An aircraft wing (102, Fig. 2) is provided that includes a leading edge slat (110 ') and a fixed airfoil portion (104). The leading edge slat (110 ') is movable between a stowed position and a deployed position. In the deployed position, the trailing edge of the leading edge slat includes a sealing portion (112) and a non-sealing portion (114). The sealing portion (112) forms a seal with the fixed airfoil portion and the non-sealing portion provides an airflow gap between the leading edge flap and the fixed airfoil portion. The present invention provides substantially the same benefits as a sealed leading edge slat while improving stall control characteristics in local areas around the non-sealed portion.
本发明提供了一种飞行器机翼(102,图2),该飞行器机翼包括前缘缝翼(110’)和固定翼型件部分(104)。前缘缝翼(110’)能够在收起位置与展开位置之间移动。在展开位置,前缘缝翼的后缘包括密封部分(112)和非密封部分(114)。密封部分(112)与固定翼型件部分形成密封,并且非密封部分在前缘襟翼与固定翼型件部分之间提供气流间隙。本发明提供了与密封的前缘缝翼基本相同的益处,同时改进了非密封部分周围的局部区域中的失速控制特性。
