Just as an FYI, I checked the rules for the BALLS launch regarding the
use of a kerosene - nitrous oxide rocket motor after our discussion on
"...Liquid Engines MUST request written approval from the Tripoli
Board of Directors."
They don't say they are illegal, but rather hint that there is
probably a lengthy process to getting them approved. I thought I had
read that before, but there it is.
From the Tripoli site:
Tripoli Research Safety Code
5.2. Liquid Rocket Motors
With the exception of nitrous-oxide hybrid rocket motors, liquid
rocket motors are prohibited at Tripoli Research Launches. BOD
approval may be given for very well documented liquid motor projects.
We may get in by doing a well engineered and tested design.
Considering the the ISP is better than hybrids, and it easily lends
itself to vectored thrust as a sustainer engine, I may look into this
some time next year.
