摘要：
Results of researches of blade rows unsteady interaction in the three-rows stage of the axial compressor are presented with the purpose of definition the gas-dynamical mechanism of clocking effects in system of rows stator-rotor-stator. Experiments were carried out on the large-dimensional low-speed compressor with measurements of stationary and unsteady flow parameters. Mutual circumferential position of stator rows, axial gaps and numbers of blades in rows are varied. Results of measurements are compared to calculation of flow parameters, received on the half-analytical theory of potential-vortical interaction of the airfoil cascades and by numerical simulation of averaged on Reynolds 2-D unsteady Navier-Stokes equations.
