Translational flapping wing mechanism and orthopter and glider with translational flapping wing mechanism

Abstract

The invention discloses a translational flapping wing mechanism, an ornithopter with the translational flapping wing mechanism, and a glider. The translational flapping wing mechanism comprises a first linear simple harmonic motion mechanism for driving the front edge of a wing to do up-and-down simple harmonic motion and a second linear simple harmonic motion mechanism for driving the rear edge of the wing to do up-and-down simple harmonic motion, wherein phase difference exists between the up-and-down simple harmonic motion of the front edge of the wing and the up-and-down simple harmonic motion of the rear edge of the wing, so that the attack angle of the wing is changed during up-and-down translational motion of the wing. According to the translational flapping wing mechanism provided by the invention, the front edge of the wing and the rear edge of the wing do up-and-down simple harmonic motion respectively, the change of the displacement of the wing relative to an airframe along with time is closer to sine curve, the motion is soft, and phase difference exists between the motion, so the attack angle of the wing can be changed during up-and-down translational motion of the wing, and the translational flapping wing mechanism is suitable for being applied to a large-sized ornithopter.

Description

technical field [0001] The invention relates to a translational flapping-wing mechanism and an orthopter and a glider with the translational flapping-wing mechanism. Background technique [0002] In the field of international aviation, the research on orthopter has been very active in recent years. Many achievements have been made in the research of orthopter, most of which are orthopter with swinging wings. Value. Due to the rapid development of high-tech fields such as electronic computers, new composite materials, and control technologies, a new foundation has been laid for the development of orthopters. Fly faster and more energy-efficiently without relying on energy-hungry propellers and jet power. [0003] In China, a four-link flapping-wing mechanism is generally used, and the tail is controlled. There are already some pigeon-sized flapping-wing aircraft flying. The "big duck paw" single-piloted orthopter of the Aviation Research Institute of the University of Toro...

AI Technical Summary

Problems solved by technology

[0004] The four-link flapping-wing mechanism and the wire-controlled flapping-wing mechanism of the prior art are both swinging flapping wings, which are only suitable for micro and small flapping-wing aircraft, and are not suitable for use on large-scale flapping-wing aircraft.
