An incongruous five-propeller helicopter is characterized in that a central propeller is arranged at the center of an equilateral triangle of the projection of the connecting line of the rotating centers of the other three same fixed-pitch propellers on the horizontal plane, the center is on the gravity center of the helicopter body or slightly behind the gravity center, one height of the triangleis overlapped with the longitudinal axis of the helicopter body, a tail fixed-pitch propeller is arranged at the tail of the helicopter body, the rotating surface of the tail fixed-pitch propeller isperpendicular to or approximately perpendicular to the rotating surface of the central propeller and is parallel to the longitudinal axis of the helicopter body, an undercarriage is arranged below the helicopter body and close to the gravity center, three same engines are arranged to drive the fixed-pitch propellers at the vertex angle of the triangle, another engine is arranged to drive the central fixed-pitch propeller, another engine is arranged to drive the tail fixed-pitch propeller, the central fixed-pitch propeller provides most of lift force and forward flying power, the tail fixed-pitch propeller controls the course, and a gasoline-electric hybrid or full-fuel driving method is adopted, so that the helicopter has the advantages of long endurance time and large load capacity, andis applied to transportation, aerial photography, agricultural operation and the like.
一种不全等五螺旋桨直升机,一个中心螺旋桨设置在另外三个相同的定距螺旋桨的旋转中心的连线在水平面的投影是等边三角形的中心上,该中心在机身重心上或略后,该三角形的其中一条高与机身纵轴重叠,机身尾部设置一个尾定距螺旋桨,尾定距螺旋桨的旋转面垂直或近似垂直于中心螺旋桨的旋转面,且与机身纵轴平行,机身下靠近重心附近设置起落架,设置三个相同的发动机驱动,该三角形顶角上的定距螺旋桨,设置另一个发动机驱动中心定距螺旋桨,设置另一个发动机驱动尾定距螺旋桨,中心定距螺旋桨提供大部分的升力和前飞动力,尾定距螺旋桨操纵航向,采用油电混合或全燃油的驱动方法,具有续航时间长,载重量大的优点,应用于运输、航拍、农业作业等。
