The invention discloses a parallel reverse double-rotor helicopter transmission system. Under the normal working condition, an engine drives rotors to rotate through a speed reducer and drives a powergenerator to work through a differential mechanism; one part of generated electric energy is stored in an energy storage unit, and the other part of the generated electric energy is provided for other accessories; when the engine has a fault, an auxiliary power unit is changed into a power output mode, the energy storage unit provides the stored energy for a helicopter system as kinetic energy through the differential mechanism so as to keep the normality of the system and guarantee the stable flying of a helicopter; and therefore, problems of complicated structure, large mass and low reliability of an existing helicopter transmission system are solved. The parallel reverse double-rotor helicopter transmission system is used for transmission of rotor helicopters. 本发明公开一种并排反向双旋翼直升机传动系统，在正常工况下，发动机通过减速器带动旋翼转动，同时通过差速
