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 method of positioning landing gear of an airplane is provided that includes providing the landing gear including a shock strut, a truck beam operatively pivotally connected to the shock strut, first and second interconnected links operatively connected to the truck beam and a third link extending between the shock strut and the first and second links with the third link pivotally connected to the second link at a third pivot. When the landing gear is commanded to a lowered position, the third pivot is positioned in a first position to support a taxi mode, a take-off mode and a landing mode if the landing gear is operational and in a second position to support an alternate landing mode if the landing gear is not fully operational. When the landing gear is commanded to a raised position, the third pivot is in the second position to support a stow mode.

1. A method of positioning a truck beam of a landing gear of an airplane, the method comprising: providing a semi-levered landing gear mechanism comprising a plurality of links operably connected between a shock strut and the truck beam and a truck pitch actuation system, wherein providing the semi-levered landing gear mechanism comprises providing the shock strut so as to have an inner and an outer cylinder, providing the truck beam so as to be pivotally connected to the inner cylinder of the shock strut, providing a first link connected to the truck beam at a first pivot, a second link connected to the first link at a second pivot and a third link connected to the second link at a third pivot and connected to the outer cylinder at a fourth pivot, and providing the truck pitch actuation system so as to be operatively connected to the third pivot so as to position the third pivot in a first position or a second position;positioning a forward end of the truck beam in a raised position relative to an aft end of the truck beam by causing the truck pitch actuation system to be in a take-off position while the airplane is in air; andpositioning the forward end of the truck beam in a lower position relative to the aft end of the truck beam by causing the truck pitch actuation system to be in a stow position while the airplane is in the air to facilitate retraction of the landing gear. 2. The method of claim 1 wherein the plurality of links comprise a semi-levered landing gear linkage and a first and a second lock link, wherein positioning the forward end of the truck beam in the raised position relative to the aft end of the truck beam comprises positioning the semi-levered landing gear linkage and the first and the second lock link to define an acute angle therebetween that opens toward the truck beam, and wherein positioning the forward end of the truck beam in the lower position relative to the aft end of the truck beam comprises positioning the semi-levered landing gear linkage and the first and the second lock link to define an obtuse angle therebetween that opens toward the truck beam. 3. The method of claim 2 further comprising maintaining the semi-levered landing gear linkage in an extended position as the truck beam is repositioned from a landing position in which the forward end of the truck beam is in the raised position relative to the aft end of the truck beam to the stow position in which the forward end of the truck beam is in the lower position relative to the aft end of the truck beam. 4. The method of claim 2 wherein the first and the second lock link are extended in both a landing position in which the forward end of the truck beam is in the raised position relative to the aft end of the truck beam and the stow position in which the forward end of the truck beam is in the lower position relative to the aft end of the truck beam, and wherein the method further comprises causing the first and the second lock link to fold as the truck beam is repositioned from the landing position to the stow position. 5. The method of claim 1 further comprising permitting the plurality of links to fold so that the forward end of the truck beam is raised relative to the aft end of the truck beam in response to a force on the forward end of the truck beam while the forward end of the truck beam is positioned in the lower position relative to the aft end of the truck beam. 6. The method of claim 1 wherein a weight-carrying capacity of the airplane is increased. 7. The method of claim 1 further comprising maintaining the third pivot in the first position with the third pivot having a fixed first relationship with respect to the outer cylinder so as to allow raising of the forward end of the truck beam, relative to the aft end of the truck beam, during extension of the shock strut. 8. The method of claim 1 further comprising maintaining the third pivot in the second position with the third pivot having a fixed second relationship with respect to the outer cylinder so as to allow positioning of the truck beam in the stow position. 9. The method of 1 wherein the first and the second links have a range of angular rotation with respect to one another that is limited to an off-center orientation in which the first and second links are not aligned. 10. The method of claim 9 wherein positioning the forward end of the truck beam in the raised position relative to the aft end of the truck beam comprises limiting a pitch of the truck beam at take-off by the off-center orientation between the first and the second link and extension of the shock strut. 11. The method of claim 1 wherein the first and the second link comprise respective stops for limiting relative movement of the first and the second link. 12. The method of claim 1 wherein providing the semi-levered landing gear mechanism further comprises providing at least one biasing device extending between the first and the second link. 13. The method of claim 1 wherein providing the semi-levered landing gear mechanism further comprises providing at least one biasing device extending between the first link and the truck beam. 14. The method of claim 1 wherein providing the semi-levered landing gear mechanism further comprises providing a first and a second lock link, wherein the first lock link is connected at the third pivot to the third link and at a fifth pivot to the second lock link, and wherein the second lock link is connected at the fifth pivot to the first lock link and at a sixth pivot to the shock strut. 15. The method of claim 14 wherein the truck pitch actuation system is operatively connected to the first lock link intermediate of the third and the fifth pivot. 16. The method of claim 14 wherein the first and the second lock link comprise respective stops for limiting relative movement of the first and the second lock link.
