생체 모방 날갯짓 비행체 개발에 필요한 기술적 이슈들

This paper addresses key technical issues in the development of bio-inspired flapping-wing aircrafts. 350 million years of adaptation of nature's flyers deliver us the insights for optimal solutions of "How to make artificial flappers fly". However the complexities of flapping-wing motions and aerodynamics cause the difficulties of systematic development of flapping-wing aircrafts. Even though some studies have been performed for the hypothesis of high lift mechanism of flapping-wings and the principles of nature's flyers' flight principle, we do not have well-established design procedures to assemble a stable and controllable flapping-wing aircraft. Hereby we introduce some key technology issues such as optimal flapping-wing and flight controller designs to develop artificial flappers.
