Applications of the luminescent pressure sensor FOP-1 in high-speed wind tunnel

The Optical Pressure Measurement (OPM) technique is a kind of practical pressure measurement in high-sped wind tunnel. The pressure data on the wing surface of an airplane model by both OPM technique and clasic tap measurement technique in high-speed wind tunnel are given in this essay. The FOP-1 paint made in china was used in the OPM technique. The measuring results with the two techniques are discussed, and the performance of FOP-1 paint is proved to be good.
