Ice method includes anti-freeze fluid anti-icing system, air bag deicing system etc..Anti-freeze fluid anti-icing system will not generate aerofoil aeroperformance
Energy consumption is few in influence, machine, but simultaneously because anti-freeze fluid useful load is limited, so anti-icing the limited time is (especially in anti-ice formation
Anti-icing limited time when domain is larger), and loading anti-freeze fluid reduces the load of aircraft；Air bag deicing system is simple in structure,
System weight is small, energy consumption is few on machine, but deicing rear aerofoil easily generates residual ice, influences aerofoil aeroperformance.Due to anti-
The difference of the completely different and anti-deicing control sequential of both ice liquid anti-icing system and air bag deicing system structure, causes compound
The anti-deicing system development difficulty of formula anti-freeze fluid-air bag is big, without application in service aircraft.
The content of the invention
The object of the present invention is to the anti-clearing ice technology based on existing aircraft, by combining the anti-icing technology of anti-freeze fluid and air bag
Clearing ice technology designs a combined type anti-freeze fluid-anti-deicing system of air bag.To improve deicing efficiency, it is abundant to increase flight safety
Degree.
In view of the above problem of the prior art, disclosed one side, the present invention use following technology according to the present invention
Scheme：
A kind of combined type anti-freeze fluid-anti-deicing system of air bag, including controller, anti-icing liquid case, pump machine and air bag deicing
Component.Wherein air bag deicing component includes at least deicing air bag (being mounted on the plane airfoil leading edge rear) gentle flow point and is equipped with
It puts (and bleed orifice of the deicing air bag, to the air-blowing of deicing air bag or pumping).When the system works, controller control
Anti-freeze fluid is sprayed to from anti-icing liquid case near aerofoil costa by pump machine, and air bag deicing component is controlled to carry out aerofoil leading edge
Deicing.On the one hand, the system near aerofoil costa by spraying anti-freeze fluid, under airflow function, before anti-freeze fluid airfoil
The rear flowing on the upper and lower surface of edge, forms the liquid film of one layer of reduction freezing point of liquid, drops the super-cooling waterdrop freezing point of aerofoil leading edge
Low, icing difficulty increases；On the other hand, when accumulated ice is after aerofoil leading edge is formed, the anti-freeze fluid of sprinkling will infiltrate into ice sheet rapidly
Bottom makes the reduction of the bond strength of ice sheet and aircraft surfaces.It works with reference to " expansion-contraction " of air bag, aerofoil leading edge will be remained
Accumulated ice separation it is shatter, and ice is removed under airflow function.The transition position in region and air bag deicing region is sprayed in anti-freeze fluid,
Present invention employs inclined-plane processing modes, it is ensured that transitional region will not generate accumulated ice.In terms of control sequential, according to the different wings
The anti-deicing scope in face, suitable control sequential known to selection so that spray the shadow that the coverage of anti-freeze fluid works from air bag
It rings, and ensures that transitional region can all be covered by anti-freeze fluid.
Advantageous effect：
The more similar anti-freeze fluid anti-icing system of this anti-deicing system weight of combined type anti-freeze fluid-air bag of the present invention is light, right
Aerofoil aeroperformance is small compared with similar air bag deicing system.And this combined type anti-freeze fluid-anti-deicing system of air bag of the present invention,
Ensure that aerofoil costa is nearby influenced without icing, aerofoil leading edge rear accumulated ice by anti-freeze fluid, accumulated ice bond strength declines, gas
Capsule deicing efficiency greatly improves, and is integrally improved the anti-deicing efficiency of aerofoil, adds the Flight Safety Margin under freezing environment.
