A slat high lift system comprises a slat, at least one driving mechanism, at least one involved guide mechanism, a first wing rib and a second wing rib, the driving mechanism is provided with a parallelogram mechanism, and the peak of the parallelogram mechanism, namely a slat driving point, moves along a first guide sliding rail arranged on the first wing rib. The slat is driven to perform the same circular motion as the sliding rail type slat, the traction guide mechanism forms a three-connecting-rod mechanism, one end of the traction guide mechanism forms a traction point connected with the slat, the other end of the traction guide mechanism forms a traction mechanism fixed point fixed to the second wing rib, and a sliding guide point of the three-connecting-rod mechanism moves along a second guide sliding rail arranged on the second wing rib. The curve of the first guide sliding rail is formed by fitting according to the same circular motion as the sliding rail type slat, and the curve of the second guide sliding rail is set to enable a connection point to be always located on the same circumference as a slat driving point. A front beam of a wing does not need to be penetrated, and the same lowering angle as a traditional sliding rail type slat can be guaranteed.
一种缝翼高升力系统,包括缝翼、至少一个驱动机构、至少一个牵连导向机构、第一翼肋和第二翼肋,驱动机构具有平行四边形机构,通过使平行四边形机构的顶点即缝翼驱动点沿设置于第一翼肋的第一导向滑轨移动,驱动缝翼进行与滑轨式缝翼相同的圆周运动,牵连导向机构构成为三连杆机构,一端构成为与缝翼连接的牵连点,另一端构成为固定于第二翼肋的牵连机构定点,三连杆机构的滑动引导点沿设置于第二翼肋的第二导向滑轨移动,第一导向滑轨的曲线根据与滑轨式缝翼相同的圆周运动进行拟合而成,第二导向滑轨的曲线设置成使牵连点始终位于与缝翼驱动点相同的圆周上。无需穿透机翼的前梁,并且可以保证与传统滑轨式缝翼相同的下放角度。
