The invention discloses a parallel helicopter which is characterized in that a first single-rotor helicopter is connected with a second single-rotor helicopter through a connecting cross beam on the basis of the first single-rotor helicopter, and the longitudinal axis of the connecting cross beam is overlapped with or parallel to the projection of a connecting line of rotating centers of rotors of the first single-rotor helicopter and the second single-rotor helicopter on a horizontal plane; a warehouse fuselage is arranged near the midpoint of the connecting cross beam, the rotating directions of rotors of the first single-rotor helicopter and rotors of the second single-rotor helicopter are the same, in order to further increase lift force, a propeller is arranged at the top of the warehouse fuselage, and the rotating direction of the propeller is opposite to the rotating directions of the two rotors of the parallel helicopters; the control load of a tail propeller is reduced, more propellers are additionally arranged on the two sides of the warehouse fuselage to achieve re-increase of lift force, the engine driving rotors, the warehouse fuselage top propeller, the warehouse fuselage two-side propellers and the tail propeller are driven by the engine driving the rotors through transmission shafts, and the transverse arrangement is suitable for wide agricultural operation occasions.

    一种并列式直升机,在第一单旋翼直升机的基础上,通过连接横梁联接第二单旋翼直升机,连接横梁的纵轴与第一单旋翼直升机的旋翼和第二单旋翼直升机的旋翼的旋转中心的连线在水平面的投影重叠或平行,在连接横梁的中点附近设置货仓机身,第一单旋翼直升机的旋翼和第二单旋翼直升机的旋翼的旋转方向相同,为了进一步增加升力,在货仓机身顶部设置一个螺旋桨,螺旋桨的旋转方向与并列式直升机的两个旋翼的旋转方向相反,减轻了尾螺旋桨的操纵负荷,增设更多的螺旋桨在货仓机身两边实现升力再增加,分别设置发动机驱动旋翼、货仓机身顶部螺旋桨、货仓机身两边螺旋桨,尾螺旋桨由驱动旋翼的发动机通过传动轴驱动,横列式布局适合宽幅、农业作业的场合。
