Design And Analysis of Flapping Wing Aircraft Based on Crank Mechanism

Highlights in Science, Engineering and Technology
This paper is proposed a flapping wing aircraft based on the crank slider mechanism to solve the problems of the two flapping wing structures, such as synchronization and excessive local stress common to existing ornithopters. MATLAB is used to solve the equations to determine the dimensions of the individual components, and the 3D model is designed by

Design and Analysis of the Driving Mechanism of Multi-DOF Flapping Wing Aircrafts

Jixie chuandong, 2022
In order to improve the flight performance of flapping wing aircrafts，a multi-DOF flapping wing mechanism based on space four-bar mechanism is designed by referring to the flight motion characteristics of small and medium-sized birds. Firstly，a kinematic model of the flapping wing driving mechanism is established through kinematic analysis.
