Four-wing flapping-wing air vehicle capable of adjusting attack angle

Abstract

The invention discloses a four-wing flapping-wing air vehicle capable of adjusting an attack angle. The four-wing flapping-wing air vehicle comprises a vehicle body, wing devices, a run-up device, a motor and a battery, the run-up device is mounted on the lower side of the body; the four sets of wing devices are installed on the two sides of the fuselage, the wing devices and the run-up device aredriven by motors, the multiple motors are powered by batteries, and an auxiliary lift device is arranged above the top of the fuselage. The wing device adopts a flapping wing form and simulates birdflight, the four groups of wings can effectively improve the flight stability and are combined with the rotor wings on the basis, the rotor wing blades are driven to rotate while the driving mechanismflaps, the rotation directions of the blades are the same during downward flapping and rising, continuous and stable lift force is provided, stable flight of the aircraft is guaranteed, and the flight efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of aircraft, and more specifically relates to a four-wing flapping-wing aircraft capable of adjusting the angle of attack. Background technique [0002] At present, insects, birds, and bats that can fly in nature all use flapping wings to fly, which has the characteristics of high maneuverability and low energy consumption. The flapping-wing aircraft is different from the fixed-wing aircraft and the rotary-wing aircraft. It is an aircraft that adopts the flying mode of insects, birds, and bats. [0003] However, due to the more complicated flight movements of birds. There are many in the prior art, most of which simply imitate the up and down swing of the wings of birds without the expansion and contraction of wings like birds, and can not independently control the left and right wings, so the flight efficiency is low and the maneuverability is quite limited. Therefore, it is necessary to provide a flappin...
