A device for conveniently adjusting thrust direction

Abstract

A device for conveniently adjusting the direction of thrust belongs to the technical field of aircraft and includes fins, propellers and supports. The fins are located above the propeller, and the fins include front fins, rear fins and wing shafts. The wing axis is parallel to the plane of rotation of the propeller. The front wing and the rear wing are respectively placed on the front and rear sides of the wing shaft, and the front wing and the rear wing can flexibly swing around the wing shaft under the action of external force. The power drives the propeller to rotate. Under the joint action of the propeller and the wings, the device will generate a large thrust that is convenient to adjust the direction and size. The size and direction of the thrust can be adjusted by adjusting the speed of the propeller and the front and rear wings. Adjust the angle with the horizontal plane. The device has small resistance, high efficiency, large lift-to-drag ratio, strong maneuverability, and is suitable for vertically lifting heavy-loaded low-speed aircraft.

Description

technical field [0001] A device for conveniently adjusting thrust direction belongs to the technical field of aircraft, and in particular relates to a thrust 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, invent a kind of device that conveniently adju...
