Embodiment Construction

[0019] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0020] Such as figure 1 As shown, the present embodiment provides a hummingbird flapping aircraft, comprising a motor 1, a power transmission mechanism 2, a battery 4, a double steering gear mechanism 5, a frame 6 and a pair of wings 3; wherein, the frame 6 is a whole The aircraft provides an overall frame, the motor 1 is fixedly connected to the frame 6 to form a unified whole, a pair of wings 3 are symmetrically arranged on both sides of the frame 6, and are connected to the frame 6 through the wing root bushing 101; It is located below the transmission mechanism 2 and connected to the two battery connecting rods 603 below the frame 6, so that it is connected to the wings 3 in a clearance fit manner; the battery 4 is located below the double steering gear mechanism 5, and the battery 4 passes through two batteries The connecting rod 603 is fixed on the fra...

Abstract

The invention discloses a bionic hummingbird ornithopter. Low-frequency swinging of wings of the ornithopter is used for providing enough force so as to enable the bionic hummingbird ornithopter to complete actions such as suspension, advancing and retreating. Force provided only by one motor drives the wings to be flapped at the same time through a gear set and a connecting rod, two elastic rodsare controlled cooperatively through two steering engines, the state of the two wings is changed through changing of the forms and the positions of the elastic rods, so that the magnitude and the direction of resultant force generated by the pair of wings are controllable, and linear and variable-direction flying of the bionic hummingbird ornithopter is realized. The bionic hummingbird ornithopteradopts lithium batteries with the large energy density for power supply, the batteries and flexible battery connecting rods of the batteries can cooperatively control the system so as to balance thegravity center of the system and reduce system vibration, so that the system is stable and reliable. According to the bionic hummingbird ornithopter, the bionic attitude flight of the small-mass ornithopter is realized by utilizing an uncomplicated structure, the flying action can be stably and reliably realized, and the bionic hummingbird ornithopter promotes the development of bionic aircrafts.

Description

technical field [0001] The invention belongs to the field of bionic robots, in particular to a bionic hummingbird aircraft. Background technique [0002] At present, there are researches on bionic robots in foreign countries, but our country started late in this area, with few achievements and poor effects. The "swarm" type bionic ammunition is dedicated to realizing all-round, ultra-close-range, and precise combat. [0003] The size of the micro-aircraft is less than 20cm. It is a product of interdisciplinary research. It uses micro-electromechanical, bionics, encrypted wireless communication, bionic aerodynamics, flexible wings, guidance devices, and micro-control technology. It can imitate birds and fly autonomously. Cruising, target recognition autonomous decision-making and return data. Micro air vehicles include various types such as bird-like aircraft and insect-like aircraft, and this type of micro air vehicle is the easiest to develop into bionic ammunition. The ...
