The invention belongs to the field of helicopters, and discloses a coaxial double-rotor tailed propeller transmission system and a helicopter, and the transmission system comprises a first bevel gear,a first reversing bevel gear, a second bevel gear, a second reversing bevel gear, a third reversing bevel gear, a first planetary gear train, a second planetary gear train, a third bevel gear and a tailed propeller output shaft. The first reversing bevel gear is meshed with the first bevel gear; the second bevel gear is in transmission connection with the first reversing bevel gear, and the second bevel gear is meshed with the second reversing bevel gear and the third reversing bevel gear; the first planetary gear train is in transmission connection with the second reversing bevel gear, and the second planetary gear train is in transmission connection with the third reversing bevel gear; the third bevel gear is meshed with the second reversing bevel gear and the third reversing bevel gear, and the tail push output shaft is in transmission connection with the third bevel gear. Tail pushing transmission is set to be two-stage transmission output, coaxial double rotors are set to be three-stage transmission output, and the transmission requirements of tail pushing and the coaxial double rotors can be met at the same time.
