Technology Demonstration Missions
Solar Electric Propulsion (SEP)
Project Introduction
Mission planning for infusion in the ARRM mission with key technology developments including: - Design, develop, and test a high-power, 12.5 kW Hall Effect thruster. - Design, develop, and test a high-power (120-to-800V) processing unit (PPU) using innovative silicon carbide circuits to overcome the challenges of high power PPU design, and thereby enable the development of future high power electric propulsion systems. - Mature flexible membrane solar array designs to be ready for flight development. - Demonstrate full, integrated performance of 120-to-800V PPU with 12.5-kW Hall Effect thruster strings powered by electricity from multiple 20+kW class flexible solar array wings.
