| 摘要 |
The present invention refers to an aerodynamic device (1) for reducing the drag of terrestrial vehicles, comprising at least one aerodynamic appendage (2) extending along a longitudinal axis (A), said at least one aerodynamic appendage (2) comprising: - a first aerodynamic surface (3) adapted to interact with the aerodynamic flow around said vehicle; - a second coupling surface (4), facing away from the first aerodynamic surface (3), adapted to fixedly couple the device (1) to a portion of said vehicle; wherein said aerodynamic surface (3), in a cross-section along a plane normal to said longitudinal axis (A), has an outline comprising: - a first length (5), adapted to face the front portion of the vehicle, gradually increasing to a maximum point (P); and - a second length (6) adapted to face the back portion of the vehicle, gradually decreasing from said maximum point (P), wherein at least said first length (5) of the first aerodynamic surface (3) is convex. |
