Inspection of a Portion of a Propeller Leading Edge by Obtaining a Cast Plastic Duplicate.

Abstract

A method for the inspection of full scale propeller leading edges that are not mathematically defined or that have been modified in the field is required to aid in defining the numerical coordinates of the leading edge contour. A method of obtaining an impression of a portion of a propeller leading edge is described herein. The method fixes a number of reference dimensions relative to the propeller. Subsequent plastic castings taken from the impression may be inspected with the aid of these dimensional references. The unknown portion of the leading edge contour may then be defined and added to the numerical specification of the propeller. (Author)
