Abstract:

Alcor 1B, solid-propellant rocket motor was successfully tested at an average simulated altitude of 100,000 ft while spinning about its axial centerline at an average spin rate of 304.3 rpm. The objective of this test was to evaluate the ballistic performance, tailoff characteristics, and structural integrity of the flightweight motor assembly under the combined effects of rotational spin and near-vacuum environment. The vacuum total impulse was 256, 616 lbf-sec the vacuum specific impulse, based on the vacuum total impulse and pre- and post-fire weight difference, was 279.12 lbf-seclbm. The total burn time, defined as the time interval from the application of voltage to the igniter to the time when the chamber pressure-to-cell pressure ratio is 1.3, was 35.30 sec.
