Description

Technical Field

[0001] The present invention relates to a highly biomimetic bird flapping-wing aircraft driven by a power system and its flight operation method. Background Technology

[0003] This invention is a highly realistic, manually piloted, powered aircraft that simulates bird flapping flight. The aircraft uses a power system to drive the corresponding wings (bionic wings) on both sides of the flapping-wing aircraft to move up and down, generating upward flight force. Under suitable weather conditions, it can be freely controlled by humans for flight. It can serve as a primary means of low-altitude transportation, a sightseeing vehicle for tourism, and can also assist in pesticide application for pest control, forest fire prevention, urban air traffic monitoring, and national defense. Summary of the Invention

[0004] This flapping-wing aircraft combines the ancient flapping-wing aircraft with modern engines or motors, including but not limited to other power sources. It is controlled according to the operator's subjective will to achieve manually piloted flight maneuvers, allowing people to fly freely in the sky like birds.

[0005] The aircraft has a streamlined shell resembling a bird, a streamlined body composed of a spine-like keel and ribs, an adjustable head and tail, symmetrical wings on both sides of the body that resemble bird wings, a cockpit on the underside of the body, and an attached landing gear.

[0006] The bionic body is wide in the middle and gradually narrows at both ends, and is supported by a skeleton of evenly distributed hollow tubular structures, including but not limited to metal or other materials. The overall body outline is very similar to that of a bird, with the front and back being flattened cones that are inverted. The central part of the body has the largest cross-section and is fully enclosed, while the other parts are gradually semi-enclosed, which facilitates the bending or straightening of the body.

[0007] The outer surface of the body, which is supported by the entire skeletal structure, is made of lightweight and tough materials, including but not limited to carbon fiber, carbon steel, bamboo fiber, and other mixtures. The subcutaneous layer is lined with inflatable air bladders and ropes that connect to the skeletal structure for support. The interior contains systems including but not limited to power systems, transmission systems, mechanical control systems, electronic navigation, and electronic information transmission and control systems.

[0008] This biomimetic ornithopter mimics the flight principle of birds. By manually controlling the up-and-down flapping of the wings on both sides of the body to generate power, controlling the head movement to control the direction of flight, and controlling the tail to control the direction of flight and the amount of air resistance, the ornithopter can fly freely in the air through the coordinated action of the head, tail and wings, thus realizing the dream of mankind to fly freely in the sky.

[0009] The control handles in the cockpit include, but are not limited to, controlling the power of the power system, the speed and frequency of the rise and fall of the wings, the direction of the nose and tail of the aircraft, and the balance and tilt angle of the aircraft, so that people can fly or land freely in the air.

[0010] The wings on both sides can extend or retract, rise or fall according to the pilot's control actions. During takeoff or landing, the frequency and amplitude of wing flapping are very large. When entering the air flight phase, the flapping force, frequency and amplitude of the wings are relatively reduced or extended for gliding. When rotating, the outer wing may flap with greater force, frequency and amplitude than the inner wing, thus achieving a rotation.

[0011] The wings on both sides are powered primarily by engines or electric motors. Power is transmitted directly or indirectly to the innermost tip of the wing via gears or chains, causing it to move in an arc up and down motion. Simultaneously, the upper and lower skins of the wings are pulled by steel wires or strong rubber bands, which in turn cause the wings to move up and down. When pulled, the bionic feathers on the wings separate when the fuselage rises and close when it descends. When the wings rise, the gaps created by the separation of the feathers reduce air resistance, making it easy to lift the wings. When the wings fall, the closed feathers form a fan shape, generating downward pressure that propels the fuselage upward. This cycle repeats, easily lifting the wings and generating power when the feathers close into a fan shape during downward flapping, greatly improving the efficiency of useful work during flight.

[0012] During the flight of an ornithopter, the aircraft controls the left or right twist by swinging the tail fin left or right; the aircraft controls the speed and angle of descent by pressing down the tail fin, increasing or decreasing drag to decelerate or accelerate; when the tail fin is kept straight, aerodynamics is used to save kinetic energy, allowing the aircraft to fly level or glide in the air.

[0013] The nose of an ornithopter can rotate up, down, left, and right to control the corresponding rotational movements of the aircraft. The rotation of the nose and tail works in tandem to control the coordinated rotation of the entire body. All movements are controlled by the cockpit control stick. Through the coordination and control of the power control and the control stick, the pilot can control the flight behavior, enabling humans to fly freely in the air like birds.

[0019] A data information platform is arranged in the cockpit, which displays various power, space, environment and other information during flight in real time, including flight altitude, flight speed, flight angle, direction and intensity of air flow; there are control handles, foot pedals and seats inside. The control handle rotates up, down, left and right to control the rotation and direction of the head and tail; the foot pedal controls the power or electricity of the engine or motor, so as to control the speed and frequency of the wings flapping up and down; the seat fixes the body part, and there is a close connection between the seat and the handle. The lower end of the seat and the biomimetic body are connected by a universal joint. By controlling the front, back, left and right swinging of the handle and the seat, the biomimetic body can be made to swing up, down, left and right and tilt and other actions.
