Abstract
A composite PDU tire in an aircraft cargo handling system may include a plurality of bonded regions configured to propel cargo within an aircraft cargo bay. The composite tire may include edge regions that are stiffer than a cylindrical region. The edge regions may be configured to have a greater wear resistance and abrasion resistance relative to the cylindrical region. The cylindrical region may be configured to have greater traction relative to the edge regions. The edge regions may include a fillet profile and may be configured to reduce chipping as cargo climbs across the tire.
Claims17
A composite tire, the composite tire comprising:
- a cylindrical region having a first circumferential groove and a second circumferential groove, an inner radial portion of the cylindrical region configured to couple to a first outer radial portion of a wheel;
- a first edge region having a fillet, wherein the first edge region is configured to axially couple to the first circumferential groove at a first bonding region and wherein an inner radial portion of the first edge region is configured to couple to a second outer radial portion of the wheel;
- and
- a second edge region having a fillet, wherein the second edge region is configured to axially couple to the second circumferential groove at a second bonding region and wherein an inner radial portion of the second edge region is configured to couple to a third outer radial portion of the wheel,
- wherein the first edge region and the second edge region comprise a first material and the cylindrical region comprises a second material, wherein the first material is stiffer than the second material, wherein the first material and the second material are different materials.
A tire assembly comprising:
- a composite tire bonded to a wheel, the composite tire comprising:
- a cylindrical region having a first circumferential groove and a second circumferential groove, an inner radial portion of the cylindrical region configured to couple to a first outer radial portion of the wheel;
- a first edge region having a fillet, wherein the first edge region is configured to axially couple to the first circumferential groove at a first bonding region and wherein an inner radial portion of the first edge region is configured to couple to a second outer radial portion of the wheel;
- and
- a second edge region having a fillet, wherein the second edge region is configured to axially couple to the second circumferential groove at a second bonding region and wherein an inner radial portion of the second edge region is configured to couple to a third outer radial portion of the wheel,
- wherein the first edge region and the second edge region comprise a first material and the cylindrical region comprises a second material, wherein the first material is stiffer than the second material, wherein the first material and the second material are different.
