Vehicle bodywork with high speed stability - has grooves of half venturi form in its lower surface to channel air flow

摘要

The bodywork (1) of a self-propelled vehicle is constructed to improve stability at high speed by forming the lower surface (6) witht wo grooves (10) of half-venturi form in longitudinal section, to channel the air-flow under the vehicle. The grooves are limited laterally by rigid sides (11), and are arranged symmetrically on either side of the bodywork. Each groove has an increasing depth towards the rear, and extends from the lowest part of the lower surface as far as its rear end. Each groove extends for the greater part of the length of the lower surface. The bodywork is provided along its lower side edges with resistant flexible sides formed by strips of material.
