FLOW PATH FOR COMPRESSOR WITH FLUTE

摘要

PROBLEM TO BE SOLVED: To enhance the performance of a gas turbine engine compressor and a fan in spite of geometrical restriction. SOLUTION: A compressor flow path 20 contains a blade-shaped part 16 having a leading edge 28 and a trailing edge 30 positioning at a certain interval in the axial direction and an outer end 32 and an inner end 34 positioning at a certain interval in the radial direction, and positioning at a certain interval in the circumferential direction. An outside wall 36 is bridged to the outer end of the blade-shaped part, and an inside wall 38 is bridged to its inner end. One of walls contains a a flute adjacent to the leading edge in order to locally increase the flow area.
