Ice shape simplification method

The invention provides an ice shape simplification method, and belongs to the field of aviation. complex irregular two-dimensional ice shapes obtained in an ice wind tunnel are simplified, a B-spline method is adopted, for two basic types of ice of angular-type ice and streamline ice, a parametric description method based on ice shape characteristic point positions is provided, and an ice shape simplification method which seeks an optimal or quasi optimal scheme by taking ice shape similarity as a target function is disclosed. According to the method, technical support is provided for fields such as aircraft icing research, icing wind tunnel debugging, ice wind tunnel experiment result processing and the like, and good engineering application values are provided.
