a great read.

Amazon.com – James A. French, Firing a Rocket Engine

[+] Reaction Research Society founder, George James, is another speaker we have been wanting to have. His founding work with his other organization, the Rocket Research Institute (RRI) was a great topic he covered only briefly at the 75th anniversary symposium in April.

[+] Rocketdyne retiree and materials expert, John Halczuk, is another potential speaker on the subject of his extensive research of the V-2 rocket. He gave an excellent talk last year at California State University in Northridge, on history of the V-2’s development and deployment. The V-2 guided many design decisions still used in modern rocketry today in both the United States and particularly in the former Soviet Union.

We were not able to discuss this topic in detail, but more information will be forthcoming, hopefully in the form of an announcement of our first Saturday seminar at the Ken Nakaoka Community Center on a Saturday morning.

[13]
The next RRS symposium date in 2019 will be set soon. Based on the powerful success of the 2018 event, the RRS has decided to further the tradition one more year. We hope to have an even better mixture of universities, private companies and government agencies.

Date to be announced in November, the RRS will hold the 2019 symposium at the Ken Nakaoka Community Center in Gardena

There was no time to formally raise the subject, but it was decided by the council members present at the October meeting that the 2019 RRS symposium date will be formally set by an offline discussion and the date officially announced at the next RRS meeting on November 9, 2018.

[IN CLOSING]
The next meeting of the RRS will be November 9th at the Ken Nakaoka Community Center in Gardena.

We will most certainly discuss the results of the MTA launch event scheduled for Saturday, October 27, 2018. I will build the agenda starting at the end of the month. Please contact the RRS secretary for ideas and information on meeting topics.

secretary@rrs.org

As per our constitution, the RRS will hold its annual nominations of officers for the next calendar year 2019 at the November 9, 2018 meeting. Voting by the administrative membership will take place thereafter and managed by our election chairman. Results will be announced at the next meeting on December 14, 2018.

Thank you for reading.
