Within the European research project VERDICT, the Gaussian beam superposition technique has been specifically refined to meet the simulation needs of aero engine manufacturers. Testing and validation of the refined method have been performed. A variety of simulation results, covering beam fields in water as well as C-scans obtained on flat bottom holes in curved test specimens are shown in comparison with experimental data; excellent agreement has been obtained. Testing and validation of the Gaussian beam superposition method adapted to curved components have been performed using experimental data provided by MTU. The experimental set-up is a standard one, routinely performed on aero engine components. Excellent agreement between simulated and experimental results has observed. The experimental tendencies are generally well simulated. In principle, quantitative results show a difference between simulation and experiment of less than to 2 dB. Also, important features of the beam fields and the C-scan patterns are successfully predicted by the Gaussian beam superposition.
