The invention discloses a lift-augmentation slotted simple flap structure which comprises a control surface part connected to a wing rear beam of a wing, the lift-augmentation slotted simple flap structure further comprises a trailing edge flow channel, and the trailing edge flow channel is located at the segmentation position of the wing and the control surface part and used for enabling high-pressure airflow of a lower wing surface to flow into an upper wing surface. According to the high-lift slotted simple flap structure, high-pressure airflow of the lower airfoil flows to the upper airfoil through the rear edge flow channel, energy is provided for the upper airfoil, airflow separation of the upper airfoil is slowed down, and therefore the take-off lift force and the cruise lift-drag ratio are effectively improved.

    本申请公开了一种增升开缝简单襟翼结构,包括连接于机翼的机翼后梁的舵面部件,所述增升开缝简单襟翼结构还包括后缘流道,所述后缘流道位于机翼与所述舵面部件的分段处,所述后缘流道用于使下翼面的高压气流流入上翼面。上述增升开缝简单襟翼结构,通过后缘流道使下翼面的高压气流流到上翼面,为上翼面提供能量,减缓上翼面气流分离,从而有效提升起飞升力和提高巡航升阻比。
