摘　　要：采用冰风洞模拟实验的方法对旋转整流罩表面的积冰过程进行了研究.积冰实验装置的主体部分位于冰风洞实验段内,驱动部分在外部,采用皮带传动.通过实验得到了旋转整流罩在典型结冰条件下的积冰生长特性:开始阶段积冰生长比较缓慢,沿旋转整流罩表面分布均匀,主要为透明的明冰;然后在明冰表面出现分布不连续的白色霜冰,其形状类似"羽毛"状,生长速度较快,最终旋转整流罩表面的"羽毛"状霜冰还发生了脱落现象.The ice accretion on the rotating spinner was tested in the icing wind tunnel. The main portion of the icing equipment was installed in the test section of the icing wind tunnel, driven by the external portion with strap. The ice accrection characteristics on the rotating spinner were obtained through icing test under typical icing conditions. The test results showed that at the beginning, the ice accrection was relatively slow, resulting in evenly distributed glaze ice on the spinner surface. And then, the glaze ice was discontinuously covered with white rime ice like ＇feather＇ and grew rapidly. Finally, a majority of the ＇feather＇ shaped rime ice shed from the icing surface of the rotating spinner.
