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.
