Title: Airflow management in future design

Abstract: Ford|s Probe 111 research vehicle was created as a result of a research project aimed at integrating optimum aerodynamic efficiency and aesthetics. Extensive windtunnel tests demonstrated that a semi-fastback body shape with a fully covered underbody performed best. The elimination of all protrusions and gaps between the glass and sheet metal surfaces has resulted in high air velocity in this area. Spoilers are employed at the rear of the car to force the air into a favourable separation behaviour. The result is that airflow disruption is avoided. The exterior mirrors were designed with an integral aerofoil profile in the lower area of the plastic housing. This ensures that there is only a short turbulence wake behind the mirror. A movable Venturi belly pan further reduces the Probe 111|s drag coefficient.

Keywords: vehicle design; airflow management; drag reduction; drag coefficient; integrated accesories; Venturi belly pan.
