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.
