Abstract:
1. An instability mitigation system for a rotor, the system comprising: a detection system comprising a sensor capable of generating an input signal corresponding to a flow parameter; a correlation processor that receives the input signal and a rotor speed signal and generates a stability correlation signal; a mitigation system that facilitates the improvement of the stability of the rotor when an onset of instability is detected by the detection system wherein the mitigation system comprises at least one plasma actuator mounted on a blade; and a control system for controlling the detection system and the mitigation system; wherein the control system comprises a controller that controls an AC potential applied to a first electrode and a second electrode of the plasma actuator; and wherein the controller controls the AC potential by pulsing the AC potential at a selected frequency.
