Abstract: Aircraft landing safety under wet conditions has been the focus of research in the field of aviation safety. Based on the main wheel of Airbus A320 aircraft, a aircraft tire model with different tread pattern characteristics and the refined tread pattern model were developed. Using optical scanning and 3D reconstruction, a runway surface model with gradation of SMA-13 asphalt mixture was constructed. Combined with Heinrich contact algorithm between rubber and rough runway surface was obtained, and the contact model between tread rubber and runway surface was developed. The Coupled-Eulerian-Lagrange (CEL) algorithm was used to solve the fluid-solid interaction between water film and runway surface and aircraft tire. Based on the proposed finite element model, the influence of aircraft landing speed, water film thickness, tire load, tread pattern and tire pressure on the hydroplaning was analyzed by the contact force between the runway surface and the tire and the hydroplaning speed.

Key words: aircraft tire hydroplaning, real texture, wet runway, hydrodynamic pressure, 3D reconstruction of runway surface
