The invention discloses a bias aircraft tire and a preparation method thereof, and relates to the technical field of aircraft tire design and manufacturing. The bias aircraft tire comprises a tire body layer, a first tire bead and a second tire bead, the tire body layer comprises a first reverse wrapping cord fabric layer, a first forward wrapping cord fabric layer, a second reverse wrapping cord fabric layer, a second forward wrapping cord fabric layer and a third forward wrapping cord fabric layer which are sequentially arranged from inside to outside, the end of the first reverse wrapping cord fabric layer is reversely wrapped with a first tire bead, the end of the first forward wrapping cord fabric layer is forward wrapped with a first tire bead, and the end of the second reverse wrapping cord fabric layer is reversely wrapped with a second tire bead. The end part of the second positive wrapping cord fabric layer positively wraps the second tire bead, and the end part of the third positive wrapping cord fabric layer positively wraps the first tire bead and the second tire bead at the same time. According to the invention, more cord fabric layers can be fixed on one tire bead under the condition that the number of the cord fabric layers and the structural strength of the tire body are not changed, so that a three-tire-bead structure can be optimized into a two-tire-bead structure, the number of the tire beads is reduced, and the width of the tire bead part of the tire and the overall weight of the tire are further reduced.
本发明公开的斜交航空轮胎及其制备方法涉及航空轮胎设计与制造技术领域,斜交航空轮胎包括胎体层、第一胎圈和第二胎圈,胎体层包括由内向外依次设置的第一反包帘布层、第一正包帘布层、第二反包帘布层、第二正包帘布层和第三正包帘布层,且第一反包帘布层的端部反包第一胎圈,第一正包帘布层的端部正包第一胎圈,第二反包帘布层的端部反包第二胎圈,第二正包帘布层的端部正包第二胎圈,第三正包帘布层的端部同时正包第一胎圈和第二胎圈。本发明在保证轮胎胎体帘布层层数和结构强度不变的情况下,可在一个胎圈上固定更多的帘布层,从而可将三胎圈结构优化为两胎圈结构,减少胎圈的数量,进而减少了轮胎胎圈部位的宽度和轮胎的整体重量。
