Aerodynamic device

Abstract

An aerodynamic device belongs to the technical field of aircraft, and includes wings, a propeller and a bracket. The wings are located above the propeller, and include a front wing, a rear wing and a wing shaft; The wing shaft and the propeller rotation plane are parallel; the front wing and the rear wing are respectively arranged on the front and rear sides of the wing shaft; the rear wing under the action of external force can swing around the wing shaft flexibly; and with the horizontal plane as the base, the front wing tilts upwards in front of the wing shaft. The propeller comprises a propeller body and a propeller shaft; the propeller shaft is arranged on the bracket fixed on the wing shaft through a bearing; power drives the propeller to rotate; under the interaction of the propeller and wings, the device produces great thrust convenient to adjust the direction and level; and the level and direction of the thrust can be adjusted by adjusting the rotation speed of the propeller and the included angle of the rear wing and the horizontal plane. The device has the advantages of small resistance, high efficiency, high lift-drag ratio and strong mobility, and is applicable to vertical lifting heavy load low-speed aircraft.

Description

technical field [0001] An aerodynamic device belongs to the technical field of aircraft, and in particular relates to an aerodynamic device. Background technique [0002] The traditional wing used for aircraft is an integral structure, which can only produce lift but not thrust under the action of pulling force or thrust produced by the engine, and the large lift of the wing with a small area can only be realized by increasing the speed; the traditional helicopter The main rotor depends on the rotor head to adjust the angle of attack of the blades and the waving state to adjust the direction of the lift. The structure is complex and the efficiency of generating lift is low. Traditional wings are not suitable for heavy-load low-speed flight, let alone vertical lift. Contents of the invention [0003] The purpose of the present invention is to overcome the above-mentioned deficiency of traditional wing, invents a kind of aerodynamic device. [0004] An aerodynamic device c...
