Dynamic hydroplaning formula
WebSep 18, 2009 · The above formula applies only to "Dynamic" hydroplaning. Reverted rubber hydroplaning occurs when the tire is allowed to skid. Steam (from boiling water) develops and changes the surface characteristics of the rubber. This new surface characteristic doesn't do as well in stopping the aircraft. Finally, there is viscous … WebThe 2001 report NLR-TP-2001-216 Safety aspects of aircraft performance on wet and contaminated runways gives additional and updated information related to the NASA/Horne's equation. Have a look at chapter 2.3 Hydroplaning in this report and you will see that there are differences related to "spin-up", "spin-down" and radial tyres. Table 1 …
