Advanced Green Micropropulsion System

Systima in collaboration with University of Washington is developing a high performance injection system for advanced green monopropellant AF-M315E micropropulsion systems (0.1 – 1.0 N) for small- and micro-satellites and cubesats (100 kg-500 kg and <100 kg). The monopropellant has low-toxicity making it easy to store, integrate into modular designs and launch without added costs associated with handling toxic propellants such as hydrazine. The injector is a critical component that is designed to enhance combustion and optimize microthruster performance. In the Phase I program, Systima and UW completed proof-of-concept tests that demonstrated the injector technical concept and system advantages. In the Phase II program we will develop a prototype injector design, conduct injector performance testing and workhorse microthruster hot-fire tests with AF-M315E. This effort will result in a monopropellant injection system for modular microthruster system designs that meets the needs of current and future small- and micro-satellites for NASA missions, commercial and military customers.
