Commercial Feed System for Spacecraft Applications (New Space)

Moog has a modular single string and redundant commercial feed system that is ideal for spacecraft applications requiring electric propulsion. The system is able to regulate high pressure from a tank downstream into a thruster assembly for multiple propellant types, including Xenon and Krypton. System can be tuned for multiple different pressures and outlet ranges.
