This is a study of the relationship between aircraft readiness and spares usage at the squadron level, specifically for the F-4B, CH-53, and TA-4F. The study determines the best combination of aircraft, maintenance man-hours, and spare parts for various budgets. Since the availability of spare parts is a big factor in aircraft readiness, a detailed examination was made of the spare parts resupp...

Construction equipment is typically massive and operated manually with minimal use of sensors or computers for measurement or control. Research in the Intelligent Systems and Structures Divisions at the National Institute of Standards and Technology has explored innovative ways to use sensors, computers, and lightweight, tensioned, cable machines for heavy manufacturing and construction tasks s...

This paper investigates the precision and capability of low cost off-line industrial photogrammetry for determination of deformations in aircraft parts. The study concentrates on deformation analysis of an airplane propeller through standard photogrammetric procedures. In this regard, around 100 targets were fixed on the blades of the propeller and imaged from several stations. The left and rig...

The developers of magnesium metal production were always interested in methods of producing alloys and products. Casting was the first major development in the production of structural parts, but rolling, forging and extrusion closely followed it. This paper reviews the tremendous historical developments in wrought products during the 1930’s and 1940’s. At the peak of magnesium production for W...
