摘要:

利用3 a空中观测资料和机载仪器采集资料分析了影响飞机积冰的气象条件,总结了飞机积冰的一般规律。分析结果表明:飞机积冰在水汽充沛地域发生较多;通常飞机积冰形成于温度低于0℃的云中,出现积冰的温度范围在0 ~ - 11 ℃,而出现较强积冰的温度范围在- 1 ~ - 8 ℃;云中过冷水含量越大,积冰强度也越大。

关键词: 飞机积冰, 气象条件

Abstract:

Based on the three - year air observational data, the impact ofweather conditions on aircraft icingwas analyzed, and the general rules of aircraft icing was summed up to enhance flight safety and security. The results show that the aircraft icing frequently occurred in winter and sp ring, and mostly in the areaswith p lenty ofwater vapor; the aircraft icing usually formed in the cloud with the temperature range of 0 to - 11 ℃, and especialy in the range of - 1 to - 8 ℃;when there wasmore supercooled water in the cloud,the aircraft icing would be more intensive.

Key words: aircraft icing, weather condition
