ENVIRONMENTAL CONTROL AND LIFE SUPPORT SYSTEMS (ECLSS)
OVERVIEW
Human access to space continues to evolve beyond the International Space Station, with new missions to the Moon, NASA’s Lunar Gateway, and commercial space stations. Whenever humans are involved, environmental control and life support systems (ECLSS) must be in place to maintain a habitable breathing atmosphere and thermal environment. Moog has been producing hardware in support of NASA’s Orion Crew Module, specifically used in the cabin pressurization system and thermal control system. This hardware leverages Moog’s capabilities developing space-qualified valves to control gas and liquid media. Hardware covers the gas supply and distribution systems, along with the thermal control system.
FLUID TRANSFER COUPLING
The Moog Fluid Transfer Coupling (FTC) Is a stainless steel, two piece design using passive and active halves to secure fluid connection and sealing. Connection of the two halves will open the flow path after the sealing engagement is established. The design can be supplied with or without a locking mechanism and has an allowance for misalignment.
QUICK DISCONNECTS
High pressure quick disconnects facilitate installation of LRUs that support removal and replacement of system components, including replenishment of gas storage tanks.
REGULATORS
Motorized isolation valves allow remote actuation to control the flow of breathing gases to the system, feeding into pressure regulators that safely drop the high pressure stored gas to levels that support distribution into the crew environment.
LOW PRESSURE FLOW CONTROL AND ISOLATION VALVES
Moog’s low pressure ECLSS components include motorized, solenoid, and torque motoractuated valves to manage the distribution of breathing gas to the crew.
HIGH PRESSURE FLOW CONTROL AND ISOLATION VALVES
Moog’s nitrogen and oxygen ECLSS components manage the supply of high-pressure gas for atmosphere control. Manual valves connected to tanks provide safe, controlled access to breathing gases.
