The General Electric F414 is an afterburning turbofan engine in the 22,000 lb_f (98 kN) thrust class produced by GE Aviation. The F414 was developed from GE's widely-used F404 turbofan for use in the Boeing F/A-18E/F Super Hornet.

Design and development

Origin

GE evolved the F404 into the F412-GE-400 non-afterburning turbofan for the A-12 Avenger II. After the cancellation of the A-12, the research was directed toward an engine for the F/A-18E/F Super Hornet. GE successfully pitched the F414 as a low-risk derivative of the F404, rather than a riskier new engine. In fact, the F414 engine was originally envisioned as not using any materials or processes not used in the F404, and was designed to fit in the same footprint as the F404."Confident GE heads to F414 CDR next month" (1994).

Design

The F414 uses the core of the F412 and its full-authority digital engine control (FADEC), alongside the low-pressure system from the YF120 engine developed for the Advanced Tactical Fighter competition. One of the major differences between the F404 and the F414 is the fan section. The fan of the F414 is larger than that of the F404, but smaller than the fan for the F412."GE wins F-18E/F study" (1991). Flight......
