AXIAL COMPRESSOR

摘要

PROBLEM TO BE SOLVED: To restrain a stall from occurring and restrain surging phenomenon by reducing a chip clearance flow flowing from a positive pressure surface to a negative pressure surface of a moving blade even when the blade is in a high load state. SOLUTION: A moving blade cascade 10 is provided which decelerates an axial speed and has an outlet sectional area larger than an inlet sectional area so as to reduce a pressure difference between the positive pressure surface and the negative pressure surface. A stationary blade cascade 11 is arranged to a downstream side of the moving blade cascade 10. An outlet sectional area of the stationary blade cascade 11 is smaller than the inlet sectional area of the moving blade cascade 10. COPYRIGHT: (C)2004,JPO
