A wing leading edge slat actuation and positioning system, wherein a slat panel is connected to one end of an extensible track member which is supported and guided at its other end, by rollers mounted to fixed structure in the leading edge section of the wing. The actuation and positioning system comprises a unified drive and a programming mechanism which is connected to the slat panel and functions to combine an aerodynamic slot opening or closure operation with a slat extension drive mechanism. The unified drive and programming mechanism comprises a contoured camtrack somewhat in the shape of an S-camtrack and having a roller follower which is connected to a link and drive arm; and this combination allows synchronization of slat actuation with programming control of slat angle-of-deflection and aerodynamic slot opening or closure.

A mechanism for extending and positioning a high-lift device relative to an airfoil, comprising: a carrier track extending chordwise in said airfoil and being pivotally connected at one end to said high-lift device; means mounted to said airfoil for supportably guiding the other end portion of said carrier track for chordwise extension movement of said high-lift device relative to said airfoil; a camtrack spaced spanwise from said carrier track and fixedly mounted chordwise in said airfoil; a rotary actuator mounted in said airfoil; a linkage mechanism being in a folded arrangement during a fully retracted position of said high-lift device relative to said airfoil and interconnecting said high-lift device with said camtrack and said rotary actuator; said rotary actuator in combination with said linkage mechanism, said camtrack and said carrier track, effecting a simultaneously combined unfolding linkage extension movement of said high-life device on said carrier track from said airfoil, and a camtrack guided angle-of-incidence programming of said high-lift device relative to said airfoil; and said camtrack producing a guided force vector component to said linkage mechanism during unfolding linkage extension movement of said high-lift device, for enabling said linkage mechanism to freely operate a complete extension cycle of said high-lift device without locking up.
