Abstract

Abstract:

An active morphing flapping wing can mimic the complex movement of a flying bird's wings. In order to understand the aerodynamics of the active morphing wing ornithopter, the bird's bone structure as well as the laws of motion of its wing and tail are studied, and an active morphing wing ornithopter is designed and built based on robotics. The laws of motion of the ornithopter are presented, a control system is designed and built. Wind tunnel tests of the ornithopter are performed in a low-speed wind tunnel. The lift and thrust characteristics are studied. Furthermore, the influence of wind velocity, flapping frequency, amplitude and stretch phase on lift and thrust is investigated. A conventional flapping wing is tested for contrast. The test result shows that the active morphing wing can significantly increase the lift and enhance the ability of the ornithopter to adapt to various flight statuses.

Key words: active morphing, flapping wing, ornithopter, imitation of a bird, laws of motion, wind tunnel test, aerodynamic characteristic
