ABSTRACT

A functional micro-electromechanical system (MEMS)-based micro-thruster using boron–potassium nitrate pyrotechnic composition with an electron beam deposited platinum heater has been characterized for reproducible ignition and sustained combustion. Configuration of the device, assembly process, and the energetic material were selected based on a detailed study involving a series of ignition tests. Successful ignition was achieved for the chosen configuration and the energetic material. The development demonstrated potential of such devices along with scalability for futuristic applications aimed toward downsizing of micro-spacecraft propulsion systems.
