Aircraft ground secondary icing early warning system and method under freezing rain environment
By using CFD numerical simulation data to drive an offline pre-built anti-icing liquid film failure model, combined with the characteristics of non-spherical raindrops and the analysis of multiple failure mechanisms, the accuracy and real-time performance of aircraft ground secondary icing warning under freezing rain conditions were solved. This enabled regional and graded warnings, improving the operational safety and efficiency of civil aviation airports.
