BALLISTIC SCALE-UP OF NF PROPELLANTS. II. EVALUATION OF NF PROPELLANTS IN A 6-INCH MOTOR (INTERIM REPORT),

Abstract

Ballistic and mechanical properties of a representative NF propellant (RH-SE-103) are being evaluated in a 6-inch motor designed to have many of the characteristics required for a tactical application. A coned-cylindrical grain geometry was substituted for the original slotted-tube configuration on the basis of improved specific-impulse efficiency and low-temperature capability. The coned-cylindrical geometry was fired successfully at temperatures of -31 F, +77 F, and +135 F. The temperature coefficient was 0.13%/ F, exactly the same as had been measured in 2 x 4 motors. Specific impulse efficiency was 97% in both the 6CC18 and 6C5-11.4 motors. Six-inch motors containing RH-P-112 were used to evaluate grain designs, to investigate the effect of grain design on specific-impulse efficiency, and to check analytical stress-strain predictions in low-temperature firings.
