Advanced two stage single shaft centrifugal compressor for small engines

The results are usable for further development of small engines incorporating centrifugal compressors. Measured data and following analysis have been used for correcting of the design method (developed for centrifugal compressor stage and used at WALTER ENGINES a.s.) to obtain more accurate results, primarily for the impellers with higher angle of backswept vanes at the outlet. Significant experience with system of compressor mass flow control operating as a part of gas generator especially water injection in front of the combustion chamber has been gained during the test and it has brought in addition a new knowledge of small engines gas generator thermodynamical behaviour. Design of gas generator as a test device for compressor testing proved design possibilities and difficulties of similar arrangement especially from the dynamic behaviour of complicated rotor system point of view.
