Abstract

FIELD: gas turbines of aviation engines. SUBSTANCE: rib 4 is discontinuous and its height is determined from inequality 0,3d< h < 0,5dwhere dis hydraulic diameter of passage. Cooling air is swirled by ribs 4 forming vortex motion of coolant in passage at optimal height of rib 4. EFFECT: enhanced efficiency of blade cooling. 2 dwg
