The invention discloses an aviation parallel hybrid power system which is composed of a heavy oil rotor engine, a permanent magnet motor/generator, a rectifier/controller, a battery pack and a planetary gear coupler. The engine, the electric motor/generator and the planetary gear coupler are designed in an integrated structure, share a cooling system and a lubricating system and are connected through a shaft in a penetrating mode, so that the system is small in overall size and compact in structure. A bearing is arranged at the tail end of the motor/generator to support the integrated shaft, the rigidity of the shaft is enhanced, and the whole structure is more stable. The engine and the motor/generator are subjected to torque coupling through the planetary gear coupler, an outer gear ring of the planetary gear is connected with the engine, the sun gear is connected with the motor/generator, the outer gear ring and the sun gear are in meshing transmission through the planetary gear, and power is output to the propeller through the planetary carrier. The aviation parallel type hybrid power system has the advantages of being high in power-to-weight ratio, high in energy utilization rate, highly compact in structure and the like.
