Abstract

A flap system driving a leading-edge flap between retracted and extended positions comprises a leading-edge flap, an actuator, first, second and third fixed links, first and second connecting links, and an auxiliary link. The first, second and third fixed links are rotatably supported on respective first, second and third structurally fixed points by respective first, second and third support joints. The first fixed link couples with an end of the first connecting link, which is coupled with a first flap joint at another end. The second fixed link rotatably couples with a central region of the first connecting link. The third fixed link rotatably couples with an end of the second connecting link, which is coupled with a second flap joint at another end. The second connecting link couples with the first fixed link through the auxiliary link, each at positions inside of the respective ends.
