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