In this paper, an optical pressure measurement system based on the pressure-sensitive paint (PSP) technique was used for visualization and measurements of aerodynamic effects on a 3D aircraft model.Abstract:
The visualization and measurements of aerodynamic effects on a 3D aircraft model were conducted using an optical pressure measurement system, based on the pressure-sensitive paint (PSP) technique. PSP technology provides a good understanding of the flow around the wind tunnel model. The PSP technique can be used to carry out absolute pressure measurements on a surface of the model and to determine additional aerodynamic data using scientific-grade cameras and image processing techniques. Surface pressures from the top, bottom, left, and right viewing directions were obtained using the DLR-PSP system on the entire surface, which can be observed by eight CCD cameras. Finally, the measured pressures can be integrated to calculate the forces and moments of the complete model, or parts thereof.read more

TL;DR: In this paper, the authors demonstrated the feasibility of using the oxygen dependence of luminescent molecules for surface pressure measurement in aerodynamic testing, based on the observation that the light emitted increases as the oxygen partial pressure, and thus the air pressure, the molecules see decreases.
