Landing gear for aerodynes, with crosspieces in composite material

A landing gear for an aerodyne comprising two lateral members for contact with the ground aligned with a longitudinal axis of the aerodyne, said members being linked together and to the fuselage of the aerodyne by at least two crosspieces wherein:

• each of the crosspieces is a curved beam constituted by a monolithic laminated material of high-strength fibers agglomerated by thermo-setting synthetic resin,
• the cross-section of each crosspiece is polygonal and substantially constant and in the region of its extremities substantially square with rounded edges,
• the crosspieces are constituted by a core formed by longitudinal fibers, surrounded by a shell of tissues whose threads are oriented at plus or minus 45.degree. with respect to the longitudinal fibers,
• the members for contact with the ground are rigid, hollow and closed profiles whose two lateral walls are parallel and vertical,
• the crosspieces are, at their extremities, rigidly embedded onto the members for contact with the ground by penetration of the extremity of the crosspiece inside the profile and integration of the lateral faces of the crosspiece onto the sides of the profile by securing members extending therethrough, and
• the crosspieces are fixed at the lower part of the structure of the fuselage of the aerodyne by an articulated link permitting limited rotation of the crosspieces about parallel transverse axes of the aerodyne and relative angular deformations of the crosspieces with respect to the structure in the vertical plane and in the horizontal plane.
