Technical field

The invention belongs to the technical field of aircraft deicing equipment, and in particular relates to a wind guide equipment for deicing civil aviation aircraft.

Background technique

The clever design of each aircraft's wings ensures that the aircraft can generate lift and fly in the air, but as the aircraft climbs, ice may accumulate on the wings as the temperature rises and the temperature drops. The accumulated ice will not only increase the weight of the fuselage, but also interfere with the stability of the aircraft. Under normal circumstances, the aircraft will be de-iced when taking off, and a certain amount of antifreeze will be sprayed on the wings to ensure that the wings It will not freeze within 1 to 2 hours. However, ice will still form on the wings during flight, and the ice layer formed is relatively strong and difficult to peel off. At present, most airlines use de-icing trucks or some de-icing equipment to de-ice aircraft. De-icing trucks generally have their own heat source, while many de-icing equipment generally do not include a heat source part. This type of de-icing equipment usually uses the aircraft's own air conditioner as the heat source for the de-icing equipment to perform de-icing operations. There are still some problems with using only heating for de-icing operations: due to the large heating area, the required power consumption is high. Although the heat generated by the operation of the aircraft itself can be used for heating, there are still many times where additional use is required. Electricity for heating.

In order to make the above objects, features and advantages of the present invention more obvious and understandable, the present invention will be described in further detail below with reference to the accompanying drawings and specific embodiments.

Referring to Figures 1-11, the present invention provides a wind guide device for deicing civil aviation aircraft, including:

The de-icing wind guide structure 2 is provided at the front end of the wing 1. The de-icing wind 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. The fixed base 21 is provided with an ice-breaking slot along the length direction of the inner side. 2103.

By arranging the ice-breaking electric heating structure 26, the ice layer 3 formed at the front end can be broken. Referring to Figure 10, after the ice-breaking electric heating 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 will be broken. Melting, the melted liquid will flow to the upper and lower sides, but due to the low temperature, the melted liquid is dispersed by the air flow, and the water mist will condense into ice on the upper and lower sides, which will cause the ice layer 3 on the upper and lower sides to thicken. At this time, the jet diversion structure 25 ejects gas, and the bottom end of the thickened ice layer 3 outside the jet diversion channel 2102 is inflated. As the aircraft flies, as shown in Figure 11, the airflow generated by the wings will cause the ice to Layer 3 falls off in large chunks, thus breaking the ice.

The arrangement of several heat-conducting plug-in boards 2202 and several docking plug-in boards 2603 inserted into each other can provide a good thermal conductivity effect. Such an arrangement can allow the ice-breaking front edge plate 2203 to be made of a material with poor thermal conductivity effect.

To further optimize the solution, thermal conductive glue is applied between several thermally conductive plug-in boards 2202 and several docking plug-in boards 2603. The thermally conductive glue is preferably thermally conductive silica gel, which can well fill the gaps between several thermally conductive plug-in boards 2202 and several docking plug-in boards 2603, significantly improving the efficiency and effect of thermal conduction.

To further optimize the solution, the jet splitting structure 25 includes a jet splitting tube 2501. The jet splitting tube 2501 is inserted in the jet slot 2104.

The thin end 2303 of the guide bar is provided, and the thick end 2302 of the guide bar is provided at the end of the guide bar 2301 away from the jet slot 2104.

Multiple jet reversal channels are formed between several jet guide structures 23 so that the jet can be jetted in a certain direction to avoid turbulence in the jet airflow and ensure the deicing effect. The setting of the thin end 2303 of the guide bar can ensure the entry of gas, while the setting of the thick end 2302 of the guide bar can not only improve the sturdiness, but also narrow the outlet end of the multiple jet backflow channels. The jetted air flow is faster and more powerful.

To further optimize the solution, a number of ice-melting electric heating wire insulating slots 2101 are provided on the part of the fixed seat 21 located on one side of the jet diversion channel 2102. The ice-melting electric heating wire insulating slots 2101 are inserted with a diversion channel and ice-melting electric heating wire. 24. One end of several diversion channel ice-melting electric heating wires 24 close to the fuselage is electrically connected to an ice-melting electric conductor 2402 through a first connector 2401.
