Abstract

The history of pressure sensitive paint (PSP) development and wind-tunnel applications is accompanied by efforts to exclude or minimize "non-pressure" differences between "wind-off\´ and "wind-on" conditions-in illumination levels, temperature fields, model displacements, and deformations. Time expenses for data processing were of second-order value. This paper describes technical solutions that can significantly reduce data-processing time to achieve near-real-time pressure field visualization. The key components are bi-luminophore PSP, a color CCD camera and time-optimized data processing
