It is inevitable that components come to an end of life. This week in Gensrv we completed a very critical replacement of some turbine compressor blades. These GT blades are the first set found in the GT compressor and as such are also the largest. The blades are fitted with mid span connections to reduce vibration. Where each blades midspan spur meets there is a ware pad damper. The blades in this machine had lost all material from the ware pads increasing blade flex and vibration. All blades were removed and new balanced items fitted.
