FLYGPLANSHJULS RULLMOTSTAND I TORR NYSNOE (ROLLING RESISTANCE OF AIRCRAFT WHEELS IN DRY SNOW)
The National Swedish Road and Traffic Research Institute has carried out measurements of the rolling resistance of an aircraft wheel caused by dry snow. The wheel was equipped with a tire of the dimension 12.50-16, which is used on aircrafts of types CV-440 and N-262. The measurements were carried out at a static wheel load of 38.800 N (3.960 kp) and a tire air pressure of 410 kPa (60 psi) and 550 kPa (80 psi) respectively. The speed during the measurements was 50 km/h. The rolling resistance seem to increase approximately proportionally to the increase of the snow depth at a constant tire air pressure. Increased tire air pressure causes a decrease of the rolling resistance. This effect indicates that tires with high air pressure should be used on aircraft wheels when taking off from snow-covered areas, even if the load on the wheels does not require a high tire air pressure.
