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.

초록

A nacelle for a gas turbine engine includes a upper and lower bifurcations, an inner diameter cowl and a first latch system. The inner diameter cowl extends between the upper and lower bifurcations and the first latch system is mounted on the inner diameter cowl. The first latch system is spaced along the inner diameter cowl between the upper and lower bifurcations.

1. A nacelle for a gas turbine engine, the nacelle comprising: an upper bifurcation;a lower bifurcation;an inner fixed structure extending between the upper and lower bifurcations, the inner fixed structure comprising first and second halves;an outer diameter cowl surrounding the first and second halves;a first latch system mounted on the first half of the inner fixed structure and axially disposed along the inner fixed structure between the upper and lower bifurcations, the first latch system having a first handle mounted within and pivotal to protrude from the first half of the inner fixed structure; anda second latch system mounted on the second half of the inner fixed structure and axially disposed along the inner fixed structure, the second latch system having a second handle mounted within and pivotal to protrude from the second half of the inner fixed structure;wherein the first latch system further includes: one or more latching mechanisms disposed toward a forward end of the first half of the inner fixed structure; andone or more linking members extending axially forward from the first handle, through the outer diameter cowl, and to the one or more latching mechanisms, such that the one or more linking members connect the first handle to the one or more latching mechanisms. 2. The nacelle of claim 1, wherein the first half of the inner fixed structure includes an aft area cowl and the first handle is mounted on the aft area cowl. 3. The nacelle of claim 1, wherein the first handle opens in a forward direction relative to the first half of the inner fixed structure. 4. The nacelle of claim 1, wherein the latching mechanism comprises pin latches that engage a case of the gas turbine engine. 5. The nacelle of claim 1, wherein the one or more linking members comprise push-pull cables. 6. A nacelle for a gas turbine engine, the nacelle comprising: a first door having a first half of an inner fixed structure disposed within an outer diameter cowl and connected to a first half of a lower bifurcation;a first latch system mounted on the first half of the inner fixed structure and axially disposed along the first half of the inner fixed structure from the lower bifurcation;a second door having a second half of the inner fixed structure disposed within the outer diameter cowl and connected to a second half of the lower bifurcation; anda second latch system mounted on the second half of the inner fixed structure and axially disposed along the second half of the inner fixed structure between the upper and lower bifurcations;wherein the first latch system comprises: a first handle mounted within and pivotal to protrude from the first half of the inner fixed structure;one or more latching mechanisms disposed toward a forward end of the first half of the inner fixed structure; andone or more linking members extending axially forward from the first handle, through the outer diameter cowl, and to the one or more latching mechanisms, such that the one or more linking members connect the first handle to the one or more latching mechanismswherein the second latch system comprises a second handle mounted within and pivotal to protrude from the second half of the inner fixed structure. 7. The nacelle of claim 6, wherein the first inner fixed structure includes an aft area cowl and the first handle is mounted on the aft area cowl. 8. The nacelle of claim 6, wherein the first handle opens in a forward direction relative to the first half of the inner fixed structure. 9. The nacelle of claim 6, wherein the latching mechanism comprises pin latches that engage a case of the gas turbine engine. 10. The nacelle of claim 6, wherein the one or more linking members comprise push-pull cables. 11. A gas turbine engine comprising: a case; anda nacelle latched to the case, the nacelle comprising: an upper bifurcation;a lower bifurcation;an inner fixed structure extending between the upper and lower bifurcations, the inner fixed structure comprising first and second halves;an outer diameter cowl surrounding the first and second halves;a first latch system mounted on the first half of the inner fixed structure and axially disposed along the inner fixed structure between the upper and lower bifurcations, the first latch system having a first handle mounted within and pivotal to protrude from the first half of the inner fixed structure; anda second latch system mounted on the second half of the inner fixed structure and axially disposed along the inner fixed structure, the second latch system having a second handle mounted within and pivotal to protrude from the second half of the inner fixed structurewherein the first latch system further includes: one or more latching mechanisms disposed toward a forward end of the first half of the inner fixed structure; andone or more linking members extending axially forward from the first handle, through the outer diameter cowl, and to the one or more latching mechanisms, such that the one or more linking members connect the first handle to the one or more latching mechanisms. 12.
