CN103963978A - Combined Ultrasonic and graphite deicing method - Google Patents

Abstract

The invention provides a combined ultrasonic and graphite deicing method, relates to airplane environment protection technologies, and solves the problems of poor deicing effect, high energy consumption and changed aerodynamic shape of a deicing object in the prior art. According to the technical scheme, the method comprises the following steps: uniformly coating a protection region of a deicing object with a graphite laying region connected with a power supply; during deicing, instantly electrifying the graphite laying region to thaw accumulated ice making contact with the graphite laying region to form a liquid layer; then, starting an ultrasonic generation device for removing accumulated ice in the protection region. The method has a good deicing effect, is low in energy consumption, does not change the aerodynamic shape of the deicing object, and can be applied in any field with deicing requirements.

Description

Super sonic and graphite compound deicing method

Technical field

The present invention relates to aircraft environment guard technology, relate in particular to a kind of super sonic and graphite compound deicing method.

Background technology

As far back as twentieth century twenties, just start the anti-deicing technology of aircraft to study both at home and abroad, and constantly explore new efficient anti-de-icing method, and also constantly perfect to original anti-de-icing method, all make great progress in these areas.Common anti-deicing technology has the anti-deicing technology of electric heating and air bag deicing technology etc. both at home and abroad.Wherein, the full machine energising of the anti-deicing Technology Need of electric heating, consumption of current is very large; Air bag deicing technology adopts piecemeal expansion deicing, easily has residual ice in the unexpansive region in gap each other, affect aircraft deicing effect, and air bag expand after the easy aerodynamic configuration of change aircraft.

Summary of the invention

The object of the invention is: provide a kind of super sonic and graphite compound deicing method, the aerodynamic configuration that deicing is effective, power consumption less, does not change deicing object.

Technical scheme of the present invention is: a kind of super sonic and graphite compound deicing method, comprising:

Zone of protection at deicing object evenly applies graphite laying work area, and described graphite laying work area connects power supply;

In the time of deicing, the instantaneous energising of described graphite laying work area, melts the accumulated ice contacting with graphite laying work area, forms liquid level;

Start ultrasonic generator and remove the accumulated ice of zone of protection.

The invention has the beneficial effects as follows: this compound deicing mode does not have water droplet and flows and form overflow ice to trailing edge, affects deicing effect; In addition, deicing object is just melted near a fraction of ice inside covering, compares conventional anti-deicing mode and more saves energy; And the present invention is without the aerodynamic configuration of changing deicing object.

Brief description of the drawings

Fig. 1 is super sonic of the present invention and graphite compound deicing method flow diagram.

Detailed description of the invention

Below in conjunction with accompanying drawing, the present invention is described in further detail:

The invention provides a kind of super sonic and graphite compound deicing method, as shown in Figure 1, comprising:

S101, evenly apply graphite laying work area at the zone of protection of deicing object, described graphite laying work area connects power supply.

S102, in the time of deicing, the instantaneous energising of described graphite laying work area, melts the accumulated ice that contacts with graphite laying work area, forms liquid level.

S103, startup ultrasonic generator are removed the accumulated ice of zone of protection.

The present invention can be applied on aircraft, apply one deck graphite at the zone of protection of aircraft as the leading edge of a wing, utilize the electric conductivity heating of graphite, be characterized in that graphite heating is rapid, and cooling also fast, do not have too much energy to conduct heat to structural skin, only need form very thin liquid level by separating tactile ice-out with zone of protection surface, slackened the adhesive ability of ice and aircraft, restarted ultrasonic generator, the power producing in conjunction with super sonic just can easily be removed ice.Super sonic is uploaded sowing time at aircraft components, is divided into Lamb ripple and horizontal shear wave, and these two kinds of ripples are in the time of different in nature Propagation, can on the interface of different objects, produce velocity contrast, thereby generation shear stress field, in the time that this stress field is enough large, just can reach the object of deicing.The present invention is except aircraft, and can also be applied to steamer etc. has the field of requirement to deicing.
