GenCorp (NYSE: GY) company Aerojet Rocketdyne said it recently completed its final J-2X test series at NASA´s Marshall Space Flight Center.
Over a period of three years, Aerojet Rocketdyne teams manufactured, assembled and tested four newly developed engine test articles that achieved an accumulated duration of nearly five hours firing time and demonstrated full power operation for twice its designed life service. Delivering 30 percent more thrust and five percent more performance than the J-2 Apollo-era engine, upon which it is based, the J-2X is the highest performing human-rated upper-stage engine to be developed in nearly 40 years.
The J-2X is a liquid-oxygen/liquid-hydrogen fueled engine that is designed to start at altitude and re-start in space as part of a second or third stage of a large, multi-stage launch vehicle. With its full nozzle extension installed, the J-2X measures more than 15 feet tall and 10 feet in diameter at its base and weighs approximately 5,400 pounds. With a vacuum thrust of 294,000 lbs., the engine is designed to help loft heavy payloads–such as habitats, landers and in-space modules–beyond low-Earth orbit.
