One Thiokol Chemical Corporation TE-M-521-5 solid-propellant apogee rocket motor was successfully fired at an average simulated altitude of about 108,000 ft while spinning at 46 rpm. The primary program objectives were to determine vacuum ballistic performance of the motor which was temperature conditioned at 40F, determine altitude ignition characteristics, evaluate motor structural integrity, and determine motor-spacecraft temperature-time history during and after motor operation. Additional objectives were to measure the lateral nonaxial thrust component during motor operation and to measure radiation heat flux in the vicinity of the nozzle exit plane. Author
