80th Anniversary of the Reaction Research Society

by Dave Nordling, President, RRS.ORG


Today, January 6, 2023 marks the 80th anniversary of the Reaction Research Society.

Founded in 1943 by George James, this small club of young boys gathered in Glendale to study and conduct experiments in reaction propulsion. It all began with a child’s chemistry set that included zinc and sulfur powder as a demonstration of exothermic reactions. This would lead to rockets and newer propellants and ever increasingly complicated experiments in the remote northern areas of Los Angeles from Mint Canyon to Rosamond to our present location east of Koehn Dry Lake. Many members of the Reaction Research Society have pursued professional aerospace careers making important contributions to the field.

In the war years of the 1940’s, rocketry was more the subject of science fiction and speculation than the robust science it is today in the early 21st century. Our society has seen eight decades of growth as a collective group of enthusiasts and colleagues supporting research and offering shared testing spaces while remaining dedicated to responsible projects and scientific progress. It is with pride that we share this milestone with the public on a bold new year of launch, facility improvement and looking forward to the future.

Our month meetings are held at 7:30pm on the second Friday of each month by teleconference and in person at the front office of the Compton/Woodley Airport on Alondra Blvd. in Compton. For details, contact the RRS secretary.

MTA Firing Event, 2022-11-12

by Jim Gross, Reaction Research Society


The RRS hosted the University of Southern California (USC) Rocket Propulsion Laboratory (RPL) from Friday, 11/11, to Sunday, 11/13/2022 for a static firing of their latest experimental class, solid propellant motor design, Firebiter. I was the pyrotechnic operator in charge with Keith Yoerg and Michael Rouleau apprenticing.

USC firing campaign logos keep getting better and better

Back in September, USC completed a series of test grain burns which gave valuable regression factors necessary for their full 6-inch scale solid motor.

Borrowing from painful past experiences, USC RPL under their team leader, Julia Woomer, found a good compromise between stability and performance as evidenced by their hotfire on Sunday just three minutes before noon.

USC RPL demonstrated a good motor at the RRS Mojave Test Area

The RRS has had a long successful relationship with USC for over a decade. USC will prepare another full-scale motor for flight soon.


November 2022 meeting

by Frank Miuccio, Vice President, RRS.ORG


The Reaction Research Society held its monthly meeting November 11, 2022, at 730pm, at the front office of the Compton/Woodley Airport. Others were able to join us by teleconference.

Agenda topics for the meeting were:

  1. Review of recent MTA/rocket events:
  2. Upcoming MTA events including bathroom work & USC static fire on 11/12/22
  3. 1-day welding class in Oceanside – who is interested?
  4. CALFIRE fee increases
  5. 2023 executive council nominations

Recent MTA/rocket events were reviewed including the November 5th work event on the restroom.

RRS has purchased a 20-foot high cube container that will be placec next to the new bathroom container which will be our new fire station which will house fire suppression equipment. It was suggested that we paint the container red or at least part of it red. The RRS also purchased a 35 GPM water pump with 1” hose and adapters and spray nozzles. An all-terrain vehicle for firefighting has been on our bucket list for awhile. We discussed current fire suppression tools including the pressurized water type fire extinguishers and shovels. It was recommended we do a fire training class at the MTA yearly so people know how to use the current and future solutions. We will need a volunteer to coordinate this effort.

Upcoming MTA events include the static fire event with USC RPL from Friday 11/11/2022 and into Saturday 11/12/2022. USC’s latest 6-inch vehicle, Firebiter, will be tested before committing to launch their next flight article later this year.

Bathroom work continues. There are a few items that still need to be installed such as some plumbing and connections to the infrastructure.

The RRS has found a skilled private individual, Jay Miller (and son), willing to teach a one-day welding class. The cost will be substantial but split among those who will attend. It is not common to find this kind of training on a weekend. Jay will have 3 rigs to divide among the students at their shop in Oceanside, CA. Metal welding samples of aluminum, carbon and stainless steels with filler material and plates to weld on will be provided as well as gases.

Carpooling is recommended once a firm date is set. People with interest need to confirm very soon.

CALFIRE is opening a public comment sessions for proposed fee increases which affecting our operations.

Pyrotechnic operator annual license fees for Rockets Classes 1, 2 and 3 from $50 to $100

Public Display licenses will increase from $200 to $350 annually.

RRS members will attend this meeting with CALFIRE in December. The RRS will produce a joint statement representing the society’s opposition to fee increases. It is unlikely we will be successful in dissuading the state fire marshal from increasing fees.

This topic also went to discussing the process to become a pyrotechnic operator and encouraged more people to begin the application process to become licensed. Frank said he will update people as he goes through the process. The hardest part is securing five letter of recommendation from licensed pyro-ops. After letters are ready, applicants need to be fingerprinted at Live Scan locations in California.

Cameron Kurtz spoke to the RRS about a solid motor project he was working on (he is in Texas). He was looking if anyone had data that he could use. John Krell and Michael Rouleau will be working with Cameron offline

2023 executive council nominations were held as we do at each November meeting. RRS member, Drew Cortopassi, was appointed as our election chairman. Drew will be sending out ballots to the administrative members and must receive them back before the December meeting. Nominees are listed below. All offices are running unopposed.

Secretary = Joel Cool-Panama

Treasurer = Larry Hoffing

Vice-President = Frank Miuccio

President = Dave Nording

Straw rockets and air rockets were discussed. They are very simple and popular tools used in our educational programs. Frank showed the launchers used for the classes to launch them. Frank also showed examples of straw rockets and air rockets.

On straw rockets, the process of the nose cones was discussed. First phase starts with molded clay. Second phase was foam ear plugs. Third phase was rubber end caps (bolt caps cover). This latest version has improved the launch. Frank also discussed what students learn from the activities.

Next meeting will be December 9, 2022. Meetings are always held on the 2nd Friday of each month.
