Approximate Thermal Analysis of Heating and Deformation of a C/C-SiC Plate in a Scramjet Engine

Abstract

The paper provides a brief overview of heat-resistant materials used by the United States, Germany and Australia the creation of high-speed aircraft. A simplified mathematical model of heating and deformation processes in a C/C-SiC plate based on thermoelasticity equations is formulated. The problem statement is as follows: for a composite plate located on the scramjet engine housing, under given thermal effects and properties of the construction materials, the fields of temperatures, displacements, components of stress and strain tensors are determined. The heating and deformation values in the C/C-SiC plate are estimated.
