ABSTRACT:
An energy efficient solid propellant attitude control system for use on post boost vehicles equipped with post boost control systems, post boost propulsion systems, and velocity control systems utilizes gas from a gas generator to drive a gas turbine which drives an alternator to produce electrical power. The turbine effluent gas is selectively directed to highly vectorable hinged nozzles to provide attitude control for the post boost vehicle. Power from the alternator is used to drive electromechanical actuators which orient the highly vectorable hinged nozzles. The turbine effluent gas is also selectively directed to fixed thrusters and twin axial thrust motors.
