This paper describes the transition of the Atlas/Centaur RL10 engine to the Shuttle/Centaur configurations; shows the unique versatility and capability of the engine; and highlights the importance of ground testing. Propulsion testing outcomes emphasize the value added benefits of testing heritage ...
The RL10 liquid hydrogen/liquid oxygen engine traces its origin towork performed by P&W in the mid 1950s. The first RLI0 was delivered to NASA in 1961. Since then, 258engines have been flown, with 490 firings. Seven different models of the RL10 have been delivered, and two more are ...

A few years ago, the RL10C engine, the latest newcomer in the RL10 family developed by AR, has been selected by ULA to power the Atlas V upper stage in its RL10C-1 version, and more recently by NASA as the engine for the Exploration Upper Stage (EUS) of the Space Launch System (...
Although development of the RL10E-1 was not completed, the engine development tests were highly successful in demonstrating engine operation with the full authority, digital electronic control system and fewer valves. Many of the enhanced reliability features have been demonstrated and are directly ...
Informs on the logging of its first mission by Pratt & Whitney's newest RL10 rocket engine on January 10, 1995 with the launch of a Martin Marietta II AS rocket which boosted the Intelsat VII communications satellite into the orbit. Details of the engine.Dasch...
The convoluted nozzle is included in a study of extendible nozzles for the RL10 Engine Derivative 2B for use in an early orbit transfer vehicle (OTV). Four extendible nozzle configurations for the RL10-2B engine were evaluated. Three configurations of the two position nozzle were studied ...
