Plant Layout and Production Methods for Modern Aircraft Engines 370145
THIS paper presents a brief history of the experience of Pratt & Whitney Aircraft, division of United Aircraft Corp., in building high-powered air-cooled radial aircraft engines.
Pictures and diagrams of the plant layout are analyzed in such a way as to show the unusual foresight employed in providing for the future. This arrangement has permitted quick expansion without disturbing production or without revising any of the important features of the original layouts.
Engines are not assembled for stock, and schedules are based on customer requirements with special treatment for Army, Navy and commercial engines. The important part played by inspection and quality control is outlined together with the method of fitting it into the production scheme and the method of meeting the special requirements of Army and Navy.
An appendix includes typical operation sheets illustrating in detail the method of manufacture used to meet the high-performance characteristics required in a master connecting-rod, as illustrating typical problems encountered in the production of an engine of this character.
