ABSTRACT:Dayton T. Brown Inc. (DTB) and Fatigue Technology Inc. (FTI) propose the collaborative development of an all-platform standardized bushing system for AF Landing Gears (LGs). In order to minimize or eliminate the problems associated with traditional bushing installation methods, the use specially-engineered variant(s) of FTI?s ForceMate system is proposed. Accelerated simultaneous testing of current and proposed configurations will be performed in a specially designed chamber that makes possible the concurrent application of mechanical and environmental stresses. Using such advanced test concepts, optimized protocols (including CPCs, sealants, paints and finishes) for bushing installation will be developed based on a comprehensive set of quantitative test data, post-test failure analysis and an extensive suite of variants including the potential use of ultrasonics during installation.BENEFIT:The adaptations and refinements that will emerge from the successful completion of Phase I and then Phase II will further enhance the acceptance of this high interference bushing installation process, especially in the next generation of high strength landing gear materials which will make it a very attractive proposition. We will use the refinements gained to seek out applications in the current and next generation of commercial aircraft and high performance helicopters in landing gear as well as other diverse primary structural locations and use its established international market recognition to fully realize the commercial market place and capitalize on these latest refinements.
