Propulsion Overview of the Orion Pad Abort 1 (PA-1) Flight-Test Vehicle

The NASA Orion Flight Test Office was tasked with conducting a series of flight tests in several launch abort scenarios to certify that the Orion Launch Abort System is capable of delivering astronauts aboard the Orion Crew Module to a safe environment, away from a failed booster. The first of this series was the Orion Pad Abort 1 Flight-Test Vehicle, which was successfully flown on May 6, 2010 at the White Sands Missile Range in New Mexico. This presentation provides a concise overview of the three propulsive subsystems used on the Pad Abort 1 Flight-Test Vehicle. Although the Constellation program has been cancelled and the operational role of the Orion spacecraft has significantly evolved, lessons learned from Pad Abort 1 could certainly contribute to the vehicle architecture of many future human-rated space launch vehicle
