Abstract
Pressure measurements by means of Pressure Sensitive Paint (PSP) technique,
requires extremely sophisticated image data processing. Beside standard digital
image processing routines, it is necessary to have specific algorithms to convert
input data in pressure fields mapped to a real model surface. An intensive effort
is underway at Italian Aerospace Research Centre (C.I.R.A.) to develop an
optical surface pressure measurement system for both transonic and subsonic
velocity fields. Actually, most of the activities are focused on the development of
original software for both paints' calibration and data analysis. This paper
describes the state of the art of PSP technique at CIRA, including data reduction
methods developed, as well as the optical pressure measurement arrangement
and the o
