Abstract�� Using the infrared radiation aerodynamic heating simulation test system, the heat-shielding properties of the metallic honeycomb panel were tested up to 800��; Taking into consideration of the radicalization among honeycomb wall surfaces and the heat transfer of metal structure and air within honeycomb core cavity, the finite element model was established in the numerical simulation to calculate the heat-shielding properties of the metallic honeycomb panels. The experimental results agree well with the numerical simulation results. The experimental and calculated results for heat-shielding properties of the metallic honeycomb panel up to 800�� provide an important basis for the safety design of high-speed aircrafts and vehicles.
Keywords�� honeycomb structure   heat transfer   experimental research   numerical simulation   finite element
