Moog Plays a Key Role for the Future of Spaceflight: Orion Exploration Flight Test-1

5 December 2014

Moog Inc. (NYSE: MOG.A and MOG.B) Space and Defense Group provided mission critical hardware to Lockheed Martin and UTC Aerospace Systems for Orion’s Exploration Flight Test-1 (EFT-1) that took place today from Cape Canaveral, Florida. EFT-1 will provide engineers with data about systems critical to crew safety, and will validate designs of the spacecraft before it begins carrying humans to new destinations in deep space.

On future missions, the Orion spacecraft will transport astronauts beyond low Earth orbit (LEO) to deep space and return them safely home. It will provide emergency abort capability, sustain the crew during space travel and provide safe re-entry from deep space return velocities.

The first Orion spacecraft was integrated with the Delta IV Heavy rocket built and operated by United Launch Alliance (ULA). Moog supports ULA on the first and second stages of this launch vehicle. On the first stage Moog provides three pogo suppression valves, one on each core of the vehicle, the valves function to suppress oscillations in the ducts carrying liquid oxygen to the rocket engines. On the second stage, a Moog Electromechanical (EM) Thrust Vector Control (TVC) System plays a key role supporting attitude control after separation of the first stage. In addition, Moog provided the Inlet Valves for the Aerojet Rocketdyne RL10 main upper stage engine and the Control Valves for the Aerojet Rocketdyne Roll Control Module (RCM) Thrusters.

Moog also delivers flight-proven, critical hardware to the Lockheed Martin built crew module (CM) portion of Orion. Twelve thruster valves support the reaction control system (RCS) on the spacecraft used during re-entry to orient the vehicle for landing. Moog also delivers 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.

In addition, Moog supplies the valves for the Active Thermal Control Subsystem (ATCS), which is built by UTC Aerospace Systems. The ATCS 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.

For flights beyond EFT-1, 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.

The uncrewed EFT-1 flight will take Orion to an altitude of approximately 3,600 miles above the Earth’s surface, more than 15 times farther than the International Space Station’s orbital position. By flying Orion out to those distances, NASA will be able to see how Orion performs in and returns from deep space journeys. Moog is excited to be an integral part of spaceflight for the future.
