Edit | The implementation standard for ring instrument
airborne radar is "SJ 20115.3-1992 Airborne Radar Environmental Conditions and Test Methods Temperature Impact Test". The temperature shock test in the standard requires the use of a hot and cold shock test chamber to complete the temperature shock test between -55℃ and 70℃.
Onboard radar temperature impact test:
Test equipment: three-box hot and cold impact test chamber
Equipment model: ring instrument HYTS-50
Test method: one-box method
1. The test prototype without packaging is placed in the test chamber according to the normal position in the use state. The temperature of the test chamber is cooled down to -55℃, the placement time is t1, and the temperature stabilization time is t3;
2. The temperature of the test chamber is warmed up to 5±1 ℃/min, and the placement time is temperature stabilization time t3;
3. The temperature of the test chamber is cooled down to 5±1 ℃/min, and the temperature stabilization time is temperature stabilization time t3;
3. The temperature of the test chamber is cooled down to 5±1 ℃/min, and the temperature stabilization time is temperature stabilization time t3;
3. At this point, the test process forms a cycle. Follow this cycle 3 times. After the cycle is over, the sample is taken out of the test chamber and placed at room temperature for at least 2 hours. After the temperature is stable, the final test is performed.
airborne radar is mainly used to control and guided weapon , implement air alert and reconnaissance, and ensure accurate navigation and flight safety. Therefore, airborne radar will be significantly affected by temperature during use, so environmental testing is indispensable.
Many people have questions about why the three-box cold and cold impact test chamber is called the "one box method"? Because the three-box cold and cold impact test chamber has only one box in the test area, and the other two boxes are low-temperature boxes and high-temperature boxes. However, these two boxes are used to store high and low temperatures, and the test is in the test area, so we call this the "one box method".
