December 2020 virtual meeting

By the Reaction Research Society


The Reaction Research Society held its last monthly meeting of this difficult and eventful year 2020 on Friday, the 11th. The teleconference was well attended and included some students from Loyola Marymount University. We began the meeting with the treasurer’s report and moved to the first order of business.

Our meetings by teleconference will continue into the new year.

ELECTION RESULTS FOR 2021 EXECUTIVE COUNCIL

The results of the election were presented by this year’s appointed election chairman, Dave Nordling. The full slate of nominees were elected from the nominations at the November meeting.

President = Osvaldo Tarditti

Vice President = Frank Miuccio

Secretary = Keith Yoerg

Treasurer = Larry Hoffing

The society thanks our outgoing secretary and treasurer, Drew Cortopassi and Chris Lujan respectively, for their service in this year, 2020. We welcome our new executive council members as they start their annual term on January 1, 2021

We appreciate the many voting members who responded this year. The society was sad to learn of the passing of two of our lifetime members, Thomas McGaffey and Mike Gottlieb.

ANNUAL MEMBERSHIP DUES

The RRS treasurer reminds our society membership that annual dues are to be paid on January 1st of each year. This is a continuation of RRS policy set forth by the executive council in 2019. In year 2021, membership dues have increased for student membership while full membership dues remain the same. As always, student membership in the RRS is valid all year regardless of how many events we hold.

Full membership = $40 USD / year

Student membership = $30 USD / year

Annual membership dues are an important source of revenue to support the society’s operational costs. Associate, administrative, student and corresponding members are required to have their dues be fully paid to maintain active membership status.

For questions regarding dues payments, contact the RRS treasurer:

treasurer@rrs.org

There are two common means of dues payment:

(1) Click the “Donate” button on the RRS website which links to Paypal. This is the easiest method for the society to receive and confirm payment. When using this method of payment, please make a note that you are paying ‘annual dues’ and the name of the person it is for. The Paypal website gives you the option to share your address with the society, Please do so as this marks who the payment is from. Contact the RRS treasurer if you have questions.

(2) Payment by check can be submitted to our post office box in Los Angeles. As the executive council checks the post office box only periodically, it may take some time for your payment to register. With all mailed correspondence, please email or call the RRS treasurer to let them know it is coming.

When making your dues payment, it is also important to update your contact information with the RRS treasurer. It is the responsibility of the RRS treasurer to maintain the membership roster and record payment of membership dues. It is the sole responsibility of every member, past and present, to keep their email and other contact information up to date with the society.

NEW PYROTECHNIC OPERATOR LICENSING

Keith Yoerg announced he has made significant progress in his application to becoming a licensed pyrotechnic operator. The RRS has been supportive of increasing our roster of pyro-op’s. Keith is one of several RRS members in this process. The RRS and the Friends of Amateur Rocketry organization have been working with CALFIRE since last year on improving definitions for state regulations on amateur rocketry in California. Our two organizations have been supportive of each other’s members’ desire for training and instruction in the course of becoming licensed pyro-op’s. It is to our mutual benefit to have more people knowledgeable about safe operations in our hobby.

SITE IMPROVEMENTS AT THE MTA

The RRS continues to evaluate its options for an improved restroom facility at the MTA. The council has put this as the top concern and is in the process of evaluating bids. The society would like to proceed with a replacement during this winter season. More storage space, replacing the roof on the old blockhouse and finding a towable fire-wagon with a water pump are also on our list of improvements.

MTA LAUNCH EVENT

The RRS has a scheduled launch event on December 12th. Dave Nordling will be the pyro-op in charge for this event. Three launches are planned including Wolfram Blume’s first systems flight test of his two-stage Gas Guzzler ramjet and Dave Nordling’s and Larry Hoffing’s 3-inch rocket with an improved nitrous oxide hybrid motor. Bill Inman also plans to be at the MTA to test his third design iteration of his solar collector which will now include his launch rail and his new SimpleCat 2-inch steam rocket.

LOYOLA MARS TEAM PRESENTATION

The society was happy to welcome upperclassmen students from Loyola Marymount University to our December meeting teleconference. Loyola MARS is a recurring senior capstone project to incrementally design, build, test and fly liquid rockets leading to a final design capable of reaching the von Karman line in under 10 years. It is an ambitious project that was inspired by the former Base11 competition. The RRS has supported the Loyola MARS team since its start and was impressed by their initial systems design. The society looks forward to supporting their first fluid systems tests and static hot-firing at the MTA in the coming new year.

As an educational non-profit group, the RRS provides assistance to several local universities who are building rockets for class projects. We welcome student groups to indicate their interest in attending our meetings by contacting the RRS executive council.

IN CLOSING

2020 Constitutional Committee is overdue in presenting the new draft and policy statements to our active membership for review. This will be delivered at next month’s meeting by the appointed committee. Once our membership has had the chance to offer it’s feedback and suggestions, the new Constitution will be sent to our voting membership for ratification.

The RRS treasurer’s report on membership status will also be deferred to next month’s meeting.

The RRS wishes everyone to be safe in this holiday season and take appropriate precautions in this COVID-19 pandemic.

The next monthly meeting will be on Friday, January 8, 2021.


November 2020 virtual meeting

by the Reaction Research Society


The RRS held its monthly meeting on November 13th. The teleconference brought several of us together again from different parts of the city and around the country.

PAST EVENTS

The society discussed the prior launch event at the MTA held on November 7, 2020. Details of the event are in the firing report posted this month. More RRS members are buidling more rockets and this is a good trend, We were not able to work on site improvements at the event, but these tasks can be resumed at the next event.

The 2020 Constitution Committee is almost ready to release the recommended draft with updated policy listings according to RRS vice-president Frank Miuccio who is the single executive council representative on the committee. Release of the draft will go out in December 2020. If ratified by the voting membership, this new Constitution will clarify RRS rules and policies and supersede all past revisions.

FACILITY UPGRADES AT THE MOJAVE TEST AREA

The society discussed the current progress of facility upgrades approved by the executive council. At the top of the list is a new restroom facility. A couple contractor bids are forthcoming with one being delivered just a few hours before the meeting. Cost is an important consideration and other designs besides a block and concrete design are being considered. Containerized, portable systems may offer an effective solution with fewer complications.

The council approved the construction of a similar pit toilet like the one being used now at the MTA. The second toilet is meant to replace the first as it will not be usable for much longer. A few RRS members are already working to put in this stop-gap measure until the better facility can be selected and funded.

Second pit toilet at the MTA approved as stop-gap measure.

Other site upgrades discussed at the meeting was replacement of the roof structure on the existing blockhouse which would be a temporary but safer solution until a new structure can br funded and built. Another was removal and replacement of the bent panel on the vertical thrust stand which may be done at the next launch event. Still another improvement option is purchasing some of the existing containers from our tenant for more storage space at the site and a water storage tank.

Other improvements include locked and secured areas for high-pressure gas bottles and cryogenic liquid cylindeers. Towable water-spraying trailers have also been discussed to augment fire-fighting at the MTA. A larger launch rail system for heavier liquid rockets at the RRS MTA is also being considered.

NOMINATIONS FOR EXECUTIVE COUNCIL

As per the Constitution, the society holds nominations at the November monthly meeting for the four elected executive council positions. Terms will start in the new calendar year, First, an election chairman is appointed by the council. This person can not run for office in that election cycle. Dave Nordling was selected as election chairman.

Only administrative members in active status can be nominated and hold office. The nominees will be listed on the ballots going out to the eligible voting membership. Ballots will be sent by email which underscores the importance of all members keeping their contact information up to date with the RRS treasurer. Also, one of the requirements of active membership is being current with dues payments also tracked by the RRS treasurer.

October 2020 virtual meeting

by the Reaction Research Society


The RRS held it’s monthly meeting by teleconference on October 9th at our usual starting time of 7:30pm. We had a few members calling in from out-of-state. We had a few new topics to cover.

Some of the attendees to the October 2020 monthly meeting

SUMMARY OF RECENT MTA EVENT

We held a work event at the Mojave Test Area on October 3rd which was very successful despite higher temperatures for that autumn Saturday. We cleared a lot of tumbleweeds, mended the barbed wire fence at our front gate, painted the metal window gratings on the front of the Dosa Building and even cleared off the decks of the large vertical test stand. We had a lot of great help and we hope to continue making these site improvements to make our facility more attractive and useful.

We agreed to meet at the MTA again on November 7th which will coincide with a static fire test of USC’s Rocket Propulsion Lab latest multi-grain solid motor design. We will also attempt to remove and replace a bent panel on the vertical thrust stand. The nitrous oxide hybrid rocket by Dave Nordling, Larry Hoffing and Osvaldo Tarditti is also ready for launching. If there are other member projects that are ready we will add those to the event and notify the pyro-op in charge.

LIQUID ROCKET PROJECTS

Liquid rocket projects have become more popular recently and some have started within the RRS.

Loyola-Marymount University (LMU) in Marina del Rey started a capstone project for their upper classmen in their undergraduate aerospace engineering program to design and build a large liquid rocket. The LMU Lion project was inspired by the FAR-MARS competition. Dave Nordling has been supporting the early design work on behalf of the RRS starting early this calendar year prior to the pandemic restrictions ending in-person meetings. LMU has restarted the project with the new academic year with a series of specialized coursework and short presentations on topics from experts around the industry. Dave was glad to present the history and capabilities of the RRS. The presentation was well received and LMU has looked at using our vertical test stand when they get their first liquid rockets systems ready for test.

Loyola Marymount Aerospace Research Society

The Compton Comet project at Tomorrow’s Aeronautical Museum has been restarted with RRS members, Waldo Stakes, Kent Schwitkis and Dave Nordling. The Compton Comet is a liquid rocket to be built, tested and flown at the RRS. It is a larger vehicle design which has several parts built and will use a surplus XLR11 single-chamber fueled by LOX and a 75% ethanol-water blend, It is a very ambitious project for the Compton College STEM students but it will provide an excellent means of learning practical skills.

UCLA is continuing Project Ares for this next academic year. Last year’s liquid rocket vehicle design was in its final preparations for a Spring 2020 launch at FAR until the pandemic closed campuses around the country including the UCLA Lab. UCLA invited a few RRS members to attend their preliminary design review by teleconference. They are proceeding with several design improvements from last year’s vehicle design and when their laboratory access is restored under carefully regulated conditions, they hope to have another static fire at the RRS and flight from FAR next spring.

Thr Rocket Project at UCLA

Richard Garcia had started a design for a small liquid fueled rocket that would be easier to build and serve as the basis for a common or standard design for society members wanting to test and fly a liquid rocket at reasonable cost. Propellants are ethanol and liquid oxygen. The design has features proven from past successful liquid motor testing at the RRS MTA. The first prototype of the small 125 lbf motor is in build now. After successful demonstrations of the motor in hot-fire, the vehicle will be built.

There is a rocket hangar space opening up at the Compton/Woodley Airport which RRS members will soon have access. It has been a goal to have a work space within the city centrally located for most of our members. Operations at the rocket hangar will be limited to construction activities and small-scale pressure tests and cold flow operations, but it will offer our members a greater convenience for those with limited working space in their homes. Contact Wilbur Owens and Xavier Marshall for details. Social distancing and mask protocols would apply.

MTA FIREFIGHTING MEASURES

Fires are one of the greatest risks that come with amateur rocketry. At the behest of several members we have been discussing way of better preparing to fight fires from our site. The roughly one dozen pressurized water containers we have in our storage container are filled and made ready at every event. These have been useful for containing any fires starting at the pads. The RRS is looking at storing large quantities of water at the MTA. We’re also looking at trailer mounted water tanks that could be pulled by a small all-terrain vehicle (ATV) with a motorized pump spray system. These are commonly found in agricultural locations and would be an excellent addition to help limit the propagation of downrange fires until county resources can arrive.

MTA FACILITY UPGRADES

New restroom facility designs have been discussed over this summer. Concepts have been discussed with contractors and firm cost proposals are being prepared. Issues like cost and permits are important concerns. The society last year approved this facility upgrade project as the top priority.
