FIELD: transport for large-sized cargoes and large-tonnage liquid and loose cargoes. SUBSTANCE: flying vehicle is made in form of annular wing consisting of two halves connected in horizontal plane and made of set of profiles of various curvature forming optimal aerodynamic lifting surface; power plant includes composite turboramjet engines built in annular wing in direction of profile chords at similar interval between them and rotor units made in form of controllable multi-bladed main rotors with jet-drive. EFFECT: enhanced reliability. 6 dwg
