GKN Aerospace in collaboration with Northrop Grumman deposited a large scale titanium aerostructure representative of a primary air vehicle structure. The titanium laser wire directed energy deposition (DED) preform measures approximately 8 feet (2.5 meters) and is the largest additively manufactured aerostructure produced by GKN Aerospace to date. The demonstration article utilized novel toolpathing techniques to manage thermal history and distortion concurrently. In addition, the deposition was completed first-time-right using GKN’s proprietary adaptive closed loop control systems to maintain build quality throughout the deposition. This milestone demonstrates cutting-edge manufacturing technology to build large primary aerostructures for future air vehicles. This presentation will shares the whole story of adaptive closed loop control, toolpath, and thermal history management to deposit a preform of this monumental scale.
