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