Abstract

The invention relates to flying vehicles. A centre wing is provided with aerodynamic profiles on the longitudinal sections thereof. A cigar-shaped fuselage is arranged on the central wing. A crew cabin and a cargo-passenger cabin are arranged inside the fuselage. Hollow hermetical longitudinal beams are mounted on the periphery of the central wing on the sides thereof. Inflatable shock-absorbing balloons are arranged under said longitudinal beams. Two keels provided with rudders are mounted on the ends of the longitudinal beams. A horizontal tail is arranged on the keels and comprises a diving rudder which is disposed on a section between the keels and ailerons which are disposed on the sections of the longitudinal beams. The thrust propeller for horizontal thrust is accommodated inside an external annular cowl. The engine for the thrust propeller is arranged inside the tail cone of the fuselage. A set of tale-off and landing devices comprises a means for producing a static air cushion. The cruising flight of the inventive ground-effect craft is carried out by the propeller thrust and a lifting force produced by the interaction of the central wing and a ram air and by the ground-effect of a ground or water surface. The height over ground or water surface must be equal to 0.1-0.5 of the mean chord of the central wing or to 0.2-0.9 of the span thereof when the angle of attack of the central wing is equal to 5-6.degree., the horizontal propeller thrust ranges from 0.25 to 0.33 of the flying weight of the craft and the speed is equal to 200-280 km/h.
