The invention discloses a tandem dual-rotor unmanned helicopter, and aims to provide the tandem dual-rotor unmanned helicopter which adopts synchronous belt transmission to realize synchronous reverse rotation of a front rotor and a rear rotor, so that the condition that a rigid structure is easy to damage due to synchronous rotation can be avoided; and the layout of rotor systems on the two sides of the unmanned helicopter cannot be restrained. The unmanned aerial vehicle comprises a vehicle body, a first synchronous assembly, a second synchronous assembly and a synchronous belt are arranged on the vehicle body, the first end of the synchronous belt is in transmission with the first synchronous assembly, the second end of the synchronous belt is twisted relative to the first end and is in transmission with the second synchronous assembly, and the first synchronous assembly is in transmission with a front rotor. And the second synchronous assembly is in transmission with the rear rotor wing, and the front rotor wing and the rear rotor wing synchronously and reversely rotate during transmission of the synchronous belt. The invention is applied to the technical field of unmanned helicopters.
