Abstract:

A new case material, filament wound graphite, will be utilized on certain launches. The Linear Shaped Charge LSC of the destruct system has also been changed from 750 grainsfoot HMX with an aluminum liner to 1000 grainsfoot HMX with a copper liner. Because of these changes, NASA requested the Naval Surface Weapons Center NWSC to determine experimentally the effects of the Command Destruct LSC on the SRB casepropellant. This paper will summarize the various work elements and their specific findings. The LSC activation tests did not produce a detonation of the propellant on any of the tests. The most severe reaction studies indicated that the formation of a porous bed was highly unlikely. The Shock SensitivityDenotability Studies indicated that direct shock initiation of detonation by the LSC is impossible. They indicated that a Deflagration-to-Detonation Transition DDT would not occur.
