February 17, 2012 | McNally Industries has been awarded an engineering contract to improve the Life Cycle of one of the bolts in a gun used by the Air Force. The current average time to failure is approximately 75,000 rounds and the Air Force is seeking to extend the Life Cycle to 150,000-250,000 rounds. The SOW includes failure analysis, FEA, assessment of material options and finishes, and manufacturing test assets to prove functionality and performance of the new design in live fire testing. McNally was selected for this task because of our long history of engineering and manufacturing internal gun components.
