Keywords: thermal protection, ablative material, lithium hydride, thermochemical decomposition, flattened pipe, heat transfer by radiation and convection

The investigation concerns efficient thermal protection methods for structural elements of promising aircraft engines, such as combustion chambers, flow ducts, combustion chamber and afterburner shells of ramjet engines. We implemented forced convection cooling of the structural elements subjected to the highest thermal stresses, which makes use of the cooling capacity of the engine fuel components. However, in some cases this is not enough; as a result, we must consider alternative thermal protection, for example, ablative coatings
