About this file
This is a technical engineering drawing for a sleeve component used in the Sting Model Support system at the Unitary Plan Wind Tunnel, produced by NASA's Ames Research Center in Moffett Field, California.
The drawing specifies a sleeve assembly (part number 327-1826-M54, Revision A.15) with an estimated weight of 215 pounds. The material is ASTM A668 Class M steel with minimum ultimate tensile strength of 125 KSI and Rc 25 minimum hardness, to be achieved through heat treatment after rough machining. The component features multiple press/shrink fit interfaces with four bearing race assemblies (A327-1826-M47-23 through M47-26) and includes detailed dimensional specifications with tolerances per ASME Y14.5-2009. Key specifications include outer diameters ranging from approximately 7.50 to 10.70 inches, various inner bore dimensions, and two slots in line with a removable reference dowel. All machined surfaces require sharp corner breaks with maximum 0.01-inch radius, and standard drilling hole tolerances apply. The drawing is marked as preliminary and dated April 23, 2024, indicating it is not approved for fabrication and further revisions are pending.
