Evaluation of the Thiokol TE-M-640 Solid-Propellant Rocket Motor Under the Combined Effects of Simulated Altitude and Rotational Spin

Abstract

Three Thiokol, Inc., TE-M-640 solid-propellant rocket motors were tested at average pressure altitudes of 100,000 ft, 111,000 ft, and 105,000 ft, respectively, while spinning about their axial centerlines at 180 rpm. Test objectives were to evaluate altitude ballistic performance and lateral (nonaxial) force and to demonstrate structural integrity of the motor case and nozzle. The first two motors failed 27 and 8 sec, respectively, after ignition. After modifications to the motor manufacturing procedures, the third motor was tested and performed satisfactorily. Test results for the three motors are presented and discussed herein.
