Abstract: The dynamic characteristics and temperature effects of fast-response pressure-sensitive paint are the key factors for determining whether it is applicable to unsteady flow fields. This paper proposes a method for dynamic calibration of fast-response PSP (Pressure-Sensitive Paint), establishes a controllable calibration standing wave field through a dynamic calibration system that can adjust the temperature and frequency, and researches on the influence of temperature on pressure sensitivity and frequency response characteristics of the developed PC-PSP (Polymer Ceramic Pressure-Sensitive Paint). Dynamic calibration reflects the PSP characteris-tics more accurately than static calibration. Frequency changes have a significant effect on the pressure sensitivity of PC-PSP, and the influence of temperature on the pressure sensitivity of PC-PSP is not significant, while the temperature sensitivity of PC-PSP cannot be ignored in measure-ment. At the same temperature, the gain decreases and the phase lags behind as the frequency increases. At different temperatures, with the increase of the temperature, the cut-off frequency increases, and the phase lag gradually weakens. The dynamic pressure sensitivity at 20 ℃ and 0.5 kHz is 0.59%/kPa, and at 20 ℃ and 3 kHz is 0.51%/kPa, with the cut-off frequency being 4.8 kHz. Therefore, the performance of the tested PC-PSP is stable and meets the engineering requirements for unsteady flow field pressure measurement tests in low-speed wind tunnels.
