Embodiment 1

[0059] This embodiment is a solar radiation test system based on the equivalent of an infrared light source for aircraft testing, including:

[0060] The test support bench 1 is used to simulate the field test based on the red light source solar radiation test corresponding to the aircraft assessment surface, such as figure 2 , image 3 As shown, the material of the test support table 1 is made of plastic, and the test support table 1 includes:

[0061] The two support legs at the bottom,

[0062] The table top 2 fixedly connected with the tops of several supporting legs, the front surface of the table top 2 is provided with a first irradiance meter 7 and a first temperature sensor 9, and the central position of the front surface of the table top 2 is provided with five rotating joints 5 with top openings equidistant laterally. , the rotating joint 5 is rotatably connected with the table 2, the opening of the rotating joint 5 is provided with a magnet, and the top of the ma...

Embodiment 2

[0067] This embodiment is a solar radiation test method based on the infrared light source equivalent for aircraft testing based on the solar radiation test system based on the infrared light source equivalent for aircraft testing in Example 1, such as figure 1 shown, including the following steps:

[0068] S1, prepare standard sample 8

[0069] According to the typical characteristics of the aircraft area exposed to sunlight, including material, roughness, and color, a typical standard sample 8 is prepared. The size of the standard sample 8 is smaller than the size of the effective area of ​​a single infrared radiation lamp module in the laboratory;

[0070] S2, formulate the standard control spectrum of the field test:

[0071] In the natural environment of the field, the solar radiation test of the standard sample is carried out. The test time is selected as a hot summer, and the test site is selected as an open and unshaded flat ground to obtain the thermal effect of the ...

Embodiment 3

[0089] The difference between this embodiment and Embodiment 2 is:

[0090] Step S2-3 specifically includes the following contents:

[0091] S2-3-1. Preliminary data processing: The preliminary data sorting module eliminates the measurement data in rainy, cloudy, and windy weather conditions, and selects multiple sets of measurement data on sunny days to establish the corresponding assessment surface of each standard sample 8 in the field test period. Correspondence curves of daily time-irradiance, time-ambient temperature and time-standard sample 8 temperature, when there is an abnormal phenomenon in the curve for a long period of time, the measurement data in this period of time is excluded, and the measured data in this period of time is excluded. The time-irradiance of the test surface with an angle of 10° on the fifteenth day of the field test is as follows Figure 5 As shown, the time-irradiance of the sixteenth day is as Image 6 shown, with Image 6 For example, the...

Description

technical field [0001] The invention relates to the technical field of aircraft testing, in particular to a solar radiation test system and method based on the equivalent of an infrared light source for aircraft testing. Background technique [0002] The solar radiation test is a typical test to verify the environmental adaptability of industrial products, and is used to determine the thermal and photochemical effects of solar radiation on products. For military aircraft, the solar radiation test is a necessary test in the development process. It is generally carried out in the natural environment and artificially simulated laboratory environment. Among them, the laboratory test has controllable conditions, short cycle, and a series of reproducibility. It is the main means of verifying the adaptability of aircraft solar radiation environment in my country. [0003] For the analysis of the thermal effect of solar radiation, my country's military standard GJB150.7A "Laboratory...
