cryogenic upper stage engine is currently under development by Pratt & Whitney of West
Palm Beach, Florida. It is a new design but follows in the footsteps of the RL-10,
which was developed in the late 1950's and powers the Centaur upper stage. The
company is projecting that this advanced engine will be available in 2003 for several
different launch vehicles.
The RL-60 expander cycle engine will be
approximately the same size as the RL-10, allowing for direct substitution with minimal
vehicle modifications. The engine will produce 50,000 to 65,000 pounds of thrust
with a specific impulse above 470 seconds. Pratt & Whitney is designing the
RL-60 engine to meet the needs of current and future launch vehicles and payloads.
