摘要
首先介绍了一种根据液态水含量比例因子计算实际结冰条件向最大结冰条件转换的等效时间计算方法,并在此基础上考虑了结冰云层延展长度对液态水含量的影响提出了一种新的结冰等效时间计算方法,并给出了计算实例。结果表明:该方法增加了高液态水含量部分等效时间因子的计算权重,能更真实的反映适航规章中最大结冰条件的要求。
Introduced an icing equivalent time calculation method from the ratio of measured and standard Liquid Water Content （LWC） to get the relation between the natural icing conditions to the maximum icing conditions. Then, a new icing equivalent time method was advanced based on the relation between extension range of icing cloud and LWC factor. An example was presented with two methods. The results show that, the new method can improve the power of higher LWC in the equivalent time calculation, and can reflect the airworthiness regulation more accuracy.
