摘要
飞机积冰前后各项特性指标均会发生改变,对飞机飞行安全十分重要。但由于飞机积冰后结构模型模拟非常复杂,单纯采用理论解析方法难以准确可靠地给出积冰飞机数学模型;此外运用简化力学模型得到的经验公式往往与实际结果有较大的出入;采用试验手段又会造成时间和人力物力上的巨大消耗。文中提出一种模拟积冰飞机结构的验证模型,完成积冰前后飞机结构情况的对比分析。
The research on icing plane has very important status which is widely applied in many fields such as flight safety. The test method is a greatly complex technology, so it is difficult to reliably solve the actual situation of icing plane through the theoretical analysis. Because the ice shape is difficult to predict by simplification mechanical model which often has great errors with actual result, and adopting experience way often wastes lots of manpower and material resource. The test model is put forward to analyze the icing plane characteristics.
