    • A retractable airfoil assembly (20) augments the wing surface area (28) of an aircraft (22) enabling it to fly without stalling at reduced speeds during takeoff and landing. The airfoil assembly includes flexible sails (42, 44) and a furling mast (24) for extending and retracting the sails. The furling mast includes a furling drum mounted for clockwise and counterclockwise rotation on a static tube (50). The flexible sail assembly also includes guide tracks (80) located along a leading edge (101) or tailing edge (40) of the wings. The tracks guide the flexible sails during extension and retraction. A drive cable (26) extends and retracts the sails (42, 44) along the guide tracks and maintains tension in the sails while they are extended.
    • 可缩回的翼型组件(20)增大了飞机(22)的机翼表面区域(28),使其能够在起飞和着陆期间以降低的速度飞行而不会失速。 翼型组件包括用于延伸和收回帆的柔性帆(42,44)和收拢桅杆(24)。 收拢的桅杆包括一个安装在静态管(50)上顺时针和逆时针旋转的收卷鼓。 柔性帆组件还包括沿着机翼的前缘(101)或后缘(40)定位的导轨(80)。 轨道在延伸和收回期间引导柔性帆。 驱动缆索(26)沿着导轨延伸和缩回帆(42,44),并在帆延伸时保持帆中的张力。
