Patent

CA 2710000

A compression system (18) is disclosed, the compression system comprising a stator stage (31) having a row of a plurality of stator vanes (31) a arranged around a centerline axis (8). each stator vane (31) having a vane airfoil (35) and at least one plasma actuator (82) located on the stator stage (31). Exemplary embodiments of a detection system (500) for detecting an instability in a compression system rotor (12a) and a mitigation system (300) that facilitates the improvement of the stability of the rotor (12a) are disclosed.

L'invention concerne un système de compression (18), ledit système de compression comprenant un étage de stator (31) doté d'une rangée d'une pluralité d'aubes de stator (31) agencées autour d'un axe de ligne médiane (8). Chaque aube de stator (31) comprend un profil aérodynamique d'aube (35) et au moins un actionneur plasma (82) placé sur l'étage de stator (31). Des exemples de modes de réalisation d'un système de détection (500) pour détecter une instabilité dans un rotor de système de compression (12a) ainsi qu'un système d'atténuation (300) qui améliore la stabilité du rotor (12a) sont décrits.
