FIELD: heating.
SUBSTANCE: impact action structure in an impact cooling system has holes for impact action, which are made so that passage of a flow of a cooling agent and direction of the obtained jets of the cooling agent is performed to a target surface located opposite the above structure through a cavity formed between them. The above structure has a corrugated configuration and is located at a distance from the target surface. The target surface includes a flame tube outer surface. The structure includes a connection pipe for a flow in a combustion chamber of a gas-turbine engine or the target surface includes the outer surface of a transient compartment. The above structure includes a connection pipe for impact action in the combustion chamber of the gas-turbine engine.
EFFECT: invention is aimed at improvement of cooling.
