Paul Breed asked me to check out a couple things about the course for the 2013 Sparkfun AVC. So I went to check it out. Here’s the ground course video:. The course generally slopes upward from the start line to the third corner, then slopes back down to the fourth corner. There’s also a gallery of photos on Flickr.

I wanted to show the difference in FEA between loading the easy way, into faces of the single part, vs. a more accurate way, into a simulated bolt and loadcell button. The scales are the same in both sets of images. The latter set shows that applying the force through a button and 0.24″ rod signifi...And finally...

Randy's Rocketry: October 2014

http://randysrocketry.blogspot.com/2014_10_01_archive.html

Friday, October 24, 2014. Propellant testing (Dextrose, Sorbitol, Erythritol). KNER (erythritol based propellant). That test cato'd half way through the burn. I do still want to redo that test, but this time with a stepped core. After that test I reduced the segments to 6 and it was successfully flown. I plan to fire this motor as a 4 segment and as a 6 segment motor, with some luck I may get the 8 segment motor ready as well. Saturday, October 18, 2014. Subscribe to: Posts (Atom).

Thursday, February 28, 2013. SStS, CSD UPDATE. Chamber Separation Disk (CSD) in the Mid-Bulkhead. I completed the modifications to the MBH ,CSD, and plug recently. The entire DSS TM-1-2 test motor is now with another project member undergoing hydrostatic testing. There seems to be a lot of mixed feelings about this approach, I'm just hoping it works. Hopefully the testing goes well and we can get to a test firing soon. Subscribe to: Posts (Atom). SStS, CSD UPDATE. Rocketry and related sites.
