Abstract: Systems, methods and media for reducing the aerodynamic drag of vehicles are disclosed. More particularly, embodiments may include at least one fan for directing air into a lower pressure region behind a vehicle in motion in order to reduce pressure drag. Embodiments may also include one or more internal air ducts for directing air from other parts of the vehicle to the at least one fan. In one embodiment, the operation of the at least one fan may be controlled based on sensed conditions, user control, or other means.

Abstract: Systems, methods and media for reducing the aerodynamic drag of vehicles are disclosed. More particularly, a control system for a pressure drag reduction system for a vehicle is disclosed. Embodiments may include a machine-accessible medium containing instructions to receive input relating to a vehicle and to determine an improved pressure drag reduction system configuration based on the received input. Received input may include pressures, vehicle speed, user inputs, or other information. Embodiments may also include instructions to change the configuration of the pressure drag reduction system based on the determined improved configuration. In some embodiments, the operation of fans or ducts of the pressure drag reduction system may be controlled.

Abstract: Systems, methods and media for reducing the aerodynamic drag of vehicles are disclosed. More particularly, a method for reducing the pressure drag of a vehicle is disclosed. Embodiments may include capturing air from the airflow around the vehicle when the vehicle is moving and directing air from a first location to a second location. Embodiments may also include forcing the captured air from the second location into a lower pressure region to reduce pressure drag associated with movement of the vehicle in a direction, where the lower pressure region is created in response to movement of the vehicle. Further embodiments may include where directing the air includes directing the air through a duct internal to the vehicle or through a duct attached to the vehicle.
