NUMERICAL SIMULATION OF A THERMAL-PROTECTION ELEMENT OF A PROMISING REUSABLE CAPSULE-TYPE LANDER

An indestructible multilayer thermal-barrier coating is proposed for a promising reusable capsule-type lander. This coating is based on a porous carbon-ceramic material. The thermal state of the coating proposed was simulated mathematically for different types of its reinforcement and different values of the porosity and the heat-conductivity coeffi cient of the carbon-ceramic material. Results of a numerical simulation of the temperature state of an element of the multilayer thermal-barrier coating are presented. On the basis of these data, the thickness and the weight effi ciency of the coating were estimated.
