The tests on the J-2X
engine bring NASA one step closer to the first human-rated liquid oxygen and liquid hydrogen rocket engine to be developed in 40 years.
The powerpack is a system of components on the top portion of the J-2X
engine, including the gas generator, oxygen and fuel turbopumps, and related ducts and valves.
The determination and focus by teams at NASA's Marshall Space Flight Center and Stennis on designing and perfecting the J-2X
engine helps show the great strides of progress made on the overall program," said SLS Program Manager Todd May.
17, 2012 /PRNewswire/ -- Pratt & Whitney Rocketdyne successfully completed the last hot-fire test on the J-2X
powerpack -- an important step toward development of America's next rocket engine designed for human spaceflight.
NASA already has conducted successful tests on engine number 10001 and on the J-2X
The PWR decision to select Volvo Aero for the pre-study of the J-2X
is yet another acknowledgment to Volvo Aero that the development efforts, supported by SNSB, have been well spent money.
Fueled by liquid hydrogen and liquid oxygen, the J-2X
engine will generate 294,000 pounds of thrust to lift a spacecraft into low-Earth orbit.
25 for a behind-the-scenes look at the facilities used for testing the J-2X
engines that will launch astronauts on missions to deep space aboard the Space Launch System (SLS).
The successful J-2X
engine test is the latest milestone on Pratt & Whitney Rocketdyne's journey to help the nation safely and reliably return humans to space," said Jim Maser, president, Pratt & Whitney Rocketdyne.
9, 2011 /PRNewswire-USNewswire/ -- NASA conducted a successful 500-second test firing of the J-2X
rocket engine on Wednesday, Nov.
It will use a liquid hydrogen and liquid oxygen propulsion system, relying on the space shuttle's RS-25 engine for the core stage and the J-2X
engine for the upper stage.
In addition to the successful margin demonstration testing of the RS-68A engine, Pratt & Whitney Rocketdyne, together with NASA, has begun testing on the upper-stage J-2X
