The present invention relates in general to aeronautical engineering and concerns specifically transport vehicles for transportation of liquid and loose cargoes. The invention provides an airborne vehicle capable of carrying a multiton cargo from a limited ground area. The object of the invention is accomplished due to the fact that in the airborne vehicle of the present invention the lifting aerodynamic airfoil system is made of two parts, that is, a stationary part in the form of a ring-shaped fuselage 1, consisting of aerodynamic members 2 and 3 curve...
A multipurpose airborne vehicle, comprising a fuselage, a wing, and a power unit, the fuselage having spanwise-curved aerodynamic lifting airfoils joined together in a horizontal plane of the vehicle to form a ring, the power unit having several gas-turbine engines, each having a ramjet duct, a shortened jet nozzle, an after-burner, and a flywheel member, said vehicle also having rotor units with blades and also provided with a control actuator for the blades, the rotor units having nozzles arranged along the axis of rotation at the ends of the rotor bla...
