SEATING SPRING OF VANE SECTOR AND HOLDING METHOD THEREFOR

摘要

PROBLEM TO BE SOLVED: To provide a vane sector seating spring for eliminating the possibility of no contact with an outer wall. SOLUTION: This seating spring 50 is provided for a gas turbine engine compressor stator 10 having a casing 12 having a circumferential directional casing slot 24 for installing plural vane sectors 20 on the outer wall 26. The seating spring 50 has at least one reaction tab 52 constituted so as to contact with the casing 12 on one side of the casing slot 24 and a spring arm 58 joined to the reaction tab 52 and constituted so as to press the outer wall 26 to the casing 12 on the second side of the casing slot 24 by contacting with respective ones of the outer wall 26. A holding arm 62 is joined to the reaction tab 52 to engage with the casing 12 to check so as not to move outward in the radial direction. Thus, the spring arm 58 is held in a state of contacting with the outer wall 26.
