The invention discloses a fixed-pitch tandem type electric unmanned helicopter. Two rotor wing devices are arranged at the front end and the rear end of a helicopter body respectively, reaction torquecan be counteracted through reverse rotation of the two rotor wing devices, a tail rotor structure does not need to be arranged, the structure of the unmanned helicopter is simple and compact, the tail rotor structure is omitted, vortex influences caused by a tail rotor can be avoided, and the aerodynamic efficiency of the unmanned helicopter is improved. According to a propeller in the unmannedaerial vehicle, fixed pitch is adopted, and electric speed regulation is conducted to realize total pitch control; the front and rear power devices are motors mounted on the helicopter body, the motors adopt electronic speed regulation, and the lifting force is adjusted by adjusting the rotating speed to realize up-and-down movement; through the multi-blade propeller and the swash plate-free modethat the shaft can horizontally rotate, the propeller generates an inclination angle, and front-back movement is achieved; the fixed-pitch tandem type electric unmanned helicopter has the advantages of being simple in structure, reasonable in design, convenient to control, low in failure rate and the like.

    本发明公开了一种定桨距纵列式电动无人直升机,在机身的前后两端各设置一个旋翼装置,通过两个旋翼装置的反向旋转,可抵消反扭矩,无需设置尾桨结构,使得无人直升机的结构简单、紧凑,省去了尾桨结构,可避免由尾桨导致的涡流影响,提高无人直升机的气动效率;该无人机中的螺旋桨,采用定桨距,电动调速实现总距控制;前后动力装置为安装在机身上的电机,电机采用电子调速,通过调整转速来调整升力,实现上下运动;通过多叶螺旋桨以及轴可水平旋转的无斜盘模式,使螺旋桨产生倾角,实现前后运动;该定桨距纵列式电动无人直升机,具有结构简单、设计合理、便于控制以及故障率低等优点。
