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.

A rotor blade assembly for a wind turbine having a rigid root insert is disclosed. The rotor blade assembly includes a blade root section having an end face with a substantially annular cross-section defined by an outer sidewall surface and an inner sidewall surface. The end face is configured to attach the rotor blade assembly to a hub. The rotor blade assembly includes a radial bore hole provided a predetermined span-wise distance from the end face and extending between the sidewall surfaces and a longitudinal bore hole provided between the sidewall surfaces and extending from the end face to the radial bore hole. The rigid root insert is disposed within the longitudinal bore hole and extends from the end face to the radial bore hole. As such, the rigid root insert is configured to increase the stiffness of the blade root section when the rotor blade assembly is attached to the hub with bolts that extend into and through the radial bore hole and the longitudinal bore hole.

The rotor blade assembly of claim 1, wherein the cross-bolt component comprises an internal female threaded portion. 3. The rotor blade assembly of claim 2, further comprising a bolt component comprising a male threaded portion, wherein the bolt component extends into and through the rigid root insert and at least partially through the cross-bolt component such that the male threaded portion engages the female threaded portion so as to form a T-bolt connection. 4. The rotor blade assembly as in claim 3, wherein the bolt component further comprises a nut component and a washer component configured to provide a predetermined preload to the bolt component so as to compress the rigid root insert when in an assembled state. 5. The rotor blade assembly as in claim 1, wherein the rigid root insert comprises a length substantially equal to a length of the longitudinal bore hole so as to increase the stiffness of the blade root section when the rotor blade assembly is in an assembled state. 6. The rotor blade assembly of claim 4, further comprising a pitch bearing configured between the end face of the blade root section and the hub, Wherein the rigid root insert compresses between the pitch bearing and the cross-bolt component when in an assembled state. 7. The rotor blade assembly of claim 1, further comprising a plurality of longitudinal bore holes and a plurality of radial bore holes, wherein the plurality of longitudinal bore holes and the plurality of radial bore holes are circumferentially-spaced in the blade root section, and wherein each of the longitudinal bore holes aligns with one of the radial bore holes to form a T-configuration. 8. The rotor blade assembly of claim 7, further comprising a plurality of rigid root inserts disposed within the plurality of longitudinal bore holes. 9. The rotor blade assembly of claim 6, further comprising a plurality of cross-bolt components disposed within the plurality of radial holes and a plurality of bolt components disposed within the plurality of rigid root inserts, wherein each cross-bolt component comprises a female threaded portion and each bolt component comprises a male threaded portion, and wherein each male threaded portion engages one of the female threaded portions so as to form a T-bolt connection. 10. The rotor blade assembly of claim 1, wherein the rigid root insert comprises a hollow bore having a smooth inner surface. 11. The rotor blade assembly of claim 1, wherein the rigid root insert comprises a cross-sectional shape, wherein the cross-sectional shape is one of a circle, annular shape, asymmetrical shape, square, oval, trapezoid, rectangle, triangle, or a portion thereof. 12. The rotor blade assembly of claim 1, wherein the end face of the root section is generally flush with an end portion of the rigid root insert. 13. A wind turbine, comprising: a tower;a nacelle configured atop the tower; and,a rotor coupled to the nacelle, the rotor comprising a rotatable hub and at least rotor blade comprising a rotor blade assembly, the rotor blade assembly comprising:a blade root section comprising an end face having a substantially annular cross-section defined by an outer sidewall surface and an inner sidewall surface, the end face configured to attach the rotor blade assembly to the rotatable hub;a plurality of radial bore holes provided at a predetermined span-wise distance from the end face and extending between the sidewall surfaces;a cross-bolt component disposed within each of the plurality of radial bore holes;a plurality of longitudinal bore holes provided between the sidewall surfaces and extending from the end face to the radial bore hole, wherein each of the longitudinal bore holes aligns with one of the radial bore holes to form a T-configuration; and,a plurality of rigid root inserts, each rigid root insert disposed within one of the plurality of longitudinal bore holes and extending from the end face to one of the plurality of the cross-bolt components, the plurality of rigid root inserts being flush with the end face of the blade root section and abutting against the cross-bolt components, wherein the plurality of rigid root inserts are configured to increase the stiffness of the blade root section when the rotor blade assembly is attached to the hub with bolts that extend into and through the radial bore hole and the longitudinal bore hole. 14.
