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.

The invention relates to a rotational device that is to be used in a fluid in order to generate power from the moving stream of a fluid or to convert energy into a motion of a fluid. Said rotational device comprises main rotating means which is fixedly connected to a central rotary shaft of the rotational device, one or several rotational surfaces which are mounted on the main rotating means so as to be rotatable about rotational surface rotary shafts spaced away from the rotary shaft such that the main rotating means are able to perform a rotational motion about the central rotary shaft by means of at least one rotational surface, the rotational surface rotary shafts extending parallel to the rotary shaft of the main body. A device is provided which adjusts an angle of the rotational surface relative to the direction of flow of the fluid in such way that the buoyancy principle is maintained on the rotational surface.
