Hydroplanning, 3 types are…
Dynamic
Viscous
Rubber Reversion
Dynamic Hydroplanning
Tyre is lifted off the runway by water
Completely Supported by water
Occurs at a speed determined by: VP (KTS) = 9 * Square Root of the tyre pressure (psi)
Viscous Hydroplanning
Tyre cannot penetrate thin film of fluid
Normally in zones of rubber deposits (TDZ)
Proceeds dynamic hydroplanning
This is the reason for a firm touchdown when film of water is present in the TDZ
Rubber Reversion
Friction between tyres and surface generate heat
Heat combined with standing water produces steam
Steam lifts the tyre off the surface and on water
Proceeds dynamic hydroplanning
