vortex generators for vortex generation upstream of a cascade of compressor blades

摘要

Vortex generators for vortex generation upstream of a cascade of compressor blades. The present invention relates to a blade assembly (2), particularly a flow stabilizer, for a turbomachine compressor, said blade assembly (2) comprising a plurality of individual devices (1). 14a) which has an action in the flow, which is formed in such a way that at least it generates vortices (16). It is characterized in that each of said individual devices (14a) is provided upstream of said blade assembly (2) so as to act simultaneously on the main flow (e) and recirculating flow (g). .
