Compressor of turbine blade manufacture.

摘要

A turbine or compressor blade holding fixture and machining method contemplates the subassembly of all the blades 20 upon the rotor 12 of the compressor or turbine. Fixture rings 30, 32 along with radial biasing members in the form of annular o-rings 40, 42, 44 are intersecured to opposite sides of the blades 20 so as to radially position the latter in their normal "running position" while so mounted on the rotor 12 of the wheel. In such condition all of the blades 20 may be simultaneously machined such that the outer tips 24 thereof lie on a true uniform, desired outer diameter to provide subsequently uniform tip clearance to the surrounding shroud when mounted in a gas turbine engine for operation.
