Superplastic Formed and Diffusion Bonded Titanium Landing Gear Component Feasibility Study.

Abstract

This report describes the development, fabrication and testing of a section of a main landing gear outer cylinder. The program demonstrated the feasibility of using the SuperPlastic Forming with concurrent Diffusion Bonding (SPF/DB) fabrication process to build a titanium cylindrical sandwich structure with a weight savings of 8-1/2 percent over the baseline steel cylinder. The development of joints, stop-off application and tooling is described. Structural analysis and subsequent structural testing proved that the cylindrical sandwich design is capable of meeting the loads that the outer cylinder of the landing gear would be subjected to in a current first line fighter aircraft.
