Abstract

This paper reports an orthogonal analysis method for decoupling on structural parameters of microthrusters. Geometrical parameters that impact the performance of microthruster are sorted by range analysis, which is first used to explore how to fully decouple structural parameters. The results show that the throat width affects the thrust seriously. Although the average specific impulse (ASI) decreases at the beginning and then increases when increasing half convergence angle and throat radius of curvature, both of them have less influence on the ASI than exit-to-throat section ratio and half divergence angle as a whole. A MEMS solid propellant thruster (MSPT) was carried out to prove its feasibility.
