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 turbine blade comprising: a first section;a second section adjacent said first section; anda hydraulic lift system, wherein at least one of said first section and said second section comprises a skin segment and a network of support members disposed within said skin segment, said network of support members configured for expansion, said hydraulic lift system configured to expand said network of support members to an expanded state, said network of support members comprising a telescopic spine, said telescopic spine comprising a first spine segment, a second spine segment, and a locking mechanism configured to permanently lock said first spine segment relative to said second spine segment after said network of support members is in the expanded state such that said network of support members cannot retract said network of support members remains in a state of permanent expansion; and wherein a filler material is injected into an interior space therefore embedding said support members such that the at least one of said first section and said second section is permanently fixed in its expanded state. 2. The wind turbine blade in accordance with claim 1, wherein said first section comprises a base flange configured for attaching said first section to said second section. 3. The wind turbine blade in accordance with claim 1, wherein said network of support members further comprises a plurality of airfoil-shaped ribs connected to said spine. 4. The wind turbine blade in accordance with claim 1, wherein said at least one of said first section and said second section comprises said foam filler material between said network of support members when in the expanded state and said skin segment. 5. The wind turbine blade in accordance with claim 4, wherein said at least one of said first section and said second section comprises a port for injecting said foam filer material. 6. The wind turbine blade in accordance with claim 1, wherein said locking mechanism comprises an aperture defined by said first spine segment and a spring-loaded detent disposed on said second spine segment, and wherein said locking mechanism locks said first spine segment relative to said second spine segment by insertion of said spring-loaded detent into said aperture. 7. The wind turbine comprising: a tower; anda rotor mounted on said tower, wherein said rotor comprises a hub and a plurality of blades extending from said hub, one of said blades comprising: a first section;a second section adjacent said first section; anda hydraulic lift system, wherein at least one of said first section and said second section comprises a skin segment and a network of support members disposed within said skin segment, said network of support members configured for expansion, said hydraulic lift system configured to expand said network of support members to an expanded state, said network of support members comprising a telescopic spine, said telescopic spine comprising a first spine segment, a second spine segment, and a locking mechanism configured to permanently lock said first spine segment relative to said second spine segment after said network of support members is in the expanded state such that said network of support members cannot retract said network of support members remains in a state of permanent expansion; and wherein a filler material is injected into an interior space therefore embedding said support members such that the at least one of said first section and said second section is permanently fixed in its expanded state. 8. The wind turbine in accordance with claim 7, wherein said first section comprises a base flange configured for attaching said first section to said second section. 9. The wind turbine in accordance with claim 7, wherein said network of support members further comprises a plurality of airfoil-shaped ribs connected to said spine. 10. The wand turbine in accordance with claim 7, wherein said at least one of said first section and said second section comprises said foam filler material between said network of support members when in the expanded state and said skin segment. 11. The wind turbine in accordance with claim 10, wherein said at least on of said first section and said second section comprises a port for injecting said foam filler material. 12. The wind turbine in accordance with claim 7, wherein said locking mechanism comprises an aperture defined by said first spine segment and a spring-loaded detent disposed on said second spine second, and wherein said locking mechanism locks said first spine segment relative to said second spine segment by insertion of said spring-loaded detent into said aperture. 13. A method of assembling a wind turbine blade, said method comprising: providing a collapsed network of support members for a section of the blade, the network of supports including a telescopically expandable spine, the telescopically expandable spine including a first spine segment, a second spine segment, and a locking mechanism configured to permanently lock the first spine segment relative to the second spine segment such that the network of support members cannot retract after expansion of the telescopically expandable spine to an expanded state using a hydraulic lift system; andattaching a skin segment to the network of support members such that the network of support members is disposed within the skin segment, wherein the network of support members is configured for expansion to tension the skin segment such that an interior space is defined between the skin segment and the expanded network of support members said network of support members remains in a state of permanent expansion; and wherein a filler material is injected into the interior space therefore embedding said support members such that the at least one of said first spine segment and said second spine segment is permanently fixed in its expanded state. 14. The method in accordance with claim 13, wherein the network of support members includes a plurality of ribs connected to the telescopically expandable spine, said method comprising fixedly attaching the skin segment to each of the ribs to configure the skin segment for incremental tensioning upon expansion of the telescopically expandable spine using the hydraulic lift system. 15. The method in accordance with claim 13, further comprising providing the skin segment as a foldable, fluid impermeable material having a silicone-coated, glass-fiber fabric. 16. The method in accordance with claim 13, further comprising providing a hollow second section of the blade, and configuring the network of support members to be stored within the hollow second section when the network is collapsed.
