Embodiment 1

[0030] The turbofan blades in the duct are divided into two groups, front and rear. The two power groups are side by side and coaxially linked. The power wheel of the power group is similar to the supercharged turbine of a car, and the power shell of the turbo power group is similar to the turbocharged shell of a car. The shaft elevation of the power shell has a 170-degree opening. The combustion gas in the combustion chamber pushes the power wheel to eject from the opening. The exposed power wheel teeth are connected to the normal temperature air to reduce the temperature of the power wheel. The first power shaft It is linked with the second power shaft gear, so that the power group can drive the turbofan blades to rotate. The power wheel 10 and the turbofan blades 7 are both straight blades. The combustion mixture ejected by the two power groups is inside the turbofan duct, and the combustion mixture is mixed with the combustion gas of the acceleration nozzle and the airflow ...

Embodiment 2

[0032] The turbofan blades in the duct are divided into two groups, front and rear. The two power groups are side by side and coaxially linked. The power wheel of the power group is similar to the supercharged turbine of a car, and the power shell of the turbo power group is similar to the turbocharged shell of a car. The shaft elevation of the power shell has a 170-degree opening. The combustion gas in the combustion chamber pushes the power wheel to eject from the opening. The exposed power wheel teeth are connected to the normal temperature air to reduce the temperature of the power wheel. The first power shaft It is linked with the second power shaft gear, so that the power group can drive the turbofan blades to rotate. The power wheel 10 is provided with a tile-shaped blade, and the turbofan blade 7 is formed by splicing two arc-shaped blades. The combustion mixture ejected by the two power groups is inside the turbofan duct, and the combustion mixture and the acceleration...

Embodiment 3

[0035] The turbofan blades in the duct are divided into two groups, front and rear. The two power groups are side by side and coaxially linked. The power wheel of the power group is similar to the supercharged turbine of a car, and the power shell of the turbo power group is similar to the turbocharged shell of a car. The shaft elevation of the power casing has a 170-degree opening, and two-fifths of the teeth of the power wheel are exposed. The combustion gas in the combustion chamber pushes the power wheel to eject from the opening, and the exposed teeth of the power wheel meet the normal temperature air. , in order to reduce the temperature of the power wheel, the first power shaft and the second power shaft gear are linked together, so that the power group can drive the turbofan blades to rotate. The power wheel 10 is provided with a tile-shaped blade, and the turbofan blade 7 is formed by splicing two arc-shaped blades. The combustion mixture ejected by the two power group...

Description

technical field [0001] The invention relates to the technical field of engine equipment, in particular to an aero-engine. Background technique [0002] The full name of the turbofan engine is a turbofan engine, which is a type of aircraft engine developed from a turbojet engine. Compared with the turbojet, the main feature is that the area of ​​the first stage compressor is much larger, and it is also used as an air screw fan, which pushes part of the intake air backward through the periphery of the jet engine. The part where the air in the core part of the engine passes is called the inner duct, and the outer part of the core engine that only the fan air passes through is called the outer duct. Turbofan engines are most suitable for use when flying at a speed of 400 to 1,000 kilometers, so most aircraft engines now use turbofans as a power source. [0003] The existing turbofan has the disadvantages that the engine starts slowly, and the high-speed turbofan is damaged due...
