The invention relates to a double-duct unmanned aerial vehicle, wherein a first propeller is coaxially arranged in a first duct shell, and a second propeller is coaxially arranged in a second duct shell; a first control surface group and a third control surface group are respectively positioned below the first propeller, and a second control surface group and a fourth control surface group are respectively positioned below the second propeller; the first control surface group and the second control surface group are respectively perpendicular to a connecting straight line where the axis of the first duct shell and the axis of the second duct shell are located; and the third control surface group and the fourth control surface group are respectively parallel to a connecting straight line where the axis of the first duct shell and the axis of the second duct shell are located, and are respectively symmetrical about the connecting straight line where the axis of the first duct shell and the axis of the second duct shell are located. By means of the four control surface groups, change of the engine rotating speed and the duct lifting force surface direction is not required. The aircraft can be controlled by controlling the deflection angle of the control surface, the attitude of the aircraft can be quickly adjusted, the response speed is high, and the aircraft flies stably.
本发明涉及一种双涵道无人飞行器,其中第一螺旋桨同轴设置于第一涵道壳体内部,第二螺旋桨同轴设置于第二涵道壳体内部;第一舵面组和第三舵面组分别位于第一螺旋桨的下方,第二舵面组和第四舵面组分别位于第二螺旋桨下方;第一舵面组以及第二舵面组分别垂直于第一涵道壳体轴心和第二涵道壳体轴心所在连接直线;第三舵面组及第四舵面组分别平行于第一涵道壳体轴心和第二涵道壳体轴心所在连接直线,且分别关于第一涵道壳体轴心和第二涵道壳体轴心所在连接直线对称,利用四个舵面组无需改变发动机的转速以及涵道升力面方向,通过控制舵面的偏转角度即可控制飞行器,可快速调整飞行器姿态,响应速度快,且飞行器飞行过程平稳。
