San Diego Rocket Society 2003. Two launches in a Month! On December 21, 2017. On November 18, 2017. A couple screen grabs during ignition from a test earlier this year. Another load in the 76-7600N-s hardware set that cranked out 8760N-s. On February 12, 2016. Perfect flying conditions this past weekend, full report here. On January 27, 2016.

Monday, February 2, 2015. Theo and I stopped by the F-1 rocket engine display outside of the Aerojet Rocketdyne facility in Chatsworth, CA yesterday. You can find more info on this engine display by clicking here. Friday, January 16, 2015. Thursday, January 15, 2015.

CAD modeling and analysis for Sugar Shot to Space. Calvin and Hobbes on engineering design. Least accurate, but easiest, is using empirical models. Rockets and planes have been flown supersonic many times, and from that dataset researchers have created simple equations that can crudely predict the temperature and heating that will be seen in flight. Is the recovery temperature, in Kelvin or Rankine.
