The paper is concerned with flow past compressor blade cascade (NACA 65 with thickened trailing edge) at off-design regimes, which are characteristic by flow separation on the suction surface of the blades. The flow field was visualized using schlieren and surface paint techniques. The visualizations were complemented by measurement of the static pressure distribution on the suction surface of the blades. The results agree with the available literature showing that it is highly difficult to considerably control the complex 3-dimensional flow separation in the compressor cascade by control jets issuing (only) from the sidewalls.
