Abstract:
In the field of aviation, a device for limiting aerodynamic noise from a deployed aircraft undercarriage during landing and/or takeoff. The device comprises two end plates (4a, 4b) for closing respective ends (2a, 2b) of a hollow pin (1) of the undercarriage, such as a hinge pin between two rods of the undercarriage, together with at least one tie (6) for engaging inside the hollow pin (1) to connect the two end plates (4a, 4b) together so as to hold them pressed against the ends (2a, 2b) of the pin (1).
