Abstract:

Results of a study program to evaluate the application of advanced titanium fabrication techniques to the Air Force B-1 bomber engine nacelle structure for improvements in cost and weight are presented. There are five items for the study. Two of them are primary structure, one of which is a removable access panel. The remaining three items are secondary structure. Superplastic forming with concurrent diffusion bonding, including expanded sandwich, were investigated. Weight savings range up to 49 percent. Potential weight savings are 362 pounds per aircraft. Cost savings range up to 69 percent, resulting in a potential savings of up to 48,622,800 for 240 aircraft. Author
