| 中文摘要: |
| 对H40×14.5-19 24PR民用飞机轮胎进行优化设计。通过采取优化胎冠轮廓、提升胎面胶整体性能、增大可磨耗胎面胶厚度以及改进骨架材料和胎体结构等措施，轮胎的可磨耗胎面厚度增大了2.5mm，接地印痕面积提高了15.6%，平均接地压力降低了13.5%，正常起飞试验后的胎面和胎肩温度均显著降低，轮胎的综合性能提升非常明显。 |
| 英文摘要: |
| The design of H40×14.5-19 24PR civil aircraft tire was optimized in this study，in which the crown profile was modified，the tread compound with better properties was used，the thickness of the tread for abrasion was increased，and the reinforcing materials and carcass structure were improved.After the optimization，the tread thickness increased by 2.5 mm，the grounding contact area was increased by 15.6%，the average contact pressure was reduced by 13.5%，and the temperature in tread and tire shoulder was decreased significantly after normal takeoff test.The optimized tire showed greatly improved overall performance. |
