Abstract

As it was established in works [1–4], mutual circumferential shift of stators in a system of rows stator (IGV)-rotor (R)-stator (S) of the axial compressor significant change of pressure pulsations on the rotor blades and in a stream causes (clocking effect). It is possible to expect that similar change of pressure pulsations influences also on the noise, radiated by the specified system of rows. The given work is devoted to an experimental research of influence of stators clocking on the noise, radiated by rows upwards on a stream.
