The invention relates to a cap ply structure of a meridian aircraft tire and the meridian aircraft tire, and the cap ply structure of the meridian aircraft tire comprises a reinforced cord fabric layer, a tire body layer and a tire crown area, the reinforced cord fabric layer comprises a first belted layer, a second belted layer and a third belted layer. According to the embodiment of the invention, the first belt strip is wound in the circumferential direction close to zero angle in a spiral manner, and the winding perimeter of each layer is set as s * n + (1/6-1/2) n, namely, the first layered structure is wound from the point O to the point D in the second direction and then wound by n/4 to reach the point F, and then the second layered structure is wound from the point F to the point G in the direction opposite to the second direction, then the third layered structure is wound from the G point to the H point in the axial direction, the fourth layered structure is wound from the H point to the O point, the first belted layer can enable the width of the first belted layer wound at each position of the tire body layer to be more uniform, and the first belted layer is more stable in the aspects of stress and the like.
本发明涉及一种子午线航空轮胎冠带层结构和子午线航空轮胎,其中,子午线航空轮胎冠带层结构包括:增强帘布层、胎体层、胎冠区域;所述增强帘布层包括:第一带束层、第二带束层以及第三带束层。本发明实施例中第一带束条螺旋方式周向接近于零角度缠绕,每层缠绕的周长设置为s*n+(1/6‑1/2)n,也即是第一层层状结构从O点以第二方向缠绕至D点后再缠绕多n/4以到达F点,然后第二层层状结构从F点以与第二方向相反的方向缠绕至G点中,然后第三层层状结构再依次从G点以轴向方向缠绕至H点,第四层层状结构从H点缠绕至O点中,该样设置的第一带束层能够使第一带束层缠绕在胎体层每个位置宽度更加均匀,使第一带束层在受力等方面更加稳定。
