| Abstract [eng] |
One of the most important components of aero engine is the turbine blade. The additive manufacturing (AM) of jet engine turbine blade is complex as the machining process involves majority of the challenging aspects of metal cutting. Due to the reason of complex component geometry, surface roughness and variable thickness it is very hard to perform the inspection on such components. Even with the probability of having several defects, various nondestructive testing (NDT) techniques may perhaps be needed to inspect the component to detect the defects. Using numerical modelling in CIVA software, the purpose of this analysis is to identify the artificial internal defects in the turbine blade using immersion nondestructive testing (NDT) technique. The flaw size and geometry can be determined from the images produced by the ultrasonic scan. |
