FIELD: machine building.
SUBSTANCE: present invention relates to an assembly (2) with blades (1), in particular of straightening unit for turbomachine compressor. Assembly (2) with blades (1) contains multiple individual devices (14A) acting on a flow, which are formed so as to generate swirling (16). Each of said individual devices (14A) is provided at inlet of said unit (2) with blades (1) so as to simultaneously affect main flow (E) and recirculation flow (G).
EFFECT: reduced tearing obtained due to present invention allows to improve efficiency of compressor (3) and widens range of stability.
