Double-wing ornithopter provided with controllable buoyancy wings and power wings and operation method of double-wing ornithopter

Abstract

The invention discloses an ornithopter, particularly relates to an operation method of the ornithopter, aims to provide an ornithopter with little power loss, large flight distance and high speed, and provides an operation method of the ornithopter which is simple to operate, high in flight efficiency and little in power loss. The ornithopter comprises a body (1), buoyancy wings (2), power wings (3), a flapping wing driving device, an empennage and a control system, wherein a plurality of wing holes (5) are formed in the buoyancy wings (2) and the power wings (3), and opening and closing devices are arranged on the buoyancy wings (2) and the power wings (3). According to the operation method, the wing holes (5) in the power wings (3) are closed, and the wing holes (5) in the buoyancy wings (2) are opened simultaneously; the wing holes (5) in the power wings (3) are opened, and the wing holes (5) in the buoyancy wings (2) are closed simultaneously, and periodic cycling is performed. The ornithopter and the operation method of the ornithopter are applied to the technical field of aircrafts.

Description

technical field [0001] The invention relates to an aircraft, in particular to a flapping-wing aircraft with controllable buoyancy wings and power wings, and also relates to an operation method of the flapping-wing aircraft. Background technique [0002] In order to realize the flying dream of human beings, people began to study aircraft in the early days, starting from the flapping wing aircraft, but the initial realization was obtained from the fixed wing aircraft. Although fixed-wing aircraft can already send humans into the blue sky, Flapping Dream is still working hard. The orthopter aircraft refers to an aircraft that generates lift and forward force through the active movement of the wings like a bird, also known as the thopter. Because the flapping-wing aircraft has many advantages, such as the flapping-wing aircraft does not need a runway to take off and land vertically, the power system and the control system are integrated, and the mechanical efficiency is higher ...

AI Technical Summary

Problems solved by technology

[0007] But there are still problems and shortcomings in the above-mentioned flapping wing aircraft technology, such as: 1, because its aerodynamics just imitates the flight of birds purely, under the existing raw materials and technical conditions, it is impossible to design an efficient aircraft that makes the aircraft wingspan Too large, the buoyancy of the flight work and the forward flight force are inefficient, and the power energy consumption is too large, which is not conducive to the weight-bearing and long-distance and relatively high-speed flight; 2. The limitation of human muscle kinetic energy is ignored, and no auxiliary power is added or pure mechanical power is used. so that the current flapping-wing aircraft cannot become a practical aircraft in the true sense under the condition of heavy load and long-distance relatively high-speed flight
