Motor Notes

Cert notes John Coker May 25, 2010

These motors are called Tribrids, specifically for their ability to use both a nitrous oxide oxidizer, solid ABS grains, and now certified for the first time, liquid alcohol as fuels.

The K600TR-P is a 70% K motor, a slightly longer and different (larger bore) injector version of the K350TR-P motor. It has 2170 total NS, 1223 NS max, a 561 N average and a 3.67 second burn time. The thrust profile is again a typical hybrid profile, the initial rise to about 170 pounds for about .1 seconds, then a transition to the Tribrid phase (alcohol introduction) for a second rise to 250 pounds. From there it is straight line regressive to the 2.2 second point and 150 pounds, where it enters vapor phase, dropping to 50 pounds. It then does a typical hybrid tail-off to zero at the 4.6 second point. The motor total weight (pre nitrous) is 6.55 pounds with 370 ml alcohol (.82 lbs.), .21 lbs ABS grain weight, and 1476 cc of nitrous oxide capacity. Post weight is 5.52 lbs.
