Problems solved by technology

[0002] The efficiency of traditional propeller aircraft is low, and it is difficult to achieve short-distance take-off and landing; the lift device used in traditional flapping-wing aircraft is the traditional flapping-wing mechanism, which is driven by the crankshaft connecting rod, and the flapping wings flap up and down to generate thrust, which is more efficient. Low, high fatigue strength requirements for the flapping wing, the flapping wing is flexible, it is difficult to generate a large thrust, and it is difficult to vertically lift and hover in the air

Embodiment Construction

[0013] now attached figure 1 , attached figure 2 And attached image 3 The present invention is described by way of example: a kind of rotary flapping wing driving aircraft is made up of fuselage 1, landing gear, empennage 2, left wing 3, right wing 4 and control system. The left wing 3 and the right wing 4 have the same structure, and are arranged symmetrically on the left and right sides of the fuselage 1; the middle part of the left wing 3 has a rectangular hole in which a left-rotating flapping wing device is installed; the right wing 4 The same rectangular hole is also arranged in the middle part, and a symmetrical right-rotating flapping-wing device with the same structure as the left-rotating flapping-wing device is installed in this hole. The left-rotating flapping-wing device and the right-rotating flapping-wing device are independently driven by respective engines to provide thrust for the aircraft. The aircraft has high efficiency, is convenient for short-distan...

Abstract

The invention relates to a rotary flapping wing driving airplane which belongs to the technical field of aircrafts. The rotary flapping wing driving airplane is composed of a fuselage, landing gears, an empennage, a left wing, a right wing and a control system, wherein the structure of the left wing is the same as that of the right wing, the left wing and the right wing are symmetrically arranged on the left and right sides of the fuselage, two same rectangular holes are formed in the middles of the left wing and the right wing, a left rotary flapping wing device and a right rotary flapping wing device are respectively and symmetrically installed in the two holes, and the two devices are independently driven by respective engines, so as to provide thrust for the airplane. The airplane can take off and land with a short distance and can vertically lift and hover.

Description

technical field [0001] A rotary flapping-wing driven aircraft belongs to the technical field of aircraft, in particular to a flapping-wing driven aircraft. Background technique [0002] The efficiency of traditional propeller aircraft is low, and it is difficult to achieve short-distance take-off and landing; the lift device used in traditional flapping-wing aircraft is the traditional flapping-wing mechanism, which is driven by the crankshaft connecting rod, and the flapping wings flap up and down to generate thrust, which is more efficient. Low, the fatigue strength requirements of the flapping wing are high, the flapping wing is flexible, it is difficult to generate a large thrust, and it is difficult to vertically lift and hover in the air. Contents of the invention [0003] In order to overcome the deficiencies of the above-mentioned traditional aircraft, the present invention provides a kind of rotary flapping wing drive aircraft, the flapping wing makes the rotation...
