초록

In a method of controlling vortex breakdown on an aerodynamic surface, a vortex generated by the aerodynamic surface is continually monitored to identify a non-linear region where vortex breakdown occurs. A fluid jet is blown into the non-linear region to displace the vortex breakdown to a target location. A blowing parameter for the fluid jet is continually adjusted to continually direct the fluid jet into the vortex breakdown region and preferably ensure maximum positive feedback. The fluid jet is dynamically displaced toward the sensitive spot to maxi...
