Past Events

Another update which we were pleased to announce is that the President of the society has been formally admitted to the CALFIRE subcommittee on Fireworks, under which rocketry is governed, and which will be rewriting the existing regulations.

The Compton Comet project also had its first low pressure test earlier this month. There were many leaks, but the team is now nearing the point that they will need to carry on their testing at the Mojave Test Area (MTA).

A new member to the society, Abdullah Daya, also asked if there was any certificate available for those members who attended the society welding class in Vista. It was decided that the society would ask the instructors at a later time.

Current Events

The society is pleased to announce that member, Wolfram Blume, is currently seeking his pyro-op license. He currently only plans to obtain a Class 3 Rockets license, but the society currently seeks to expand its license holder count which will ease the planning of future MTA events requiring the presence of the same.

There was also a fairly lengthy discussion regarding society owned tools. Society member Mohammed Daya researched welding helmets on behalf of the society, giving a recommendation for a particular brand out of a few. There was also a recommendation for individuals to use prescription lenses, and helmets with small viewports should be used to prevent ones vision from wandering.

There was also discussion of a new requirement that individuals using society equipment sign waivers to reduce our liability, similar to the waiver required for MTA use.

Unfortunately, due to the recent weather in California, the launch event on January 14th for a project by American Artist has been cancelled. Dave still wishes to meet with him at another time, and hopefully schedule another date for his project at the MTA.

Another unfortunate situation has occurred, in that the FAA has reduced ROC’s height waiver by a substantial amount (7,000 feet). This will make the larger high-power launches impossible from their Lucerne Valley location. However, it was suggested that the society could reach out to ROC, and offer them use of the RRS MTA for their launch events. Keith Yoerg said he’d reach out to start a conversation.

In regards to the RRS MTA site improvements, the creation of more launch rails therefore was discussed. Materials for the construction of the same have been bought, and their design was briefly debated, with radio towers being mentioned as a frequent base. It was also mentioned that CAD software would be useful in our construction of any of the larger rail designs. A 60-foot launch rail for liquid-fuelled rockets is a top priority at the society this year.

An update on USPS protocols has been announced, that all mail addressed to a PO box must now also give the street address of the Post Office it is located at. Any such mail without an address will be returned to sender, so mail to the society should have the address written as such.

An unexpected but minor blow to the society’s fundraising was delivered recently when Amazon announced that the AmazonSmile program will be discontinued in February this year. The money earned by the society therefrom was not a vast sum, but per our treasurer, Larry Hoffing, the loss of this small revenue stream means that pizza parties will be cancelled indefinitely. The society has yet to hold one of these events but the loss will still be felt.

Future Events

Starting on Sunday the 22nd, we are planning to have a multi-day work event at the MTA. This will do work on lighting and other electrical work on the site. Handicap rails and an access ramp also need to be installed soon. Dimitri will be present, and other volunteers are encouraged to participate as well.

On January 28th, there is another planned launch event for those wanting training in micrograin loading amoxil and launching. Jim Gross will be the pyro-op in charge.

Also on the same day, FAR will be holding a liquid rocket symposium at the Flabob Airport in Riverside. The RRS has been invited, but due to the limited gathering size only a couple individuals from the society will attend.

This April, Bill Claybaugh is planning to launch from the MTA. Likewise, the RRS symposium is planned to take place some time in April. Frank is currently in contact with the Gardena Community Center to see if we can hold the event there again this year on our 80th anniversary.

In regards to the symposium, there is currently no set budget, but it has been suggested that some of the society’s generous benefactors might be contacted to help cover costs.

Jim is currently in possession of zinc that might be used for sulfur micrograin. Some, contained in pales, are known to be good, but some received by mail are of unknown condition. It’s expected that the latter will be tested order phentermine soon so as to determine its use.

Next meeting will be February 10th. Contact the secretary for details.

80th Anniversary of the Reaction Research Society

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.

October 2022 meeting

Posted on by

by Dave Nordling, President, RRS.ORG

The society met at the Compton Airport front office again for our monthly meeting on October 14th. Mike LaGrange joined us by teleconference for the first time. Joel Cool-Panama was welcomed as our newest administrative member.

We first reviewed past events,

  • USC RPL sample grain burns
  • pad anchor modifications
  • restroom progress at the 10/1/22 work event

We spoke of pending events

  • Bill Claybaugh’s new pad, 10/20-10/22
  • Aerospace Corp launch of experimental motor, 10/20
  • next work event, 11/5-11/6, more plumbing
  • USC RPL static fire on 11/12
  • Events subject to change, public calendar soon to come online with the new website

The RRS reported quarterly dividend from Smile.amazon.com

Further concrete repair work is needed. Four of the 28 mounting holes need more work. This will likely be done by the society. We need to determine best way to extract old anchors and patch the holes with sufficient time for curing before redrilling. USC RPL will assist by drilling final anchors once repair work is done. USC has been very helpful in making this important site improvement.

A budget update on restroom with expenses to date and how much to finish. Last estimate showed we’re on target. An update is coming before next month. Our goal is for the restroom to become operational by year’s end.

The society is working hard to help other members to become pyro-ops. More pyro-ops means safer operations and greater flexibility in future events. Frank and Bill Inman have their letters and are working on their applications. The best way to start is being active with society events and apprenticing under experienced and licensed individuals.

RRS has updated their flight waiver with the FAA to 100,000 feet. Some planning and advance notice required. Laminated copy of our waiver and instructions will be put in the Dosa Bldg. Also, launch requirements available from the RRS president.

Patrick Finley of the Collegiate Propulsive Lander Challenge attended. He explained his foundation to encourage propulsive landing technologies among university groups. Five technology prizes. The RRS is a supporter of this initiative. He can be reached at “patrick@landerchallenge.space”

Wolfram Blume has been working on the Gas Guzzler over the summer. Fuel pump and flameholder fixes. Next flight could be in December?

Bill Inman is building the 2nd generation Solar Cat with fellow member Dale Talcott in Nevada. Subscale prototype built in the summer had excellent focus and heating. Next test at MTA could be December, perhaps January.

John Krell’s avionics chips have had some improvements. Now can do 16 channels at over 1 kHz all on a chip fitting in a slim alpha payload tube

First meeting with LACMA by the president and VP on a STEAM project focused on the arts. Further discussions will better define the RRS role. 

2023 Symposium will celebrate our 80th anniversary, tentative date is April 8. Researching locations, food service and potential speakers. Official launch will be in the new year.

New launch rail design proposed for high power rockets using 24-feet of 1515 launch rail and a 1-ton hand-winch to operate. It will be an outdoor fixed asset and supplement existing launch rails. Need to get a materials list and drawings made for a contractor quote.

Larger 60-foot launch rail for liquid rockets is in the planning stages. The RRS has had several entities interested in using such an asset.

We will soon be starting the effort to sort out the old equipment in the north yard, determine the purpose, origin, and dispose or refurbish each item. We must use our space wisely and not store articles without a relevant purpose. Junk will always fill a void.

RRS may be getting a new pair of storage containers and fire-fighting equipment. Council is in discussions and supportive of this site improvement. More details later.

Some at the meeting indicated strong interest in learning how to weld. The RRS is seeking an instructor which may give us training for a nominal fee. More on this next month.

3D printers were discussed near the end of the meeting. Several members have the devices, but design tools are just as important. Google Sketchup, Solidworks and CATIA are options but costs on some can be prohibitive. This would make a fine topic for a future article on RRS.ORG

Nominations for executive council offices will be at the November meeting next month. An election chairman will be appointed who is neither a current office holder or a candidate for office.

Next meeting at Compton Airport front office on 11/11/2022 at 7:30pm.
