With the rapid development of Chinese aviation technology, the study of anti-icing and de-icing technology is come to front, and the icing detector plays a crucial role in the effectiveness of anti-icing and de-icing. An ice detector based on the magnetic induction principle is analyzed. A calculation method of the related parameters is deduced through modeling and proved through a simulation experiment. The problem of calculating the basic parameters of the ice detectors is solved, and an effective method for designing an icing detector is provided.
