ROTATING BLADE WITH SHROUDING WING Russian patent published in 1996 - IPC

Abstract RU 2064593 C1

FIELD: turbine manufacture; turbomachine runners. SUBSTANCE: developed cylindrical surface of shrouding wing has convex and concave sections on opposite ends designed for interaction with respective concave and convex sections of shrouding wings of adjacent blades. At least one of end surfaces of these sections is convex with curvature radius at least ten times greater than thickness of shrouding wing at end thus ensuring complete engagement and lapping of contact surfaces of shrouding wings of adjacent blades. EFFECT: improved design. 1 cl, 2 dwg
