Contact: Patrick Louden Tel: (561) 796-6793 Web Site: www.pw.utc.com Pratt & Whitney Space Propulsion – RL60 Pratt & Whitney is applying its unmatched 40 years of expander cycle, cryogenic upperstage engine experience to the development of the RL60. This new high-performance offering is designed to produce 60,000 pounds of thrust and meet the evolving needs of expendable launch requirements or human-rated missions. RL60 will provide more than double the thrust of the company’s venerable RL10 engine for increased performance and launch capability. The RL60’s expander cycle gives the engine greater range of operation, including multiple firings in space. The engine also offers flexibility as it can operate anywhere within a range of 50,000 to 65,000 pounds of thrust. The RL60 demonstration phase is now underway with component testing completed. Demonstrator engine testing is planned for mid 2003. Characteristics Thrust: 50,000 to 65,000 lb Weight: 1,100 lb Specific impulse: 465 sec Cycle: Full expander Propellants: LH2/LOX Mixture ratio: 4.5 to 6.2 NPSP LH2/LOX: <2.0 psi Restarts: Multiple
