A solid propellant rocket motor of gas generator of the type having retractable filaments embedded in the propellant for the purpose of controlling the overall thrust or mass flow output is combined with a channeled separator located between the propellant and its casing with the channels open to the combustion chamber. This results in distribution of combustion chamber pressure and temperatures over the exterior of the propellant grain so that distortion of the grain will not occur sufficiently to cause binding or sticking of the filament in their holes...
A rocket motor or gas generator comprising in combination, a casing including a combustion chamber, a solid propellant grain mounted in said casing, a separator between said grain and the casing, a head closing one end of said casing, at least one opening at the opposite end of said casing, filaments embedded in said propellant, means adapted to retract the filaments during burning of the propellant at various rates to vary its overall burning rate, the separator including walls defining at least one channel in its surface adjacent the casing and port me...
