Abstract: A plasma actuator includes a first electrode disposed on a substrate, covered by a dielectric layer, and a second electrode disposed on the dielectric layer. In operation, the plasma actuator creates a plasma region, altering air flowing over the actuator. The plasma actuator in various embodiments: has no moving parts, helps to improve fuel economy by reducing aerodynamic drag, improves vehicle stability control under severe unsteady flow environments, reduces wind noise around a vehicle on which the actuator is used, and reduces emission and CO2 foot print through the fuel economy improvement.

Abstract: A vehicle wheel assembly includes a vehicle wheel including a wheel body having a center. The vehicle wheel defines a plurality of openings arranged annularly around the center of the wheel body. The vehicle wheel assembly further includes a self-deployed wheel shutter system coupled to the vehicle wheel. The self-deployed wheel shutter system includes a hub plate, an annular rim disposed around the hub plate, and a plurality of shutter flaps. The shutter flaps are movable relative the vehicle wheel between an extended position and a retracted position. In the extended position, the shutter flaps cover the openings of the vehicle wheel to preclude air from flowing through the vehicle wheel. When the plurality of shutter flaps are in the retracted position, the openings are exposed, allowing the air to flow through the openings of the vehicle wheel.
