This paper describes measurement methodology and comparative results obtained using both the Pressure Sensitive Paint (PSP) and novel Surface Stress Sensitive Film (S3F) techniques. A wind tunnel test was performed by EADS together with ISSI to investigate PSP at low speeds in order to compare absolute PSP pressures and S3F relative pressure data on a typical high speed aircraft model. Furthermore the ability of the S3F film to sense wall shear stresses was demonstrated. Measurements were conducted in the flow range of 10-50 m/s, angles of attack of 10° and 30° and with two model configurations (with and without an air brake).
