PERFORMANCE OF A UTC FW-4S SOLID-PROPELLANT ROCKET MOTOR UNDER THE COMBINED EFFECTSOF SIMULATED ALTITUDE AND ROTATIONAL SPIN

摘要

One United Technology Center FW-4S solid-propellant rocket motor was fired at an average simulated altitude of 103,000 ft while spinning about its axial centerline at 180 rpm. The objectives of the test program were to determine motor altitude ballistic performance including the measurement of the nonaxial thrust vector and to demonstrate structural integrity of the motor case and nozzle. These objectives are presented and discussed.
