Research on Thermal Protection Performances of Metallic Honeycomb Panel Subjected to High-Speed Thermal Shock

Abstract

In this paper, by using a self-developed transient aerodynamic thermal simulation system, the thermal protection performances of metallic honeycomb panel were tested at different transient heating rates, with a maximum instantaneous temperature reaching 950°C. Furthermore, a three-dimensional finite element model was established to determine the thermal protection performances of the metallic honeycomb panel in different simulation environments with high heating rates. The fact that the numerical calculations agreed well with the experimental results is a good foundation for replacing certain expensive thermal experiments with numerical calculations. The results of this research provided important reference values for the design of the thermal protection system comprising metallic honeycomb panel structures.
