About this file
This document is a detailed technical drawing for a 29 B Stator, a machined mechanical component designed for high-vibration environments. The part is specified to be manufactured from a solid 316 Stainless Steel billet with precise dimensional tolerances and specific manufacturing requirements. Key technical specifications include:
Dimensional details: The stator has a circular design with multiple blade-like features, measuring approximately 5.400 inches in diameter with complex geometric tolerances. Critical manufacturing notes mandate that placement faces must be machined perpendicular to each other (90±0.1 degrees), blade root and shroud fillets must be 0.050", and blade surface finish must meet 63 CLA standards. The drawing includes front and rear views, section views, and detailed annotations for precise manufacturing, including 8 equispaced drill holes, 4 tapped #10-32 UNF jacking screw holes, and specific dimensional tolerances ranging from ±0.002 to ±0.001 inches. The document is marked as proprietary to the Naval Postgraduate School and dated 10-9-20.
