Many of today’s inspection issues are due the geometric constraints, restricted access and anisotropic material properties. Near net shape manufacturing creates complex geometric components where in-service inspection can be very challenging. Good examples are single crystal turbine blades and additive manufactured parts. In-situ inspection of such components is constrained by access issues affecting the ability to detect defects. Ultrasonic inspection methods are required where direct line of sight to the defect does not exist. New ultrasonic imaging techniques have recently been developed with potential for inspecting such awkward geometry, such as multi-mode array imaging. However, there are several challenges that remain to transfer the ideas to real components. The project will include delivering an assessment of existing concepts to image defects where line of sight does not exist and coping with both anisotropic and isotropic material properties. The student will work at the University of Bristol before relocating to Rolls-Royce in Filton (Bristol) for a significant portion of their studies, with frequent trips to the University of Bristol. The student will work alongside engineers developing inspections and will have the opportunity to influence future inspection capability for aero-engine components. For more information, please visit
