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.

1. A wind power installation comprising: at least one rotor which can rotate about a vertical axis and, between two horizontal mounting planes, which are located one above the other and separated, a plurality of rotor blades, which are arranged distributed on a circumferential circle and can each pivot about a vertical pivoting axis extending between said two horizontal mounting planes, and whose pivoting range is bounded at both ends by a single stop, wherein the width of the rotor blades is less than ⅓ of the radius of the circumferential circle, whereby said mounting planes are formed by wheels which rotate about said vertical axis, and the at least one rotor is connected via a shaft to a generator unit. 2. The wind power installation as claimed in claim 1, wherein twelve or more rotor blades are arranged such that they can pivot on the circumferential circle of the rotor. 3. The wind power installation as claimed in claim 1, wherein the rotor blades are in the form of straijht blades. 4. The wind power installation as claimed in claim 3, wherein the rotor blades each have a leading edge and a trailing edge, and have a reduced thickness between the leading edge and the trailing edge. 5. The wind power installation as claimed in claim 4, wherein the pivoting axes of the rotor blades are arranged within the rotor blades and spaced at a distance near the leading edge. 6. The wind power installation as claimed in claim 4, wherein the pivoting axes of the rotor blades are arranged in the leading edges of the rotor blades. 7. The wind power installation as claimed in claim 1, wherein the pivoting range of the rotor blades begins from the radius vector of the circumferential circle which passes through the pivoting axis and is in each case limited to an angle in the range of 100°-115°. 8. The wind power installation as claimed in claim 7, wherein, in one limit position of the pivoting range, the rotor blades each include an angle of about 50° with the radius vector of the circumferential circle which passes through the pivoting axis, and, in the other limit position of the pivoting range, include an angle in the range of 150°-165°. 9. The wind power installation as claimed in claim 1, wherein the mounting planes are formed by spoked wheels which rotate about the axis. 10. The wind power installation as claimed in claim 1, wherein the wind power installation has a plurality of rotors which are arranged at different heights. 11. The wind power installation as claimed in claim 10, wherein the rotors are arranged one above the other and rotate about the same axis. 12. The wind power installation as claimed in claim 11, wherein the rotors can rotate independently of one another. 13. The wind power installation as claimed in claim 1, wherein the rotor blades have an aerodynamic cross-sectional profile with a pointed end and a round end. 14. The wind power installation as claimed in claim 13, wherein the aerodynamic cross-sectional profile is in the form of a stretched droplet. 15. The wind power installation as claimed in claim 1, wherein the rotor drives within said generator unit at least one compressor via a power transmission, the compressor sucks in air on the input side and is connected on the output side to a compressed-air reservoir, and wherein a turbine can be connected to the compressed-air reservoir and drives a generator in order to produce electricity. 16. The wind power installation as claimed in claim 15, wherein the rotor can be selectively connected to a plurality of compressors via power transmission. 17. The wind power installation as claimed in claim 15, wherein the compressed-air reservoir is incorporated in the ground, and forms the foundation of the wind power installation arranged above it. 18.
