The first RATTworks Tribrid motors have been certified by Tripoli
As seen on Rocketry Planet, it appears that Tripoli Motor Testing (TMT) has certified two RATTworks Tribrids: a 1861K350TR-P (45% K) and a 2170K600TR-P (70% K motor). For those who don't know what a Tribrid is, it a hybrid hybrid/liquid motor (at least I think the latter describes it). That is, they use Nitrous Oxide as an oxidizer and both solid ABS grains and liquid Alcohol as fuels. RATTworks has been working on them for some time and IIRC they have flown at TRA Research events. This is cool but is sure to result in discussions regarding safety and fire codes. It will also to see if the NAR accepts this certification.
