GOM’s measurement systems provide strong gear rack support to the aerospace market and its suppliers by giving accurate part geometry and material properties. The relevant data was utilized for finite component simulation and flow analysis, and the real data attained in the wind tunnel and environmentally friendly test box were in comparison for simulation verification and input parameters for invert engineering. Optical 3D scanners are specially ideal for quality control of complicated free-form surfaces. Therefore, they are used to detect aircraft engine airfoils, property gas and steam turbines, and turbochargers.
