Abstract

An aircraft tire having improved wear properties is provided. The tire includes a belt reinforcement structure (128) that provides a flatter crown and reduces localized tensions. The belt reinforcement structure includes at least two hybrid belt plies (130,132) having free ends that are positioned radially inward of at least one non-hybrid belt ply (134,136). The hybrid belt plies allow for reductions in the overall mass of the tire and improved thermal properties while still meeting requirements for burst pressure and size for aircraft tires.

Description

technical field [0001] The subject matter of the present invention relates generally to a pneumatic aircraft tire having specific reinforcements in the crown portion of the tyre. Background technique [0002] A tire suitable for use on an aircraft must be able to operate at high speeds and under heavy loads. Preferably, aircraft tires should also be able to withstand the abrasive conditions associated with repeated taxiing, take-off and landing. Such tires must also be manufactured within strict constraints regarding their necessary burst pressure, size and weight for use and storage on board an aircraft. [0003] Aircraft tires are typically inflated to a relatively high inflation pressure, such as 12 bar or greater. Such high inflation pressures and the conventional construction of the crown portion of the tire typically have provided a very circular profile, as viewed along the meridian plane. These circular profiles (including circular tread portions) tend to provide ...
