Description

Technical Field

[0001] The present invention belongs to the technical field of defrosting equipment regulation, and particularly relates to a method and system for regulating the blowing air pressure of an aircraft defrosting vehicle. Background Art

[0002] Under cold climate conditions, frost formation on the aircraft surface will significantly increase flight resistance and affect aerodynamic performance, threatening flight safety. Traditional aircraft defrosting vehicles achieve defrosting by impacting the frost layer with high-pressure airflows. The core lies in efficiently removing the frost layer through reasonable regulation of the blowing air pressure, while avoiding damage to the aircraft surface. This process poses relatively high requirements for the real-time and precision control of air pressure.

[0003] Currently, the mainstream defrosting methods are mostly based on fixed air pressure modes or empirical manual adjustments. Although some technologies introduce single parameters such as ambient temperature and wind speed for fine air pressure adjustment, they lack real-time monitoring of the dynamic changes of the frost layer (such as the thickness change rate and displacement speed). Existing systems are difficult to quantify the correlation between the frost layer state and the blowing air pressure, resulting in lag or deviation in air pressure adjustment and affecting the defrosting efficiency.

Description of the Drawings

[0057] Figure 1 It is a flowchart of a method for regulating the blowing air pressure of an aircraft defrosting vehicle provided by an embodiment of the present invention.

[0058] Figure 2 It is a schematic structural diagram of a system for regulating the blowing air pressure of an aircraft defrosting vehicle provided by an embodiment of the present invention. Detailed Embodiment

[0059] In order to make the purpose, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, and are not used to limit the present invention.

[0060] The following describes the specific implementation of the present invention in detail with reference to specific embodiments.

[0061] As Figure 1 shown, a method for regulating the blowing air pressure of an aircraft defrosting vehicle provided by an embodiment of the present invention includes the following steps:

[0062] Step S10: Obtain the status data of the frost layer in the defrosting area of the aircraft, and generate a defrosting effect evaluation index; among them, the status data of the frost layer includes the frost layer thickness change speed and the frost layer displacement speed;

[0063] Step S20: According to the defrosting effect evaluation index, determine whether the blowing air pressure of the current aircraft defroster is reasonable;

[0064] Step S30: If the blowing air pressure of the current aircraft defroster is unreasonable, obtain the environmental data and blowing angle of the defrosting area of the aircraft, establish a blowing air pressure adjustment analysis model, and generate a blowing air pressure adjustment value; among them, the environmental data includes light intensity, temperature and wind speed;

[0065] Step S40: Adjust the blowing air pressure of the defroster according to the blowing air pressure adjustment value.

[0066] As a preferred embodiment of the present invention, the step S10 specifically includes the following steps:

[0067] S11: Obtain the frost layer thickness change speed, and generate a thickness change evaluation index;

[0068] S12: Obtain the frost layer displacement speed, and generate a displacement speed evaluation index;

[0069] S13: Generate a defrosting effect evaluation index according to the thickness change evaluation index and the displacement speed evaluation index.

[0070] As a preferred embodiment of the present invention, the generation method of the thickness change index is specifically as follows:

[0071] Obtain the frost layer thickness change speed, and generate a frost layer thickness remaining value according to the current frost layer thickness, the frost layer thickness change speed and the remaining spraying time in the defrosting area; the frost layer thickness remaining value refers to the difference between the current frost layer thickness and the product of the frost layer thickness change speed and the remaining spraying time in the defrosting area;

[0072] Generate a thickness difference according to the frost layer thickness remaining value and the thickness remaining threshold; among them, the thickness difference refers to the difference between the frost layer thickness remaining value and the thickness remaining threshold;

[0073] Generate a thickness change index according to the thickness difference; among them, the thickness change index refers to the ratio of the thickness difference to the thickness remaining threshold;

[0074] It should be noted that the thickness remaining threshold is a preset value, and its value is set by relevant personnel in the field;

[0075] In addition, the remaining spraying time in the defrosting area refers to the time required for the blowing point of the defroster to move out of the edge of the defrosting area on the aircraft surface; in addition, the blowing point of the defroster is real-time data;

[0076] In this embodiment, the final effect of the defrosting vehicle's spraying on the frost layer thickness is predicted by the change rate of the frost layer thickness. If there is still remaining frost layer thickness, while keeping the moving speed of the defrosting vehicle's spray nozzle unchanged, the defrosting vehicle can completely remove the frost layer in the defrosting area on the aircraft surface by changing the blowing air pressure of the spray nozzle; conversely, if the remaining value of the frost layer thickness is negative, it means that while keeping the moving speed of the defrosting vehicle's spray nozzle unchanged, the blowing air pressure of the spray nozzle enables the defrosting vehicle to completely remove the frost layer in the defrosting area on the aircraft surface and there is a surplus, resulting in energy waste and even possible damage to the aircraft surface;

[0077] Exemplarily, through the formula:

[0078]

[0079] Generate the thickness change index H speed ;

[0080] In the formula, H now represents the current frost layer thickness, V h represents the change rate of the frost layer thickness, T rem represents the remaining spraying time in the defrosting area, and H0 represents the remaining thickness threshold.

[0081] As a preferred embodiment of the present invention, the generation method of the displacement speed evaluation index is specifically as follows:

[0082] Obtain the frost layer displacement speed, and generate a displacement speed difference according to the frost layer displacement speed and the frost layer displacement speed threshold; the displacement speed difference refers to the difference between the frost layer displacement speed and the frost layer displacement speed threshold;

[0083] It should be explained that the frost layer displacement speed threshold refers to the maximum displacement speed of the frost layer without causing damage to the aircraft surface;

[0084] Generate a displacement speed evaluation index according to the displacement speed difference and the frost layer displacement speed threshold; the displacement speed evaluation index refers to the ratio of the displacement speed difference to the frost layer displacement speed threshold.

[0085] As a preferred embodiment of the present invention, the generation method of the defrosting effect evaluation index is specifically as follows:

[0086] Through the formula:

[0087] R = H speed *α + V eva *β;

[0088] Generate the defrosting effect evaluation index R;

[0089] In the formula, Hspeed represents the thickness change index, V eva represents the displacement speed evaluation index, α and β are both weight coefficients, and α + β = 1;

[0090] It should be explained that the values of α and β are set by relevant personnel in the field; the ways of their values include the analytic hierarchy process, experimental calibration method, expert consultation method, etc., and these value-taking methods are all prior arts and will not be elaborated here.

[0091] As a preferred embodiment of the present invention, the specific method for judging whether the blowing air pressure of the current aircraft defroster is reasonable is as follows:

[0092] Compare the defrosting effect evaluation index with the defrosting effect evaluation index threshold;

[0093] It should be explained that the defrosting effect evaluation index threshold is a set value, and its value is set by relevant personnel in the field;

[0094] When the defrosting effect evaluation index is less than or equal to the defrosting effect evaluation index threshold, it is determined that the blowing air pressure of the current aircraft defroster is reasonable; the smaller the defrosting effect evaluation index, the more reasonable the blowing air pressure of the current aircraft defroster;

[0095] When the defrosting effect evaluation index is greater than the defrosting effect evaluation index threshold, it is determined that the blowing air pressure of the current aircraft defroster is unreasonable; the larger the defrosting effect evaluation index, the more unreasonable the blowing air pressure of the current aircraft defroster;

[0096] If the blowing air pressure of the current aircraft defroster is reasonable, only relevant personnel need to carry out daily maintenance, and there is no need to adjust the blowing air pressure;

[0097] If the blowing air pressure of the current aircraft defroster is unreasonable, it is necessary to adjust the blowing air pressure of the aircraft defroster to prevent the defrosting efficiency from being reduced due to too small blowing air pressure of the aircraft defroster, or energy waste caused by too large blowing air pressure of the aircraft defroster, etc.; in addition, if the blowing air pressure of the aircraft defroster is too large to a certain extent, it may cause damage to the aircraft surface and result in irreparable losses;

[0098] As a preferred embodiment of the present invention, step S30 specifically includes the following steps:

[0099] S31: If the blowing air pressure of the current aircraft defroster is unreasonable, obtain the ambient temperature, ambient wind speed and blowing angle of the aircraft defrosting area; wherein, the blowing angle refers to the included angle formed by the blowing path and the surface of the aircraft defrosting area;

[0100] S32: Generate an ambient temperature evaluation index according to the ambient temperature; wherein, the ambient temperature evaluation index refers to the ratio between the ambient temperature and the frost layer melting point temperature;

[0101] It should be noted that the frost layer melting point temperature is the lowest temperature value required for the frost layer to transform from a solid state to a liquid state;

[0102] When the aircraft is flying at high altitude, due to the low temperature at high altitude, a frost layer may be formed; after the aircraft lands, if the ambient temperature is higher than the frost layer melting point temperature, the frost layer can melt by itself by absorbing heat from the environment within a certain period of time. If the ambient temperature is too high, it may not be necessary to use a defrosting vehicle; however, in the scenarios where a defrosting vehicle is used, it is generally a low-temperature environment. What is considered in this embodiment is the other effects of the ambient temperature on the frost layer, such as the hardness of the frost layer;

[0103] S33: Generate an ambient wind speed evaluation index according to the ambient wind speed and the ambient wind speed threshold; the ambient wind speed evaluation index refers to the ratio between the ambient wind speed and the ambient wind speed threshold;

[0104] It should be noted that the ambient wind speed threshold refers to the lowest ambient wind speed that can push the frost layer;

[0105] S34: Generate a blowing angle evaluation index according to the blowing angle; wherein, the blowing angle evaluation index refers to the ratio between the blowing angle and the standard blowing angle;

[0106] S34: Establish a blowing air pressure adjustment analysis model, and substitute the ambient temperature evaluation index, the ambient wind speed evaluation index, the current blowing air pressure, and the defrosting effect evaluation index into the blowing air pressure adjustment analysis model to generate a blowing air pressure adjustment value;

[0107] Among them, the expression of the blowing air pressure adjustment analysis model is:

[0108]

[0109] In the expression, ΔP represents the blowing air pressure adjustment value, P now represents the current blowing air pressure, Q T represents the ambient temperature evaluation index, Q S represents the ambient wind speed evaluation index, R represents the defrosting effect evaluation index, θ represents the blowing angle evaluation index, a1 and a2 are both proportionality coefficients, and a1 + a2 = 1;

[0110] It should be noted that the values of a1 and a2 are set by relevant personnel in the field themselves; the ways of their values include but are not limited to the expert consultation method, etc.

[0111] As a preferred embodiment of the present invention, the specific generation method of the ambient wind speed evaluation index is:

[0112] Through the formula:

[0113] Generate the environmental wind speed evaluation index Q S ;

[0114] In the formula, S now represents the environmental wind speed, S0 represents the environmental wind speed threshold, ΔK represents the wind direction angle difference, and K max represents the maximum wind direction angle difference; the wind direction angle difference refers to the angle difference between the wind direction angle and the blowing angle;

[0115] It should be explained that the maximum wind direction angle difference refers to the angle difference between the wind direction angle and the blowing angle when the wind direction angle does not affect the defrosting layer removal by the aircraft defrosting vehicle; for example, if the angle difference between the wind direction angle and the blowing angle exceeds 90°, the thrust generated by the blowing air pressure and the thrust generated by the environmental air flow (i.e., the environmental wind speed) will cancel each other out, and this thrust acts on the frost layer.

[0116] As Figure 2 shown, the present invention also provides a blowing air pressure control system for an aircraft defrosting vehicle, and the system includes:

[0117] A defrosting effect analysis unit, configured to obtain the state data of the frost layer in the aircraft defrosting area and generate a defrosting effect evaluation index; wherein, the state data of the frost layer includes the frost layer thickness change speed and the frost layer displacement speed;

[0123] A displacement speed analysis module, configured to obtain the frost layer displacement speed and generate a displacement speed evaluation index;

[0130] The blowing air pressure adjustment value generation module is used to establish a blowing air pressure adjustment analysis model, and substitute the ambient temperature evaluation index, the ambient wind speed evaluation index, the current blowing air pressure, and the defrosting effect evaluation index into the blowing air pressure adjustment analysis model to generate a blowing air pressure adjustment value.

[0131] The present invention realizes the precise control of the blowing air pressure by real-time monitoring of the frost layer thickness change speed and displacement speed, generating a multi-dimensional defrosting effect evaluation index, and constructing a dynamic adjustment model in combination with the data of ambient temperature, wind speed, and blowing angle; the present invention can not only adapt to different environmental conditions, significantly improve the defrosting efficiency, reduce energy consumption, but also reduce the risk of damage to the aircraft surface during defrosting by the defrosting vehicle.
