연합인증

연합인증 가입 기관의 연구자들은 소속기관의 인증정보(ID와 암호)를 이용해 다른 대학, 연구기관, 서비스 공급자의 다양한 온라인 자원과 연구 데이터를 이용할 수 있습니다.

이는 여행자가 자국에서 발행 받은 여권으로 세계 각국을 자유롭게 여행할 수 있는 것과 같습니다.

연합인증으로 이용이 가능한 서비스는 NTIS, DataON, Edison, Kafe, Webinar 등이 있습니다.

한번의 인증절차만으로 연합인증 가입 서비스에 추가 로그인 없이 이용이 가능합니다.

다만, 연합인증을 위해서는 최초 1회만 인증 절차가 필요합니다. (회원이 아닐 경우 회원 가입이 필요합니다.)

연합인증 절차는 다음과 같습니다.

최초이용시에는
ScienceON에 로그인 → 연합인증 서비스 접속 → 로그인 (본인 확인 또는 회원가입) → 서비스 이용

그 이후에는
ScienceON 로그인 → 연합인증 서비스 접속 → 서비스 이용

연합인증을 활용하시면 KISTI가 제공하는 다양한 서비스를 편리하게 이용하실 수 있습니다.

Abstract AI-Helper 아이콘AI-Helper

Using the more common conventional chordwise aerodynamic approach, flapping a flat plate wing with zero degree chordwise pitch angle of attack and no relative wind should not produce lift. However, in hover, with no forward relative velocity and zero degree chordwise pitch angle of attack, flapping ...

문제 정의

  • However, most of research tried to show the average lift or thrust of flapping cycle in various flapping frequencies, wing planforms and stream velocities, not the instantaneous force variation of flapping motion from the beginning of the downstroke to the end of the upstroke^1'21. Therefore, this research measured the instantaneous force variation of pure flapping cycle. Those result could effect to design MAV operated by flapping motion.

가설 설정

  • (1) At the beginning of the downstroke, the total lift force is a positive lift force. The total lift force increases until a certain point in the downstrake and peaks before the middle of the downstroke.
  • (3) The flapping wings produce another small peak in force almost at the end of the downstroke.
