Experiment-Based Optimization of Flapping Wing Kinematics
نویسندگان
چکیده
Optimization of flapping wing trajectory was explored using an experimental apparatus. A scaled-up hawkmoth (Manduca sexta) wing was fabricated and mounted to a three-degree of freedom flapping mechanism. The vertical force generated during flapping was measured using a load cell and the wing path was optimized to maximize the average vertical force. The mechanism design, control, and instrumentation, and the optimization approach are explained. The optimization results, including wing trajectories, are presented and further research topics are discussed.

Kinematics Optimization for a Flapping-wing Micro Air Vehicle
A flight-dynamics oriented simulation model of a flapping-wing Micro Air Vehicle (MAV) has been developed. This concept is based on flapping flight performed in nature by insects or hummingbirds. An optimization of the flapping kinematics of the wing has been led, in order to maximize the mean lift and thus the payload. A neural network has been designed to reproduce the function shape of the w...
