Improvement of Fast Binary Pressure-Sensitive Paint Technology for Helicopter Rotor Blade Investigations
Abstract
The laboratory investigations of the characteristics of fast PSP are continued. In the first stage it was already investigated the spectra of emission and excitation, the calibration characteristics and the time response. In addition the spatial homogeneity of the covering is investigated. The scheme of experiment in T-105 wind tunnel using the helicopter devices MVP-5 and MVP-8 is developed and the supporting optical system is designed. The developed units and blocks to optical system are manufactured. The algorithms and programs of processing of the PSP images was enhanced to binary-type images. An units and techniques have been tested in TsAGI's T-125 wind tunnel at investigations of airfoil model with chord 100 mm, approximately equal to chord of model of the helicopter blade model under test.
