Propellant Feed Systems

Physical Infrastructure

Propellant Feed System

The MON-X feed system supports MON-3/MON-25/NTO volumes up to 500 mL, pressurized up to 2500 by a piston system. The Monopropellant feed system is also piston fed, with propellant volumes up to 82 mL at 1500 psi. The H2O2 feed system is nitrogen pressurized and contains up to 1 L propellant volume at 1800 psi. The gaseous oxygen (GOX) feed system can support pressures up to 2400 psi. The Bipropellant feed system can hold 17 L propellant at 6000 psi. Any jet on jet fuel and oxidizer combination (down to -20° C) can maintain pulsed or continuous operations via piston system.
