Zusammenfassung:	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.12 cl, 8 dwg Настоящее изобретение относится к узлу (2) с лопатками (1), в частности, спрямляющего аппарата для компрессора турбомашины. Узел (2) с лопатками (1) содержит множество индивидуальных устройств (14А), воздействующих на поток, которые сформированы таким образом, чтобы создавать завихрения (16). Каждое из упомянутых индивидуальных устройств (14А) предусмотрено на входе упомянутого узла (2) с лопатками (1) так, чтобы одновременно воздействовать на основной поток (Е) и на рециркуляционный поток (G). Уменьшение отрывов, полученное благодаря изобретению, позволяет улучшить кпд компрессора (3) и способствует увеличению диапазона стабильности. 3 н. и 9 з.п. ф-лы, 8 ил.
