METHOD OF MAKING STATOR STAGES FOR COMPRESSORS AND TURBINES,AND STATOR VANES AND VANE ARRAYS PRODUCED THEREBY

摘要

According to the invention, the grids of stator vanes on the basis of a bar b, linear machined in which the cutting of blanks of the blades 1 by wire electroerosion is then machined the convex surface 18 and the intrados by electroerosion or by chemical machining and is welded edge to edge the feet of the blades in order to form a sector of a grid or a complete grid. / p & & p & application in particular to the stators of turbomachine compressors, blades comprising a cross-sectional profile evolutive.
