ALIGHTING GEAR FOR GROUND-EFFECT TAKE-OFF AND LANDING AEROPLANES (VERSIONS)

摘要

FIELD: aeronautical engineering; designing of alighting gears for ground-effect take-off and landing aeroplanes. 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 in form of hydraulic shock absorbers 4 which are mounted in center of mass of aeroplane on rear portion 6 of load-bearing beam 3; tail and nose portions of floats 2 are secured on aeroplane fuselage for circular and longitudinal motion; shock absorbers 4 may be provided with hydraulic system 15 for positive extension of rod of shock absorber 4. In one version, shock absorbing member is made in form of inflatable bottle 19 provided with air inlet and outlet device. EFFECT: soft landing without excessive lateral drag and head resistance (drag); without increase of aeroplane mass; simplified construction and reduced pitching moment. 3 cl, 10 dwg
