A planetary propeller helicopter is composed of four identical propellers. Connecting lines of projections of rotating centers of the three propellers on a horizontal plane form an equilateral triangle; the three propellers are arranged on a left side, a right side and a rear side of a fuselage; the projection of the rotating center of a remaining rotor wing on the horizontal plane is on the center of the equilateral triangle; or, the connecting lines of the projections of the rotating centers of the three propellers on the horizontal plane form the equilateral triangle; the three propellers are arranged on the left side, the right side and the front side of the fuselage; the projection of the rotating center of the remaining rotor wing on the horizontal plane is on the center of the equilateral triangle; the projection of a gravity center of the planetary propeller helicopter on the horizontal plane is on the center of the equilateral triangle; and an undercarriage is arranged below the fuselage and close to the gravity center, a center propeller and a tail propeller or a front propeller are the same in rotating direction and opposite to the left propeller and the right propellerin rotating direction, and the helicopter is compact in structure, low in weight and suitable for flying in a narrow space.

    一种行星螺旋桨直升机,由四个完全相同的螺旋桨构成,其中三个螺旋桨的旋转中心在水平面的投影的连线是等边三角形,这三个螺旋桨分别设置在机身的左边、右边和后边,剩下一个旋翼的旋转中心在水平面的投影在该等边三角形的中心上,或者,其中三个螺旋桨的旋转中心在水平面的投影的连线是等边三角形,这三个螺旋桨分别设置在机身的左边、右边和前边,剩下一个旋翼的旋转中心在水平面的投影在该等边三角形的中心上,行星螺旋桨直升机的重心在水平面的投影在该等边三角形的中心上,机身下靠近重心附近设置起落架,中心螺旋桨与尾部螺旋桨或前部螺旋桨的转向相同,与左边螺旋桨和右边螺旋桨的转向相反,结构紧凑,重量较轻,适合在狭窄的空间飞行。
