A central turbo ducted fan integrated power plant unit comprises a central turbine having turbine blades and retaining ring, fan duct stator, internal combustion engine, fuel tank. There are provided central turbine blades on the retaining ring. The fan duct stator includes an outer ring, an inner ring, stator guide blades, turbine guide blades and the fixing supports on which the internal combustion engine and fuel tank are fixed. The central turbine is mounted on the fan duct stator and the inner hole or guide hole containing the central turbine blades is communicated with the inner hole of the inner ring. On the front end of the fan duct stator is provided a guide ring with diameter or inner diameter being reduced gradually from the front toward the rear, thereby the volume of air flow to be expelled can be increased and the air stream can be guided to be expelled linearly reward and the disordered air flow can be prevented from occurring. At the same time, the jetted air stream can cool the crankcase of the engine, thereby the success start rate and the propulsion force of the engine can be raised. The present utility model further has the advantages of simple and integrated structure, high efficiency and light weight.
