EVALUATION OF PROPELLANT DEFECTS USING TRANSPARENT ROCKET MOTORS
Abstract
A transparent motor tube loaded with solid propellant has proved useful as a tool for studying problems of motor operation. Forty transparent motors were fired in a test program for the purpose of evaluating improper case bonding, cracked grains, and igniter operation. Conditions under which side burning occurs in improperly casebonded motors were determined, and the rate of side burning in 2- and 5-inch motors was calculated. The ignition process and the performance of an igniter were observed, using a transparent half-motor. High-speed film records of side burning and cracked-grain burning were obtained, and 100-pps binary-coded timing (BCT) was used to obtain accurate correlation of pressure, thrust, and film records.
