US Patent:

51917114, Mar 9, 1993

Filed:

Dec 23, 1991

Appl. No.:

7/812776

Inventors:

Thomas E. Vickers - Mesa AZ
James A. Sanger - Prescott AZ

Assignee:

Allied-Signal Inc. - Morris Township, Morris County NJ

International Classification:

B23B 100

US Classification:

2988921

Abstract:

A turbine or compressor blade holding fixture and machining method contemplates the subassembly of all the blades upon the rotor of the compressor or turbine. Fixture rings along with radial biasing members in the form of annular o-rings are intersecured to opposite sides of the blades so as to radially position the latter in their normal "running position" while so mounted on the rotor of the wheel. In such condition all of the blades may be simultaneously machined such that the outer tips 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.
