CROWN REINFORCEMENT FOR AN AIRPLANE TYRE

摘要

Airplane tire comprises working reinforcement (2) radially inside of tread (3) and radially outside of carcass reinforcement (4). working reinforcement (2) comprises working biply (21). The radially innermost working biply (21) has the greatest axial width (LT) and comprises two axial ends (E). Carcass reinforcement (4) comprises carcass layer (41). Distance (D) between axial end (E) of the radially innermost working biply (21) and its orthogonal projection (I) onto the radially outermost carcass layer (41) is at least equal to 8 mm. Distance (D′) between point (F) of radially innermost working biply (21), axially inside of axial end (E) at a distance (L) equal to 25 mm, and its orthogonal projection (J) onto the radially outermost carcass layer (41) is at most equal to the distance (D) and is such that angle (A) equal to atan[(D−D′)/L] is at least equal to 12°.
