Abstract
The present disclosure provides a rear nacelle assembly for a turbojet having at least one thrust reversal device to redirect air circulating from upstream to downstream in a flow path of a turbojet and a mast that connects the nacelle to a structure of an aircraft. In one form, the thrust reverser device includes a cradle having a first longeron and a second longeron extending longitudinally opposite sides of the mast. The first and second longeron each include a device for slideably guiding the cowl and the cascade. In another form, a rear portion and a front portion of the cradle connects to the mast by a rear connecting device and front connecting device, respectively, such that the cradle is adapted to follow the movements of the turbojet.
Claims12
A nacelle rear assembly for a nacelle of a turbojet engine comprising:
- at least one thrust reverser device to redirect air flow circulating from upstream to downstream in a flow path of the turbojet engine and a mast that connects the nacelle on a structure of an aircraft, the nacelle extending longitudinally from forth to back along an axis, the thrust reverser device comprising:
- a cowl movably mounted in longitudinal translation from forth to back along a direction parallel to the axis of the nacelle, between a closing position in which the cowl provides aerodynamic continuity of the nacelle, and an opening position in which the cowl opens a passage in the nacelle, and
- at least one sliding thrust reverser cascade driven by the cowl between a retracted position between a fan casing and an outer envelope of the nacelle corresponding to the closing position of the cowl, and a thrust reversal position corresponding to the opening position of the cowl, the sliding cascade being displaced downstream so as to be able to extend through said passage opened by the cowl in the thrust reversal position;
- and
- a cradle comprising a first longeron and a second longeron, the first and second longeron extending longitudinally on opposite sides of the mast,
- wherein the first and second longerons each include a device for slidably guiding the cowl and the sliding thrust reverser cascade,
- wherein a rear portion of the cradle is connected on the mast by a first rear connecting device and a front portion of the cradle being connected on the turbojet engine by a second front connecting device, so that the cradle is adapted to follow movements of the turbojet engine.
