    Abstract

    The main objective of the present study is to subject NALPSP-02, an indigenously developed binary pressure sensitive paint, to supersonic flow conditions. An experimental study was carried out on a double-delta wing model at a free stream Mach number of 2.0 in the 0.3m trisonic wind tunnel at NAL. Pressure Sensitive Paint (PSP) technique was used to measure the pressure distribution on the lee side of the double delta wing at an incidences of 0°, 5°, 10° and 15°. The PSP results were compared against surface pressure data obtained using conventional pressure taps on the same model.
