Embodiment Construction

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

[0020] like 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 frame ...

Abstract

The invention discloses an aircraft imitating a hummingbird flapping wing. The low-frequency swing of the wings of the aircraft provides sufficient force to enable the hummingbird aircraft to complete actions such as suspending, advancing and retreating. The force provided by only one motor makes the wings incite at the same time through the gear set and the connecting rod, and the two elastic rods are controlled by two steering gears. The change of the shape and position of the elastic rod changes the state of the two wings, making a pair of wings The size and direction of the resultant force generated can be controlled to realize the straight-line and direction-changing flight of the hummingbird aircraft. The hummingbird aircraft is powered by a lithium battery with high energy density. The battery and its flexible battery connecting rod can help the control system to balance the center of gravity, reduce system vibration, and make the system stable and reliable. The invention utilizes an uncomplicated structure to realize the biomimetic attitude flight of the small-mass aircraft, can realize the flight action stably and reliably, and contributes to the development of the biomimetic aircraft.

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 ...
