Design and Performance Evaluation of Components of Micro Solid Propellant Thruster

Research on micro solid propellant thruster is presented. Micro solid propellant thruster has been attracted attention as a one of possible solutions for micro satellite thrusters. Micro thruster as a system has four basic components. It is composed of micro combustion chamber, micro nozzle, solid propellant and micro igniter. In this paper, as a part of development of micro thruster, fabrication and test of micro igniter, combustion characteristics of solid propellant in micro chamber and fabrication of prototype micro thruster and ignition test are described.
