Abstract:

Runway icing poses a threat to the safety of aircraft ground operation, accurate prediction of pavement temperature
and icing state is essential. To overcome the limitations of traditional runway icing predication methods in handling
complex scenarios, limited data, and physical inconsistency, this study proposes a runway icing prediction method
based on physics-informed neural network (PINN). The model embeds multilayer structure heat conduction and
water-ice phase change mechanisms into a deep neural network, enabling precise prediction of temperature fields
and water-ice state under limited data. Experimental data from a self-designed icing simulation are used to compare the solution results of PINN with the finite difference method (FDM). Results show that the jointly driven data physics PINN reduces average prediction error of temperature by about 90% compared to FDM, with just 0.21 ℃,
which is able to reconstruct full-field temperature field from limited data. Furthermore, the study analyzes the
mechanisms of salinity lowers the freezing point, delays icing, and suppresses ice growth. These findings can provide a new technological path for runway icing prediction.
