In order to provide detailed experimental data to improve the state-of-the-art design tools for turbomachinery, a three stage high speed axial compressor with CDA is investigated covering its operation range up to full-load conditions. The results of the steady flow measurements characterise the overall performance of the machine and the behaviour of the blading under off-design conditions. The results emphasise the remarkable dependence of secondary flow phenomena as the wake durability and the region affected by the tip clearance vortex on different load conditions. Furthermore a close correlation between the blade loading of the last stator and the overall compressor performance can be detected.
