The Reaction Research Society held its monthly meeting at the Compton/Woodley Airport location, 7:30 PM PST.

Agenda topics of the meeting were:

  • Symposium successes
  • Restroom operational
  • MTA improvements
  • Wolfram launch 5/20
  • UCLA launch 6/10

Past Events

It is with great pleasure that the Society declares the Symposium to have been a success. In all, there were 22 presenters present, and approximately 70 to 80 persons in attendance. Likewise, Mary Star High School has told us that they did well on their food service sales, and have already penciled us in to host the Symposium at their location again on April 8th, 2024.

However, there is much room for improvement. For example, we need to have better signage for the presentation room and food service at the next symposium. We could also take advantage of the large screens present in the gymnasium to keep attendees up to date on presentations. It was also noted that we should have a hard deadline for speakers to sign up, probably a few days in advance of the event, to prevent scheduling confusion. The older members of the Society are also in agreement that we should hire some of the students to help us setup and break down the Symposium. We could also Mary Star’s WiFi password, and maybe make it available upon request.

The Society was also pleased to receive a donation of eletrical match blanks from long-time RRS member, Steve Majdali. Our treasurer, Larry Hoffing, is to write a receipt for them.

Current Events

Prior to the meeting, Society President Dave Nordling had new keys made for the newly opened MTA restrooms. Six pairs of keys were made, the gold one being to open the restroom proper, and the silver to open the container door to the valves and switches.

In regards to the restroom, it was mentioned that the society should probably hire someone to clean the restroom. In the past, society members have graciously handled cleaning and supplies themselves with the porta-potties, but there is a desire to have the restrooms taken care of by someone else. The main problem seems to be the cost of doing so, and how we might extract compensatory fees from anyone who uses the MTA and doesn’t clean up after themselves. A deposit was suggested, but Frank noted that getting such from a school would likely be a hassle.

Thanks to the Society’s generous donors, we are pleased to announce that a 60-foot launch rail for launching liquid rockets, and prefabbed containers for the MTA, have been funded. Polaris has a design for such a launch rail, and the Society is considering hiring them to build it. Also, in light of the struggles around building numerous projects at the MTA, it is expected that the Society will pay contractors to make improvements to the site mifor the forseeable future.

It’s also been recommended that the Society should have portable launch rails at the MTA. Being portable means that they can be moved away when might be necessary, such as if a group’s view of another launch rail is obstructed. Wolfram in particular has requested 1515 launch rails, but others, such as members of ROC, might appreciate these as well, due to the difference between our height waivers.

Steve Majdali mentioned at the meeting that he has 1,000 ft of duplex wire, 18 gauge solid core, which he might donate to the Society for our use. He also apparently has multi-strand, fine gauge wire, and might even have some sulfur to dispose of as well.

In other news, Society Treasurer Larry has received 3 lbs of 400-mesh zinc powder from a supplier in India. The zinc isn’t of the fineness typically used for micrograin rockets, but Larry will test its use regardless. It should be noted that the zinc was bought at $4 per pound, which is a very good deal, and we might consider sourcing from this supplier in the future. US-based suppliers are not as common today as they have been in decades past.

Future Events

UCLA is currently scheduled to hold their Capstone project launch event at the MTA on June 10th. Likewise, Frank and Larry will simultaeneously be holding launch classes at the site. They will be having two launches, B and C motor model rockets, as well as Baby Bertha.

The Aerospace Corporation is also scheduled to use the MTA for their intern rocket launch event. As of now, there is no conflict on the MTA schedule with their event.

The Society is also receiving more requests for Vice-President Frank to teach more classes. Among past locations requesting his services is Nickerson Gardens.

Also, it has been noted that having underground cable runs between the launch rails and the Garboden Observation Bunker at the MTA would be very valuable. A pull string should be installed along with whatever conduit is put in place, and CAT9 wire should definitely be installed as a good starting point. This facility improvement needs further definition.

The next society meeting will be on June 9th, 2023, at the Compton/Woodley Airport location. Contact the secretary for details.

April 2023 meeting

The Reaction Research Society held its monthly meeting at the Mary Star of the Sea High School, 7:30 PM PST. We went over the agenda quickly as the symposium preparations for the next day were underway.

Agenda topics of the meeting were:

  • Symposium in preparation
    • Model rocket flights at Mary Star High School were not approved
    • Mark Holthaus of FAR confirmed to attend
  • RRS charitable trust status being examined
  • Jim Gross’ eletrical firing video to be hosted over Zoom
    • permission granted for educational purposes
      • DVD will be donated to the RRS
  • RRS invited to LMU’s Engineering Design Showcase
    • Dave plans to attend
  • Pyro-op recommendation letters (Larry)
  • UCLA Capstone and Frank school launch both on June 10 at MTA
  • Bill Claybaugh next launch on Saturday, April 22nd

Current Events

The first topic of discussion at this month’s meeting was that LAFD did not approve the model rocket launch at the RRS Symposium. Paper rockets will be flowninstead.

In addition to this good news, it was also revealed that some additional attendees would be present, in addition to those already known. These include Mark Holthaus of FAR, as well as the Lander Challenge project. Unfortunately, it was also revealed that Northrop Grumman had pulled their attendance from the event.

The topic of the RRS’ charitable trust status was also discussed. It seems that California has changed some annual requirements for renewal. The RRS intends to seek answers regarding the changes. The RRS is a registered 501(c)3 educational nonprofit group in California.

There is some good news for those seeking their pyro-op licenses, though. Jim Gross has announced that he will allow his video watch meeting to be hosted over Zoom. Several members are seeking their Class 2 license and need letters of recommendation for their applications..

Continuing in the vein of pyro-op recommendation letters, some have had questions about the standards that license holders use to write them. The topic has been tabled until the next meeting on May 12th..

In regards to public events, the RRS has been invited to Loyola Marymount University’s Engineering Design Showcase event, set to occur on April 28th. RRS President Dave Nordling is set to attend, but the event is open to the public, so any society member may attend if they are so interested.

Bill Claybaugh has a launch event planned at the MTA next Saturday and it is on track. It is expected that his six-inch diameter solid rocket will reach an altitude of 69,000 feet and be recovered within 5 nautical miles of the launch site, but there are some weather concerns regarding the launch day. It was also mentioned that air traffic control wants to have a single point of contact from all waiver holders. For launches from the RRS MTA, this will be the President.

In additon to Bill’s launch, there is also a UCLA launch planned for June 10th. This is the senior capstone project for this year which will be F and G sized model rockets. Vice-President Frank Miuccio coincidentally also has a model rocket class on location that same day, so the two groups are likely to share the MTA.

The next society meeting will be on May 12th, 2023, at the Compton/Woodley Airport location. Contact the secretary for details.

March 2023 Meeting

The Reaction Research Society held its monthly meeting at the Compton/Woodley Airport location, March 10th, at 7:30 PM PST.

Agenda topics of the meeting were:

  • Jim Gross video watch in San Fernando
  • Symposium
  • MTA Upgrades:
    • MTA Restroom
    • Restroom locks
    • Blockhouse
    • 60 ft launch rail
    • Fencing
    • New generator
  • UCLA 3/2/23
  • Nickerson Gardens, 3/18
  • Claybaugh launch 4/22, 4/29
  • Polaris Propulsion MTA use, August/September
  • Polaris Propulsion meeting, March 14th
  • American Artist
  • FAR solid motor class
  • Expansion of MTA use
  • Plastic bin donations

Past Events

UCLA was scheduled to use the MTA on March 2nd. However, they had to reschedule, and are now due to use the MTA on March 18th. As a part of their use of the MTA, UCLA has agreed to clear some brush on the property on the society’s behalf.

Yet more progress has been made on the MTA restroom project. Though the water pump is not yet running, the shower is operational. Also, Dimitri has been looking into high quality locks for the MTA, having spend $60 so far on the project.

Current Events

Claybaugh is currently working on his next launch at the MTA. As of now, he is scheduled to launch on April 22nd.

As previously mentioned, society member Dimitri is researching high quality locks for the MTA. The ones at the site now are typical residential locks, and have withstood the elements poorly since their installation. The ones Dimitri is currently looking into are better resistant to dust, being used at mines and quarries. The new locks can all be keyed so that the whole facility will only make use of a handful of keys, making keeping a whole set easier.

Jim Gross has also confirmed that his video watch party will be held at his home in San Fernando. Though he is apparently open to hosting future watch parties online, it seems that on this occasion he plans to host the party exclusively in-person. He also is looking into getting an educational allowance from the publisher, for his watch parties.

The RRS symposium is now certainly set to be held at the Mary Star of the Sea High School, in San Pedro, Los Angeles. The society will be arriving early to do necessary preparations for the day, and will likewise do some setup the night before, before or after our monthly meeting, to be held at the same location. Frank has already obtained the keys to the campus, so we will be free to setup before the day of.

In regards to our preparations, it’s been noted that we should seek out Fire Marshall approal for a model rocket, if we are to launch one at the symposium. Mary Star will handle food service for us, and we will need to keep an eye out for vandalism to their campus. We also need to check the quality of their internet service, and to obtain signs and easels.

In regards to attendance of the symposium, a number of groups have confirmed their attendance or absence at this time. FAR has confirmed that they will not be at the symposium. The Air Force might make an attendance, and ROC is expected to come as well. There is also a desire to reach out to Civil Air Control. Over all, it’s been noted that the symposium attendance will have fewer schools, with a greater industry presence.

Society Treasurer Larry has made some progress in regards to the new Blockhouse project. He’s made contact with National Concrete, who can build a new blockhouse, and has received an estimate. This same group has been used by the society previously for the restroom concrete pads.The society has recently accepted the donation of a telescoping tower. The tower is about 50 to 60 feet in length, and the donor is asking for a tax write-off in return.

Headway has also been made in constructing new MTA fencing. Ed’s Fencing has given an estimate of $100k. Their estimate includes a 6-foot high mendable fence, with concrete posts 3 feet in the ground. Alternatives cheaper than this have been proposed, including a simple razor wire fence, by Dimitri.

Another project has also been undertaken for the MTA. Society Secretary Joel has been delegated the responsiblity of improving the MTA’s electrical infrastructure. The current generator used at the site is owned by Polaris Propulsion, and it’s been noted that it is not clean burning. There is a desire to purchase a cleaner and more efficent 20kw generator, as well as to add solar to the electrical infrastructure. It’s been recommended that Osvaldo be contacted in regards to this project.

Frank’s class in Nickerson Gardens is currently set to launch their rockets on March 18th. Frank’s current plan is to launch each rocket three times.

Responses have been received from members regarding FAR’s solid motor class. The class will span over three weeks, and will be led by John Newman. It’s been noted that a single class uses 8 feet of propellant and that a class only takes 4 persons. The classes will be $10 per person per day.

Future Events

Polaris Propulsion is going to make use of the MTA later in the year, starting in August, and ending in September.

American Artist is still planning to launch his rocket. It’s a 1936 vintage Caltech motor, and as of now it is expected to occur either at the end of the year, or some time next year.

The society is also looking into expanding MTA use in the future. There is a desire to hold regular launch events, such as on the fourth Saturday of the month. The society will also need a high power launch rail to accomodate more clients in the future.

The next society meeting will be on April 14th, 2023, at Mary Star of the Sea High School. Contact the secretary for details.
