Abstract


The paper deals with study of the concept and design of the solid propellant Divert and attitude control (DACS) system. The Solid Propellant Divert and Attitude Control systems, which provides pitch, yaw and roll control and divert propulsion for the kill vehicle maneuvering, these thrusters uses variable throat are through Valve controls to modulate the thrust & also thrust vectoring. The four divert thrusters provide short/ long pulses to quickly and accurately position the interceptors. The critically of the solid propellant motor design and the thrust modulation using the throat area have been studied. Design has been carried for the hardware of motor, the valves, and the nozzle throats. The design involves selection of materials for motor, divert thrusters and the igniter. Initial ballistics performance predication has been carried out for propellant grain design to meet the requirement for the thrust modulations and the continuous attitude control system.
