Abstract: A ducted fan integrated power plant unit having a propeller with a central blade wheel comprises a ducted fan stator, which stator includes an outer ring having the central air intake guide ring, an inner ring; stator guide blades connecting the outer ring and the inner ring and a fixing support, a propeller, which includes main blades, a retaining ring, the later has central conical blades, between which guide openings are formed, and an engine and a fuel tank etc. When they are mounted together, the inner ring opening of the stator can be communicated with the guide openings, thereby the air flow volume is increased and air stream can be also guided to be exhausted towards the rear by these openings, at the same time the crankcase of the engine can be effectively cooled and the power and propulsion of engine can be increased.

Abstract: 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.
