Wing framework of imitation pterosaur flapping-wing aircraft

Abstract

The invention discloses a wing framework of an imitation pterosaur flapping-wing aircraft. The wing framework comprises four movable arms, namely a main movable arm, a second movable arm, a third movable arm and a fourth movable arm, wherein the end part of the main movable arm is connected with a main steering engine which controls the main movable arm to swing, the main movable arm and the second movable arm are connected with each other through a secondary steering engine, the second movable arm and the third movable arm are connected with each other through a tertiary steering engine, the third movable arm and the fourth movable arm are connected with each other through a quaternary steering engine, and the main steering engine, the secondary steering engine, the tertiary steering engine and the quaternary steering engine are respectively and internally provided with a driving motor. The wing framework is covered with a thin film wing and can be used as a wing of the flapping-wing aircraft. The framework is designed by imitating a bone structure of a pterosaur; and compared with the wing framework of an imitation bird flapping-wing aircraft, the wing framework is simple in mechanical structure and relatively low in cost, and can increase the lift coefficient and reduce the resistance coefficient.

Description

technical field [0001] The invention relates to a flapper, in particular to a wing skeleton of a pterosaur-like flapper. Background technique [0002] Scientists have developed a robot bird that can simulate the flight of birds. This robotic bird can take off, fly and land autonomously. Its wings can not only flap up and down, but also twist at specific angles, the robot bird has extraordinary aerodynamic performance and agility. The robot bird can be controlled by a radio walkie-talkie, and if switched to automatic mode, the robot bird can also fly in the air by itself. It weighs only 450 grams and is able to move its tail sideways and turn its head. Inside its body are two rotating wheels that control the up and down beating of its wings. The two rotating wheels, similar to the wheels of a train pulled by a steam locomotive, are connected to a drawbar and turn to provide power for the robotic bird to flap its wings. The wing angle of the robotic bird can be adjusted b...
