description: Gas compressor units (GCUs) have been rapidly developing. Creation of modern, reliable and highly efficient GPU with a long service life is the most important link in the newest concept of resource extraction development. The currently achieved high degree of perfection of the GPU vane apparatus does not leave significant reserves for a further increase in efficiency. At the same time, centrifugal wheels, in which there are irreversible pressure losses, are characterized by significant reserves for increasing efficiency, so this topic is relevant. The aim of the work is to consider the methods and recommendations based on the generalization of the results obtained in the work for the design of the flow paths of the inlet ducts, stages of the centrifugal compressors of the GPU. Identifying the best measurement method. Tasks to be solved to achieve the goal: - review and analysis of literature; - consideration of the aerodynamic qualities of the inlet paths of loaded compressor stages; - complex numerical and experimental studies; - comparison of methods for measuring three-dimensional flow; - Formulate conclusions. The scientific novelty of the work is manifested in the fact that this study discusses recommendations on design methods for highly efficient centrifugal compressor stages. The practical significance of this research work of the master's thesis lies in the fact that it is a master's thesis and meets the requirements of the curriculum. The dissertation "Improving the efficiency of inlet ducts, stages and outlet diffusers of stationary gas turbines" (Chernikov VA, Rassokhin VA) is used as the main literature. It describes the need to develop generalized recommendations, directions and methods for designing flow paths of important elements of power gas turbines [1]. The objective of this study is to obtain experimental gas-dynamic characteristics of model stages of centrifugal compressors.
