Lots of progress with RRS archiving and history

Posted on by

We’ve had a lot of progress recently with archiving RRS newsletters and other publications. I’ve put up six more newsletters. I’ve posted three more newsletters I received from Osvaldo a while back and had backlogged to post. This includes issue Vol_54_4_Dec_1997.pdf which is the second half of the RRS’s summary of the history of liquid propellant work at our getting prednisone society.

Three more editions of the early Astrojet newsletter where also posted in the newsletters section with the help of Dave Nordling who got Caltech’s JPL library to send us what digital copies they had of Astrojet. I suspect they may have more in their archives because it seems odd to have only three non-sequential issues, but we haven’t been able to locate them through their catalog. The RRS is thankful to the Caltech JPL library for retaining and helping us obtain a copy of these early works of the Glendale Rocket Society (former name of the RRS). We hope to work with them more in finding all we can on the RRS history.

Dave Crisalli shared with us ten more articles and two videos. These reports and videos have been posted on the “Other RRS articles” tab of the RRS website.

Six of these articles are from High Power Rocketry Magazine and were authored by Dave. Also included was the most recent versions of David Elliot’s and Lee Rosenthal’s hydrogen peroxide (H2O2) monopropellant rocket report from the 1950’s.

Dave Crisalli’s package included a Scientific American magazine article from 1957 which includes mention of the RRS. This is on the “Articles about the RRS” tab of our website.

Also we have an improved version of Dave Crisalli’s 1976 liquid rocket report that has been updated with more pictures and drawings.

Dave also shared two fantastic videos. One is the video report on the hydrogen peroxide (H2O2) monopropellant rocket that was filmed at the time of construction and test in the 1950’s with audio narration by David Elliot being added later by Dave Crisalli.

The second is a video report on Dave’s sounding rocket, a written report on the Rocket was also shared. This video also includes some liquid propellant work done at the time by other RRS members.

Both of these new videos can be seen on the RRS YouTube channel linked below. Please subscribe to our channel so you can be informed of updates as we make them. There will certainly be more to come!

Frank Miuccio, our society VP, contributed a small collection that I’ve also posted to the “articles about the RRS” tab of the RRS website. This included six magazine articles and some news clippings.

Another item added to the other RRS articles section, brought to us by John Mariano and scanned by RRS secretary, Dave Nordling, is a short book on early micrograin rockets jointly from the Reaction Research Society (RRS) and the Pacific Rocket Society (PRS). The title is simply “Micrograin Rockets” and was written by B.J. Humphreys Jr with excellent illustrations and descriptions.

Dave Nordling is also working on scanning a second book from John Mariano’s personal library which should be available soon.

A lot more will be coming soon. Frank Miuccio managed to obtain a collection of RRS newsletters. They are issue numbers 59 through 100 and he has lent them to me to scan. This will double the number of newsletters we have archived!

In addition to that, Dave Nordling has gotten for us the RRS material that happened to be scanned and collected by the Google Books Library Project. This was five documents some with several Astrojet editions included. The collection totals 934 pages in all. Although some of the Astrojet newsletters are duplicates. The collection includes reprints of the first eight RRS newsletters from our founding in 1943! A truly impressive find which we hope to share soon.

All this new material will have to be scanned and parsed before being posted, which I hope to accomplish one at a time over the next few months. I’ll write a follow-up post once it’s all up on the RRS website.

More RRS newsletters

We strongly encourage our current and former membership to consider donating or just letting the RRS borrow articles, photos and reports for scanning and inclusion into the ever-expanding RRS archives. We hope to build a great story for the RRS history project coinciding with our upcoming 75th anniversary next year.

If there are any errors, clarifications, questions, suggestions or other things you’d like to add or donate to the RRS archives, contact me at research@rrs.org.

June 2017 meeting

Posted on by

The monthly meeting of the RRS was held June 9, 2017, at the Ken Nakaoka Community Center in Gardena. The meeting was called to order at 7:45pm.

The launch event with UCLA was successful. We accomplished a lot with many different groups present. Again, we thank Dave Crisalli for being our pyro-op for the event. The RRS discussed the event and how we could manage these events in a more orderly fashion.

Several steps for improvement were discussed including tighter control of incoming vehicles and setting our operating procedure into written form for publication. In the future, the RRS should require all attendees to the MTA send their indemnification forms well in advance of the event so we know how many people we are expecting. Also, we need to use a full 10 second count instead of the 5 second count which will allow more time for the spotter to stop the launch if a problem is detected. An earlier draft of the RRS operational safety codes exists and was approved. The RRS secretary will circulate a new draft to the executive council before the next meeting on July 14th.

Minor facility improvements were discussed including how to mitigate the stifling heat at our desert site. Frank was willing to buy a water-fed misting fan that might help some people inside the Dosa building or perhaps inside the bunker. If the device works well, the RRS may consider buying a second unit to help create a small cooling space for those who are most affected by the heat.

I sat in my truck’s air conditioning a few times that afternoon as wearing the fireproof suit for the micrograin loading operations only added to my mounting heat exhaustion. Dave Crisalli had mentioned there are vests that hold flat ice packs that can be worn inside of protective suits. This will buy some time to work more comfortably under hot conditions.

Hydration, sunscreen and proper clothing for the desert heat are always important to all individuals to protect themselves both before and during the events held at the RRS MTA. The Mojave Desert is a tough place. It’s this attention to these details that are key parts of everyone having a successful event. As we do operate year-round through the hot months, there will always be this hazard to manage.

We reviewed the video shot from the launches. It has been suspected that the existing micrograin launch rails are a little too short resulting in the rockets leaving less than straight from the rails. We discussed newer longer rail launchers. It was decided to try to recover an old rail system that is already at the MTA as a backup.

Frank brought several old paper copies of the RRS newsletters. Some of these date back to the early 1950’s and others were from the 1960’s. The RRS is actively working to electronically archive as much of these newsletters as part of our on-going RRS history project.

RRS News, Issues 98 and 101

Issue 101 mentions a story where the RRS was on the old Louis Lomax show which was a local semi-weekly news program in Los Angeles from 1964-1968. John Mariano and George Dosa were there and we hope to someday find the archival footage and post this to our YouTube channel. (I think it was Issue 101? Someone correct me if I am mistaken.)

The RRS has in fact set the date for the upcoming 75th anniversary symposium which will be April 14, 2018. We will have it at the Ken Nakaoka Community Center as before. We have already begun the process of contacting speakers and exhibitors. We hope to make this event even better than this last year.

John Mariano brought his rocket on a string. This is a classic demonstration of the fundamental principle of propulsion using a CO2 cartridge guided on a plastic clothesline. The rocket was easily able to traverse the full length of the Ken Nakaoka Community Center ballroom, even uphill to the stage where Larry was holding the stop. Bill and I took video of the event and its on the RRS YouTube channel. Link is below:

After some false starts in getting the spring loaded puncturing device to work, we got it to work. Simple, but very fun! This demonstration of the fundamental principle of jet propulsion is a favorite in our educational events.

The RRS is looking forward to doing an educational event with the students of Nickerson Projects in Watts. After the teaching sessions, the launch event is scheduled for July 22nd. Larry has an RRS standard alpha for the demonstration. The RRS is grateful to the LAPD CSP program for helping put this together.

We adjourned the meeting at 9:10pm. Next meeting will be July 14, 2017, just before the launch event with Nickerson Projects in Watts that next Saturday, July 22nd.
