The paper presents a description of the comprehensive computational analysis aimed at providing compressor stable operation range. In this article author presents the computational predictions of compressor surge margin value, derived by means of originally elaborated analytical and numerical method. One has defined, in both analytical and numerical way, the influence of change of throat area of gasifier turbine nozzle guide vanes, and change of throat area of power turbine nozzle guide vanes on engine compressor surge margin measured in manufacturing conditions. The results of computational analysis are compared with measured parameters obtained from experimental tests of turbohalt engine. Conclusions from the computational analyses are then presented.

Praca obejmuje opis wszechstronnej analizy teoretycznej prowadzonej w celu zapewnienia zakresu statecznej pracy sprężarki. W artykule przedstawiono obliczenia wartości zapasu statecznej pracy sprężarki, wykonane przy użyciu opracowanych przez autora oryginalnych metod analitycznej i numerycznaj. Metodą anlityczną i numeryczną określono wpływ zmian przekroju minimalnego wieńca dyszowego turbiny wytwornicowej i turbiny napędowej na zapas statecznej pracy sprężarki mierzony w warunkach produkcyjnych. Rezultaty badań teoretycznych zweryfikowano parametrami zmierzonymi, uzyskanymi podczas badań eksperymentalnych silnika śmigłowego z wolną turbiną napędową. W zakończeniu pracy przedstawiono wnioski wynikające z porównania wyników badań teoretycznych i eksperymentalnych.
