Airfoil Inspection Method
US Patent:
4908782, Mar 13, 1990
Filed:
May 19, 1983
Appl. No.:
6/495961
Inventors:
Herbert C. Pekarek - Gates Mills OH

International Classification:

US Classification:
364560
Abstract:
An improved inspection method determines how closely the cross sectional configuration of an airfoil corresponds to a reference cross sectional configuration. When an airfoil is to be inspected, the airfoil is measured and the mean camber line is determined. The mean camber lines of the reference and measured airfoils are shifted relative to each other through a plurality of relationships. A best fit relationship is determined in which the measured and reference airfoils overlie each other to a maximum extent possible. The best fit relationship can be determined by comparing points on the major side surfaces of the measured and reference airfoils. Alternatively, the best fit relationship can be determined by comparing points on the mean camber lines of the measured and reference airfoils.
