Application and validation of the gaussian beam superposition technique to simulate the inspection of aero engine components

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.
