Computational analysis of skid resistance of aircraft tire on wet runway pavement with different groove depths
This study aimed to develop an integrated approach to evaluate the groove depth effect on water depths and skid resistance on runway pavement. Finite element modelling of tire-water-pavement interaction was developed to calculate pavement friction coefficient of aircraft tire. Spatial distribution of water film depth was obtained based on analytical modelling and validated with field measurements. The results show that the thicker water film depth and the smaller friction coefficient are expected with the smaller groove depth. The effect of groove depth becomes more significant in the region close to the centerline of runway. The non-uniform distribution of water film depth would cause different skid resistance encountered by aircraft tires and increase safety risk of landing when aircraft wander happens. The developed simulation approach can be used to determine the threshold of groove depth for maintenance treatment considering rainfall condition, aircraft operation, and geometry of runway.
