AM of front bearing housing aerofoils for test bed engines


Development of additive layer manufacturing (ALM) has not only been limited to small and intricate components. Rolls-Royce have pioneered the development of larger significant parts and associated technologies for structural engine components. The front bearing housing is the largest aero engine structure to fly, incorporating ALM components, in the world to-date (Nov 2015).


Working in conjunction with Rolls-Royce and Arcam, MTC developed processes from powder inspection and characterisation through component manufacture to post process nondestructive testing of the ALM components
