Micro Thruster Development with Green Propellant at mN and microN levels

Completed Technology Project

Project Introduction

Micro Thruster Development with Green Propellant at mN and microN levels

The objective is to develop a high-efficiency micro-thruster using green propellant with electrospray injector that will ultimately provide micro-satellites with the performance required to enable the replacement of large, expensive, multi-role satellites with inexpensive, short-lead time, distributed systems of micro-satellites.

The objectives of the project is the development of single emitter and multiple emitter injectors for doped kerosene; to develop a fundamental understanding of droplet transport, evaporation, and mixing in the complex swirling flow fields required for meso-scale flame stabilization; and the system integration of meso-scale thrust chamber with electrospray fuel injection system. A single emitter electrospray configuration will be developed and the performance benchmarked using Phase Doppler Particle Analysis to determine the droplet size distribution as a function of flow rate. The nature of droplet transport and evaporation at the meso-scale will be studied using non-intrusive laser based techniques. The electrospray injector will be integrated into the existing heat regenerating thrust chamber and fired with kerosene/H2O2.
