The invention discloses a distributed ducted fan power wing electric propulsion system. The distributed ducted fan power wing electric propulsion system comprises wings and tilting mechanisms. Ducted fans are arranged on the upper surfaces of the wings, and the multiple ducted fans are separately arranged in the extension direction of the wings; the tilting mechanism is used for adjusting the tilting angles of the multiple ducted fans, so that the multiple ducted fans at least have the working state of providing vertical lift force and horizontal thrust force; wherein the multiple ducted fans have the same ducted performance, and the distribution parameter XYZ of the ducted fans on the wings, the installation angle a of the ducted wings and other parameters all have specific requirements; after the arrangement mode is adopted, the propelling system can meet different flight working condition requirements of vertical takeoff, tilting transition and cruising flight of the eVTOL aircraft; and through the integrated design of the wings and the ducts, the ducts and the trailing edge flaps form a fused flap duct component, and the propelling performance and aerodynamic efficiency of the novel propelling system are improved through the pneumatic propelling coupling effect and the duct suction effect.

    本发明公开了一种分布式涵道风扇动力翼电推进系统,包括机翼和倾转机构;该机翼上表面设有涵道风扇,多个涵道风扇沿机翼的展长方向分离排列布置;该倾转机构用于调节多个涵道风扇的倾转角度,以使多个涵道风扇至少具备提供竖向升力和水平推力的工作状态;其中,多个涵道风扇具有相同的涵道性能,涵道风扇在机翼上的分布参数XYZ、涵道机翼安装角度a等参数均有特定要求;在采用此设置方式后,将使推进系统满足eVTOL飞行器垂直起飞、倾转过渡和巡航飞行的不同飞行工况需求;并且通过机翼与涵道的一体化设计,使涵道与尾缘襟翼组成融合襟翼涵道组元,通过利用气动推进耦合效应以及涵道抽吸效应,提升新型推进系统的推进性能和气动效率。
