[0002] Currently, there are various aviation equipments with different shapes, structures, materials and processes. When selecting an aviation equipment to use, multiple factors need to be considered to finally select an aviation equipment that meets the requirements. Among them, environmental factors are extremely important considerations when making a selection.

[0003] The existing method for selecting based on environmental factors requires environmental factor tests on aviation equipments that already meet other requirements (such as strength requirements). When the number of aviation equipments that meet other requirements is huge and the types of environmental factors to be tested are numerous, selecting an aviation equipment becomes an extremely time-consuming and inefficient task.

[0030] The following will describe the implementation methods of the present application in detail with reference to the accompanying drawings and embodiments, so that the implementation process of how the present application applies technical means to solve technical problems and achieve corresponding technical effects can be fully understood and implemented accordingly. The embodiments of the present application and the various features in the embodiments can be combined with each other without conflict, and the technical solutions formed are all within the scope of protection of the present application.

[0031] First, a corresponding table of "environmental profile - design parameters" needs to be established. The specific steps are as follows:

[0032] S101. First, according to the usage of aviation equipment, divide it into several different environmental profiles. For example, if the various usage states of aviation equipment are as Figure 1 shown, it can be roughly divided into several environmental profiles such as "outdoor parking", "hangar parking", "takeoff and landing environment", and "flight environment".

[0033] S102. Analyze the environmental factors that play a major role in each environmental profile. For example, in the harsh environment usage environment, in the several environmental profiles of "outdoor parking", "hangar parking", "takeoff and landing environment", and "flight environment" of aviation equipment, the main environmental factors are shown in the following table:

[0034]

[0035]

[0036] Table 1

[0037] S103. Select the environmental profile with the largest proportion in the time ratio for analysis. For example, select the "outdoor parking" environmental profile in the above table for main analysis.

[0038] S104. Establish a corresponding table of "environmental profile - design parameters";

[0039] The corresponding table contains multiple corresponding items, including environmental factor items, maximum or minimum values of environmental factors, maximum and minimum values including different risk probabilities, and device parameter items.

[0040] Among them, the values of environmental factors are obtained through quantitative analysis of environmental data such as meteorology and corrosive media collected. For example, collect the average temperature per hour within a specified number of hours (such as 744 hours), and analyze to obtain the maximum or minimum value of the temperature, and the maximum and minimum values of the temperature with different risk probabilities;

[0041] Among them, the risk probability refers to, for example, the percentage of a certain number of hours removed from the observed values within the specified number of hours (such as 744 hours) in extreme regions and extreme months. For example, if the highest or lowest value appears 7 hours in the 744 - hour observed values in a 31 - day month, then the occurrence time probability is 1%, and the 8th - ranked highest value / lowest value is the maximum / minimum value of the 1% risk probability. The risk probabilities of other percentages are the same.

[0042] Among them, the different risk probabilities corresponding to the parameters of the device parameter items indicate that if the device meets this item of parameter, it can meet the risk probability requirement. Meeting the risk probability requirement means that the device can operate stably in the extreme risk environment under the environmental factors as long as it meets this parameter, and the probability of failure is relatively low or there will be no failure.

[0043] As Figure 2 shown, a design method for an aviation equipment applicable to a harsh environment of the present application specifically includes the following steps:

[0044] S201: Determine the corresponding table of "environmental profile - design parameters" of the aviation equipment. Environmental profile.

[0045] For example, among the time ratios of the actual work and parking of the aviation equipment, the table corresponding to the environmental profile with the largest proportion can be selected, such as the "outdoor parking" environmental profile mentioned above;

[0046] S202: Confirm the risk probability requirements of natural environments such as temperature, relative humidity, solar radiation, and wind speed that the target aviation equipment needs to adapt to.

[0047] For example, if some equipment is more sensitive to temperature changes, it needs to be designed according to relatively strict high / low temperature resistance standards. For example, it is designed according to the maximum value at a 1% risk probability (such as being able to work normally at a temperature of 33.24 °C); while for some equipment that is not sensitive to temperature, it can be designed according to the maximum value at a 10% risk probability (such as being able to work normally at a temperature of 31.47 °C).

[0048] It should be noted that the service location of the aviation equipment determines its service environment, and the service environment determines the environmental factors. Therefore, it is necessary to confirm the environmental factors because it is necessary to ensure that the aviation equipment can operate safely and stably under various environmental factors in the service environment without risks and failures.

[0049] S203: According to the different risk probability requirements for different environmental factors, query the corresponding table of "environmental profile - design parameters" to obtain the design requirement parameters of the target device.

[0050] It should be noted that from the perspective of the corrosion environmental factors involved in the aircraft use environmental profile, if all are to be considered, the establishment of the "environmental profile - design parameters" is relatively difficult; at this time, the main environmental factors can be focused on for analysis. For example, for a harsh environment, the main environmental factors such as temperature, humidity, solar irradiance, and the deposition rate of CL ions in the air can be focused on.

[0051] S204: Design a corresponding aviation equipment as the target aviation equipment according to the design requirement parameters of the target device.

[0052] In addition, regarding the corresponding table of "environmental profile - design parameters" in step S104, an example is as follows:

[0053] For example, the corresponding table of "environmental profile - design parameters" applicable to a harsh environment includes the following parameters:

[0054] The maximum and minimum values of temperature, the maximum and minimum values of the maximum and minimum values of the risk probability at different percentages, the annual average temperature value, the monthly average highest temperature, and the monthly average lowest temperature;

[0055] The maximum and minimum values of relative humidity, the maximum and minimum values of the risk probability at different percentages between the maximum and minimum values of the humidity, the annual average relative humidity, the monthly average highest relative humidity value, the monthly average lowest relative humidity value, the wetting time when the relative humidity is greater than or equal to 70%, and the annual cumulative value of the wetting time when the relative humidity is greater than or equal to 80%.

[0056] The maximum value of the ultraviolet irradiation intensity of solar radiation, the maximum value of the ultraviolet irradiation intensity at different percentages of risk probability, the maximum value of the total radiation of the solar radiation, the maximum value of the total radiation at different percentages of risk probability, the annual ultraviolet irradiation amount, the annual total radiation amount, and the annual sunshine hours.

[0057] The maximum value of wind speed, the maximum value at different percentages of risk probability, the annual average wind speed value, the monthly average highest wind speed value, the monthly average lowest wind speed value, and the wind direction statistical value.

[0058] The maximum value of rainfall, the maximum value at different percentages of risk probability; the annual rainfall, the maximum value of rainfall hours, the maximum value at different percentages of risk probability; the maximum and minimum values of the rainwater pH value, the maximum and minimum values of the risk probability at different percentages; the annual average rainwater pH value.

[0059] The maximum and minimum values of the air pressure, the maximum and minimum values of the risk probability at different percentages.

[0060] The maximum and minimum values of the chloride ion deposition rate, the maximum and minimum values of the risk probability at different percentages; the annual average deposition rate.

[0061] The maximum value of the monthly average amount of sulfur dioxide, the maximum value of the risk probability at different percentages; the annual average value of sulfur dioxide.

[0062] The maximum value of the monthly average amount of nitrogen dioxide, the maximum value of the risk probability at different percentages; the annual average value of nitrogen dioxide.

[0063] The maximum and minimum monthly cumulative values of water-soluble dustfall in the sedimentation amount of solid particles, the maximum and minimum values of the risk probability at different percentages;

[0064] The maximum and minimum monthly cumulative values of non - water - soluble dustfall in the sedimentation amount of the solid particulate matter, the maximum and minimum values of the risk probabilities of different percentages;

[0065] The mold strains; the determination of the environmental corrosion severity level.

[0066] For a more intuitive understanding of the technical solution, in some embodiments, the corresponding table of "environmental profile - design parameters" is shown in the following table:

[0067]

[0068]

[0069]

[0070]

[0071]

[0072] Table 2

[0073] From the above table, the corresponding relationships between items can be seen. When looking up the table, the corresponding results can be directly obtained according to the content to be searched.

[0074] After that, confirm the risk probability requirements of the natural environment such as temperature, relative humidity, solar radiation, and wind speed that the target aviation equipment needs to adapt to.

[0075] According to the risk probability requirements and the environmental profile of the aviation equipment, query the design requirement parameters of the target device.

[0076] According to the design requirement parameters of the target device, design the corresponding aviation equipment as the target aviation equipment.

[0077] It should be noted that environmental factors can also include other factors, such as dust, mold, etc. There are differences in environmental factors in different geographical locations. Taking the southern coastal area as an example in this application, the main environmental factors involved are temperature, humidity, solar radiation, and the sedimentation rate of CL ions in the air. Of course, some secondary factors are also included, but these four factors have the greatest impact and are the most important. If more accurate results are pursued, new environmental factors can be added according to needs, but the method remains the same.

[0078] In some embodiments, the confirmation of the risk probability requirements of the target aviation equipment according to the environmental factors includes:

[0079] Confirm the risk probability requirements according to the target function and installation location of the target aviation equipment.

[0080] It should be noted that due to the different installation locations or functions of aviation equipment, the degree of environmental impact they are subject to in the same environment will be different. For example, the degree of environmental impact on aviation equipment used on the surface of an aircraft and that on aviation equipment used inside an aircraft must be different. Internal aviation equipment is relatively less affected by rain, humidity and solar radiation than external aviation equipment. Therefore, the risk probability requirements for internal aviation equipment can be different from those for external aviation equipment, which can help save costs because aviation equipment that can generally cope with more severe environmental factors may be more expensive due to factors such as materials and processes.

[0081] In some embodiments, the process of establishing the comparison table of environmental factor risk probability and device parameters includes:

[0082] Collect historical data on temperature, humidity, solar radiation and CL ion deposition rate in the air at different locations;

[0083] Based on the historical data, the risk probability of temperature, humidity, solar radiation and CL ion deposition rate in the air at different locations is calculated;

[0084] Collect device parameters of different aviation equipment;

[0085] Conducting risk probability tests on temperature, humidity, solar radiation and CL ion deposition rate in the air for the different aviation equipment, and counting all aviation equipment that meet different risk probability conditions;

[0086] The device parameters of all aviation equipment that meet the different risk probability conditions, as well as the risk probabilities of temperature, humidity, solar radiation and CL ion deposition rate in the air at different locations are correspondingly established into a table.

[0087] It should be noted that the above mentioned application takes the coastal area as the service location as an example. Its environment is characterized by high temperature and high humidity all year round, long sunshine time, strong radiation, abundant rainfall, obvious monsoon and high salt fog. In order to make the collected environmental data more effective, scientific and reasonable when applied, statistical analysis of the original environmental data is carried out.

[0088] Statistical analysis of raw temperature and humidity data:

[0089] For temperature and humidity data, statistics are collected for daily average value, daily maximum value, daily minimum value, monthly average value, monthly maximum value, monthly minimum value, annual average value, annual maximum value, annual minimum value, etc., to form corresponding hourly temperature and humidity data statistics tables, monthly reports, annual reports, etc., and calculate the extreme value of risk probability.

[0090] Statistical analysis of solar radiation and sunshine hours data:

[0091] For the collected data such as total solar radiation, total ultraviolet radiation, sunshine hours, etc., calculate the monthly cumulative amount, annual cumulative amount, etc., and generate corresponding reports. Also calculate the extreme value of the risk probability.

[0092] CL ion deposition rate in the air,

[0093] Based on the statistical results of the changes in environmental factors in each month of this area for the collected historical data, its specific manifestations are as follows:

[0094] Temperature, the temperature is high and relatively stable throughout the year, the annual average temperature is between 16 °C and 21 °C, and the temperature difference between day and night is small.

[0095] Humidity, the relative humidity in each month is above 70%, the humidity is relatively high, the annual wetting time is 3330h (RH>80%) accounting for 38.1% of the whole year, the monthly average humidity is relatively uniform, the lowest is 73.3% (January), and the monthly wetting time is 184h; the highest is 80% (July), and the monthly wetting time is 408h.

[0096] Sunshine and solar radiation, the monthly minimum sunshine hours is 132h (December), and the monthly minimum total radiation is 307MJ / M 2 (December); the monthly maximum sunshine hours is 310.7h (May), and the monthly maximum total radiation is 756.5MJ / M 2 (April); the monthly average sunshine hours is 222h, and the monthly average total radiation is 547.8MJ / M 2 , the annual cumulative sunshine hours is 2664h, and the annual cumulative total radiation is 6573.1MJ / M 2 . Compared with other regions, the total amount of sunshine and solar radiation in this region is relatively high.

[0097] CL ion deposition rate, maximum CL deposition rate: 6.508mg / 100cm 2 d, minimum CL deposition rate: 0.104mg / 100cm 2 d.

[0098] Therefore, taking the service area as an example of a harsh environment, the above four environmental factors have a greater impact on aviation equipment.

[0099] Finally, after obtaining the device parameters, it is easy to find the aviation equipment that meets the parameters during this period for service in the target area, and quickly complete the selection of the target aviation equipment.

[0100] In summary, the embodiment of the present application provides a method for selecting aviation equipment, including: obtaining the service environment of the target aviation equipment; confirming environmental factors according to the service environment; confirming the risk probability requirements of the target aviation equipment according to the environmental factors; querying a pre-established comparison table of environmental factor risk probability and device parameters according to the environmental factors and the risk probability requirements to obtain target device parameters; obtaining corresponding aviation equipment as the target aviation equipment according to the target device parameters. The present application can quickly determine the target device parameters in combination with the target service environment factor risk probability requirements of the aviation equipment through the pre-established comparison table of environmental factor risk probability and device parameters, and obtain the target aviation equipment that meets the requirements through the target device parameters. The selection method is efficient, fast, and time-saving.
