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 process on the surface of the rotating fairing was studied by using ice tunnel simulation experiment.The main part of the ice accretion device was located in the experimental section of ice wind tunnel with the driving part outside and belt drive.The rotating The ice cap growth characteristics of the fairing under typical icing conditions: The initial ice accretion growth is relatively slow and evenly distributed along the surface of the rotating fairing, mainly of transparent clear ice; then the white frosted ice with discontinuous distribution appears on the surface of the clear ice , Its shape is similar to “feather” shape, rapid growth, the final rotating fairing surface “feather ” shape frost ice also took off.
