Manufacturing developments to reduce strategic materials usage
Abstract
Manufacturing development programs to reduce the usage in gas turbine engines are examined. Several programs which provided significant of cobalt, titanium, and tantalum results in reducing raw materials requirements, that have been reduced to practice are described. The programs include forging and casting complex parts to near net shape, recycling of machining scrap and used parts, repair and refurbishment of damaged or worn parts, and component retirement for cause. In addition to reduction of strategic material usage, the programs resulted in lower cost parts due to reduced material input requirements and less machining.
