The invention discloses an equilateral triangle helicopter, which adopts four propellers, wherein the connecting lines of the projections of the rotating centers of the right propeller, the left propeller and the tail propeller on the horizontal plane form an equilateral triangle; the height line of the vertex angle of the triangle of the projection of the rotation center of the tail propeller onthe horizontal plane is parallel to the longitudinal line of the equilateral triangle helicopter; the projection of the rotating center of the central propeller on the horizontal plane is in the center of the equilateral triangle; the projection of the rotating center of the central propeller on the horizontal plane, the center of the equilateral triangle formed by the connecting lines of the projections of the rotating centers of the left propeller, the right propeller and the tail propeller on the horizontal plane, and the gravity center of the equilateral triangle helicopter are overlapped;the left propeller, the right propeller and the tail propeller are identical propellers, the left propeller, the right propeller and the tail propeller are same in rotating direction, the rotating direction of the central propeller is opposite to that of the left propeller, and an undercarriage is arranged under the fuselage near the gravity center, so that the helicopter is small in occupied space and can fly in a narrow space.

    一种等边三角形直升机,采用四个螺旋桨,右边螺旋桨、左边螺旋桨和尾螺旋桨的旋转中心在水平面的投影的连线是等边三角形,尾螺旋桨的旋转中心在水平面的投影的三角形的顶角的高线与等边三角形直升机的纵向线平行,中心螺旋桨的旋转中心在水平面的投影在该等边三角形的中心上,中心螺旋桨的旋转中心在水平面的投影、左边螺旋桨、右边螺旋桨和尾螺旋桨的旋转中心在水平面的投影的连线构成的等边三角形的中心和等边三角形直升机的重心重叠,左边螺旋桨、右边螺旋桨和尾螺旋桨是完全相同的螺旋桨,左边螺旋桨、右边螺旋桨和尾螺旋桨的转向相同,中心螺旋桨的转向与左边螺旋桨的转向相反,机身下重心附近设置起落架,占用的空间小,能在狭窄空间飞行。
