Abstract
A heat shield for an aircraft wheel assembly is made of a heat shield material evenly distributed across the heat shield along both the circumferential and the axial directions. The heat shield material has a high thermal conductivity greater than 30 W/mK. In various embodiments, the thermal conductivity is greater than 85 W/mK. In this manner, thermal flux is maximized throughout the heat shield to distribute heat evenly across the heat shield in both circumferential and axial directions.
Claims20
A wheel assembly, comprising:
- a wheel having a rim and configured to rotate about an axis;
- a torque bar disposed radially inward of the rim;
- a heat shield disposed between the wheel and the torque bar, wherein the heat shield comprises a cylindrical structure extending circumferentially about an axis of the wheel and around an inner diameter of the rim;
- wherein the heat shield comprises a heat shield material, and a thermal conductivity of the heat shield material is greater than 30 W/mK.
A heat shield for an aircraft wheel assembly, comprising
- an outer layer;
- and
- an inner layer spaced apart from the outer layer;
- wherein at least one of the outer layer and the inner layer comprises a heat shield material evenly distributed across the heat shield, wherein a thermal conductivity of the heat shield material is greater than 30 W/mK.
A heat shield for an aircraft wheel assembly, comprising:
- a metal layer comprising a steel core and an aluminum coating covering the steel core.
