AI Technical Summary

Problems solved by technology

For thousands of years, human beings have continued to explore, and many ancestors have sacrificed their precious lives. However, flapping is a behavior of organisms that have evolved through tens of millions of years, and it is a very complex multidimensional movement. Artificially imitated wings are often heavy, inefficient, and difficult to manipulate
Therefore, human society has not yet invented a practical flapping-wing aircraft, which has become an unsolved problem in the history of world aviation.

Embodiment 1

[0018] see figure 1 , figure 2 , as shown in the legend therein, a flapping-wing aircraft includes a fuselage 1, a wing 2, an empennage 4 and a bicycle power unit 5, and the wing 2 includes two symmetrically arranged on both sides of the fuselage 1. Fixed wing 21, two rotary flapping wings 22 respectively arranged on the outer ends of said fixed wing 21, and two flapping wings which are arranged on said fixed wing 21 and control said rotary flapping wings 22 to rotate Wing Controller 3.

[0019] The flapping wing controller 3 includes a driving shaft 31 connected to the bicycle power unit 5, a driving gear 32 (35 teeth) sleeved on the driving shaft 31, arranged in parallel with the driving shaft 31 A driven shaft 33, a driven gear 34 (35 teeth) sleeved at one end of the driven shaft 33 and meshed with the driving gear 31, and a transmission mechanism disposed at the other end of the driven shaft 330.

[0020] The transmission mechanism includes a small bevel gear 35 (21 te...

Embodiment 2

[0025] see figure 1 , image 3 , as shown in the legend therein, a flapping-wing aircraft includes a fuselage 1, a wing 2, an empennage 4 and a bicycle power unit 5, and the wing 2 includes two symmetrically arranged on both sides of the fuselage 1. Fixed wing 21, two rotary flapping wings 22 respectively arranged on the outer ends of said fixed wing 21, and two flapping wings which are arranged on said fixed wing 21 and control said rotary flapping wings 22 to rotate Wing Controller 3.

[0026] The flapping wing controller 3 includes a driving shaft 310 connected to the bicycle power unit 5, a driving gear 320 (35 teeth) sleeved on the driving shaft 310, arranged in parallel with the driving shaft 310 A driven shaft 330, a driven gear 340 (35 teeth) sleeved at one end of the driven shaft 330 and meshed with the driving gear 310, and a transmission mechanism disposed at the other end of the driven shaft 330.

[0027] The transmission mechanism includes a small bevel gear 35...

Embodiment 3

[0032] The rest is the same as the first embodiment, the difference is that the power unit is an electric motor power unit.

Abstract

The invention discloses a flapping-wing aircraft which comprises an aircraft body, aircraft wings, an empennage and a power device. The flapping-wing aircraft is characterized in that the aircraft wings comprise fixed aircraft wings arranged on two sides of the aircraft body symmetrically, and flapping-wing mechanisms arranged on the front portions or on the rear portions of the fixed aircraft wings. The flapping-wing mechanisms comprise rotating flapping wings and flapping-wing controllers for controlling the rotating flapping wings to rotate. The flapping-wing aircraft is simple in structure and good in practicality.

Description

technical field [0001] The invention relates to a flapping wing aircraft. Background technique [0002] An orthopter is a flying machine that imitates the flight of birds or insects. The flapping-wing aircraft can fly vertically with flapping wings, and can also fly forward with flapping wings. It has the advantages of flexible flight and low energy consumption. For thousands of years, human beings have continued to explore, and many ancestors have sacrificed their precious lives. However, flapping is a behavior of organisms that have evolved through tens of millions of years, and it is a very complex multidimensional movement. Artificially imitated wings are often heavy, inefficient, and difficult to manipulate. Therefore, human society has not yet invented a practical flapping-wing aircraft, which has become an unsolved problem in the history of world aviation. Contents of the invention [0003] The invention provides a flapping-wing aircraft with simple mechanism and...
