    • An aircraft comprises a wing (2) defining an aerofoil surface, the wing (2) comprising a drooped leading edge flap (1) being moveable between a stowed position and a deployed position. The wing (2) is so arranged that during flight when the high-lift device is in the deployed position, air may flow through an opening (7) in the wing (2) and over the aerofoil surface. During flight, air preferably flows into the boundary layer (13) on the upper surface of the wing (2). This energises the boundary layer (13), aft of the trailing edge of the drooped leading edge flap increasing its stability allowing the maximum achievable lift coefficient to be increased and hence reducing aircraft take-off and approach speeds.
    • 飞行器包括限定翼面的翼(2),所述翼(2)包括可在收起位置和展开位置之间移动的下垂的前缘翼片(1)。 机翼(2)被布置成使得在高升力装置处于展开位置时的飞行中,空气可以流过机翼(2)中的开口(7)并且在机翼表面上方流动。 在飞行中,空气最好流入机翼(2)上表面上的边界层(13)。 这使能边界层(13),下垂的前缘翼片的后缘的后部增加了其稳定性,从而可以增加最大可实现的升力系数,从而减少飞机起飞和进近速度。
