November 8th 2013 Meeting Report

The November 2013 meeting was attended by 9 members. The date for the next launch is December 7th. The reported balance of the RRS was $17,616. The Society received donations from 3  members. Their names were given but I did not catch them. The road leading to the RRS has been repaired by FAR and Polaris and we will be reimbursing them for some of the cost.

Our membership is now at 64.That number is including the chapter at USC, I had thought that the USC group were members in the RRS directly, but it was explained to me that they are a chapter of the RRS.

 

Osvaldo brought two nozzles from Beta rockets. One was completely steel and had been fired once. There was a good deal or erosion at the throat of the nozzle. The second nozzle, after being fired once, had the throat bored out and replaced with a graphite insert. This nozzle had been fired 2 to 3 times with the graphite insert and showed very little wear especially compared to the standard steel nozzle. It is supposed to be able to last through 5 to 7 firings.

 

The episode of National Geographic’s TV show Meltdown has aired. The show follows 3 people who try to make money by buying precious metal scrap and melt it down to resells it for profit. We watched the part of the show pertaining to rocketry.  Some rocket engines are made with precious metals, for example copper for combustion chambers or silver and platinum in catalyst screens. The RRS was only on for a few minutes and was in a positive light. Hopefully we will be able to share the video with everyone soon. The episode will be reaired at some point and we will pass the info along when we get it.

We had nominations for next year’s executive council were made, and are as follows:

President:
     Osvaldo Tarditti (current president)
     Richard Garcia (that’s me)
Vice President:
     Frank Miuccio
Secretary:
     Chris Lujan
Treasurer:
     Matt Tarditti

 

Nominations are still open for 2 weeks after the meeting and write-ins are allowed. Larry Hoffing will be collecting and counting the ballots.  Details and information on voting should be going out to the administrative members soon. I’ll be sending out a statement for what I plan to as RRS president soon.

 

On the 9th and 10th I attended the 2013 SpaceUp La “unconference.”  That means all the talks, presentations, and sessions are given by the attendees. The time slots and rooms or “Pods” are determined all open at the beginning of the conference and are filled in by attendees on topics they are interested in. Some are presentations and some are open discussions.

 

The event was very interesting. The atmosphere was casual and you got to meet new and interesting people who are interested in space. It was attended by several employees from XCOR and some from SpaceX. Several members from National Space Society where there including some administrative members. Some of the topics at the pods where subluminal inter stellar travel, mechanical counter pressure spacesuits, “Is the Xprize still relevant?”, citizen science, I did a session on 3D printing rocket engines, and there where many more. I gave a T-5 talk on the RRS. The T-5 talks are the main evening event where people give a 5 minute talk with 20 slides.     My talk got a good reception and there is at least one guy who lives near Gardena who may come by our meetings. Hopefully we will be seeing him soon. SpaceUp is something I defiantly recommend for space enthusiast and I’ll defiantly try making it to the next one.

A great surprise to me was that they recorded a section of Planetary Radio on the first evening. I got to talk with Matt Kaplan the host of planetary radio. Matt also works at CSU Long Beach and is familiar with some of the rocketry projects there (who have tested and launched from both FAR and the MTA.) They’ve never done an episode from out at the test site and be he said that they would be interested in it. So we can probably get a spot on the show when and if we wanted.

 

Here are the rockets that are currently planned for the upcoming launch: Chris Lujan plans to test another sugar rocket, this time with a more firmly attached nozzle. Kevin Tice will be launching the Beta he built. And I will have a small sugar rocket to test. If I get everything finished in time I will also be static testing a small propane and oxygen rocket and the H2O2/Gasoline rocket that I’ve been working on.

 

Let’s look forward to a good launch.

RRS featured on National Geographic’s show “Meltdown”

At the last launch [April 27th] we had the pleasure of working with National Geographic for their show “Meltdown.” We’re not sure how much they will show of RRS stuff. Maybe a few minutes. The premise of the show is there is a guy looking to get precious metal from various sources, melt it down and resell it. Some rockets have precious metals like copper for combustion chambers and silver or platinum for catalysts. Sometimes they will have more exotic metals that are expensive metals like niobium or molibduim for radiativly cooled nozzle extensions, but I don’t they went looking for that.

Here is the info:

National Geographic Meltdown segment that was shot at the MTA will air on November 7th at 7:30 PM PST or 10:30pm ET

Here is the link to the show:

October 11th 2013 Meeting Report

The October 2013 meeting was attended by 10 members. The date for the next launched has now been moved to December 7th.I forgot to ask about any updates regarding the condition of the road. It may still be very rough when we get out there. Worst case scenario is having to usesomeone’s 4 wheel drive vehicle to ferry people back and forth who can’t drive the terrain themselves. That would slow us down, but won’t stop the firing. The treasurer reported that the RRS’s current balance is $16865.96. Three members have been promoted to administrative membership: Larry Hoffing, Chris Lujan, and Richard Garcia. Elections are coming up soon. I’m not sure when nominations or voting will be specifically. I think it starts at the next meeting, but I’m not sure. Sorry about the lack of specifics.

John Mariano brought with him some interesting RRS history to the meeting to share. In the 60s The RRS had an interview on TV with Louis Lomax,the first African-American television journalist. John brought some photographs and letters from the event. The story is an interesting one, involving some excitement over wanting to do a static firing in the TV station’s parking lot, and an ad hoc RRS banner.  I couldn’t do the story justice here. I’d like to see it written down for an article in a future RRS newsletter. Obviously that would require rebooting the newsletter, which I would love to do.

 

We are considering having an RRS group tour of the Space Shuttle Endeavor exhibition at the California Science Center. Still on the table is being shown around the USC Rocket Propulsion LAB by the group of RRS members studying there at USC. Since they are near each other we are considering doing them both on the same day in lieu of a typical monthly meeting. Sounds like a great time to me.

Speaking of the USC Rocket Propulsion LAB we have heard the results of their attempted suborbital space shot. The Traveler rocket blew up around 20,000 ft. But still, it’s an accomplishment to get as far as they did and to even be able to say they tried it. I hope they can comeback from this and give it another try.

We discussed some launches and testing that we may be doing in December. Of particular interest was the discussion of Jim Gross’s planed static test of micrograin rockets motors. Although he expressed that it probably won’t be ready for this next firing. He intends to take some high quality data on the pressure curve of a micrograin rocket. There has been some long standing questions about how this propellant burns and he hopes to shed some light on the issue. Preparing this test is particularly challenging because of the need for some high temperature strain gauges whose application requires a specific heat treatment regiment for the high temperature adhesive that may need to go up to 600⁰ F. Does anyone have access to a heat treating oven? I was thinking that I could help make a programmable autoclave but that might be excessive for a one time use. But if there were some people who also need one for composites, or other heat treating, it might be a good excuse for making an RRS autoclave. Anyone interested? Either way Jims test promises to be interesting.

 

I’ve talked with Frank and Osvaldo and we will soon be working together to finish the web site. I’ll need them to setup a PayPal to take payments and to give me member information so I can set up a database of members so everyone who has already paid or is a lifetime member will have access to the members section of the web site.
