Abstract

A secure corset is applied in particular to the immobilization in the maximum opening position of an aircraft landing gear cage hatch. The corset has two half-shells that are able to enclose the piston of the actuator having an axis coincident with the common longitudinal axis of the half-shells once they are closed around the piston. Locking pins are able to hold the half-shells around the actuator. The corset also has a casing secured to at least one of the half-shells and equipped with a hooking unit that is able to be coupled to a fixed point on the structure. A structure for varying the distance between the casing and the hooking unit are able to move the hooking unit away from or towards the corset along the common longitudinal axis of the half-shells.

Claims8

Dependent claims

A corset for securely locking a piston of an actuator of a landing gear cage hatch of an aircraft, the corset having a longitudinal axis, the corset comprising:

a locking unit structured to secure an opening position of a shutter of the landing gear cage hatch, the shutter being mounted on a structure of the landing gear cage hatch, the locking unit being structured to lock the piston at a position corresponding to a defined opening position of the shutter;
a control unit fastened to the locking unit;
an attacher structured to be coupled to a fixed point of the structure of the landing gear cage hatch;
and
a distance varying unit structured to be coupled to the control unit and the attacher and to vary the distance between the control unit and the, attacher to move the attacher further away from or closer to the locking unit along the longitudinal axis.
