Anti-icing Properties of Blowing Rotating Spinner

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.
