-PI UTMOST) ABSTRACT This dissertation preliminary presents structure and capabilities of new integrated environment for axial compressors preliminary design in Stream. The environment makes possible to find number of different designs with inverse task solver, basing on initially specified boundary conditions, closing conditions and design variables. Design space explorer provides easy and visual comparison for range of obtained design in customizable coordinate axes.Solution filtering on different parameters, such as number of stages, meridian and axial dimensions, maximal blades weight, saving the time to choose from thousands obtained solutions the only one right design. After preliminary design also design flow and calculate all parameter in flow path with help of stream line solver and optimism. Blade twisting was also investigation with help of experimental calculation in Stream and optimization twist factor.

Also presents velocity triangles, enthalpy-entropy diagram and mass flow rate leakages.
