Stennis Space Center, MS, USA   |   production facility

A Pratt & Whitney RS-68 rocket engine, designed for the Delta IV family of expendable launch vehicles, undergoes a test at Stennis Space Center. The bell-nozzle RS-68 is a liquid hydrogen-liquid oxygen booster engine. It was the first new American booster engine developed in over 25 years. Simplicity was the primary design goal, resulting in 80 percent fewer parts than the Space Shuttle Main Engine. Each engine costs about $14 million to build. In 2006 NASA announced that 5 RS-68 engines would be used instead of SSMEs on the planned Cargo Launch Vehicle. The cost with upgrades is $20 million per engine. NASA photo.

Trent 900 / Trent 1000

Rolls-Royce International Ltd. will spend $42 million to open a jet engine test complex at Stennis Space Center. It will test engines for performance, noise and other factors. Slated to be tested are the Trent 900 and Trent 1000, used on Airbus and Boeing aircraft. Testing will begin in 2007. Rolls-Royce is closing test operation in the United Kingdom because of encroachment issues.  Rolls-Royce photo

Wiseman Engine

Wiseman Engine
Biloxi, MS   |   in development

Wiseman Technologies is marketing a unique engine that is more efficient than conventional piston types. Both two and four stroke prototypes have been built and tested, and a diesel version is under development. This internal combustion engine utilizes special gear that allows the crankshaft to operate in an entirely linear movement, thus reducing friction. Because of its weight and efficiency, it could have implications for the UAV industry. Wiseman Technologies photo.
