Development and Experimental Investigation of PSP Technique for Pressure Field Measurements on Helicopter Blade.
Abstract
The report describes the main problems encountered during investigations of the oscillating pressure fields by the Fast Binary Pressure Sensitive Paint (FBPSP). This formulation has response time in the millisecond range and provides compensation of the model displacements and excitation light instability. Measurement methodology, theoretical and experimental estimations of the FBPSP dynamic characteristics are presented. It is shown that FBPSP formulation can be used for oscillation frequencies up to 20-40Hz but requires dynamic compensation of the resulting pressure fields. The experimental results obtained on the pitching wing model at Mach numbers 0.3, 0.4 and oscillation frequencies 0, 5, 10 and 20Hz are presented and discussed.
