Abstract

An aircraft nacelle includes an air intake (12) followed at the upper part by a part (14) integral with the mast, called a cap, and at least one door (16) with a curved profile, and a device for encircling it in the form of at least one flexible element (38), guide elements (40) for allowing the at least one flexible element (38) to follow the curved profile of the at least one door, a first anchoring point (42) of the at least one flexible element (38) integral with a first edge (78) of the cap and another anchoring point of the at least one flexible element (38) integral with a second edge (80) of the cap, whereby the anchoring points (42) allow a relative translational movement, in a direction that is parallel to the longitudinal axis of the nacelle, between the cap (14) and the at least one door (16).

Dependent claims

An aircraft nacelle comprising:

an air intake with a cap at an upper part and a door with a curved profile, the cap being integral with a mast and the door being movable along a longitudinal axis of the aircraft nacelle;
a flexible element that extends around an interior surface of the door;
a guide that causes the flexible element to follow the curved profile of the door;
and
a first anchoring point for the flexible element that is attached to a first edge of the cap and a second anchoring point for the flexible element that is attached to a second edge of the cap,
wherein the first and second anchoring points each comprises an axis attached to the cap and extending along the longitudinal axis of the nacelle, and wherein the flexible element comprises a ring at each end, each ring being adapted to slide along a respective said axis so as to permit relative translational movement, in a direction parallel to the longitudinal axis of the nacelle, between the cap and the door.
