The invention relates to the field of unmanned aerial vehicle helicopters, in particular to a tandem dual-rotor unmanned helicopter which comprises an unmanned aerial vehicle body and a damping device installed on the lower surface of the unmanned aerial vehicle body. The damping device comprises a fixing plate fixedly connected to the lower surface of the unmanned aerial vehicle body, a damping plate arranged below the fixing plate and a plurality of supporting rods symmetrically installed at the two ends of the damping plate, the length direction of the fixing plate and the length direction of the damping plate are the same as the length direction of the unmanned aerial vehicle body, and one end of each supporting rod is connected with the damping plate. A first damping assembly is arranged between the fixing plate and the damping plate and comprises a plurality of first damping springs installed between the fixing plate and the damping plate, one end of each first damping spring is connected with the fixing plate, and the other end of each first damping spring is connected with the damping plate. The multiple first damping springs are evenly distributed in the circumferential direction of the edges of the fixing plate and the damping plate. The effect of improving the damping performance of the unmanned aerial vehicle is achieved.
