# Test 2017-12 # 5 grain 75mm sorbitol motor with pyrodex pellet ignition in 4-inch Wildman rebuilt airframe at NCR North. Trimmed CTI 5-grain case (25.75" overall), Loki #42 nozzle, CTI aft closure ring, forward bulkhead from Terry's pile machined to have 0.5" inside snap ring plus 0.25" inside liner, with two o-rings, one pushing against liner. Liner 23.125" long with about 22.25" available for fuel load. Simulation says this is a 57% L-1366 with 3804 Ns total impulse, 797 psi max, 76% volume loading, and about 2.6 seconds burn time.
