摘要

基于分形几何的基本理论

采用结冰风洞实验与金相显微实验相结合的方法

对飞机结冰冰型的微结构特征进行了研究.采用计盒维数法对冰型微结构的分形维数进行了计算

获得了不同条件下前缘结冰及溢流结冰冰型的分形维数

并建立了冰型分形维数与结冰条件之间的关系.研究表明

来流温度和速度对冰型的微结构特征及其分形维数有着重要影响.来流速度越高或温度越低

冰型微结构分形维数越大

反之分形维数越小.在相同条件下

溢流结冰的微结构分形维数要低于前缘结冰.

Abstract

The ice-type microstructure characteristics of aircraft icing were investigated by combining icing tunnel and metallography tests based on the theories of fractal geometry.The fractal dimension of the ice-type microstructure was calculated by means of box-counting dimension method

and the relationship between the fractal dimension and the icing conditions was analyzed.The results indicate that the inflow temperature and velocity of the airflow have great influence on the fractal dimension of ice-type microstructure.The higher velocity or the lower the temperature means greater fractal dimension

and vice versa.Under the same icing conditions

the fractal dimension of runback icing is smaller than the leading edge icing.
