An integrated propeller helicopter is disclosed. A plurality of propellers are integrated into an integrated propeller driven by a common driving shaft in a manner that each two adjacent propellers synchronously rotate in reversed directions, the horizontal projections of the rotating surfaces of each two adjacent propellers are partially overlapped, each two adjacent diagonal propellers have thesame rotating speed and the same rotating direction, and the horizontal projections of the rotating surfaces of each two adjacent diagonal propellers are not overlapped. The maximum area polygon of the connecting line of the lift centers of the propellers in the integrated propeller is rectangular, trapezoidal or triangular. An integrated propeller helicopter is composed of two same integrated propellers. Fishbone-shaped cross arms are arranged on the left and right sides of a fuselage to correspondingly support the left and right integrated propellers; an engine is arranged to drive the leftand right integrated propellers at the same time, a horizontal tail wing is arranged at the tail of a helicopter body, the integrated helicopter with the tension (or thrust) propellers increased can take off in a sliding mode like a fixed-wing aircraft and can take off vertically or take off in a sliding mode, and wheel type undercarriages are arranged below the helicopter body. The integrated propeller helicopter is applied to the fields of rescue, transportation, aerial photography and the like.

    一种集成螺旋桨直升机,将多个螺旋桨以相邻两个螺旋桨同步反转,相邻两个螺旋桨的旋转面在水平的投影部分重叠,相邻对角两个螺旋桨转速相同转向相同,相邻对角两个螺旋桨的旋转面在水平的投影不重叠的方法集成为由一个公共驱动轴驱动的集成螺旋桨,集成螺旋桨里的螺旋桨的升力中心的连线的最大面积多边形是矩形或是梯形或是三角形,由两个相同的集成螺旋桨构成集成螺旋桨直升机,机身左右设置鱼骨形横臂对应支承左右集成螺旋桨,设置一个发动机同时驱动左右集成螺旋桨,机身尾部设置水平尾翼,增加拉力(或推力)螺旋桨的集成直升机能够象固定翼飞机一样滑跑起飞,可垂直起降也可滑跑起降,机身下设置轮式起落架,应用于救援,运输,航拍等领域。
