The invention provides a vector thrust ducted propeller with inlet and outlet adjustable grids. The vector thrust ducted propeller comprises a ducted shell (1), an inlet grid (2), an outlet grid (3),an inlet grid frame ring (4) and an outlet grid frame ring (5). The inlet grid (2) is composed of a plurality of grid blades, each grid blade is of a symmetrical wing-shaped structure, the distance between every two adjacent grid blades is the chord length of the corresponding grid blade, and all the grid blades are installed on the inlet grid frame ring (4) in parallel through rotating shafts; the outlet grid (3) is the same structure as the inlet grid (2) and is arranged on the outlet grid frame ring (5) through a rotating shaft; and the inlet grid frame ring (4) and the outlet grid frame ring (5) are respectively fixed at an inlet and an outlet of the ducted shell (1). A complex periodic variable pitch mechanism on a traditional propeller is omitted, the structure is simple, the weightis light, and the reliability is improved. The angle of the duct inlet adjustable grid, the angle of the duct outlet grid and the total pitch of the propeller can be controlled.
本发明提供一种带进出口可调格栅的矢量推力涵道螺旋桨,包括涵道壳体(1)、进口格栅(2)、出口格栅(3)、进口格栅架环(4)、出口格栅架环(5);进口格栅(2)由多个格栅叶片组成,格栅叶片为对称的翼型结构,相邻格栅叶片的间距为格栅叶片的弦长,所有格栅叶片分别通过转轴平行安装在进口格栅架环(4)上;出口格栅(3)与进口格栅(2)结构相同,通过转轴安装在进口格栅架环(5)上;进口格栅架环(4)、出口格栅架环(5)分别固定在涵道壳体(1)的进口和出口;本发明取消了传统螺旋桨上复杂的周期变距机构,结构简单,重量轻,增加了可靠性。可以控制涵道进口可调格栅角度、涵道出口格栅角度和螺旋桨总距。
