Description
Technical Field
[0001] The present application relates to the technical field of aircraft salt spray testing, and in particular to a three-dimensional modal salt spray testing chamber for aging of unmanned aerial vehicles in dry-wet alternating ambient light. Background Art
[0002] Salt spray is a major factor in the marine climate environment. The seawater is violently disturbed due to the rolling and pounding of waves in the ocean, and the splashing and fragmentation of seawater produce a large number of tiny droplets. The tiny droplets are dispersed in the atmosphere, flow with the air flow, spread everywhere, and form a dispersion system, thus forming salt spray. It has a great destructive effect on aircraft and various other products. It is mainly manifested in corrosion effects, electrical effects and physical effects.
[0003] For UAVs, the marine climate is the most severe climate, and most of the failures of their mechanical equipment and materials occur in this environment. Therefore, marine environmental adaptability testing, assessment and evaluation of UAVs, materials and components are an urgent need to ensure the full life cycle of UAVs flying in the marine environment.
[0004] The marine environment has many effects on the durability and performance degradation of drones. First, the salt spray in the marine environment will corrode the surface materials of drones. The chloride ions in the salt spray droplets on the aircraft shell may invade the surface of the shell when it dries, and further penetrate when it comes into contact with salt spray again. When it dries, the water will migrate outward and the salt will migrate inward; when it is wetted by seawater, the salt enters the glass fiber capillary pores in the aircraft shell in the form of a solution. Therefore, the erosion of aircraft in the marine environment includes surface capillary action and internal diffusion.
[0005] In addition, the lighting conditions in the marine environment also have an important impact on the performance and life of drones. Aircraft flying over the ocean are often affected by factors such as wind and sunlight, resulting in a dry surface. However, as the temperature and humidity in the marine salt spray environment change, the surface of the aircraft may become wet in the next moment. This alternating state of dryness and wetness will have a greater impact on the composite shell of the aircraft.
[0006] Specifically, traditional salt spray environment test simulations usually only consider the impact of long-term exposure to salt spray on materials, but do not fully consider the comprehensive effects of other important factors in the marine climate environment. In particular, traditional salt spray test methods fail to fully simulate the alternating dry and wet states of aircraft in real marine environments, as well as the complex corrosion mechanisms faced by shell materials.
[0007] In order to more accurately evaluate the durability and performance degradation of aircraft in the marine environment, it is necessary to further improve the salt spray test chamber and consider more environmental factors. In addition to factors such as salt spray deposition rate, fog particle diameter, temperature and humidity, the cycle and frequency of alternating between dry and wet, as well as factors such as light intensity and angle should also be considered. Such tests can more accurately simulate the actual situation of aircraft in the marine climate environment and evaluate its adaptability and reliability.
[0008] In addition, the degree to which the reflection of the water surface and the beach intensifies the light exposure should also be considered. In the marine environment, due to the reflection of media such as the water surface and the beach, the light will be refracted and reflected in different directions, thereby enhancing the exposure effect on the UAV. Especially under strong sunlight, various materials on the surface of the UAV (such as plastic, metal, etc.) will absorb a large amount of light energy, resulting in increased temperature, and may even cause problems such as deformation, damage or circuit failure of the fuselage. Therefore, when conducting durability evaluation in the marine environment, it is necessary to consider the impact of lighting conditions on UAV materials and components.
[0009] In summary, in order to more accurately evaluate the adaptability and reliability of aircraft in the marine environment, it is necessary to improve the salt spray test chamber and comprehensively consider a variety of environmental factors, such as salt spray deposition rate, fog particle diameter, temperature, humidity, dry-wet alternation cycle and light intensity, etc. Such tests can more comprehensively simulate the actual situation of aircraft in the marine climate environment, evaluate its durability, reliability and performance degradation, and provide more comprehensive protection for the flight of aircraft in the marine environment.

[0032] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.
[0033] In order to make the above-mentioned objects, features and advantages of the present application more obvious and easy to understand, the present application is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.
[0034] The dry-wet alternating environment light aging stereomodal salt spray test chamber for unmanned aerial vehicles includes a chamber body 12 and an electrical control device, wherein the electrical control device is used to control the working state of the entire test chamber. Through the control system, the working parameters and time of each part such as the mist environment humidification system, the ultraviolet lamp, and the fan can be adjusted to achieve precise control of the dry-wet alternating simulation test.
[0035] like Figure 1-4 As shown, the chamber 12 is used to perform a dry-wet alternating salt spray test on the test object; the electrical control device is used to control the working state of the entire test chamber; one side of the chamber 12 is connected to the electrical control device; the chamber includes a spray chamber 2 and a drying chamber 3, the spray chamber 2 is used to simulate the wet state in the marine environment; the drying chamber 3 is used to simulate the air-dried state;
[0036] A conversion door is provided between the spray chamber and the drying chamber to facilitate adjustment of the position of the storage platform between the two chambers.
[0037] The spray chamber 3 is provided with a mist environment humidification system 11 and a first ultraviolet lamp 81; the mist environment humidification system provided in the spray chamber is used to generate salt mist and evenly distribute it in the spray chamber. By controlling the working state and parameters of the mist environment humidification system, different salt mist concentrations and spray times can be simulated to meet different test requirements.
[0038] The drying chamber 3 is provided with an axial flow ventilation system 52 and a second ultraviolet lamp 82; the cabin body 12 is provided with a shelf assembly 10, the shelf assembly 10 includes a shelf support 101, a platform slide frame 102, and a storage platform 103, the shelf support 101 is used to support the platform slide frame 102, the storage platform 103 is arranged on the platform slide frame 102, and is used to drive the test object through the conversion cabin door 4 to change the wet or air-dried state; the position of the storage platform 103 can be adjusted as needed to adapt to different dry-wet alternation cycles. The test object is placed on the storage platform 103, and its performance changes under different simulated environments can be observed.
[0039] The air outlet of the axial flow ventilation system 52 faces the conversion door 4. When the conversion door 4 is opened, the axial flow ventilation system 52 starts to generate airflow to reduce the water vapor of the spray chamber 2 from entering the drying chamber 3 to maintain a dry state.
[0040] The first ultraviolet lamp 81 is mounted on the upper side wall of the spray chamber 2 and irradiates the shelf assembly 10 without shielding; the second ultraviolet lamp 82 is mounted on the upper side wall of the drying chamber 3 and irradiates the shelf assembly 10 without shielding; these ultraviolet lamps are used to simulate ultraviolet radiation in the marine environment, and emit ultraviolet rays to irradiate the surface of the test piece to observe its durability and performance degradation.
[0041] It is worth noting that when conducting salt spray tests, these UV lamps can be used to simulate the UV radiation in sunlight, including three bands: UVA, UVB and UVC. These UV bands have an important impact on the weather resistance and performance degradation of the surface materials of drones. By controlling the light intensity and exposure time of the UV lamp, different degrees of UV radiation exposure can be simulated to evaluate the material aging and performance degradation of drones in marine environments.
[0042] It should be noted that when setting up the UV lamp, it should be reasonably selected and set according to the lighting conditions in the actual marine environment. Factors such as light intensity, spectral distribution, and sun angle in different marine areas will have different effects on the materials and components of the drone in the marine environment. Therefore, according to specific needs, ensure that the lighting parameters of the UV lamp in the salt spray test chamber can accurately simulate the lighting conditions in the target marine environment.
[0043] A further improvement is that the mist environment humidification system 11 is installed at the geometric center position of the storage rack assembly 10 in the spray bin 2; the mist environment humidification system 11 is connected to the electrical control device through a line, and the mist environment humidification system 11 is used to generate salt mist and evenly distribute it in the spray bin 2 to simulate the wet state of the aircraft surface.
[0044] The mist environment humidification system 11 includes a spray tower, a nozzle, an air pipe, and a salt water pipe; the spray tower includes a spray tower cage, a spray tower spire, and a spray tower pipe. The spray tower cage and the spray tower pipe are fixed by a fastening nut. The spray tower cage and the spray tower spire are an integrated structure, and the spray tower spire is downward toward the spray tower pipe; at the same time, it is ensured that the tower spray tower spire does not contact the spray tower pipe, and the nozzle is fixed in the middle of the spray tower pipe by a fastening nut. The air pipe and the salt water pipe are both arranged at the bottom of the spray tower pipe. The air pipe and the salt water pipe are both hoses. In the optional embodiment of the present application, a silicone tube can be selected. One end of the air pipe is connected to the spray tower pipe, and the other end is connected to the air source. At the same time, an air pressure regulating valve is provided at the connection between the two to adjust the air pressure in the air pipe to avoid damage to the equipment due to excessive air pressure. One end of the salt water pipe is connected to the spray tower pipe, and the other end is connected to the salt water tank 6.
[0045] In an optional embodiment of the present application, the diameter of the sprayed mist particles can be controlled by adjusting the operating parameters of the mist environment humidification system 11. In addition, nozzles of different sizes can be set to control the size of the mist particles to simulate different marine environmental conditions. The operating parameters of the mist environment humidification system, such as pressure, flow rate, and spray time, can be adjusted according to the test requirements. Increasing the pressure and flow rate will cause the diameter of the mist particles to become larger, while reducing the pressure and flow rate will cause the diameter of the mist particles to become smaller. At the same time, nozzles of different sizes can be used to control the size of the mist particles, and a larger nozzle aperture will produce larger mist particles, while a smaller nozzle aperture will produce smaller mist particles.
[0046] In addition, the cabin 12 is also provided with a salt fog deposition monitoring device 7, which includes a salt fog collector and a salt fog deposition data collector; the salt fog collector is arranged in the spray bin 2, and is used to collect the salt fog in the spray bin 2; the salt fog deposition data collector is arranged on the outer wall of the cabin 1, and the salt fog deposition data collector is connected to the salt fog collector, and is used to display the salt fog deposition data. By collecting and analyzing these data, the salt fog deposition rate can be determined, and the test box can be adjusted to simulate different salt fog deposition rates.
[0047] It is worth noting that, in order to reduce the corrosion effect on the drying box, etc., a mist exhaust fan is provided in the spray chamber to quickly discharge the salt mist in the spray chamber 2 out of the spray chamber 2.
[0048] The demisting fan 51 is connected to one end of the spring tube, and the other end of the spring tube leads to the sewer, so as to prevent the salt mist discharged by the demisting fan 51 from corroding its own equipment or other equipment.
[0049] A saturation barrel 9 is also provided in the spray chamber 2, and the saturation barrel 9 is connected to a water level pipe, and the water level in the water level pipe should be at 4 / 5 of its own height. When the water level drops to 2 / 5, water should be replenished in time to prevent the test from being interrupted due to lack of water and affecting the test process.
[0050] In the salt spray test chamber provided in the present application, the spray chamber 2 and the drying chamber 3 are both provided with temperature control devices for controlling the temperature in the chamber 1; the temperature control devices are both connected to the electrical control device through a line. The temperature control device can provide an appropriate temperature to simulate the temperature conditions in the air-drying state.
[0051] A temperature control device is provided in the spray chamber 2 and the drying chamber 3, which can be connected to the electrical control device through a line to control the temperature and humidity in the test chamber. At the same time, a temperature and humidity sensor is installed in the test chamber to monitor the temperature and humidity in real time and adjust them through the electrical control device.
[0052] Set the timer to control the spray and drying time to simulate different alternating times between wet and dry. At the same time, adjust the spray intensity and the speed of the axial flow ventilation system to simulate different humidity and drying times.
[0053] By collecting data and parameter change patterns in the actual marine environment, such as seawater temperature, salinity and wave height, and combining them with the simulation parameters in the cabin 1, comparative analysis is carried out to further optimize the design and operating parameters of the cabin 1.
[0054] The dry-wet alternating salt spray test chamber provided by the present application was used for multiple tests. In Example 1, the salt spray deposition rate was set to (1.0-2.0) ml / 80 (cm2h), the diameter of the fog particles was within 1-5 μm, accounting for more than 85%, the temperature was 25°C, the ratio of spray time to drying time was 1:1; the same time in the spray chamber 2 and the drying chamber 3, and the transfer from the spray chamber 2 to the drying chamber 3 was one cycle. By setting the same salt spray deposition rate and fog particle diameter, the same temperature and the same test time conditions, the experimental results were observed, as shown in Table 1:
[0055] Table 1 Comparison table of salt spray test under the same test time and different dry and wet times
[0056]
[0057] It can be seen from Table 2 that when the salt spray deposition rate is 2.0ml / 80(cm 2 h), the diameter of the fog particles is 5μm (accounting for more than 85%), the temperature is 25℃, and the test is conducted for 72 hours (h). Under different dry and wet times in Test 1, Test 2, and Test 3, the salt spray test results of the tested objects are different, as follows:
[0058] In the first test, a 12-hour spray test was first performed in the spray chamber 2, and then a 12-hour drying test was performed in the drying chamber 3. This was considered a cycle and the cycle was repeated three times. At the same time, the light intensity of the first ultraviolet lamp in the spray chamber 2 and the second ultraviolet lamp in the drying chamber 3 was set at 500 W / m 2 ; Under these three dry-wet cycles, no obvious changes were observed on the surface of the test object, and the physical properties did not change;
[0059] In the second test, the spray test was first carried out in the spray chamber 2 for 6 hours, and then the drying test was carried out in the drying chamber 3 for 6 hours. This was considered a cycle and the cycle was repeated 6 times. At the same time, the light intensity of the first ultraviolet lamp 81 in the spray chamber 2 and the second ultraviolet lamp 82 in the drying chamber 3 was set at 500W / m 2 ; During these 6 cycles of dry-wet cycles, the surface color of the test object was observed to change slightly, but the physical properties did not change;
[0060] In the third test, the spray test was first carried out in the spray chamber 2 for 6 hours, and then the drying test was carried out in the drying chamber 3 for 6 hours. This was considered a cycle and the cycle was repeated 6 times. At the same time, the light intensity of the first ultraviolet lamp 81 in the spray chamber 2 and the second ultraviolet lamp 82 in the drying chamber 3 was set at 1000 W / m 2 ; After these 6 cycles of dry-wet cycles, it was observed that the surface color of the test object changed significantly, but the physical properties did not change.
[0061] In the third test, a 4-hour spray test was first performed in the spray chamber 2, and then a 4-hour drying test was performed in the drying chamber 3. This was considered a cycle, and the cycle was repeated 9 times. At the same time, the light intensity of the first ultraviolet lamp 81 in the spray chamber and the second ultraviolet lamp 82 in the drying chamber was set at 1000 W / m 2 ; During these 9 cycles of dry-wet cycles, it was observed that the surface color of the test object changed significantly, the physical properties changed, and fine cracks appeared.
[0062] It can be seen that increasing the number of alternations will better simulate the salt spray corrosion in the actual environment and can more comprehensively evaluate the durability of the material. Under such conditions, the surface of the sample will usually show more obvious corrosion, oxidation, and even peeling, and the physical properties will deteriorate more significantly.
[0063] It can be seen that the dry-wet alternating multimodal salt spray test chamber provided in this application can simulate the alternating dry and wet states of an aircraft in a real marine environment. By adjusting parameters and controlling the working state of each part, a comprehensive performance evaluation and durability test can be performed, providing a reliable basis for the design and material selection of unmanned aerial vehicles.
