Abstract
A gas generator or rocket motor is provided in which discrete and accurate time vs. flow output relationships or profiles are established by the rotation of a rotor located between the exit and its combustion chamber to various positions to select one of a plurality of primary nozzles or orifices of accurately calibrated predetermined flow characteristics through which pressurized gases from the combustion chamber are directed by passages in the rotor. The gases then flow out of the device through an exit comprising nozzles in the case of a rocket motor.
