Techniques, Processes, And Tools For Implementing An Integrated Corrosion Detection System

Under SBIR Program Solicitation FY07.1, Navy Topic N07-038 entitled, "Techniques, Processes and Tools for Implementing an Integrated Corrosion Detection System”, the NAVY has identified a need for the development of techniques, processes and tools for corrosion detection in large military aircraft. The technical problem being addressed in Navy Topic N07-038 arises from the limitations of the current methods of detecting corrosion in large military aircraft by manual inspection of aircraft surfaces by maintainers in the field and at the depot level. Furthermore, these schedule-based detection methods are time consuming and quality of inspection is limited to detection by the human eye. Also, inspection in non line-of sight and tight spaces is not possible without a borescope or other item of non-destructive inspection equipment. To solve these problems, the Navy is seeking methods to identify early signs of corrosion and alert maintainers for detailed inspection based on physics of failure. In response to this need, Laser and Plasma Technologies, Inc. (LPT) proposes the use of optical methods such as color change under strain created due to corrosion process, optical scanning method and optical shearography to develop an efficient, compact system for corrosion detection as well as the application of physics of failure to this problem. The Investigators anticipate success in both the development of early detection system using novel optical methods and its relationship to structural integrity based on the unique symbiosis in capabilities found in the collaboration between LPT and the Subcontractor to the program, the University of Virginia.
