Aircraft tire is an important subassembly of aircraft, which is related to its
safety tightly, especially for civil aircraft. Moreover, hydroplaning of aircraft tires is
often a contributing factor in take-off and landing overrun and veeroff accidents.
Therefore the study on them is imperative. A 2D finite element model of aircraft tire
is developed by using TYSYS software, and then a 3D patterned tire model is
presented. The hydroplaning of aircraft tire is analyzed by generally coupling an
Eulerian finite volume method and an explicit Lagrangian finite element method. The
hydroplaning speeds are investigated, which is a key factor of hydroplaning. Results
indicated that the hydroplaning speed increases with the increment of inflation
pressure; the hydroplaning speed decreases with the increment of the footprint aspect
ratio. |
