Abstract

The paper considers various approaches to producing baroindicator coatings for the study of the pressure distribution in wind tunnels. It has been shown that for pressure measurement in hot-shot wind tunnels the coatings applied on the modified pyrene of porous material which have much less response time than polymer ones. It has been found that in this case using laser-induced fluorescence excited by an impulse UV-laser for pressure fields visualization, response times of about 30 ns can be obtained.
