COEFFICIENT OF FRICTION OF ICE AT HIGH SPEED--APPLICATION TO A HIGH SPEED TRAIN

The frictional forces caused by ice sliding on aluminum at speeds between 150 and 360 mph were investigated for normal pressures from 0.25 to 0.46 psi. This information then was applied to a high-speed train concept by placing a block of ice under a train at a station so that, as train and ice block slide on the track, the melting ice provided a lubricating layer. Ice thicknesses required for train runs of various distances at different speeds were determined, for example, an ice thickness of 24 in. was required for a 300-mile trip at 350 mph. The concept appears to be feasible. Heat-transfer effects between the track and the ice were not included in this work.
