Abstract

An analysis and generalization are carried out for properties of boost pumps intended for liquid-propellant rocket engines in regard to turbining and braked shaft modes. Experimental data for the boost pumps case are compared with data for pumps produced to use in another industrial applications. Obtained results allow to enhance significantly numerical modeling accuracy to optimize lighting processes for designed and upgraded liquid-propellant rocket engines.
