INSTABILITY MITIGATION SYSTEM USING STATOR PLASMA ACTUATORS

摘要

An instability mitigation system 700 is disclosed, comprising a stator stage 31 located axially proximate to a rotor 12a, the stator stage 31 having a row of a plurality of stator vanes 31a arranged around a centerline axis 8, and a mitigation system 300 comprising at least one plasma actuator 82 mounted on the stator vane 31a that facilitates the improvement of the stability of the rotor 12a, and a control system 74 for controlling the operation of the mitigation system. An instability mitigation system further comprising a detection system 500 for detecting an onset of an instability in a rotor 12a and a control system 74 for controlling the detection system and the mitigation system are disclosed.
