A system for controlling solid propellant gas generators including a microcessor which has inputs such as the sensed temperature of the gases in the solid propellant gas generator, the pressure within the solid propellant gas generator and/or pre-programmed input control signals to the microprocessor for causing the microprocessor to produce signals that are used to control a modulation valve which in turn controls a thrust nozzle device that controls exhaust gases from the solid propellant gas generator.

Active control of solid propellant generators using throat modulation

Apparatus for modulating the thrust vector of a rocket motor by injecting t gas into the divergent section of the rocket nozzle and modulating injection of the hot gas by varying the flow from a solid propellant gas generator by controlling its flow rate with a vortex throttling valve arrangement.

Gaseous secondary injection thrust vector control device

An angular rate sensor is conceived which operates by utilizing electrica conducting fluid flowing in a transverse magnetic field. The electric field induced in the flow direction due to rotation will produce a signal that is proportional to angular rate.

Angular rate sensor

Aerodynamic surfaces are fixedly mounted in the diverging section of a rot nozzle and a fluid is injected through the fixed jet vane to flow about the vane. Fluid flow is controlled to make it appear that from upstream the jet vane is at an angle of attack. This deflects the main flow and produces side force. A minimum of injection flow enables high side forces to be obtained for missile control.
