June 2017 meeting

The monthly meeting of the RRS was held June 9, 2017, at the Ken Nakaoka Community Center in Gardena. The meeting was called to order at 7:45pm.

The launch event with UCLA was successful. We accomplished a lot with many different groups present. Again, we thank Dave Crisalli for being our pyro-op for the event. The RRS discussed the event and how we could manage these events in a more orderly fashion.

Several steps for improvement were discussed including tighter control of incoming vehicles and setting our operating procedure into written form for publication. In the future, the RRS should require all attendees to the MTA send their indemnification forms well in advance of the event so we know how many people we are expecting. Also, we need to use a full 10 second count instead of the 5 second count which will allow more time for the spotter to stop the launch if a problem is detected. An earlier draft of the RRS operational safety codes exists and was approved. The RRS secretary will circulate a new draft to the executive council before the next meeting on July 14th.

Minor facility improvements were discussed including how to mitigate the stifling heat at our desert site. Frank was willing to buy a water-fed misting fan that might help some people inside the Dosa building or perhaps inside the bunker. If the device works well, the RRS may consider buying a second unit to help create a small cooling space for those who are most affected by the heat.

I sat in my truck’s air conditioning a few times that afternoon as wearing the fireproof suit for the micrograin loading operations only added to my mounting heat exhaustion. Dave Crisalli had mentioned there are vests that hold flat ice packs that can be worn inside of protective suits. This will buy some time to work more comfortably under hot conditions.

Hydration, sunscreen and proper clothing for the desert heat are always important to all individuals to protect themselves both before and during the events held at the RRS MTA. The Mojave Desert is a tough place. It’s this attention to these details that are key parts of everyone having a successful event. As we do operate year-round through the hot months, there will always be this hazard to manage.

We reviewed the video shot from the launches. It has been suspected that the existing micrograin launch rails are a little too short resulting in the rockets leaving less than straight from the rails. We discussed newer longer rail launchers. It was decided to try to recover an old rail system that is already at the MTA as a backup.

Frank brought several old paper copies of the RRS newsletters. Some of these date back to the early 1950’s and others were from the 1960’s. The RRS is actively working to electronically archive as much of these newsletters as part of our on-going RRS history project.

RRS News, Issues 98 and 101

Issue 101 mentions a story where the RRS was on the old Louis Lomax show which was a local semi-weekly news program in Los Angeles from 1964-1968. John Mariano and George Dosa were there and we hope to someday find the archival footage and post this to our YouTube channel. (I think it was Issue 101? Someone correct me if I am mistaken.)

The RRS has in fact set the date for the upcoming 75th anniversary symposium which will be April 14, 2018. We will have it at the Ken Nakaoka Community Center as before. We have already begun the process of contacting speakers and exhibitors. We hope to make this event even better than this last year.

John Mariano brought his rocket on a string. This is a classic demonstration of the fundamental principle of propulsion using a CO2 cartridge guided on a plastic clothesline. The rocket was easily able to traverse the full length of the Ken Nakaoka Community Center ballroom, even uphill to the stage where Larry was holding the stop. Bill and I took video of the event and its on the RRS YouTube channel. Link is below:

After some false starts in getting the spring loaded puncturing device to work, we got it to work. Simple, but very fun! This demonstration of the fundamental principle of jet propulsion is a favorite in our educational events.

The RRS is looking forward to doing an educational event with the students of Nickerson Projects in Watts. After the teaching sessions, the launch event is scheduled for July 22nd. Larry has an RRS standard alpha for the demonstration. The RRS is grateful to the LAPD CSP program for helping put this together.

We adjourned the meeting at 9:10pm. Next meeting will be July 14, 2017, just before the launch event with Nickerson Projects in Watts that next Saturday, July 22nd.

May 2017 meeting

The RRS monthly meeting was held May 12, 2017. We started at 7:41pm.

The RRS was glad to welcome LAPD Southeast officers Acuna and Terrazas from the Community Safety Partnership (CSP). The nationally recognized CSP program has been very successful in improving community relations in areas of Los Angeles and the RRS is discussing how to bring one of our classes to students in Watts this summer.

We had a few parents stop in the meeting with their kids also interested in working with the RRS and learning more about membership with our society.

The RRS was glad to welcome several new student members from UCLA and a few new full members this month. We had a launch event on April 29th that helped UCLA test several of their technologies in advance of the 2017 IREC competition at the First Annual Spaceport America Cup in New Mexico.

The RRS will hold a launch event at the MTA on June 3rd. UCLA will launch a pair of RRS standard alphas and betas with a few smaller carbon-fiber and fiberglass rockets with 1 lb air-frames and F50 motors. This launch event is the culmination of the undergraduate class, MAE 157A, which is a fluid dynamics and aerodynamics instructional laboratory for the Spring 2017 Quarter at UCLA led by Professor R. Mitchell Spearrin. The RRS is glad to support UCLA in giving university students a place to demonstrate their hands-on knowledge.

Drew Cortopassi of the Aerospace Corporation paid us a visit. Aerospace Corporation is interested in conducting some tests with the RRS at the Mojave Test Area. Once a formal written request is submitted to the RRS, the society will examine the best way to proceed.

For any private organizations wanting to work with the RRS, please contact the RRS, president, Osvaldo Tarditti.

This month, a member managed to acquire a cryogenic LNG tank that would be very useful asset at the MTA. The RRS is working on the logistics for bringing this new acquisition to the MTA for use in future liquid propulsion projects.

The SuperDosa project update will have to wait for next month’s meeting as we ran out of time.

I have been updating the RRS membership roster, but some did not receive the email for the symposium back in mid-April. As people move, sometimes our contact information falls out of date. To all of our membership, please contact me to make sure your email and other contact information is up to date.

Meeting adjourned at 9:11pm. Our next meeting will be June 9th. If there’s anything I missed or needs correction, please let me know.
