Paper Abstract

In the development of new airplane generations at DaimlerChrysler Aerospace extensive testing of new designs and geometries is performed in the wind tunnel. Models to various scales are built from steel and aluminum by milling. To achieve optimum performance in the airstream, the model surface is hand-finished according to the CAD design geometry. In the past this finishing process was controlled in several measurement loops with a tactile coordinate measurement machine. This was very time consuming and could only be performed at discrete points of the model surface. The optical measurement and inspection system WinGS (Wing Geometry Sensor) was developed to significantly increase the speed of the shape control process and to measure the complete 3D-surface of the model. The system consists of a fringe projection sensor with photogrammetric orientation. The 3D-geometry of the model surface is digitized and the deviation from the designed CAD model is calculated and displayed as a 2D false color map. The complete measurement, analysis and display cycle time is 25 seconds. The accuracy of the system is plus or minus 0.03 mm on whitened surfaces up to 400 X 280 mm2. The overall measurement volume is 1.5 X 1 X 0.5 m3.
