General Electric F404

Test run of an F404-GE-402 aboard the USS Abraham Lincoln

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 McDonnell Douglas F / A-18 . The basis was the YJ101 engine, which was intended for the YF-17 , which was never mass-produced . Compared to this, the bypass ratio was increased from 0.25 to 0.4. In addition, when developing the engine, GE paid attention to short response times when the pilot changes the thrust requirement, trouble-free operation (no flow stall at the inlet) even during extreme flight maneuvers, and an integrated control and monitoring system.

variants

Due to the success of the F404 in the F-18, GE decided to develop variants for the F-15 and F-16 as well.
