FIELD: aviation.
SUBSTANCE: invention relates to aircraft landing gear. Main undercarriage of aircraft landing gear comprises landing gear housing (1) connected in upper part to rotary crossbar (5) by means of hinged joint (7). Rotary crossbar (5) is installed by means of rotary attachment units (6) on beam (21) of crossbar fixed on wing spar (12). Shock absorber strut brace (2) is rigidly connected to rotary crossbar (5) on one side and pivotally connected to lower part of housing (1) of shock absorber strut by means of rotary clevis (3). Hinge assembly (7) is an axially connected lug made in the upper part of housing (1) of the shock-absorbing strut, and an lug made on rotary crossbar (5) at the abutment point of brace (2), in particular, in the abutment point of side wall (17) to crossbar (5).
EFFECT: invention makes it possible to prevent destruction of aircraft wing box at emergency landing and, therefore, allows to reduce probability of fire occurrence due to fuel leakage.
