Less than a year after the GE Rolls-Royce Fighter Engine Team tested its F136 engine for the F-35 Joint Strike Fighter (JSF), the team has achieved several milestones - including completion of all pre-System Development & Demonstration (SDD) testing ahead of schedule and under budget. Successful completion of pre-SDD testing clears the way for the award of a SDD contract, which is expected in August.
The F136 engine will be fully interchangeable with the competing Pratt & Whtiney F135 engine to power the F-35 JSF aircraft, and with all three aircraft versions: STOVL for the U.S. Marine Corps and U.K. Royal Navy, CTOL for the U.S. Air Force, and the Carrier Variant (CV) for the U.S. Navy.
The main goal of Phase III testing was to test a full turbofan engine in both the Conventional Take-Off and Landing (CTOL) and Short Take-Off and Vertical Landing (STOVL) configuration. The two F136 engines in the Phase III tests accumulated more than 200 hours of testing, including 18 hours of STOVL testing.
With the infusion of best practices and improved technology, the F136 is expected to exceed requirements for maintainability, affordability, and reliability for all JSF variants, while enhancing the ability of the U.S. services and international partners to cooperate in joint coalition operations.
Based on the current schedule, SDD development testing commences in 2006 and culminates with delivery of the first F136-powered F-35s in 2012.
