Orion Multi-Purpose Crew Vehicle
On December 5, 2014 the Orion Multi-Purpose Crew Vehicle (MPCV) Exploration Flight Test-1 (EFT-1) took its maiden flight on a Delta IV launch vehicle. The purpose of the EFT-1 was to provide data about systems critical to crew safety, and to validate designs of the spacecraft before it begins carrying humans to new destinations in deep space. NASA’s Orion MPCV spacecraft is built to take humans farther than they’ve ever gone before. Orion will serve as the exploration vehicle that will carry the crew to space, provide emergency abort capability, sustain the crew during the space travel, and provide safe re-entry from deep space return velocities. Orion will launch on NASA’s new heavy-lift rocket, the Space Launch System.
Valve Control System (VCS)
Orion will fly with an active Attitude Control Module (ACM) on its Launch Abort System (LAS). Moog will provide the Valve Control System (VCS) for ACM. The VCS consists of a redundant electromechanical actuation system that controls direction of the abort system and the crew module. Actuators and control electronics will be used for the position control of the eight hot gas pintle valves.
Pressurization and Propulsion Systems
Twelve thruster valves support the reaction control system (RCS) of the Crew Module (CM) on the spacecraft used during re-entry to orient the vehicle for landing. Moog also supplies hardware to the pressurization system, including the High Pressure Isolation and Crossover Valves (HPIV and HPCOV) and the Low Pressure Isolation and Crossover Valves (LPIV and LPCOV), each containing isolation valves and a stepper motor actuator.
Environmental Control and Life Support Systems (ECLSS)
The Active Thermal Control Subsystem (ATCS) built by UTC Aerospace Systems provides cooling of the vehicle avionics boxes through a pumping system and ammonia boiler/tankage to provide additional cooling post-service module separation through post-landing. Moog supplies the CM with ATCS valves, including solenoid valves which regulate ammonia to the boiler and torque motor valves that control flow to the coolant system and service module.
Vibration and Shock Mitigation
The Orion Crew Module is subject to extreme vibration and shock environments through its accent via the SLS launcher. Moog is providing engineering expertise in vibration and shock mitigation to reduce these loads on different systems of the crew module. This system will be designed and manufactured specifically for this mission and implemented on the vehicle.
