Landing-gear assembly for an aircraft, the landing-gear assembly including a secondary shimmy damper

A landing-gear assembly (1) for an aircraft, the landing-gear assembly comprising:

• an axle shaft (2) arranged to carry wheels for enabling the aircraft to run on the ground;
• a leg (3) presenting a first portion (3a) carrying said axle shaft (2) and a second portion (3b) adapted to be connected to a carrier structure of the aircraft, said leg extending along a main axis of the leg passing via said first and second leg portions;
• a main damper (5) arranged to damp axial movements of the first leg portion (3a) relative to the second leg portion (3b);
• a first secondary damper (6a) distinct from the main damper (5), characterized in that said first secondary damper (6a) is carried by said axle shaft (2), said first secondary damper (6a) comprising:
• an inertial mass (M);
• and
• first connector (7a) connecting said inertial mass (M) to said axle shaft (2) in order to enable said inertial mass (M) to move about at least one first axis of movement (X1) of said inertial mass (M) relative to the axle shaft (2) and in order to enable said inertial mass (M) to oscillate along said at least one first axis of movement (X1) on either side of a stationary rest position relative to the axle shaft (2), said first connector (7a) being adapted to damp said movements of said inertial mass (M) relative to said axle shaft (2) about said at least one first axis of movement (X1), said first axis of movement (X1) extending in a plane (P) perpendicular to said main axis (Z).
