Y7-200A飞机自然结冰飞行试验

介绍了Ｙ７－２００Ａ飞机防冰除冰系统，自然结冰飞行试验所需气象专用设备和机场气象条件的选择以及自然结冰的飞行安全。同时还介绍了飞行试验的内容、试验方法及试验结果，并对试验结果进行了分析，试飞结果表明，带自然积冰飞机性能比带模拟冰型的好，自然结冰试验与模拟冰型试验之间的飞机操纵特性没有不可接受的差异，飞机飞行品质良好。可供运输类飞机自然结冰飞行试验时参考。

Natural Icing Flight Test for Y7-200A Aircraft

This paper presents the anti icing and deicing system, special meteorological equipment and selection of airfield meteorological condition for natural icing flight test, and flight safety of natural icing flight test.Meanwhile, the contents, methods and results of flight test are introduced in it. Flight test results indicate that aircraft performance with natural ice is better than that with simulated ice shape,and that the differences of aircraft controllability between natural icing flight test and simulated ice shape flight test aren't unacceptable. This paper can be used as a reference for natural icing flight test of transport aircraft.
