Abstract

The invention discloses a high-altitude unmanned plane equipped with a Magnus effect propulsion system, wherein double-fuselage layout is adopted by the high-altitude unmanned plane; wings are mounted on external sides of two fuselages; a Magnus effect propulsion system and an empennage are mounted between the two fuselages; a propeller is mounted on the head of the fuselage; and thin-film solar cells are covered on the upper surfaces of the wings. A Magnus effect rotor can be used as a lifting device in the daytime; under the same flow velocity, the lifting force can be greatly improved by only improving rotation speed of the Magnus effect rotor, so that enough lifting force is provided for the unmanned plane even in low-speed flight, the minimum takeoff speed and the cruising speed of the unmanned plane are reduced and the short takeoff and landing and aerial low-speed cruise investigation of the unmanned plane are facilitated; the Magnus effect rotor can be used as a wind power generation device in the night for generating power by using the high-altitude stable and sustained wind energy, so that the shortage of large wing area or wingspan of the unmanned plane with the sole capability of obtaining solar energy at low energy density in the daytime for storing energy for flight is avoided.

Description

technical field [0001] The invention belongs to the technical field of aircraft, in particular to a high-altitude unmanned aerial vehicle equipped with a Magnus effect propulsion system. Background technique [0002] The classic Magnus effect refers to a phenomenon in which a rotating cylinder moving in a viscous incompressible fluid is subjected to a lifting force. For example, when a soccer ball moves in the airflow, if the rotation direction of the upper spherical surface is in the same direction as the airflow, it will drive the airflow near the upper spherical surface to increase the flow velocity on the upper spherical surface and generate low pressure; The spherical surface creates high pressure, which creates lift. At present, the application of Magnus effect is mainly as the propulsion device of ships and the rotor of wind power generation. [0003] Magnus effect rotors can be used as a propulsion system for ships due to strong offshore winds. Chinese patent CN10...
