In this thesis, a general report is made on the cryogenic rocket engines of spaceships using liquid fuels and a detailed description on the technical characteristics of a turbopump. Simultaneously, studies of various turbopumps that were used in known rockets are reported and the new current developments are analyzed. Next, all the laws of fluid mechanics that apply to a turbopump are described, as well as all the coefficients that determine its geometric characteristics and its durability. Subsequently, the design methodology of a turbopump for pumping liquid hydrogen and oxygen in detail using the CFturbo program. Finally, the CFD
analysis for each component of the turbopump is conducted using the Simscale program. The results are evaluated, new suggestions for potential efficiency enhancements are proposed and general conclusions are drawn.
