General Electric F404

The General Electric F404 is a turbofan engine with afterburner of GE Aviation in the class of about 85 kN thrust.

The F404 was originally developed for the F/A-18. Base was the YJ101 - engine, which was intended for the never produced in series YF -17. Compared with this, the bypass ratio was increased from 0.25 to 0.4. Furthermore, GE stayed in the development of the engine at short reaction times when changing the thrust requirement by the pilot, trouble-free operation (no flow separation at the inlet ) even during extreme maneuvers, as well as an integrated control and monitoring system.
