Aircraft water spray test on water-contaminated runway is of great significance in the civil aircraft airworthiness certification. In this paper, the differences in water spray between rolling elastic and rigid tires, and between the rolling and taxiing elastic tires, are studied. The smoothed particle hydrodynamics method is used for the numerical calculation of flowfield, the finite element method is used for the numerical calculation of the elastic tire structure, and the penalty method is used for the coupling interface between fluid and structure. Compared to the rolling rigid tire, the rolling elastic tire has a smaller splashing angle, lower water spray content, narrower strip of initial ejected particles, and a horseshoe-shaped footprint. Compared to the rolling elastic tire, the taxiing elastic tire has a larger splashing angle, higher water spray content, wider strip of initial ejected particles, and an oval-shaped footprint.
