Abstract

The article presents a method for improving the characteristics of fuel pump of rocket engine by the joint usage of mathematical optimization software IOSO, meshing complex NUMECA and CFD program ANSYS CFX. The optimization software was used for automatic change of the geometry of low-pressure impeller, transition duct and high-pressure impeller to find the optimal design. The original variant of the remaining parts of the pump was kept. For this reason, only geometrical parameters of the blades were varied without changing the contours of the pump meridional flow part.
