Big Blast Nearly There...
Pratt & Whitney Space Propulsion this month
received a main fuel (hydrogen) turbopump from Ishikawajima-Harima
Heavy Industries Co. for the development of its new RL60 engine.
The RL60 has 90% of its components complete and is expected to
begin full testing in September.
The RL60 is a cryogenic upper-stage engine designed to produce
60,000 pounds of thrust with a specific impulse of 465 seconds to
meet the evolving needs of expendable launch requirements or
"The RL60 is truly the next generation upper-stage rocket
engine," Pratt & Whitney Space Propulsion and Russian
Operations President Larry Knauer said. "By leveraging 40 years of
expander cycle experience with the latest technology, we are able
to offer a high-performing, high-flexibility engine that can fire
multiple times in space."
The reception of the main fuel turbopump, which consists of a
two-stage Centrifugal Pump and two-Stage Axial Flow Turbine and
Ceramic ball bearings, will allow P&W to verify the performance
of the component by installing it on the RL60 engine
