机载雷达天线单元耐久试验时间要求为12.5 h,条件苛刻。通过对天线单元样件开展耐久试验,验证样件承受耐久试验的能力,然后依据样件试验结果改进正样设计,进而确保天线单元正样顺利通过耐久试验。实践证明,先样件后正样的方法合理有效。 Airborne radar antenna unit durability test requirements for 12.5 h, harsh conditions. By carrying out endurance tests on antenna element samples, verify the ability of the sample to withstand endurance tests and then improve the positive design based on the sample test results to ensure that the antenna elements pass the endurance test smoothly. Practice has proved that the first kind of sample after the method is reasonable and effective.
