DUAL-CHAMBER CONTROLLABLE SOLID PROPELLANT ROCKET MOTOR. VOLUME I - RESEARCH AND DEVELOPMENT EFFORTS

Abstract

The development of propellants for the forward and aft grains was completed by means of laboratory evaluations and subscale motor tests. Present technology was demonstrated by testing full-scale motors containing 300 lb of propellant both at sea-level and altitude. Excellent results were achieved in these tests in which the motors were programmed for both pulse and throttling operation. Thrust ratios as high as 9 to 1 were achieved. Another full-scale test series was conducted to demonstrate the technology advancements made throughout the entire three-year effort. These motors contained the advanced propellants developed during the program, an improved control valve and control system, and nozzles specifically designed for on-off motor operations. Tests of these 300-lb motors were conducted both at sea level and altitude. One of these motors demonstrated nine stop-restart cycles at altitude conditions. A full- scale test that fully demonstrated the feasibility of adapting the DCCSR concept to a post-boost propulsion system was also conducted.
