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 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.

A vertical axis omni-wind turbine having a wind sail centrally mounted to a turbine drive shaft, the wind sail consisting of three generally identical vanes paced 120 degrees apart. The vanes each have a generally concave surface for capturing impinging wind thrust with an opposite generally convex surface to provide minimal wind resistance. The resulting disparate wind resistance causes a stronger reaction on the concave side of a vane which in turn provides rotation about the vertical oriented drive shaft. The turbine has omni-wind characteristics in t...

1. Apparatus for utilizing wind force to drive a rotatable turbine drive output shaft, said apparatus comprising: a longitudinally extending wind sail having three generally identical vane members adjoined at a central portion and extending from said central portion spaced 120 degrees apart;a longitudinally extending turbine drive shaft;said central portion of said wind sail configured for receiving said turbine drive shaft for centrally mounting of said wind sail on said turbine drive shaft, said vane members merging to include said central portion therebetween;said vane members are adjoined to said central portion, each vane member having a convex rear surface defining air output holes and a concave front surface defining a plurality of grooves running in generally parallel horizontal lines pointing toward said turbine drive shaft and capturing impinging airflow, each groove including an air exit port located on each groove proximate said turbine drive shaft for exhausting said captured impinging airflow through each said vane and onto the concave front surface of a following vane, each air exit port being continuous with a corresponding air output hole defined by the convex rear surface,said vane members extending from said central portion in an identical manner such that in rotation when a first vane member presents a concave front surface to impinging wind, each of subsequent vane members likewise presents a concave front surface to impinging wind; andeach said vane member extends from said central portion in a curved scimitar-like configuration. 2. The apparatus of claim 1 wherein the concave front and convex rear surfaces of said vanes constantly provide concavity to impinging wind to initiate and maintain rotation of the turbine shaft regardless of wind direction. 3. The apparatus of claim 1 wherein each of the convex rear surface includes wind disrupters configured to minimize drag on rotation about said turbine drive shaft, said disrupters including multitudinous indentations in said convex rear surface. 4. The apparatus of claim 1 wherein each said vane further includes at its outer edge a torque converter comprising an airfoil having an extension for supporting said airfoil, said extension pivotally mounted at one end to said vane and at another end pivotally mounted to said airfoil. 5. A wind sail responsive to wind force to drive a rotatable turbine drive shaft, said wind sail comprising: a three vane member with each vane having an arched front concave surface portion, and an arched reverse convex surface portion, each said vane member adjoined at a centrally located portion and extending in identical manner from said centrally located portion spaced 120 degrees apart; each front concave surface portion surface defining a plurality of grooves running in generally parallel horizontal lines; each groove including an air exit port located on each said groove proximate said turbine drive shaft for exhausting captured impinging airflow through each said vane and onto the front concave surface portion of a following vane in rotation when a first vane member presents a concave front surface portion to impinging wind, each subsequent vane members likewise presents a concave front surface portion to the wind;each said vane member extends from said centrally located portions with a generally curved shaped configuration, rear convex surface portion defining air output holes and including wind disrupters configured to minimize drag on rotation about said turbine drive shaft, said disrupters including multitudinous indentations, said air output holes being continuous with corresponding air exit ports of the plurality of grooves; andwherein the combination of the front concave and rear convex surface portions of said vanes provides a sufficient concavity to impinging wind to initiate and maintain rotation of said turbine drive shaft regardless of wind direction. 6. The wind sail of claim 5 wherein each of the front concave surface portion includes a plurality of open grooves running in generally parallel horizontal lines from an outer edge of said vane toward said turbine drive shaft, said grooves capturing impinging airflow and channeling it inwardly toward said turbine drive shaft. 7. The wind sail of claim 5 each said vane member extends from said centrally located portions with a generally scimitar-shaped configuration. 8. Apparatus responsive to wind force for driving a rotatable turbine drive shaft, said apparatus comprising: an impeller responsive to wind for driving the rotatable turbine drive shaft;said impeller includes a central portion having three identical adjoining vane members extending from said central portion in vertical alignment spaced 120 degrees apart, each said vane member having a front arched concave surface and a rear arched convex surface,each said front concave surface operating to respond to said wind to force rotation of said rotatable turbine drive shaft while said rear convex surface offers minimal resistance to rotation of said shaft;the rear arched convex surface includes wind disrupters configured to minimize drag on rotation about said turbine drive shaft, said disrupters including multitudinous indentations in said rear convex surface; andeach said vane member further includes a pivoting torque converter spaced from an outer edge of the vane member, the torque converter comprising an airfoil, an extension for supporting said airfoil pivotally mounted at one end of said vane member and pivotally mounted to said airfoil at another end,wherein the combination of the vane members and said central portion is configured to consistently present a sufficient concavity to impinging wind to provide self-starting omni-wind operation. 9. The apparatus of claim 8 wherein each front arched concave surface includes a plurality of open grooves running in generally parallel horizontal lines from the outer edge of said vane toward said turbine drive shaft, said grooves capturing impinging airflow and channeling it inwardly toward said rotatable turbine drive shaft. 10. The apparatus of claim 9 including an air exit port located on each said groove proximate said turbine drive shaft for exhausting said captured impinging airflow through each said vane member and onto the concave surface of a following vane member.
