Abstract

FIELD: gas turbines. SUBSTANCE: moving blade has feather with upper cavity and front and rear cavities separated by longitudinal partitions; side walls of the latter have parallel ribs inclined to feather axis on back and trough sides in opposite directions contacting through their ends at intersection points and forming interrib channels communicating with upper cavity; novelty is that part of interrib channels of front cavity near longitudinal partition communicates directly with rear cavity. EFFECT: improved economic efficiency of cooling.
