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 high lift system for an aircraft, comprising: at least one drive unit,a high lift surface,a plurality of primary drive stations, each primary drive station having a shaft connection couplable with the at least one drive unit and a primary lever couplable with the high lift surface,at least one secondary unit, each secondary unit having a secondary lever couplable with the high lift surface,wherein each one of the plurality of primary drive stations is adapted for moving the respective primary lever on driving the shaft connection,wherein each one of the at least one secondary unit comprises a selectively activatable brake, such that the secondary lever follows the motion of the high lift surface when the brake is deactivated and such that the secondary lever arrests the motion of the high lift surface when the brake is activated; andwherein the high lift surface is coupled with two individual primary drive stations of the plurality of primary drive stations, and is also coupled with one or more of the at least one secondary unit. 2. The high lift system of claim 1, wherein the at least one drive unit is coupled with the plurality of primary drive stations by means of a transmission shaft, andwherein the transmission shaft is coupled with a brake for arresting the rotation of the transmission shaft. 3. The high lift system of claim 1, wherein the high lift surface is coupled with two primary drive stations of the plurality of primary drive stations and two secondary units of the at least one secondary unit. 4. The high lift system of claim 1, wherein a secondary lever is positioned directly adjacent to a primary lever. 5. The high lift system of claim 1, wherein a group of primary drive stations, the group comprising at least two primary drive stations of the plurality of primary drive stations, comprises an individual drive unit. 6. The high lift system of claim 1, further comprising a controller, which is coupled with sensors for detecting at least one operation parameter of the plurality of primary drive stations or in the at least one secondary unit,wherein the controller is adapted for arresting a brake in at least one of the at least one secondary unit, in case the controller determines a mechanical failure based on a comparison of at least one desired operation parameter with the measured at least one operation parameter. 7. The high lift system of claim 1, wherein at least one of the plurality of primary drive stations is coupled with the drive unit by means of a transmission shaft, andwherein at least one of the at least one secondary unit comprises a through-hole, through which the transmission shaft extends. 8. An aircraft comprising: a wing;at least one high lift system, comprising: at least one drive unit,a high lift surface,a plurality of primary drive stations, each primary drive station having a shaft connection couplable with the at least one drive unit and a primary lever couplable with the high lift surface,at least one secondary unit, each secondary unit having a secondary lever couplable with the high lift surface,wherein each one of the plurality of primary drive stations is adapted for moving the respective primary lever on driving the shaft connection,wherein each one of the at least one secondary unit comprises a selectively activatable brake, such that the secondary lever follows the motion of the high lift surface when the brake is deactivated and such that the secondary lever arrests the motion of the high lift surface when the brake is activated; andwherein the high lift surface is coupled with two individual primary drive stations of the plurality of primary drive stations, and is also coupled with one or more of the at least one secondary unit; anda central drive unit located in a wing root region and a transmission shaft extending into the wing and reaching through all primary drive stations of the high lift system. 9. A method for moving a high lift surface relative to a wing of an aircraft, the method comprising the steps of: operating a high lift system of the aircraft, the high lift system comprising: at least one drive unit;the high lift surface;a plurality of primary drive stations, each primary drive station having a shaft connection couplable with the at least one drive unit and a primary lever couplable with the high lift surface; andat least one secondary unit, each secondary unit having a secondary lever couplable with the high lift surface;wherein each one of the plurality of primary drive stations is adapted for moving the respective primary lever on driving the shaft connection;wherein each one of the at least one secondary unit comprises a selectively activatable brake, such that the secondary lever follows the motion of the high lift surface when the brake is deactivated and such that the secondary lever arrests the motion of the high lift surface when the brake is activated; andwherein the high lift surface is coupled with two individual primary drive stations of the plurality of primary drive stations, and is also coupled with one or more of the at least one secondary unit;driving at least one of the plurality of primary drive stations with the primary lever, until a predetermined position is reached, andactivating a brake in a secondary unit of the at least one secondary unit, with the secondary lever of the secondary unit that is activated. 10. The method of claim 9, further comprising: detecting at least one operation parameter of a primary drive station of the plurality of primary drive stations, or a secondary unit of the at least one secondary unit,determining whether at least one intended operation parameter is achieved, andarresting at least one of the at least one secondary unit in case of deviations between the at least one intended operation parameter and the measured at least one operation parameter.
