Double-wing type insect-like air vehicle

Abstract

The invention relates to a double-wing type insect-like air vehicle, belonging to the technical field of micro air vehicles. The double-wing type insect-like air vehicle comprises four wings, permanent magnets, spiral coils, a control module, an air vehicle body, four carapaces, L-shaped chests and flexible hinges, wherein the permanent magnets and the spiral coils are corresponding to the four wings, and the L-shaped chests and the flexible hinges are corresponding to the four carapaces; the four wings are respectively bonded at the B ends of the four carapaces; the spiral coils and iron cores are bonded on the surface of the L-shaped chest along the D end; the four permanent magnets are respectively bonded on the surface of the carapaces opposite to the spiral coils and the iron cores; the axial lines of the permanent magnets, the iron cores and the spiral coils are coincident; the four L-shaped chests are fixedly arranged in the air vehicle body; the flexible hinges are respectively connected with the L-shaped chests and the carapaces; and the control module is installed at the center of the air vehicle body and is respectively connected with the four spiral coils. In the invention, each wing is directly driven by the electromagnetic force of an electromagnetic driver, thus each wing has simple structure and can be controlled conveniently and flexibly; the change frequency and the acting direction of the driving force can be changed by changing the frequency, the time sequence and the amplitude value of exciting pulse; and the main structure of the air vehicle is processed by adopting the MEMS technology, thus the miniaturization of the air vehicle can be realized easily.

Description

technical field [0001] The invention relates to a device in the technical field of micro-aircraft, in particular to a biplane imitation aircraft. Background technique [0002] The flapping-wing micro-aircraft is a micro-aircraft that imitates the flight of birds or insects. It is a new type of aircraft developed in the 1990s. It has the characteristics of small size, light weight, low cost, and flexible flight. Bird-imitation and insect-imitation are two research models of flapping-wing micro-aircraft. The bird-imitation aircraft is larger in size and has a small wing vibration frequency; the insect-imitation aircraft is smaller in size and high in vibration frequency. The goal of studying flapping-wing micro-aircraft is to reduce the size of flapping-wing micro-aircraft as much as possible. [0003] At present, micro air vehicles can be divided into three categories according to the flight mode: fixed wing, rotary wing and flapping wing. When the wingspan is less than 1...
