Abstract
A nacelle comprising a fixed structure, a fixed cowl, a mobile cowl, and a motor arrangement to translationally displace the mobile cowl from a closed to an open position on the fixed structure. The nacelle comprises a window delimited between the fixed and mobile cowls and open between a secondary turbojet and the outside, a thrust-reversing door rotationally mobile about a rotational axis between retracted and active positions, and a driving mechanism which coordinates and defers the switch from the retracted to the active position with the switch from the closed to the open position. The driving mechanism comprises two connecting rods rotationally mobilely mounted on the fixed structure and bearing a wheel, a mobile cowl groove which slidingly receives the wheel, a guide integral to the thrust-reversing door, and a runner rotationally mobilely mounted between the connecting rods, as well as mounted to slide along the guide.
