Comparison of different plasma actuation strategies for aeroelastic control on a linear compressor cascade

Maria Grazia De Giorgi et al.

Summary: This paper investigates the effects of DBD plasma actuators on aeroelastic control of a subsonic compressor cascade, demonstrating that the phase of actuation force can effectively manipulate unsteady lift and moment coefficients, stabilize compressor performance, alleviate fatigue phenomena, and enlarge flutter limits. The study suggests that plasma actuators are a very promising technology for active flow control in turbomachines and aeronautical applications.
