Concerning the further development of gas turbine engines, advances of the aero-thermodynamic design can be achieved most efficiently by cooperative efforts aimed at the improvement of both the numerical simulation methods and the experimental test and measurement techniques. Rapid development of numerical capability is accompanied by increasing demands on experimental data. In this context sig...

Designs for future aero engines aim increased efficiency with reduced exhaust gas and noise emissions. To achieve these goals, comprehensive physical understanding highly innovative solutions are necessary. Even though computational capabilities rising, the required confidence level is restrained. understand validate theoretical numerical models, extensive experiments at realistic operating con...

Abstract This paper presents high-speed two wavelength interferometry for measuring fast phenomena, which allows to extend the dynamic range of measurement using different wavelengths at same time. The method was applied measure transonic airflow through a blade cascade
