This paper deals with application of the data reduction method at a sliding data technique. It offers to study the influence of non-periodic processes in the flow field of blade cascade namely on the value of loss coefficients. The operational regime of the blade cascade is characterized by transonic and supersonic exit velocity. The experimental data analysis concerns pneumatic measurements with aim to calculate the total pressure and the kinetic energy loss coefficients, and to evaluate these coefficients with respect to the aperiodicity of the flow field. The flow structure is also studied on the basis of results obtained by means of optical methods, such as schlieren technique and interferometry.
