General Electric YJ101

The General Electric YJ101 was an afterburning turbofan engine in the 15,000 lbf class (static thrust). Developed for the Northrop YF-17 entry in the Lightweight Fighter (LWF) competition, the YJ101 formed the basis for General Electric's highly successful F404 engine.

The bypass ratio was intentionally designed to be very low, to avoid the inlet instability issues associated with earlier TF30 engines on the F-111. For marketing reasons, the engine was designated as a "J" (jet) type, and not an "F" (fan) engine. In fact, some engineers described the YJ101 as a "leaky turbojet".
