The wake behind a simpli¯ed model of a generic aircraft (the SWIM model) is measured in the Low Speed Low turbulence wind tunnel (LSL) at Delft University of Technology. Two measurement techniques have been used in order to qualitatively and quantitatively measure the wake, i.e. stereoscopic particle image velocimetry (Stereo PIV) and a 5 hole probe (5HP). Furthermore balance measurements have been carried out over a range of con¯gurations for later comparison purposes. The goal of the wake measurements is to give a comparison between the two measurement techniques. The 5HP measurements are processed using a windows based program called Pressure Field Visualisation. This program calculates vector ¯elds from the input pressure data and has several exporting options. The Stereo PIV measurements are correlated using DaVis 7.3 using a window size of 16 x 16 pixels with 50% overlap.
