基于红外遥感气象信息的舰载机飞行安全性评估

Safety evaluation for carrier aircrafts based on infrared remote sensing meteorological information

为充分利用战场气象信息,提高舰载机飞行的战场安全性,在对红外遥感气象信息特点和优势进行分析的基础上,提出了舰载机在一定气象条件下的作战与训练使用的安全性评估模型。模型包括起降安全指数和往返安全指数两部分,分别分析了主要的相关因素,并根据作训实际提出了评估与拟合计算办法。对于起降安全指数,利用判断矩阵求取不同气象要素的合理权重,提出了独立的客观气象指数的概念并给出了计算方法,然后进行线性加权便可得起降安全指数;对于往返安全指数,则主要根据云雾对舰载机的掩护程度做为安全性计算的基本依据。

In order to make full use of meteorological information and to improve the safety index of the carrier aircrafts, based on an objective analysis for the features and advantage of meteorological information, a safety evaluation model was put forward for the use of carrier aircrafts under pure marine meteorological background. The model was composed of two parts, namely taking off landing safety index and the round-trip safety index. the main relevant factors and evaluation method were given according to the practical use, including the fitting formulas. For the taking off landing safety index, a judge matrix was used to determine the weight of different meteorological factors, a new concept ＂objective meteorological index＂ and it′ s way of calculation were firstly put forward, then, the taking off landing safety index can be calculated by the way of linear weight adding. For the round-trip safety index, the main calculation method was focused on the covering effect for the aircrafts of clouds and fog.
