No. 15 - HPC Vane and Blade (5th- through 15th-Stage) Inspection
________________________________________________________________
(c) Examine the 5th- thru 7th-stage blades for curled leading edge tips (Fig. 611). 1) A curled blade has these conditions: a) A three sided corner of blade material with a bend line that goes from the leading edge to the tip b) The bend makes an angle of between 20 and 90 degrees from the usual concave blade contour. 2) The continue-in-service limits that are given are for all areas of the curled blade, but not for the bend line. a) No dents, holes, cracks, or scratches are permitted on the bend line.
3) Curled blades must have a minimum of three (3) straight blades between them, with no more than six (6) on each stage.
