The designed approach to decision of the problem has allowed with united poses-purpose to consider the flows in running parts of the different form, including event of the methods as one should decision of the system of the Euler's equations recorded in stationary form. Computing process stability is provided by articifial compressibility introduction. The relative motion flow Mach number does not exceed 1.45. Methods have an advantage over existing ones on count time and computer resources. The designed calculation methods using will allow raising the quality and reducing the time of the design works. Aviation engines and power plant units statistical models elements, which can be used as part of gas turbine engines mathematical models, are designed. Accuracy increasing of the axial compressors steady work criterions does possible their using at forecasting of the multistage axial compressors features. The further methods improvement of the study unsteady models gives the base to testing accuracy increasing of appearance such modes and safety increasing of appearance such modes and safety increasing of appearance such modes and safety increasing to usages compressor and gas turbine technology.
