“…Since 1977 KBKhA has designed boost turbopumps for liquid rocket engines. Seventeen boost turbopumps have been designed for different engines including the oxygen-hydrogen RD-0120 sustainer for Energiya launcher, the oxygen-hydrogen RD-0146 upper stage engine for Proton and Angara launchers, and the oxygen-kerosene upper stage engine for the Soyuz-2 launcher 1 .…”

Boost turbopumps for a ground test demonstrator engine developed by Pratt & Whitney have been built by Konstruktorskoe Buro Khimavtomatiyi (KBKhA) in cooperation with Pratt & Whitney. The paper discusses design approach, development results and design simplicity of the liquid hydrogen (fuel) and liquid oxygen (oxidizer) boost turbopumps (FBTP and OBTP). The paper describes element-wise experimental development principles used for the boost turbopumps which are based on component sub-assembly level testing in simulated conditions and fluids thus assuring low cost development and excluding the necessity to conduct all the tests with the real propellants. The OBTP and FBTP experimental characteristics are presented in this paper including comparison of the OBTP performance characteristics in water and in liquid oxygen and the FBTP rotor dynamics characteristics throughout the range of operating speeds. Element-wise development allows not only assuring fulfillment of design requirements but also to determine operability margins of the elements and identify the ways for possible design improvements.
