Propulsion Systems and Subsystems

Subsystems supplied by Moog connect critical parts of a propulsion system. Subsystems support chemical, electric and cold gas propulsion systems.



Electric and Cold Gas Propulsion Systems

Moog provides many electric propulsion system components that can be integrated into subsystems as to control propellant flow to the thrusters, overall feed system control and regulation, or a combination of both often called: Common 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, 702 XIPS, 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.

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.
