F135 Turbofan

The F135 turbofan engine with afterburner is a improved version of the F119-PW-100 (F-22 Raptor) and is specially designed for the new 1-engine F-35 Lightning II (JSF). P&W hopes to being awarded as the engine deliver for all 3 versions (conventional takeoff and landing (CTOL), carrier-variant takeoff and landing (CV) and the short takeoff and vertical landing (STOVL).

The F135 engine is the most powerful fighter jet engine ever build. It produces a thrust of more than 40,000 pounds. This in comparison with the first CF6 engine for the Boeing 747 which had a thrust around the 40,000 pounds.

Just as the F119, the F135 has a 6-stage compressor, 1-stage turbine unit with a new Low pressure turbine (LPT). Pratt & Whitney developed the engine as maintenance friendly for example by reducing the engine components with 40% in comparison with current fighter jet engines. It is also equipped with automatic field data and test systems.

All 3 Lightning II version will get probably the F135 engine from Pratt and Whitney which differs a little bit.
