摘要： A nacelle has a fixed cowl and a mobile cowl, which is movable along a translation path between closing and opening positions, a window delimited by the fixed cowl and the mobile cowl and open between an airflow and exterior of the nacelle, a reverser flap rotatably mounted to move between closed and open positions, and a drive mechanism configured to control passage of the reverser flap between the closed and open positions as the mobile cowl moves between the closed and open positions. From the closing/closed positions, the drive mechanism assures a translation of the mobile cowl and a rotation of the reverser flap toward their respective opening/open positions. From the open/opening positions, the drive mechanism assures a rotation of the reverser flap and a translation of the mobile cowl toward their respective closed/closing position. In some embodiments, the nacelle further includes an additional, or second, flap.

摘要： An aircraft nacelle air intake structure including an air intake lip with a U-shaped section to ensure air is shared between an inner face and an outer face. An acoustic panel is on the intake lip rear on the side of the inner face level with a first assembly point. An outer panel is on the intake lip rear on the side of the outer face level with a second assembly point. A front reinforcing frame on the intake lip inside is fixed to the air intake lip on the side of the inner face level with a first fixing point and on the side of the outer face level with a second fixing point. The length of the chord between the stop point and each fixing point is between ⅓ and ⅙ of the total chord between the stop point and the assembly point.

摘要： A turbofan including a motor with a fan casing and a nacelle which includes a mobile cowl and a main slider bearing gratings and being mobile in translation between an advanced position and a retracted position in which the mobile cowl and the fan casing define, between them, a window. The nacelle also includes reverser flaps, each one being mounted articulated on the main slider between a closed position in which it obstructs the window and an open position in which it does not obstruct the window, a secondary slider mounted mobile in translation on the main slider between a first position and a second position, a transmission system configured to make each reverser flap pass from the closed position to the open position when the secondary slider passes from the first position to the second position, and a set of actuators that bring about a movement in translation of the main slider, and of the secondary slider.

摘要： 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.

摘要： A locking system for locking a cowl to a fixed structure including first and second parts, the first part including a first hook moveable on the cowl and a first shaft fixed to the fixed structure in which the first hook is moveable between locked and unlocked positions, in which the second part includes a handle actuateable between closed and open positions, a second hook and a second shaft fixed to the fixed structure or to another cowl symmetric with the cowl, in which the second hook is moveable between locked and unlocked positions and in which the second hook is mounted where passage of the handle from the closed to open positions causes the second hook to pass from the locked into the unlocked position and vice versa, and in which the locking system also includes a transmission system to move the first hook from the locked into the unlocked position when the handle passes from the closed into the open position, and vice versa.
