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.
Claims13
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 85 W/mK;
- and
- wherein the cylindrical structure comprises:
- an outer layer;
- an inner layer;
- a middle layer between the outer layer and the inner layer and spaced apart from the outer layer by an air gap;
- a foil layer between the middle layer and the inner layer, the foil layer including dimples to maintain its position between the inner layer and the middle layer;
- and
- the inner layer defines an external inner diameter surface of the heat shield and the outer layer defines an external outer diameter surface of the heat shield.
