Take the square root of this value 4. … Web27 apr. 2014 · This equation gives an approximation of the minimum speed necessary to hydroplane on a smooth, wet surface with tires that are bald or have no tread. For example, the minimum hydroplaning speeds for an aircraft with tires inflated to 49 PSI are calculated as: Non-rotating tire:7.7 X √49 = 54 kt; or Rotating tire: 9 X √49 = 63 kt

WebBased on hydrodynamic theory, a simplified equation has been developed to predict the hydroplaning speed of a pneumatic tire; namely, Vp = 10.2 V P> where Vp = hydroplaning speed in miles per hour and p == tire inflation pressure in pounds per square inch. For example, a tire pressure of 16 pounds gives a hydroplaning WebAs the water’s resultant temperature rises, it creates a cushion of steam over which the aircraft is capable of hydroplaning. This is known as reverted- rubber hydroplaning. …
WebNine times the square-root of your tire pressure equals the vehicle hydroplane speed in mph. Example: Tire pressure of 36 psi Square root of 36 = 6. 9 times 6 = 54 mph. Easy, huh? Try another: Tire pressure 32 psi. Square root of 32 = 5.66 9 times 5.66 = 50.9 mph WebJohn D. Collins on May 20, 2012. The speed that an aircraft tire will hydroplane is determined by the tire pressure. To calculate the speed, multiply the square root of the …
WebBecause of this, the research has been done using aircraft tires which have very different characteristics from automobile tires. It is the objective of this study to observe what occurs at lower ... speed at which total hydroplaning begins. This equation assumes the 2 . load on the tire to be in equilibrium with the dynamic pressure in ... WebHydroplaning: Dynamic Hydroplaning: Dynamic hydroplaning occurs when standing water on a wet runway is not displaced from under the tires fast enough to allow the tire to make pavement contact over its total footprint area The tire rides on a wedge of water under part of the tire surface
