Summary:flying vehicles. SUBSTANCE: proposed ground-effect machine has fuselage with replaceable support elements of undercarriage, low lifting wing and upper lifting wing mounted over low wing. Main wing consisting of right-hand and left-hand sections forming air cushion chamber is arranged between low and upper wings. Engine with tractor propeller is mounted in fuselage nose, and horizontal and vertical tails with elevator and rudder are mounted in rear fuselage. Span of main wing is equal to span L of low wing made with span L equal to 0.5-0.85 of span L1 of upper wing. Central parts of lower surfaces of right-hand and left-hand sections of main wing are located lower than axis of rotation of tractor propeller by 0.05-0.15 D of tractor propeller. Radius R of curvature of lower surfaces of right-hand and left-hand sections of main wing and area S of projection of its lower surface in plan are equal to 0.2-0.3 of span L and 0.85-0.89 of area S1 of projection of upper wing surface in plan. Length M of chord of main wing is equal to 0.85-1.15 of span L of the wing. EFFECT: improved efficiency in operation, simplified design. 4 cl, 3 dwg
