Pratt and Whitney Rocketdyne successfully completed the first in a series of powerpack hot-fire tests on the J-2X engine, which is being developed for NASA to power humans further into space than ever before.
Powerpack tests are designed to evaluate the full range of operating conditions of the engine's components during flight. NASA selected the J-2X as the upper-stage propulsion for the Space Launch System (SLS) - an advanced heavy-lift launch vehicle. Pratt and Whitney Rocketdyne is a United Technologies Corp. company.
"The successful powerpack test provided important data that verified the engine's components and gave us a better understanding of how the turbopumps operate," said Walt Janowski, J-2X program manager, Pratt and Whitney Rocketdyne.
"Each new test brings us closer and closer to engine certification, and we are confident the J-2X will be ready to power humans to destinations in space never before visited, including asteroids and Mars. We look forward to working with NASA on the future of human spaceflight."
The powerpack consists of components on the top portion of the engine, including the gas generator, the oxygen and fuel turbopumps, and the ducts, valves, and controls that bring the propellants together to drive the turbines of the two turbopumps.
Pratt and Whitney Rocketdyne will perform hot-fire tests on the powerpack through summer, using varying pressures, temperatures and flow rates to ensure the engine is ready to support exploration to low-Earth orbit, Mars and possibly beyond.
Pratt and Whitney Rocketdyne, a part of Pratt and Whitney, is a preferred provider of high-value propulsion, power, energy and innovative system solutions used in a wide variety of government and commercial applications, including engines for launch vehicles, missile defense systems and advanced hypersonic engines.
Behind its successful designs, manufacturing processes, and hardware are Pratt and Whitney Rocketdyne's research and development engineers, who solve tough problems in extreme environments.

Europe stakes billion-dollar bet on new rocket
Paris (AFP) Feb 11, 2012
A pencil-slim rocket is scheduled to lift into space from South America on Monday, carrying a billion-dollar bet that Europe can grab a juicy slice of the market to place satellites in low orbit. The maiden flight of Vega culminates a decade-long plan to turn Europe's space base in Kourou, French Guiana, into the world's most versatile launch platform. The launcher 30 metres (100 feet) l ... read more
