“…Considering that Therefore, similar to the light intensity method, the lifetime method also needs to collect the reference signal in the reference state and perform normalization processing. The PSP measurement technology based on the life method has been successfully applied to various rotating blade tests [9][10][11] , including helicopter…”

“…The method was previously applied by Disotell et al (2014) and Watkins et al (2016). It ignores adiabatic wall temperature variations along the chord, which depend on the local velocity distribution and therefore on the local pressure distribution (Jiao et al 2020). However, the pressure distribution in this study is not known apriori.…”

The study presents an optimized pressure-sensitive paint (PSP) measurement system that was applied to investigate unsteady surface pressures on recently developed double-swept rotor blades in the rotor test facility at the German Aerospace Center (DLR) in Göttingen. The measurement system featured an improved version of a double-shutter camera that was designed to reduce image blur in PSP measurements on fast rotating blades. It also comprised DLR’s PSP sensor, developed to capture transient flow phenomena (iPSP). Unsteady surface pressures were acquired across the outer 65% of the rotor blade with iPSP and at several radial blade sections by fast-response pressure transducers at blade-tip Mach and Reynolds numbers of $$\mathrm {M}_\mathrm{tip} = 0.282-0.285$$ M tip = 0.282 - 0.285 and $$\mathrm {Re}_\mathrm{tip}= 5.84-5.95 \times 10^5$$ Re tip = 5.84 - 5.95 × 10 5 . The unique experimental setup allowed for scanning surface pressures across the entire pitch cycle at a phase resolution of $${0.225}\,{\mathrm{deg}}$$ 0.225 deg azimuth for different collective and cyclic-pitch settings. Experimental results of both investigated cyclic-pitch settings are compared in detail to a delayed detached eddy simulation using the flow solver FLOWer and to flow visualizations from unsteady Reynolds-averaged Navier–Stokes (URANS) computations with DLR’s TAU code. The findings reveal a detailed and yet unseen insight into the pressure footprint of double-swept rotor blades undergoing dynamic stall and allow for deducing “stall maps”, where confined areas of stalled flow on the blade are identifiable as a function of the pitch phase.

“…Recent interest in luminophores utilization was found in other applications, such as its usage as PSP. Examples are the studies carried out by Jiao, et al [64,66,67]. In Jiao, et al [64] study, a twodimensional correction factor was adopted in the data analysis, so as to resolve the temperature sensitivity of the PSP.…”

Point MeasurementsA conventional point measurement technique is the thermocouple, which operates on the basis of Seebeck effect. In principle, two dissimilar metals are connected at a junction, which generates a small voltage with respect to a given temperature. Such technique was used to acquire average heat flux measurement over a surface of interest [6]. In parallel to this technique, Truong [7] considered using a heat fluxmeter, so as to evaluate the heat
