Solid Rocket Booster Command Destruct System Hazard Study,
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 grains/foot HMX with an aluminum liner to 1000 grains/foot 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 case/propellant. 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 Sensitivity/Denotability 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.
