Test Data Reveals Added Security for Future Manned Missions

ELKTON, Md.--(BUSINESS WIRE)-- Orbital ATK (NYSE: OA), a global leader in aerospace and defense technologies, today announced that is has completed analysis of the critical components demonstrated in the Orion Launch Abort System Attitude Control Motor (ACM) test conducted at the companys Elkton, Maryland, facility. Results from the test indicate the motors HT-11 High Thrust test was fully successful.

The ACM consists of a solid propellant gas generator and eight equally-spaced valves capable of providing 7,000 lbs. of thrust in any direction. The HT-11 test used a three-valve version of the ACM to verify the latest design improvements. Orbital ATK recently completed a physical review of all test hardware and an analysis of all test data to confirm that the improvements performed as expected. This key milestone clears the way for the ACM to enter into the qualification phase of the program. Three qualification units will undergo additional static testing in 2018 and 2019, also at Orbital ATKs controllable propulsion center of excellence in Elkton. Founded in 1948, the 550-acre facility employs more than 400 employees, principally engaged in engineering and manufacturing. It is recognized as an AIAA Historic Aerospace Site.

For decades, Orbital ATK has been an important component of Marylands thriving aerospace industry and of Americas accomplishments in space, said Maryland Commerce Secretary Mike Gill. This collaboration between NASA, Lockheed Martin, and Orbital ATK not only illustrates the strength of aerospace in Maryland, but also advances space exploration far beyond our horizon.

The launch abort system (LAS), which is being developed by Lockheed Martin for NASAs Orion spacecraft, will protect the astronaut crew on the launch pad and during ascent. Orion is being built to take humans farther than theyve ever gone before. NASA is building a flexible, reusable and sustainable capability and infrastructure beyond the moon that will last multiple decades and support missions of increasing complexity. Orbital ATK is providing key propulsion subsystems for the LAS, including an advanced ACM to safely control the LAS during the main abort phase and to reposition the capsule for descent and parachute release.
