AIRCRAFT RADIAL TIRE

摘要

A pneumatic radial aircraft tire is described having a B/A ranging between 60-70%. The tire may further optionally include a tire bead portion having a Ra/Fr1 relationship which ranges from about 1 to about 2.1. The tire may further optionally include a SW/TS ratio which ranges from about 0.1 to about 0.5, wherein SW is the chafer gauge at area A, TS is the total sidewall rubber gauge at area A, wherein A is defined as the region in the sidewall that has a lower radial endpoint defined by the point of contact between the flange and the tire at inflated, unloaded condition, and an upper radial endpoint AH defined by the tire wheel flange point of contact when the tire is at inflated, and at 200% rated load.

1. A pneumatic aircraft tire having a radial carcass, tread, a crown reinforcement comprising one or more belt layers or strips reinforced by cords oriented relative to the circumferential direction at an angle of between 0° and 45° with respect to the equatorial plane of the tire, and the B/W ratio of the tire ranges between about 0.6 to about 0.7, wherein B is the width between the wheel flange, and W is the section width under rated pressure, and the B/BW ratio ranges from 0.84 to about 1, wherein Bw is the maximum belt width.
