Abstract

PURPOSE: To measure sound waves correctly and know a deteriorated degree of a material easily by a method wherein side end faces of a dynamic blade planting portion are made parallel to each other to make a distance between transmitting and receiving probes equal, in the outside dovetail type dynamic blade planting portion.
CONSTITUTION: In an outside dovetail type planting portion 6 planting dynamic blades in a circumferential direction of a rotor wheel, a distance between transmitting and receiving probes at each portion becomes equal by making side surfaces 4, 5 parallel to each other. Thus, the distance between both of the probes can be discriminated correctly, therefore, correct sound waves may be measured and deterioration of material at respective portions of the planting portion may be discriminated. For further reference, a spacer 8 is inserted into a space between a prior-art type planting portion 1 in which the side surfaces thereof are inclined.
