MANUFACTURING PROCESS FOR A TURBINE STATOR BLADE AND ITS PIVOT |
摘要 |
A method of manufacturing a variable incidence stator blade assembly comprising forming a blade with a root which forms an extension of the aerodynamic profile of the blade, forming a bush with a recess accommodating the root by ultrasonic, electro-chemical or electro-erosion machining and assembling the blade and bush in a turbo-machine outer casing and in an inner ring of channel section. A variable incidence stator blade assembled in a compressor of a gas turbine is also described, the blade assembly being as manufactured by the method. The channel section inner ring carried an abradable layer which co-operates to form a seal with annular lips carried by the compressor rotor drum. |
