초록

A slat is selectively extended from a main wing body, with a concave rear surface of the slat facing a convex forward nose surface of the wing body, with a slat gap therebetween. At least one row of flexible bristles is movably arranged relative to the lower rear edge of the slat, to flexibly protrude up into the slat air gap. At least one row of flexible bristles is movably arranged along the upper rear edge of the slat to extend rearwardly over the slat air gap and the upper surface of the main wing body. The flexible bristles are flexibly self-positio...

1. In an aircraft including a wing arrangement, wherein said wing arrangement includes a wing body and a slat, said wing body terminates forwardly in a forward nose of said wing body, said slat has a concave rear surface facing toward said forward nose, and said slat is movably connected to said wing body to be movable between a retracted slat position in which said slat is adjacent to said forward nose with said concave rear surface facing and adjacent to said forward nose and an extended slat position in which said slat is spaced away from said forward...
