Inlet Flow Angle Determination of Transonic Compressor Cascades [PDF]
Journal of Turbomachinery, 1991 Tests of transonic compressor cascades require special measuring techniques to determine the inlet flow angle around sonic inlet flow conditions. One of the main requirements for these methods is the ability to adjust the inlet flow angle during the test to a prescribed value.

State-of-Art of Transonic Axial Compressors [PDF]
, 2011 Transonic axial flow compressors are today widely used in aircraft engines to obtain maximum pressure ratios per single-stage. High stage pressure ratios are important because they make it possible to reduce the engine weight and size and, therefore, investment and operational costs.
