The RRS was glad to host an event at the Mojave Test Area for the UCLA Rocketry Club. This group of two dozen students launched a series of G-sized model rockets for their rocket building event on July 10, 2019.
Each of the rockets had an egg as its payload. All but one was recovered intact. Each rocket had a custom data logging package including a barometer as an altimeter and an accelerometer. Average altitude was 2,480 feet with a group average peak acceleration of 14 G’s and thrust of 25 lbf.
One concern some of our members had from last week was if any of the structures at the MTA suffered any damage from the recent pair of earthquakes at Ridgecrest only a little more than 30 miles away across the dry lake desert floor. The RRS is happy to report that the damage seems minimal in that both the old block house is still standing and the George Dosa Building doesn’t look any worse for wear.
The RRS was glad to support this student event with UCLA. There will be a second, similar rocket building program later this month. For questions about future events, contact Larry Hoffing

On Saturday, June 1, the Reaction Research Society (RRS) hosted the UCLA Aerospace Engineering senior design (MAE 157A) class at the Mojave Test Area (MTA) I have been teaching this class for three years which involves the design, analysis, manufacturing, testing, and finally launch of mid-power solid and hybrid rockets. Approximately 50 students attended this event at the end of the Spring Quarter of 2019 with RRS president, Osvaldo Tarditti, serving as pyro-op.
Twelve rockets were fabricated by students teams of four or five students each over a 9-week period, eleven of which were launched successfully on Saturday. The launches included nine solid composite rockets in the E and F-size classes. Two of the rocket designs involved a staged design, with retro-exhaust ignition for the second stage.
Two hybrid rockets using polyvinyl chloride as fuel and nitrous oxide as oxidizer were launched on the RRS 20-foot 1515 rail launcher. The hybrids were fully fabricated by students at UCLA including the propulsion systems. All rockets included payloads of altimeters, cameras, and a hard-boiled egg with the design competition aiming for altitude and reusability upon recovery.
With the assistance of Osvaldo’s ATV, all rockets were successfully recovered, though only a few were returned with an unbroken egg.

The Reaction Research Society (RRS.ORG) is glad to be a part of an upcoming event with Spaceport L.A. The “Rocket Workshop with the RRS” is an excellent opportunity for anyone who wants to get directly acquainted with rocketry. This event is meant for both professionals and non-professionals alike. From younger students to university students of all fields, to adults, this event is meant to give people the experience of assembling and flying your own rocket.
The event will begin on Saturday, May 4, 2019 with a subsequent launch of the rockets from the RRS Mojave Test Area (MTA) on Saturday, May 18, 2019. At this event, you can learn about the fundamentals and more practical knowledge of rocketry.
The event will be held at the HexLab MakerSpace in Van Nuys. This is laser-cutting service in the Los Angeles area. Check the Spaceport L.A. website for the details and updates.
The RRS standard alpha rocket is a very old, but reliable design still used in the society. Although micrograin propellant is not used anywhere else but at the RRS (where it was initially discovered in the 1940’s), it is a simple and powerful propellant combination that makes for an impressive show of raw power. I have attached an earlier description of the RRS standard alpha rocket below.
After the first session, on the second event, you can go out to the RRS’s private Mojave Test Area (MTA) at Koehn Dry Lake, east of Cantil, California in the high desert. The RRS will handle the propellants, you can see the impressive results from the safety of our observation bunker.
Amateur rocketry is our passion and purpose and the society is glad to hold this event with Spaceport L.A. and the public.
