GOM’s measurement systems gear rack provide strong support to the aerospace market and its suppliers by providing accurate component geometry and materials properties. The relevant data was utilized for finite element simulation and flow analysis, and the actual data attained in the wind tunnel and the environmental test box were compared for simulation verification and input parameters for reverse engineering. Optical 3D scanners are specially ideal for quality control of complex free-form surfaces. Therefore, they are used to identify aircraft engine airfoils, property gas and steam turbines, and turbochargers.
