Project DAME - Tactical Instrumented Missile Simulation Testing

Abstract

Results of a previous program -- an instrumented modified 14-inch bomb dummy unit (BDU) flown on an F-111 aircraft -- were applied, analytically, to an AIM-7E (Sparrow) motor. An inert Sparrow motor was instrumented with accelerometers, strain and stress gages, and thermocouples. It was then subjected to thermal, dynamic, and captive-flight simulation tests that cover the expected range of loadings to be encountered in captive flight on high-performance aircraft. Random vibration input control was based on BDU response during actual captive flight, which compared favorably with MIL-STD-810C requirements at frequencies below 400 Hertz. An enhanced spectral input based on assumed response on aircraft such as an F-4 was also run. Both analysis and experiment indicate that stresses imposed on the motor from thermal changes are relatively low. Propellant characterization and aging data and gage calibration data are presented. Calibration data presented are sufficient to permit data reduction from actual captive-flight tests.
