Plasma drag reduction


Food for thought...

Freebeard mentioned plasma actuators in another thread. I recalled reading about the effect some time ago. Searching on the web for more info, I came across this.

Technology | Plasma Stream

Our patented technology (s) uses an active flow control system utilizing plasma actuators has been developed at the University of Notre Dame. This system is capable of generating a body force which controls flow separation from a vehicle. By controlling flow separation, the drag force on a vehicle is minimized. In essence, a vehicle can be streamlined independent of its actual shape. Physical devices such as spoilers, bobtails, flow plates, and diverter tabs have been used to move the airflow in a desired direction. Plasma actuators ionize the local airflow to induce a similar affect without the added structural components or weight. Even the best designed physical devices attempt to divert flow, unlike plasmas which modify the existing flow field.
There are good videos in the link showing the effect.

Using plasma actuators to reduce drag in the future looks to be not only possible.

But, a glowing reality...
