초록

A turbofan engine is provided that includes a core nacelle at least partially surrounded by a fan nacelle. The core nacelle includes a reflex nozzle providing a core exit. The core nacelle includes a contour on its exterior surface upstream from the reflex nozzle. The contour is generally conical and tapers toward the core exit at a first slope. The reflex nozzle tapers toward the exit at a second slope that is less steep than the first slope. The reflex nozzle includes a generally linear portion. In one example, the reflex nozzle is provided by a genera...
