Cast Aluminum Structures Technology,Phase III (Cast).

摘要

The objective of CAST is to establish the necessary structural and manufacturing technologies and to demonstrate the validate the integrity, producibility, and viability of cast aluminum primary airframe structures. The baseline design is the AMST prototype YC-14 and the component selected was the Nose Landing Gear Support Bulkhead. Detail design activities are described that were aimed at providing a cast bulkhead design for production with no weight penalty and at a minimum of 30% acquisition cost savings. A detail design was completed that resulted in a 6.5-pound weight savings and an estimated 37.7% cost saving. (Author)
