Integrated surface pressure distribution measurements using thePSP technique on a three-dimensional aircraft model with a number ofvarious flaps, rudders and ailerons were performed at angles of attackbetween -4° to 36° , angles of sideslip between -13° to13° for Mach numbers from 0.6 to 0.95. In such cases, if thepressure distribution around the model is determined, forces and momentscan be calculated. In addition comparisons with conventional balancetechniques are possible. The main challenge to get good PSP results onone hand is the arrangement of hardware, components of modelillumination and camera observation - especially in the handling ofeight simultaneously operating CCD cameras. On the other hand thesoftware should be able to handle in a short time all the necessarysynchronization between the PSP-system and wind tunnel, all PSP images,correction of lens errors, model deformation etc.. This paper describeshow these problems are solved. A large number of results were mainlyobtained on the AerMacchi M346 trainer aircraft model in May 2000 in theDNW-HST at Amsterdam
