Pratt & Whitney F135 engine upgradation

RPratt & Whitney has completed performance testing of its Fuel Burn Reduction Demonstrator Engine and the company can now offer a Growth Option 1.0 upgrade configuration for the F135 engine, which powers the fifth generation F-35 Lightning II fighters. The engine testing, conducted at Pratt & Whitney’s West Palm Beach, FL, facility, verified this upgrade can provide a 5 to 6 percent fuel burn improvement and a 6 to10 percent thrust increase across the F-35 flight envelope. While the current production F135 engine meets current performance requirements, an F135 propulsion upgrade would enable future capability improvements associated with the F-35 weapon system’s block upgrade programme.
