摘要
应用试验台完成了某型飞机风挡加温系统的地面试验,对加温过程中风挡玻璃内外表面温度进行测量,并进行了传热分析。该试验将安装有风挡玻璃的机头放置于高空模拟舱内,相比传统玻璃加温试验更为直观和充分,能够有效验证系统性能。试验结果表明:风挡玻璃加温功率及加温均匀性满足系统要求,加温控制规律合理。
Ground test of an aircraft windshield heating system was done on the FAI’s high altitude simulated test module. The outer and inner surface temperature of the windshield was measured in real time and unsteady heat transfer analysis was done. The nose of the airplane with windshield was placed in the test module to simulate the real lfight condition. The results of the test verify that the uniformity and the quantity of the power fulifll the system requirement, and the heating law is reasonable.
