A turbofan with a nacelle having a fixed structure, a mobile assembly bearing second blocking element and able to move between an advanced position and a withdrawn position, a set of deflectors able to move in translation between an advanced position and a withdrawn position, and an actuation system having a carriage, a blocking lever bearing first attachment element and able to move between a blocking position and a free position, and a transmission system configured to move the blocking lever from the blocking position to the free position when the mobile assembly reaches a tilting position between the advanced position and the withdrawn position.

Turbofan having mobile deflectors and a system for actuating the deflectors

A nacelle having a fan casing, a cowl that movable between an advanced position and a retracted position that opens an opening between a bypass duct and the outside, deflectors secured to the mobile cowl, wherein, in the advanced position, they are around the fan casing and wherein, in the retracted position, they are across the opening, and a fan ramp with a mounting base and flaps that are able to rotate on the mounting base between a stowed position and a deployed position. For each flap, the fan ramp has a return element that urges the flap) into the deployed position, and the deflectors have a stop in contact with the flap when the mobile cowl passes from the retracted position to the advanced position. Thus, in the advanced position, the flaps are folded back and their bulk is reduced.

Aircraft nacelle having a fan ramp with articulated flaps

A turbofan including a motor, nacelle and a secondary duct therebetween. The nacelle includes a fan casing with front and rear parts, a fixed assembly including a fixed structure and the front part, a mobile assembly with an openwork frame, a mobile cowl and the rear part and mobile between advanced and retracted positions in which a window is open between the secondary duct and the exterior of the nacelle, inner doors articulated between stowed and deployed positions, a first actuator for moving the frame and a second actuator for moving each inner door. The rear part is divided into outer flaps mobile between lowered and raised positions and is moved by an electric motor. A jet engine accordingly serves to increase retraction distance by freeing up part of the fan cowl and improve orientation of flow of air passing through the window by orienting the outer flaps.
