Praca opisuje niekonwencjonalną metodę podwyższenia sprawności turbin osiowych. Przedstawia wyniki badań eksperymentalnych i obliczeń numerycznych obejmujących interakcje poszczególnych wieńców turbiny, jak i zmiany geometrii ułopatkowania pierwszego stopnia. Wyniki wykazały zmiany sprawności na poziomie od 0.1 % do 0.5 %. Wykazały również, ze są one spowodowane parametrami wlotowymi stopnia i wzajemnym ustawieniem kierownic.

The paper describes an unconventional method of efficiency augmentation for the case of axial turbines. The measurement results are shown and next compared to numerical analysis. Rows interactions and geometry changes of the first stage are considered. The results showed the efficiency variations at the level of 0.1% up to 0.5%. They also proved that even with slightly changes of the inlet stage parameters and without great inference into the machine geometry improvement of the operational parameters can be achieved.
