Abstract

Drag reducing means adapted to be mounted on the roof of the cab portion of a land vehicle including a trailing body for reducing aerodynamic drag. The drag reducing means comprises a streamlined fairing including a bottom portion, a rear portion, a nose portion and a continuous contoured surface extending widthwise and upwards from the nose portion to the rear portion. The contoured surface has a top portion and side portions which abut at their respective boundaries. The top portion has a segment the tangential plane of which is inclined with respect to the horizontal at an angle which is less than or equal to approximately tan-1¢2(H-h)/x! and greater than or equal to zero, where H represents the vertical distance from the roof of said cab portion to a top wall of said trailing body, h represents the height of said fairing, x represents the distance between the rear portion of said fairing and the front of said trailing body, and h has a value greater than or equal to about .9H and less than H. The fairing is also designed so the segment of the top portion is located furthest from the bottom portion.
