Abstract

As part of the Brite/EuRam programme "Aeromechanical Design of Turbine Blades" (ADTurB) experiments in a stator with 43 nozzle guide vanes have been carried out in the windtunnel for rotating cascades (RGG) at DLR Goettingen. Hub and tip boundary layers have been measured in the stator inlet flow field. Blade surface pressure distributions were measured at 20%, 50% and 90% blade height, and wake traverse measurements (total pressure and flow angle) have been carried out at 3 axial positions and 20%, 50% and 90% flow channel height. All investigations were done with a subsonic (0.85) and a supersonic (1.05) isentropic exit Mach number.
