EFFECT OF AERODYNAMIC-HEATING SIMULATION ON MARK 24 SIDEWINDER 1C SUSTAINER GRAINS
Abstract
Sidewinder 1C sustainer grains were given aerodynamic-heating cycles to determine damaging effects on the propellant and its peripheral inhibitor. Propellant grains were heated in a thin-walled motor tube having a nichrome- ribbon heating element on its outer surface. Ethyl cellulose inhibitor on the propellant grain proved to be most susceptible to degradation. Cracks in the inhibitor and large unbonded areas developed after 5 to 10 mission cycles. A mission cycle consisted of increasing the skin temperature from 130 to 250 F in 3 min, remaining at 250 F for 12 min, rising from 250 to 275 F in 2 min, then remaining at 275 F for 3 min followed by cooling to 130 F.
