Device with convenience in thrust direction adjustment

Abstract

The invention provides a device with convenience in thrust direction adjustment and belongs to the technical field of aircrafts. The device comprises a vane, a propeller and a bracket, wherein the vane is located above the propeller and comprises a front vane, a back vane and a wing shaft which is parallel to the rotary plane of the propeller; the front vane and the back vane are arranged on the front side and the back side of the wing shaft respectively and can rotate flexibly around the wing shaft under the action of external force; the propeller is driven by power to rotate, the device can generate larger thrust with convenience in direction and magnitude adjustment under the combined action of the propeller and the vane, the magnitude and the direction of the thrust can be adjusted through adjustment of the rotational speed of the propeller and the included angle between each of the front vane and the back vane and the horizontal plane. The device has lower resistance, higher efficiency, higher lift-drag ratio and higher maneuverability and is applicable to VTOL (vertical take-off and landing) heavy-load low-speed aircrafts.

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...
