description: This work is devoted to determination of local and integral parameters of axial pump of L-1170 type. The main purpose of the work is to design an axial pump of L-1170 type, determination of its parameters and verification of the universal characteristic. On the basis of available theoretical drawings of the impeller and the straightening wheel, solid models of the vane system (VS) and a liquid model of the flow part (FV) were created in the SolidWorks graphical editor. The calculation area was discretized in the grid generator TurboGrid. Calculation parameters of the mathematical model in the Ansys CFX software were worked out and numerical calculations were performed with the help of computational fluid dynamics methods. During the study the following tasks were solved: determination of the basic parameters in the steady-state and non-steady-state formulation, construction and verification of the universal characteristic of the pump, development of the axial pump design for 3 angles of blades installation, discretization of calculation models, visualization of resulting calculations, investigation on cavitation, strength calculations. The object of the research is to consider calculation issues of the axial pump of L-1170 type, for which there were theoretical drawings of the impeller and straightener, as well as experimental characteristics.
