Aging and Surveillance Testing of a Minuteman LGM-30F Stage II Rocket Motor at Simulated Pressure Altitude (Motor S/N AA20078, Designation OP-15)
Abstract
LGM-30F Stage II solid-propellant rocket motor, designated OP-15, was fired on December 12, 1972, in Rocket Development Test Cell (J-5), Engine Test Facility (ETF), in support of the operational phase of the Minuteman Aging and Surveillance test program. The objective of this test was to determine any degradation in performance or decrease in reliability that may have occurred as a result of 7.3 years of operational deployment. Motor ballistic performance was within specification. The motor was ignited at a pressure altitude of 98,000 ft. Motor ignition delay time was 109 msec. Motor action time was 65.82 sec, during which the motor produced an unaugmented vacuum total impulse of 3,951,955 lbf- sec. The unaugmented vacuum specific impulse was 287.61 lbf-sec/lbm. Average chamber pressure during motor action time was 456 psia. The liquid-injection thrust vector control and roll control systems operated satisfactorily throughout the firing. Postfire motor structural integrity was satisfactory. Data are presented showing the performance of this motor as compared to the performance of other LGM-30F Stage II motors tested at AEDC.
