Description

Technical Field

[0001] This invention belongs to the technical field of aircraft de-icing equipment, and particularly relates to a de-icing air guide device for civil aircraft. Background Technology

[0002] The ingenious design of each aircraft's wings ensures that it generates lift for flight. However, during ascent, as altitude increases and temperatures drop, frost can accumulate on the wings. This accumulated ice not only increases the aircraft's weight but also interferes with its stability. Typically, de-icing is performed during takeoff, and antifreeze is sprayed onto the wings to prevent icing for 1-2 hours. However, icing can still occur on the wings during flight, and the resulting ice layer is often quite solid and difficult to remove. Currently, most airlines use de-icing trucks or other de-icing equipment for aircraft de-icing. De-icing trucks usually have their own heat source, while many de-icing devices do not. These devices typically utilize the aircraft's own air conditioning system as their heat source. However, relying solely on heating for de-icing presents several challenges: the large heating area requires significant power, and while the aircraft's own heat generation can be used, additional electricity is often necessary for heating in many situations.

[0003] Therefore, there is an urgent need for a device that can reduce the power consumption required for heating and improve the de-icing effect to solve this problem. Summary of the Invention

[0004] The purpose of this invention is to provide a de-icing device for civil aircraft to solve the above-mentioned problems, thereby effectively improving the de-icing effect by combining heating de-icing with air-guided ice breaking, and reducing the power consumption required for heating, thus saving energy.

[0005] To achieve the above objectives, the present invention provides the following solution:

[0006] A de-icing airflow device for civil aircraft, comprising:

[0007] A de-icing air guide structure is installed at the leading edge of the wing. The de-icing air guide structure includes a fixed base, the rear end of which is fixedly connected to the leading edge of the wing. An ice-breaking slot is provided on the inner side of the fixed base along the length direction. On the portion of the fixed base located on both sides of the ice-breaking slot, jet slots and jet guide channels communicating with the jet slots are respectively provided along the length direction. The end of the jet guide channel away from the jet slot is connected to the outside.

[0008] An ice-breaking electric heating structure is inserted into the ice-breaking slot. The ice-breaking structure is fixedly connected to the part of the fixed base located at the front end of the ice-breaking electric heating structure. The ice-breaking structure is in contact with the ice-breaking electric heating structure. The end of the ice-breaking electric heating structure near the body is electrically connected to the power supply structure. An air jet splitter structure is inserted into the air jet slot. The end of the air jet splitter structure near the body is fixedly connected to the air pump structure through a connecting air pipe.

[0009] Preferably, the ice-breaking electric heating structure includes an ice-breaking heating wire mounting post, which is inserted into the inside of the ice-breaking slot. An ice-breaking heating wire is fixedly connected along the length of one end of the ice-breaking heating wire mounting post near the ice-breaking structure. The ice-breaking heating wire is in contact with the ice-breaking structure. The end of the ice-breaking heating wire near the body is electrically connected to a main wire through a second connector. The main wire is electrically connected to the power supply structure away from the second connector.

[0010] Preferably, the ice-breaking structure includes an ice-breaking leading edge plate, which is fixedly connected to the front end of the fixed base. An ice-breaking docking groove is formed along the length direction on the side of the ice-breaking leading edge plate near the fixed base, and the ice-breaking heating wire is in contact with the ice-breaking docking groove.

[0011] Preferably, a plurality of docking plates are fixedly connected at equal intervals along the length direction at one end of the ice-breaking heating wire near the ice-breaking structure, and a plurality of heat-conducting plates are fixedly connected along the length direction inside the ice-breaking docking groove, with the plurality of heat-conducting plates and the plurality of docking plates being inserted and connected to each other.

[0012] Preferably, thermally conductive adhesive is applied between the plurality of thermally conductive inserts and the plurality of mating inserts.

[0013] Preferably, the jet splitting structure includes a jet splitting pipe, which is inserted into the jet slot. A main jet channel is formed axially inside the jet splitting pipe, and several branch jet channels are formed radially inside the jet splitting pipe. The several branch jet channels are arranged along the length of the jet splitting pipe and are connected to the main jet channel. A slot is formed axially at the end of the jet splitting pipe away from the main jet channel, and the several branch jet channels are connected to the jet guide channel.

[0014] Preferably, a plurality of jet guiding structures are fixedly connected along the length direction on the inner side of the jet guiding channel. Each jet guiding structure includes a guide strip, with a thin end near the jet slot and a thick end away from the jet slot.

[0015] Preferably, the fixed base has several ice-melting heating wire insulation slots on the part located on one side of the jet guide channel. Ice-melting heating wires for the guide channel are inserted into the ice-melting heating wire insulation slots. The ends of the several ice-melting heating wires near the fuselage are electrically connected to ice-melting wires through a first connector. The ends of the ice-melting wires away from the first connector are electrically connected to the main line through a transformer.

[0016] Compared with the prior art, the present invention has the following advantages and technical effects:

[0017] By incorporating an ice-breaking electrothermal structure, the ice layer at the front end can be broken. After the ice layer on the ice-breaking structure is broken, the ice at the front end melts, and the melted liquid flows to the upper and lower sides. However, due to the low temperature, the melted liquid is dispersed by the airflow, and the water mist condenses into ice on the upper and lower sides, causing the ice layer to thicken. At this time, the jet diversion structure ejects gas, inflating the bottom of the thickened ice layer outside the jet guide channel. As the aircraft flies, the airflow generated by the wings causes large chunks of ice to break off, thus achieving ice breaking. This invention achieves good ice-breaking results without requiring extensive heating equipment or high power consumption. Attached Figure Description

Detailed Implementation

[0031] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0032] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0033] Reference Figure 1-11 As shown, the present invention provides a de-icing air guide device for civil aircraft, comprising:

[0034] The de-icing air guide structure 2 is set at the front end of the wing 1. The de-icing air guide structure 2 includes a fixed base 21. The rear end of the fixed base 21 is fixedly connected to the front end of the wing 1. An ice-breaking slot 2103 is opened on the inner side of the fixed base 21 along the length direction. On the part of the fixed base 21 located on both sides of the ice-breaking slot 2103, jet slots 2104 and jet guide channels 2102 communicating with the jet slots 2104 are respectively opened along the length direction. The end of the jet guide channel 2102 away from the jet slots 2104 is connected to the outside.

[0035] An ice-breaking electric heating structure 26 is inserted into the ice-breaking slot 2103. An ice-breaking structure 22 is fixedly connected to the part of the fixing base 21 located at the front end of the ice-breaking electric heating structure 26. The ice-breaking structure 22 is in contact with the ice-breaking electric heating structure 26. The end of the ice-breaking electric heating structure 26 near the body is electrically connected to the power supply structure 2606. An air jet slot 2104 is inserted into the air jet splitting structure 25. The end of the air jet splitting structure 25 near the body is fixedly connected to the air pump structure 2505 through the connecting air pipe 2506.

[0036] By setting up the ice-breaking electric heating structure 26, the ice layer 3 formed at the front end can be broken, as shown in the reference. Figure 10 As shown, after the ice-breaking electrothermal structure 26 breaks the ice layer 3 on the ice-breaking structure 22, the ice layer 3 at the front end of the ice-breaking structure 22 melts. The melted liquid flows to the upper and lower sides, but due to the low temperature, the melted liquid is dispersed by the airflow, and the water mist condenses into ice on the upper and lower sides, causing the ice layer 3 on the upper and lower sides to thicken. At this time, the jet splitting structure 25 ejects gas, and the bottom end of the thickened ice layer 3 outside the jet guide channel 2102 is inflated. As the aircraft flies, reference... Figure 11 As shown, the airflow generated by the wings causes the three large chunks of ice to break off, thus achieving ice breaking. This invention achieves good ice breaking results without requiring extensive heating equipment or high power consumption.

[0037] The solution is further optimized. The ice-breaking electric heating structure 26 includes an ice-breaking electric heating wire mounting post 2601, which is inserted into the ice-breaking slot 2103. An ice-breaking electric heating wire 2602 is fixedly connected along the length of the end of the ice-breaking electric heating wire mounting post 2601 near the ice-breaking structure 22. The ice-breaking electric heating wire 2602 is in contact with the ice-breaking structure 22. The end of the ice-breaking electric heating wire 2602 near the body is electrically connected to a main wire 2605 through a second connector 2604. The main wire 2605 is electrically connected to the power supply structure 2606 away from the second connector 2604.

[0038] The ice-breaking heating wire mounting post 2601 is preferably made of insulating material. By setting the ice-breaking heating wire mounting post 2601, support and protection can be provided for the ice-breaking heating wire 2602. Since the ice-breaking heating wire 2602 and the ice-breaking leading edge plate 2203 are connected by several heat-conducting inserts 2202 and several mating inserts 2603, when disassembling the ice-breaking heating wire 2602, the ice-breaking heating wire mounting post 2601 can be removed first, and then the ice-breaking heating wire 2602 can be disassembled. An insulating layer is provided around the periphery of the ice-breaking heating wire 2602.

[0039] Further optimizing the design, the ice-breaking structure 22 includes an ice-breaking leading edge plate 2203, which is fixedly connected to the front end of the fixed base 21. An ice-breaking docking groove 2201 is formed along the length of the side of the ice-breaking leading edge plate 2203 near the fixed base 21, and the ice-breaking heating wire 2602 is in contact with the ice-breaking docking groove 2201. The ice-breaking leading edge plate 2203 is preferably made of insulating material to prevent damage to the insulation layer around the ice-breaking heating wire 2602, which could lead to an open circuit.

[0040] In a further optimized design, several docking plates 2603 are fixedly connected at equal intervals along the length of one end of the ice-breaking heating wire 2602 near the ice-breaking structure 22. Several heat-conducting plates 2202 are fixedly connected along the length of the ice-breaking docking groove 2201. These heat-conducting plates 2202 and docking plates 2603 are interlocked and connected to each other. This interlocking arrangement of heat-conducting plates 2202 and docking plates 2603 provides excellent heat conduction, allowing the ice-breaking leading edge plate 2203 to be made of a material with poor thermal conductivity.

[0041] In a further optimized design, thermally conductive adhesive is applied between several thermally conductive inserts 2202 and several mating inserts 2603. The thermally conductive adhesive is preferably thermally conductive silicone, which effectively fills the gaps between the thermally conductive inserts 2202 and the mating inserts 2603, significantly improving the efficiency and effectiveness of heat conduction.

[0042] Further optimization of the scheme: the jet splitting structure 25 includes a jet splitting pipe 2501, which is inserted into a jet slot 2104. A main jet channel 2502 is axially formed inside the jet splitting pipe 2501. Several branch jet channels 2503 are radially formed in the jet splitting pipe 2501. The several branch jet channels 2503 are arranged along the length of the jet splitting pipe 2501 and are connected to the main jet channel 2502. A slot 2504 is axially formed at the end of the jet splitting pipe 2501 away from the main jet channel 2502. The several branch jet channels 2503 are connected to the jet guide channel 2102.

[0043] In a further optimized design, several jet guide structures 23 are fixedly connected along the length of the inner side of the jet guide channel 2102. Each jet guide structure 23 includes a guide strip 2301. The end of the guide strip 2301 near the jet slot 2104 is provided with a thin end 2303, and the end of the guide strip 2301 away from the jet slot 2104 is provided with a thick end 2302.

[0044] Multiple jet guide structures 23 form multiple jet backflow channels, allowing the jet to be ejected in a certain direction, avoiding jet flow turbulence and ensuring the de-icing effect. The thin end 2303 of the guide strip ensures gas entry, while the thick end 2302 of the guide strip improves rigidity and narrows the outlet end of the multiple jet backflow channels, resulting in a faster and stronger jet flow.

[0045] In a further optimized design, the fixed base 21 is provided with several de-icing heating wire insulation slots 2101 on one side of the jet guide channel 2102. De-icing heating wires 24 are inserted into the de-icing heating wire insulation slots 2101. The de-icing heating wires 24 are electrically connected to the de-icing wires 2402 via the first connector 2401 at the end of the de-icing wires 2402 away from the first connector 2401. The de-icing wires 2402 are electrically connected to the main line 2605 via the transformer 2403.

[0046] The ice-melting heating wire 24 in the flow channel can melt the ice inside the jet flow channel 2102, preventing blockage, and the generated liquid can be discharged through jet.
