摘要
空中积冰严重影响着飞机的飞行安全。文章基于大气环境再分析数据对飞机空中积冰情况进行定量表征,开展积冰成因分析,揭示积冰发生的季节性规律,预测积冰分布的范围。在此基础上,有针对性地提出飞机改航策略,用以引导飞机快速精准地避开及脱离积冰区,提高飞机飞行的安全性和效率,保障空中交通安全、高效地运行。
Air icing seriously affects aircraft’s flight safety.Based on the reanalysis data of atmospheric environment,this paper quantitatively characterizes aircraft’s icing intensity in the air,analyzes the causes of ice accretion,reveals the seasonal characteristic of ice accretion,and predicts icing distribution range.On this basis,rerouting strategies are put forward to guide aircrafts to avoid and leave the icing area quickly and accurately,so as to improve the safety and efficiency of aircraft flight and ensure the safe and efficient operation of air traffic.
