Abstract

An analysis and generalization are carried out for properties of screw centrifugal pumps intended for liquid-propellant rocket engines in regard to turbining modes. This paper is keeping on the sequence of previous publications accomplished jointly by researchers from MAI and Energomash Corporation. Experimental data for the screw centrifugal pumps applying in liquid-propellant rocket engines are compared with data for pumps produced to use in another industrial applications. Obtained results allow to enhance numerical modeling accuracy to optimize lighting processes for designed and upgraded liquid-propellant rocket engines.
