BLADE, PARTICULARLY, TURBOMACHINE BLADE

摘要

FIELD: machine building.SUBSTANCE: blade component comprises inner space between two opposite component inner walls. The latter make the coolant passage directed toward fluid outlet in the component trailing edge. There are multiple ribs extending from two opposite inner walls to make multiple channels on both opposite inner walls to direct coolant toward trailing edge. Said ribs on opposite sides are inclined relative to each pother to make a matrix-type configuration. Inner space is divided into front section in direction toward the component leading edge and rear section in direction of the component trailing edge. The ribs are located in said front section. Besides, claimed component comprises multiple tenons extending from two opposite inner walls located discretely in rear section. Additionally, this component comprises mid section arranged between front and rear sections. The mid section contains ribs and thorns.EFFECT: higher cooling efficiency.13 cl, 5 dwg
