Abstract
As a fallout of the development program which was carried out by the Army Advanced Ballistic Missile Defense Agency, (currently the Ballistic Missile Defense Advanced Technology Center), for a pintle-regulated controllable interceptor motor, two test motors were developed which were used to comparatively evaluate different thrust vector control systems and propellant extinguishment under different conditions of motor free volume and under different thrust levels. A total of five motors were fired under this effort. This paper will discuss the various aspects of these motors. This will consist of such topics as motor designs and design changes; motor processing; some of the motor fabrication problems; multiple ignition system; and test results.
