The invention provides a double-engine tandem type unmanned helicopter which comprises a helicopter body. A front rotor wing assembly and a rear rotor wing assembly are arranged on the front portion and the rear portion of the top of the helicopter body respectively. The driving system comprises a driving part, a front transmission part and a rear transmission part, the driving part is composed of two aviation turboshaft engines and a parallel operation reduction gearbox, the two aviation turboshaft engines are both connected to the parallel operation reduction gearbox, and the two ends of an output shaft of the parallel operation reduction gearbox are connected with the front transmission part and the rear transmission part respectively; the front transmission part and the rear transmission part are respectively connected with the front rotor wing assembly and the rear rotor wing assembly; and the lubricating mechanism is mounted at the position of a box body of the parallel operation reduction gearbox so as to carry out self-lubrication on internal elements of the parallel operation reduction gearbox. The two aviation turboshaft engines and the parallel operation reduction gearbox are adopted as power sources, so that the whole tandem type unmanned helicopter meets the requirements of heavy transportation and plateau flight environments.
