Abstract:

The technical features of the bipropellant miniature divert thrusters developed in this institute were briefly described.It is well known that this type of thrusters should meet the requirements of light weight,fast response and small minimum impulse when used for terminal guidance of space vehicles.To achieve this,new design concepts and technical approaches were applied in present thrusters,including bipropellant torque motor solenoid valve,platelet injector,C/C thruster chamber,and welded joint between metallic and non metallic materials,etc.As a result,a series of test firings were successfully implemented with the thrusters.
