Abstract:
Trends and optimum conditions of mass fraction, boost-velocity, and motor envelope with variations in motor performance parameters and propellant characteristics for the dual-chamber controllable solid propellant rocket motor concept were studied. Five independent variables motor performance parameters and propellant characteristics were selected for this study 1 total impulse, 2 minimum thrust, 3 thrust throttling range, 4 number of on-off cycles available, and 5 motor specific impulse. The first four variables define the capability of a throttleable stop-restart motor, and each directly affects mass fraction, boost velocity, and motor envelope. The fifth variable, which is a function of propellant composition, directly affects motor size and boost velocity,
