The Visualization and measurements of aerodynamic effects on a three-dimensional aircraft model were conducted using an optical pressure measurement system, based on the Pressure Sensitive Paint (PSP) technique. The PSP technology provides a good understanding of the flow around the wind tunnel model. The PSP technique can be used to carry out absolute pressure measurements on a surface of the model and to determine additional aerodynamic data using scientific grade cameras and image processing techniques. Surface pressures from top, bottom, left and right viewing directions were obtained using the DLR-PSP system on the entire surface which can be observed by eight CCD-cameras. Finally, the measured pressures can be integrated to calculate forces and moments of the complete model or parts thereof.
