South Dakota School of Mines & Technology and Ellsworth Air Force Base have signed a formal partnership to jointly undertake project research aimed at modernizing aging bombers. To date, four B-1 bombers have been refurbished, enabling them to remain in service and saving the military millions of dollars.
Using a process developed in collaboration with the Army Research Laboratory and currently under patent application, researchers employ cold-spray technology to deposit aluminum powder onto worn and damaged areas of aircraft skin panels. They then use machining to restore these areas to their original dimensions, enabling the bomber to return fully operational. Since OEMs no longer manufacture the aircraft components that were produced 30 years ago, the cost and time required to produce new skin panels are enormous, making it virtually impossible to replace them.
With approval, this year alone, the B-1 bombers at Ellsworth Air Force Base are expected to save $2.5 million in costs. Cold-spray technology can deposit a wide variety of metal powders onto surfaces of various materials, forming high-performance coatings without overheating the substrate. This technology can be used for similar repairs on other weapon systems and also has broad commercial applications.
