THE DRAG OF A LARGE AND SMALL PNEUMATIC TYRE TRAVELLING THROUGH WATER, SLUSH AND SNOW,

Abstract

Tests were made with a 35 x 10-17 aircraft tyre using the heavy load test vehicle described in S and T Memo 8/63 and results were compared with those from a 13 in. diameter, 3 in. wide tyre in trials of a recently developed device, a slush drag meter, to measure the water equivalent depth of runway contamination. Trials were conducted at Bromma, Sweden, on natural snow and at Road Research Laboratory at Crowthorne and Bristol University on water and ground ice with the small tyre and slush drag meter, and at Crowthorne only with the aircraft tyre. Within the speed range of the tests (up to 90 ft/sec) it was found that drag varied linearly with velocity squared in water and ground ice with both tyres and with the small tyre in Swedish snow. With the small tyre drag per inch increased with depth but was constant with the large tyre. (Author)
