<p><P>PROBLEM TO BE SOLVED: To provide a method for replacing a rotor blade without disassembling a rotor in the rotor with the rotor blade that may be deteriorated by the lapse time. <P>SOLUTION: First and second rotor portions 28, 30 of the rotor 20 of a turbomachine have first and second rims 38, 40 which are spaced with a predetermined distance apart from each other and have peripheral slots therebetween. The first and second rims have first and second dovetail slots extending therethrough communicating with a peripheral slot 42. First and second blades 48, 50 have first and second dovetails. The first dovetail is disposed in one of the first and second dovetail slots, and the second dovetail is disposed in the other of the first and second dovetail slots. The peripheral slot 42 has a sufficient size to make first and second blades 32, 34 pass therethrough when the first and second blades 32, 34 are removed from the rotor 20. <P>COPYRIGHT: (C)2009,JPO&INPIT</p> |
