Description
Technical field
The application relates to aircraft floor equipment, or cooling technology field, the cooling means of a kind of airplane wheel
And air cooling equipment.
Background technology
Aircraft, when production is taken a flight test, needs to verify the working condition of the system such as Nose Wheel Steering, wheel braking, passes through
The aircraft effectiveness sliding, sliding race check brakes system work under middling speed, high speed.After having slided, aircraft must pass through
Wheel braking slows down.Generally airplane wheel is provided with Hot melt plug, and brake temperature accumulation is easily caused Hot melt plug fusing, rubber
Glue part is aging, the bad phenomenon such as the decline of wheel hub, brake shell equivalent-load ability, brake disc high temperature deformation, is just affecting brake machine wheel
Often use, even affect flight safety.Therefore, after the middle and high ski-running of aircraft is run, excessively braking, the wheel caused is overheated extremely endangers
Danger, it is necessary to take reasonable effective measures to carry out cooling process.
Realize the quick cooling to airplane wheel, nothing more than water-cooled, air-cooled two ways.
Carbon brake disc is applied very universal on airplane wheel, and it is lightweight, wear-resistant, high temperature resistant, corrosion-resistant, friction system
The advantages such as number is stable, stopping power is strong, become the first-selection of current aircraft finance lease.But carbon/carbon material is a kind of porous fragility
Material, has hygroscopicity.If watered to brake disc, brake disc surface and material internal hole are covered by wet gas and water and fill, and stop
During car, steam plays the effect of one layer of lubricant, causes brake torque to be decayed, and moment values reduces and unstable.Test shows,
If carbon brake disc is wet by water, brake torque sharp-decay about 2/3, it may be difficult to ensure Flight Safety.
Brake disc is watered in the condition of high temperature, and water also can react with carbon/carbon compound material, generates CO and H2, makes carbon dish oxygen
Changing serious, structure and intensity are impaired.Forbid watering water cooling when therefore lowering the temperature to wheel, cooling should be forced by air-cooled carrying out.
Prior art has two ways to the air-cooled of airplane wheel.One is facing to wheel by the most hand steered for the ventilation duct of source of the gas
Blowing, when airplane wheel quantity is more, it is necessary to wheel cools down in turn, cooling work becomes troublesome.Two is to use frame
Having the utility cart of electric fan, wheel blows after switching on power cooling, this method is restricted by power supply, the most mostly
Number wind all blows at hub surface, few with the moving air of wheel heat exchange, poor to the cooling effect of airplane wheel brake disk.
Summary of the invention
The present invention is according to the demand at aircraft flight scene, it is provided that the method for rapid cooling of a kind of airplane wheel and air-cooled dress
Put.
The cooling means of a kind of airplane wheel, it is characterised in that 1) there is an air cooling equipment, this air cooling equipment contains cooling
Dish and air intake joint, connected by flexible ventilation duct between cooler pan and air intake joint, cooler pan have and airplane wheel
The air outlet joined；2) cooler pan is fixed on the side of airplane wheel, the air vent of the air outlet correspondence airplane wheel of cooler pan；
3) being connected with cold wind source by air intake joint, cold wind enters cooler pan by air intake joint and ventilation duct, then is blowed to by air outlet
Cooling effect implemented by airplane wheel.
The beneficial effects of the present invention is, 1) by air cooling equipment, the air inlet of source of the gas is fed directly to airplane wheel two
In the air vent of side, it is achieved quickly cooling effect；2) air cooling equipment, can connect multiple cooler pan, simultaneously many to aircraft
Individual wheel implements cooling, practical；3) two cooler pans are by fixing point and fastening rope, can be fixed on airplane wheel easily
Both sides, the air outlet making cooler pan is corresponding with the air vent of airplane wheel, it is achieved the cooling of fast accurate blowing, cooling effectiveness
High；4) air cooling equipment of the application, simple and reasonable, and operational approach is convenient and easy, and autgmentability is strong, can be used for solving various flying
A wheel cooling difficult problem for machine, is quickly reduced to tolerance value by wheel temperature, it is ensured that product quality, improves flight preparation efficiency, have
Actual application value greatly.
