FIELD: aeronautical engineering. SUBSTANCE: alighting gear has side skegs made in form of inflatable floats 2 and connected with aeroplane fuselage 1 by means of shock-absorbing members made in form of hydraulic shock absorbers, longitudinal and lateral motion limiters; shock absorbers are arranged in nose and tail portions of floats 2 and rest against load-bearing beams provided for floats and secured on them; shock absorbers are articulated, respectively, on aircraft fuselage 1 and on beams; limiters are made in form of torque links articulated, respectively, on aircraft fuselage and on beams; limiters are mounted, respectively, in nose and tail portions of floats 2 perpendicularly to longitudinal axis of aircraft and limiters are mounted in area of center of mass of aircraft in parallel with its axis; fitted in nose and tail portions of floats 2 are locks securing the floats to the aircraft fuselage. EFFECT: soft landing without excessive drag and lateral drag, without increase of aircraft mass and complexity of its structure; reduction of pitching moment. 9 dwg |
