Abstract

A nacelle for double-flow engine with a cowling and at least one thrust reverser, the thrust reverser having an internal door and an external door arranged in the cowling, and means for simultaneously shifting these doors between a stable retracted position in which the doors are integrated in the cowling and a stable deployed position in which the internal and external doors are positioned at least partially inside and outside of the nacelle, respectively, to deflect the secondary flow and to generate a thrust reversal. The means for simultaneously shifting the doors comprise an actuator, one extremity of which is linked to one of the doors to shift this door between the extreme positions, and at least one linkage element linked to the doors to pivot by its extremities, so that the shifting of the door entails the shifting of the other door between these extreme positions.
