FIELD: supersonic ramjet engines.
SUBSTANCE: proposed ramjet engine has upper bounding wall, lower bounding wall and side walls forming inner passage for gas flow and cooling passages. All walls are formed by group of hollow heat-exchange panels and each panel has group of interconnected structural panels and facing sheet. Cooling passages are made in structural panels. Facing sheet is connected with each structural panel by platforms between cooling passages of respective structural panel. Heat-exchange panel is provided with cooling passages and group of structural panels forming hollow structure and facing sheet. Cooling passages are subjected to machining.
EFFECT: low cost; low flight weight of engine.
