Description
Technical field:
The invention belongs to aero-engine fields, specifically, being a kind of vertical take off and landing fighter power device.
Background technique:
Vertical take off and landing fighter is used to improve air operation efficiency, and vertical take off and landing fighter is few in number in the world at present,
Major defect has: engine research, development is at high cost, and thrust is insufficient, and reliability is low, is unable to supersonic cruise, and air-flow temperature is discharged in nozzle
Du Taigao has an impact to type aircraft carrier deck.
Summary of the invention:
For overcome the deficiencies in the prior art, the present invention provides a kind of vertical take off and landing fighter power devices, and having can
By property height, the advantages of improving maximum take-off weight, be conducive to high-speed flight.
The present invention is achieved through the following technical solutions:
A kind of vertical take off and landing fighter power device includes lift fan and inlet flow deceleration fan and big duct
Compare turbofan, further includes:
There are flow distribution plate at least one split channel, the split channel front end, and there is vector spout in the split channel end,
The flow distribution plate is used to control the air inflow of each split channel,
Further, there is after-burner between the flow distribution plate and the vector spout, the after-burner is located at
In the split channel.
The lift fan and big bypass ratio turbofan transmission axis connection, the transmission shaft are also set up
There is clutch.For fighter plane when taking off vertically or vertical landing, the clutch connection, the transmission shaft drives the lift wind
Fan generates lift；In mission phase, the clutch disconnects fighter plane.
The flow slowing down fan is located in air intake duct, has rolling between the transmission shaft and the flow slowing down fan
Body, the two rotation are not interfere with each other, and the rolling element is additionally provided with lubricating system,
Further, the flow slowing down fan is also connected with gear, is used for transmission power, and power is transferred to output shaft,
One end of the output shaft is provided with gear, and often engages with the flow slowing down fan gear, the other end of the output shaft
It is additionally provided with arrangement of clutch.
For fighter plane when taking off vertically or the vertical landing stage, power is not transmitted in the idle running of flow slowing down fan；Fighter plane exists
When high-speed flight, high-speed flow impacts deceleration fan in air intake duct, and high-speed flow speed after deceleration fan reduces, low speed gas
Stream is more advantageous to big bypass ratio turbofan work, while the fan that slows down obtains additional power, which can transmit
To the other components of fighter plane,
The beneficial effect of vertical take off and landing fighter power device provided by the invention is: the dynamical system uses big bypass ratio
Turbofan possesses bigger thrust and lower oil consumption, while also can adapt to higher flying speed, and theory is suitable
Answer maximum speed up to 3 Mach or more.Not only noise is also low for the lower exhaust of temperature, moreover it is possible to exhaust damage type aircraft carrier deck is avoided,
The power device combines lift fan and shunts spout, and light realization is taken off vertically or the balance of vertical landing, has very high
Practical value.
