OPTIMIZED GUIDE BLADE, RING-SHAPED BODY SECTOR OF GUIDE BLADE, COMPRESSION STAGE HAVING THE SAME GUIDE BLADE, COMPRESSOR, AND TURBOMACHINE

摘要

PPROBLEM TO BE SOLVED: To provide a newly optimized aerodynamic contour of a guide blade. PSOLUTION: In a ring-shaped body sector of the new guide blade, a local structure between a shape and geometrical shape of the guide blade is optimized, and a stress level of a brazed joining section for connecting the guide blade with an outer shroud can be reduced. Further, the ring-shaped body sector of the guide blade can satisfies aerodynamic and mechanical requirements given to the guide blade. PCOPYRIGHT: (C)2008,JPO&INPIT
