PROJECT TITLE :

Silicon-on-insulator-based microsolid propellant thruster array

ABSTRACT:

A silicon-on-insulator (SOI)-based microelectromechanical system solid propellant thruster array is presented. The micronozzle layer and microigniter layer of the array are formed on each surfaces of the SOI wafer, respectively. The layout design rules will properly distribute the warmth made by the microigniter below the solid propellant within the chamber. Check results show that the best temperature of the microigniter is found under the propellant. When one unit in the array is ignited by a DC voltage of seven.nine V, other units around it aren't ignited. Moreover, the ignition resistors can work once more, which means that the array can be used repeatedly when the solid propellant is refilled.
