Bionic aircraft

Abstract

The invention discloses a bionic aircraft. Series parallelogram telescopic main wings (2, 3) are symmetrically assembled on the left and the right above a body (1), bidirectional parallel parallelogram telescopic flat tail wings (4) are assembled in back of the body (1), undercarriage shock absorbers (40, 41, 42) arranged in three points are assembled below the body (1), undercarriage wheels (5, 6, 7) are assembled at one end of each of the shock absorbers (40, 41, 42) respectively, a driving cabin (8) and a safety umbrella cabin (9) are assembled above the body (1), the driving cabin (8) is positioned in front of the safety umbrella cabin (9), a solid rocket jato (10) is assembled at the lower gravity center position of the body (1), and the central axis of the solid rocket jato (10) and the central axis of the body (1) form an included angle of 10 to 15 degrees downwards. A nozzle faces to the lower rear part, a nose (11) is assembled in front of the body (1), and a power transmission mechanism and an operating system are assembled in the body (1). Because of the adoption of a bionic technology, the aircraft can simulate various flying postures of birds; the amplitude and frequency modulation transmission mechanism is favorable for rising, landing and flying of the aircraft; by adopting human-machine hybrid power, the aircraft has no pollution; because of good folding property of main rings, the aircraft is convenient for transportation; and the aircraft can be used for sports, escape, downhill race, patrol and the like.

Description

1. Technical field [0001] The invention relates to a bionic aircraft in the aviation field. 2. Technical background [0002] Flying freely in the sky like a bird has been the pursuit of human beings since ancient times. According to legend, Lu Ban, the founder of my country's construction industry in ancient times, once made a wooden bird with a bamboo structure, which could fly in the sky for three consecutive days. Han Xin, a famous general in the Western Han Dynasty, once used a kite to carry out manned flights. Modern German engineer Lilienthal designed and manufactured a cordless kite, a glider, which has successfully carried out many manned flights. With the advancement of human science and technology, in 1903 AD, the Wright brothers of the United States installed an internal combustion engine on the glider and successfully carried out manned flight by means of propeller propulsion, thus creating a new era of human flight. [0003] In the past hundred years since the...

Problems solved by technology

[0004] So far, people have designed a variety of flapping-wing aircraft, but those that can take off into the air are only some better-designed models, and the time left in the air is also shorter, and can only fly for a few minutes, while the flapping-wing aircraft that can carry people So far, it has not appeared in the blue sky. The reason is: some manned flapping-wing aircraft, the design of the transmission system is too simple, such as using the arm to drive the flapping wing, obviously the strength of the human arm is not enough. The transmission system of the current model uses a crankshaft-connecting rod mechanism, so that the amplitude and frequency of the flapping of the wings are constant, and the lift generated is small. Rods, hydraulic devices, solenoid valves and various types of gears make the structure too complicated, increase the number of failure points, and also greatly increase the weight of the aircraft

[0005] Some flapping-wing aircraft use the driver to move the body to adjust the center of gravity of the aircraft, which is awkward to change the flight attitude

In addition, the main wings and tail wings of most flapping-wing aircraft cannot be extended or retracted, and the attitude during flight is not easy to control
