BALLISTIC SCALE-UP NF PROPELLANTS. IV. EVALUATION OF NF PROPELLANTS IN A 6-INCH MOTOR.

Abstract

Twelve 6 X 18-inch Application Motors were cast from a single 300-lbm batch of RH-SE-103af propellant and used to evaluate the capabilities of NF propellants under tactical environments. Motors were fired at -35F, +77F and +135F to establish baselines for comparisons with those subjected to temperature extremes. Motors were fired successfully at -35F after 30 days at -35F, at +135F after 34 days at +135F, at +77F after 3, 5, and 7 cycles between +135F and -35F, and at +77F after 30 cycles between +135F and +77F. No defects of any kind were found in visual and radiographic inspections of the motors, and no aberrations in the pressure- and thrust-time curves were observed. Two motors are in ambient-temperature storage in an Army igloo; one will be fired after one year and the other will remain in storage indefinitely.
