Plasma against turbulences

In order to develop airplanes with more lift and less air resistance, researchers from Darmstadt set on an unusual means.

Who flew already once, knows the massive flaps at the bearing areas of traffic machines, which drive themselves out with takeoff and landing, in order to increase the lift. Sven Grundmann would like to achieve the same effect with simple strips from copper tape.

Grundmann and its colleagues produce plasma with two copper strips, in between an isolating plastic film. To the copper electrodes they apply an alternating voltage by approximately ten kilovolts. Thus develops an electrical field, which produces the air of the environment partly ionized and a violet glow. At the same time the loaded air particles are accelerated by the electrical field. Thereby they take-away air molecules slower.
