The invention discloses a distributed electric ducted fan power system for short-distance/vertical take-off and landing, and belongs to the field of aviation aircrafts. The system comprises a duct power unit, an upper high-lift airfoil and a lower high-lift airfoil, the duct power set comprises a plurality of duct power units which are arranged in parallel; the end faces of the two sides of the upper high-lift airfoil and the two sides of the lower high-lift airfoil are connected with steering engines installed on the fuselage through connecting rods and located above and below the outer side of an outlet of the duct power set correspondingly, and the rotating angles of the upper high-lift airfoil and the lower high-lift airfoil are controlled through the steering engines. The upper high-lift airfoil comprises an upper high-lift airfoil main wing and an upper high-lift airfoil flap, and the lower high-lift airfoil comprises a lower high-lift airfoil main wing and a lower high-lift airfoil flap. By changing the deflection angle and form of the upper high-lift airfoil and the lower high-lift airfoil, the limitation of a power system on aerodynamic layout is reduced, and distribution and utilization of power in different stages such as take-off and landing and cruising are facilitated.

本发明一种用于短距/垂直起降的分布式电涵道风扇动力系统，属于航空飞行器领域；包括涵道动力组、上增升翼面和下增升翼面；所述涵道动力组包含多个并列设置的涵道动力单元；所述上增升翼面和下增升翼面的两侧端面均通过连杆与安装于机身上的舵机连接，分别位于涵道动力组出口外侧的上方和下方，通过舵机控制上、下增升翼面的旋转角度；所述上增升翼面包括上增升翼面主翼和上增升翼面襟翼，下增升翼面包括下增升翼面主翼和下增升翼面襟翼；通过改变上增升翼面和下增升翼面的偏转角度和形态，实现降低动力系统对气动布局的限制，有利于起降与巡航等不同阶段动力的分配利用。
