This application provides a heat shield structure and installation method for aircraft wheels. The heat shield in this structure is a single-piece titanium alloy sheet, and the clamps are made of stainless steel. The heat shield is fixed between the guide rail cover and the guide rail boss of the wheel hub by the clamps, which improves the stability of the heat shield. In contrast, existing single-piece heat shields are too thin, making it impossible to press and fix the wheel and guide rail firmly. The single-piece heat shield will have limited movement between the wheel and guide rail, which will cause friction and wear on the wheel structure, forming initial defects and inducing fatigue cracks. Furthermore, this structure is simpler than combined heat shield assemblies, requires fewer parts, and has a lower material density.

The clamps and other connecting structures are welded, eliminating the need for separate structural components compared to the various fixing structures in combined heat shield assemblies, such as fixing rings and rivets. This results in lighter weight, simpler structure, and smaller required structural space.
