Standardization of AIRCRAFT - ENGINE COMPONENTS 410118
STANDARDIZATION of engine components should start in the drafting room with use of a system of sample drawings, Mr. Corvelli contends, and dimensioning of parts should be simplified through use of a two-place decimal system.
He emphasizes the importance of standardization of notes, clearances, tolerances, and other data listed on drawings. In addition, threaded parts, gear tooth form, and many such items can and should be standardized, and serious consideration should be given to adoption of the metric system.
Since the Army-Navy (AN) Standards were developed primarily for airplanes and often do not apply to aircraft engines, he points out that a new set of standards must be developed for parts used on engines only.
