ABSTRACT:
A gauge for measuring the chord length across an airfoil at a plurality of locations along the span is disclosed. Concepts ensuring accurate measurement notwithstanding deviations of the airfoil contour from design conditions are discussed. Floating gauge plates 46 locate the local position of the airfoil leading edge. A notch 58 in each plate marks the minimum acceptable chord length.
