首先对飞机结冰的原因、危害以及风挡防冰的方法做了简单的概述,针对广泛应用的民用飞机平面风挡防冰热量耗散进行分析,阐述了每部分热量的用途以及计算方法,针对热载荷计算输入,确定了热载荷计算状态点的选取原则,并考虑了风挡玻璃加热时向内散热的热量。提出了一种风挡防冰热载荷的计算方法,计算结果与实际应用中的几类机型的风挡防冰加温功率基本相当。所述的方法可用于工程设计。
First of all, the reasons for the ice icing, hazards and methods of anti-icing windshield made a simple overview of widely used commercial aircraft flat windshield anti-icing heat dissipation analysis, describes the use of each part of the heat and calculation methods for heat Load calculation input, determine the calculation principle of thermal load state points, and consider the windshield heating heat dissipation inward. A method of calculating the thermal load of the windshield anti-icing is proposed. The calculation results are basically the same as those of the windshield anti-icing heating power of several models in practical applications. The method described can be used for engineering design.
