GOM’s measurement systems provide strong support to the aerospace industry and its suppliers by providing accurate component geometry and materials properties. The relevant data was utilized for finite component simulation and flow evaluation, and the real data obtained in the wind gear rack tunnel and environmentally friendly test box were in comparison for simulation verification and input parameters for reverse engineering. Optical 3D scanners are specially suitable for quality control of complex free-form surfaces. For that reason, they are used to identify aircraft engine airfoils, land gas and steam turbines, and turbochargers.
