Description
Technical field
The present invention relates to a kind of novel anti-deicing coverings in subregion, belong to the anti-deicing field of aircraft.
Background technology
Aircraft icing serious threat flight safety, can decline airplane ascensional force to a certain extent, and resistance increases.For civilian
For passenger plane, on the one hand freezing influences flight safety, the fuel consumption that the traditional anti-deicing system of the opposing party will increase aircraft.It is right
In military aircraft, such as unmanned plane, transporter etc., its flight range will directly be limited by freezing, its fight capability of strong influence.It passes
Anti- clearing ice technology such as pneumatic type, air heating type, electrothermal etc. of system can not meet future aircraft growth requirement.In recent years, correlation is ground
Study carefully and show that super hydrophobic surface has certain anti-icing ability, however rely on super hydrophobic surface merely and carry out its anti-icing effect and pay no attention to
Think, the delay time that freezes is relatively limited, and after super hydrophobic surface icing, icing will increase sharply.Simple super-hydrophobic surface layer
Compound mode, larger to power requirement with electrothermal layer, and for aerofoil profile different zones, heat needed for anti-deicing is different, therefore this
Invention proposes a kind of novel anti-deicing electric heating covering partitioned organization.
Invention content
For the aircraft that the energy is relatively nervous, the present invention proposes a kind of anti-deicing electric heating of low-power consumption suitable for the leading edge of a wing
Stressed-skin construction, to solve the disadvantage that power consumption is larger in a manner of the anti-deicing of existing electric heating.
In view of different types of wing, its characteristic size differs greatly, but for common icing, icing ice
Type is mostly wedge-shaped ice, as shown in Figure 1, this is mainly due to caused by the drop collection coefficient difference of aerofoil surface different location.
A kind of anti-deicing covering in novel subregion is devised accordingly, and the novel anti-deicing covering in subregion includes linking together super
Hydrophobic layer and electric heating layer are divided into five regions.As shown in Fig. 2, region 1 is located at position among covering, it is mainly used for machine
The anti-deicing at nose of wing place in line, power density is higher, and region 4 and 2 is located at the both sides up and down in region 1 respectively, is mainly used for
The higher position of leading edge of a wing drop collection coefficient, power density are relatively low compared to region 1, and region 5 and 3 is located at covering area respectively
The upside in domain 4 and the downside in region 2 only have super-hydrophobic effect, without heating power, are mainly used for preventing lower aerofoil on wing
The overflow ice at rear.
Further, the surface super hydrophobic layer carries PI layers of the polyimides of micro-nano structure surface, and on micro-nano structure
Modify low-surface energy substance.The low-surface energy substance be fluorochemical, such as perfluorobutyric acid, fluorine chloro pentane acid, containing fluoroalkyl
Sodium sulfonate, perfluor oxaamides based quaternary ammonium salt etc..
Further, the electric heating layer of the novel anti-deicing electric heating covering in five regions is by being connected in parallel.
After the present invention takes above-mentioned subregion, the capacity usage ratio of this design anti-deicing of its covering is higher, you can realizes
The energy-efficient wing anti-ice of precision, subdivision formula is advantageously implemented low-power consumption solution aircraft and prevents and kill off ice problem.
The purpose of the present invention and other advantages can pass through the institute spy in the specification, claims and attached drawing write
The structure do not pointed out is realized and is obtained.
Description of the drawings
The present invention is further detailed below with attached drawing, but the embodiment in attached drawing is not formed to this hair
Bright any restrictions.
Fig. 1 is the most common wedge-shaped ice of aircraft wing；
Fig. 2 is the subregion schematic diagram of the anti-deicing covering in the novel subregion of the application；
Fig. 3 is that the novel subregion of the application anti-deicing covering pastes design sketch.
Specific embodiment
Covering pastes effect as shown in figure 3, being stayed near line for the leading edge of a wing, since drop collection coefficient is maximum, i.e.,
The water droplet that air-flow moves together is followed when encountering the leading edge of a wing, since the quality and inertia ratio air of water droplet are big, it is impossible to as sky
Makings point follows air-flow that aggressive bend occurs like that, and then hits the leading edge of a wing.Region icing is the most serious, needs higher
Anti- deicing power density, can play the role of more reliable anti-ice action when anti-icing, when deicing can also play hot knife, make leading edge
Icing Fast Segmentation is opened.As air-flow is moved to trailing edge, drop collection coefficient also reduces therewith, is prevented and kill off to realize
Ice, region 2 and 4 need certain electrical heating power to act synergistically with super hydrophobic surface, work.Lower aerofoil is most on wing
After high point, due to directly being hit almost without water droplet, the overflow ice problem at the position is mainly considered, therefore devise region
3 and 5, this two pieces of regions can realize the anti-ice action of overflow ice merely with the superhydrophobic characteristic of covering without heating.
Anti- deicing electric heating covering that the present invention designs can effectively meet aircraft wing, empennage, rudder face and paste,
And there is the features such as construction is convenient, easy to use, the service life is good.
