Different amount of air in the fuel system wassimulated. The Euler method is used for modeling three component liquid (kerosene, kerosene and air, air). Calculationwas focused on tracking the dynamics of the axial force acting on the rotor auger centrifugal stage. The calculationshowed that the increasing of volume of gas lead to increases the amplitude fluctuations of axial force.</p>Combined pumpcentrifugal-auger stagenumerical simulationkerosene vapourcombined airaxial loadingКомбинированный насосшнекоцентробежная ступеньчисленный анализнерастворённый воздухпары керосинаосевая нагруженность
