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 characteristics 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 measurement. 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.
