Abstract: 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.
