Patent attributes
A plasma spoiler is mounted in a rear portion of a vehicle for exerting a force on a passing air flow. The plasma spoiler has a dielectric substrate formed of a dielectric material, a first electrode mounted on a bottom surface of the dielectric substrate and insulated by the dielectric substrate, a second electrode mounted on an upper, exposed surface of the dielectric substrate, and a power source connected to the first and second electrodes. The first electrode is disposed in a rearward direction relative to the second electrode. A switch is disposed between the power source and one of the first electrode and the second electrode. The switch is controlled by a controller that is in communication with a speed sensor, so as to activate the plasma spoiler only when the vehicle exceeds a trigger speed.
