Propulsion Systems and Subsystems
Electric and Cold Gas Propulsion Systems
Moog offers several electric propulsion system components that can be integrated into subsystems to control propellant pressure and or flow. Common subsystem names include: Propellant Management Assembly (PMA), Xenon Flow Controller (XFC), Proportional Xenon Feed System (PXFS), Xenon Control Assembly (XCA), Flow Control Unit (FCU), and Proportional Xenon Flow Assembly (PXFA) depending on the customer.
Missions: AEHF, Deep Space-1, DAWN, Plegpay, GOCE, BepiColombo, SmallGEO (SGEO), LS1300, TacSat-2
Pressure Management Assembly
The Pressure Management Assembly (PMA) is a single fault tolerant, parallel redundant branch regulation assembly that stabilizes and controls xenon inlet pressure to a downstream, low pressure flow control device.
Flow Control Unit (FCU)
Moog has a modular single string and redundant solenoid feed system that is ideal for spacecraft applications requiring electric propulsion.
Pressure Regulation Assembly (PRA)
The 50-1451 Pressure Regulation Assembly (PRA) is a fully welded stainless steel assembly consisting of two proportional flow control valves (PFCVs) in parallel, and one high pressure and two low pressure transducers.
Xenon Flow Controller (XFC)
The 50-1412 high pressure Xenon Flow Controller (XFC) is a fully welded stainless steel assembly consisting of three components (Flow Control Valve – FCV, Proportional Flow Control Valve – PFCV, Latch Valve – LV) and three orifices mounted to a flight plate. Two different flow rate split ratios between anode and cathode are possible with this design.
Chemical Propulsion Systems
Propulsion systems are used for satellite and missile attitude control applications. Moog engineers specialize in rapid development and have built one-of-a-kind monopropellant and dual mode systems for upper stages and target vehicles. Areas of expertise include thermal and structural system analysis, flow analysis, dynamic testing of propellant loaded systems and system hot fire at altitude.
Missions: Galileo (ENSS), ORBCOMM Generation 2 (OG2), Landsat 8 (LDCM), Fermi (GLAST), PRISMA, multiple missile defense applications.
