The Effects of an Immiscible Binder Component on the Rheological and Mechanical Properties of a Composite Solid Propellant,

摘要

The Improved HAWK antiaircraft missile is powered by the M112 rocket motor. This motor operates in boost and sustain modes derived from concentric booster and sustainer composite solid propellant grains (Figure 1). The booster propellant is relatively fast burning to provide the thrust level necessary to accelerate the missile to intercept velocity, while the sustainer propellant burns slowly over a much longer time to maintain missile velocity and maneuverability during the mission. The booster grain is fully bonded to the sustainer grain which in turn is fully bonded to the steel motor case by means of an adhesive case liner.
