SST Technology Follow-on Program-Phase 2. Development and Evaluation of the Aluminum-Brazed Titanium System. Volume 1. Program Summary
Abstract
Development and evaluation of aluminum-brazed titanium on the SST program was limited to specific applications and requirements of the prototype airplane. Subsequent to cancellation of the SST, the Department of Transportation (DOT) sponsored a two-phase technology follow-on program for aluminum-brazed titanium. Phase I documented the development status at termination of SST activities and authorized limited test work. Phase II authorized continued development of the braze system to optimize braze alloys, brazing processes, system scale-up, environmental testing, producibility, and structural verification. This report summarizes results of Phase II work. Marked advancements were achieved in design and manufacturing criteria for aluminum- brazed titanium structure. System capabilities were successfully demonstrated by fabrication, test, and analysis of brazed hardware encompassing a wide range of configurations, structural load capacities, and test conditions. Results substantiate that aluminum-brazed titanium honeycomb sandwich structure is well suited for aircraft applications. This braze system has been selected for use on the F-14, F-15, and B-1 airplanes. Control surface assemblies have been fabricated and certified for service evaluation on commercial subsonic aircraft. Areas of further development for increased system applications are defined.
