The invention discloses a distributed ducted wing mechanism with variable outlets, which comprises a ducted wing surface, a central propulsion unit, a trailing edge control surface, a flexible sealing material and a torsion motor, the central propulsion unit is fixedly mounted in the ducted wing surface, and a connecting joint is fixedly arranged on the outer surface of a central cone at one end of the central propulsion unit; according to the distributed ducted wing mechanism with the variable outlet, by designing the trailing edge mechanism with the variable geometrical shape, the control surface is shrunk in the axial direction of the duct during vertical take-off and landing, and meanwhile, the tail part is expanded in the radial direction, so that the length-diameter ratio of the duct is reduced, the outlet area is enlarged, airflow is effectively diffused, the sinking airflow speed is reduced, and meanwhile, the thrust is improved. During level flight, the mechanism pushes the control surface to axially extend out along the duct, and meanwhile, the tail part shrinks in the radial direction, so that the outlet size of the duct is reduced, the windward area is reduced, the chord length of the wings is increased, the resistance is reduced, and the lift force is improved.

    本发明公开了一种可变出口的分布式涵道机翼机构,包括涵道翼面、中心推进单元、后缘舵面、柔性密封材料和扭转电机,所述涵道翼面的内部固定安装有中心推进单元,所述中心推进单元一端的中心锥体外表面固定设置有连接接头,该可变出口的分布式涵道机翼机构,通过设计此可变几何形状的后缘机构,在垂直起降时舵面沿涵道轴向收缩,同时尾部沿径向扩张,使涵道长径比减小,出口面积变大,气流得到有效扩散,降低下沉气流速度,同时提高推力。平飞时此机构推动舵面沿涵道轴向伸出,同时尾部沿径向收缩,减小了涵道出口尺寸,减少了迎风面积,同时增加了机翼的弦长,降低了阻力,提高了升力。
