Long Life, Catalytic Advanced Green Monopropellant Thrusters, Phase I

Completed Technology Project

Project Introduction

Sienna Technologies, Inc, proposes to develop a robust, long life, catalytically ignited thruster that can perform multiple cold starts at low preheat temperatures (<<425˚C) using high performance green AF-M315E monopropellant that can provide a range of mission specific thrust levels for NASA SMD's sample return missions. In Phase I we will improve upon Sienna's industry leading SSC-111 catalyst and demonstrate its multiple cold start capability at low preheat temperatures (well below state-of-the-art 425˚C) in sea-level laboratory tests.
