Abstract
Purpose
Paper aims to present problem of aerodynamic heating of a metallic heat shield. The key elements of this construction are metallic layers of superalloy honeycomb, which significantly increase the structure’s resistance to impact. Paper describes the problem of influence of damage size on increase of thermal load.
Design/methodology/approach
Numerical analysis was performed in a non-commercial environment FreeFem++ using finite element method, and its results were compared with the results given in the literature.
Findings
In thermal protection system, a modification was used to delay increase in temperature on the underlying structure as well as to reduce its maximum value.
Originality/value
In the further part of the paper, selected insulation material was modified by adding additional conductive material.
