The Department of Defense, specifically the United States Air Force, is seeking innovative solutions for in-place repair of structural components with stress-induced cracks in metal aircraft parts through its SBIR program. The objective is to develop and demonstrate portable ground support equipment capable of performing rapid repairs without removing components from the aircraft, thereby enhancing aircraft availability and reducing depot visits. This technology is crucial for extending the service life of aircraft parts, particularly aluminum alloys and steel, while maintaining their mechanical properties and dimensional tolerances. The solicitation is currently closed, with applications due by June 12, 2024, and further details can be found at the provided source link.
