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。
First of all, a method to calculate the equivalent time of converting actual icing conditions to maximum icing condition based on the liquid water content scaling factor is introduced. Based on this, the influence of icing cloud layer extension length on the liquid water content is proposed A new calculation method of ice equivalent time is given and a calculation example is given. The results show that this method increases the calculation weight of partial equivalent time factor of high liquid water content and can more accurately reflect the requirements of the maximum icing conditions in airworthiness regulation.
