ABSTRACT OF THE DISCLOSURE The present invention provides a retractable fuselage mounted landing gear for an aerodyne comprising undercarriages which are pivotally moved in a rearward direction of the aerodyne upon retraction, each undercarriage including a leg member associated with shock absorber means and mounting at least one wheel, the leg member being mounted so as to pivot on the aerodyne about an articulation axis and cooperating with a breakable strut and a strut actuating jack having at least one internal locking device, in which the breakable strut comprises an arm and a rod articulated to one another by one of their ends, the arm being articulated at its other end to a fixed point on the aerodyne and the rod being articulated at its other end to a fixed point of the leg member, the jack being articulated to the arm at a fixed position thereon and to a fixed point of the aerodyne, whereby in the undercarriage-down position, the jack is substantially aligned with the rod in such a way that aerodynamic forces which oppose lowering of the undercarriage act to assist locking of the strut actuating jack and consequently the undercarriage in the undercarriage-down position, and also assist raising of the undercarriage beyond the alignment position of the rod and the arm.
