Abstract

PURPOSE: To enhance the safety against the flutter (self-sustained oscillation) of a blade train including two or more moving blades, by making nonuniform the conditions of connection between each moving blade and a connector which couples the adjacent blades to each other and by also making the structure of the moving blade nonuniform.
CONSTITUTION: A connector 3 is provided through the central parts of moving blades 1, 4 to couple the plural moving blades 1, 4 to each other. A round bar is used as the connector 3. The bar is loosely fitted through holes 7, 6 perforated through the moving blades 1, 4. The bar is protruded from both the sides 10 of the moving blade 4 perpendicularly to the longitudinal direction of the blades or slightly obliquely to the longitudinal direction. According to this constitution, the conditions of coupling of the moving blades 1, 4, with the connector 3 and the structure of the blades 1, 4 are made nonuniform as the two or more moving blades 1, 4 are arranged. This results in enhancing the safety against the flutter of the blade train.
