STATOR BLADE HAVING LOCALLY REWORKED SHAPE, STATOR SECTION WITH SUCH STATOR BLADE, COMPRESSION STAGE, COMPRESSOR, AND TURBOMACHINE

摘要

PROBLEM TO BE SOLVED: To newly rework a geometrical shape of a stator blade so as to locally reduce a stress level.

SOLUTION: A new type of a stator section to be locally reworked for the geometrical shape of the stator blade is provided. The stress level of a brazed section for joining the stator blade with an outer shroud can be reduced on the basis of this reworking without necessitating further aerodynamic technology. The thickness of the stator blade is continuously increased in order to reduce the stress level, and further, a radius of a rear edge of the stator blade is continuously and locally increased.
