Evaluation of stress-strain state of thermal protection coating of pipe channel loaded with high-temperature power pulse

The article is devoted to an approximate assessment of the stress-strain state of the thermal protective coating of the pipe of the gas-dynamic impulse device under the influence of a short-term high-temperature pulse of high pressure. The results given in the article show that the thermal protective coating experiences alternating loads during a single pulse, the magnitude of which depends on many factors, which determine both the characteristics of the pulse itself and the thickness of the pipe and the properties of the coating itself.
