Anti-icing Properties of Blowing Rotating Spinner

为研究吹气式旋转帽罩防冰特性,采用三维模拟技术对其进行数值分析,从流场、水撞击和积冰特性3个方面分析了吹气式旋转帽罩的防冰机理和效果,并利用防冰试验器开展了试验研究,从帽罩表面积冰厚度和范围两方面分析防冰情况,验证了在结冰环境下吹气式旋转帽罩的防冰效果。结果表明,吹气式旋转帽罩防冰结构具有良好的防冰效果。

In order to obtain the properties of anti-icing on the blowing rotating spinner,this paper analyzes the anti-icing principles and effects of the blowing rotating spinner in three aspects of air flow,impaction of water droplets and icing properties,using three-dimensional numerical simulation technology.Meanwhile,the experimental research is carried out using icing wind tunnel.The anti-icing conditions are analyzed from both of the icing thickness and range on the spinner surface,and the anti-icing effects of the blowing rotating spinner are validated in the icing environment.Above analysis shows that the anti-icing structure of the blowing rotating spinner has an excellent effect on anti-icing.
