The pressure‐sensitive paint (PSP) has potential as a diagnostic tool for pressure measurement in the high Knudsen number regime because it works as a so‐called “molecular sensor.” However, there are few reports concerning application of the PSP to micro devices, because the conventional PSP is too thick owing to the use of polymer :// This paper describes the results from a proof of concept test to examine the feasibility of using pressure sensitive paint (PSP) to measure global surface pressures on rotorcraft blades in hover.
