ABSTRACT:
A turbofan, preferentially with separated-flows or short nacelle, comprises two thrust reversal doors normally housed in casings formed in the nacelle and located totally outside the inner enclosure of the nacelle. When a thrust reversal effect is sought, the doors are directed in the prolongation of the fan channel, behind the rear end of the nacelle. Thus, the doors are not submitted to the engine bypass air of the jet engine when the aircraft is in flight and the inner enclosure of the nacelle presents neither leak nor discontinuity and may be totally anti-noise treated.
