Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a method and a cooling system for cooling blades in at least one blade row in a rotary flow machine, which simplifies feeding of cooling air into the rotating blades of the rotary flow machine.SOLUTION: Pressurized cooling air 8 is fed through from radially outside toward the tip of each blade 1 in at least one blade row, and the pressurized cooling air 8 enters the blades 1 through at least one opening 9 at the shrouded blades' tip.
