Abstract: A multi-panel skirt system for a flatbed includes two pair of forward and aft skirt panels with each pair located on an opposite lateral sides of the flatbed. In each pair, the forward skirt panel extends along the lateral side edge generally in the lengthwise direction between a leading edge and a trailing edge, which is located adjacent to and aligned with or positioned laterally inboard of the lateral side edge of the flatbed. An aft skirt panel extends along the lateral side edge generally in the lengthwise direction between a leading edge and a trailing edge aft of the forward skirt panel, which trailing edge is located adjacent to and aligned with or positioned laterally inboard of the lateral side edge. The leading edge of the aft skirt panel is positioned laterally inboard of the trailing edge of the forward skirt panel.

Abstract: A nose fairing for a cargo enclosure may generally include a nose body configured to extend outwardly from a front wall of the enclosure. The nose body may include an upper nose wall, a lower nose wall and a leading edge region extending between the upper and lower nose walls. The upper nose wall may include a concave region that terminates at the leading edge region such that the nose fairing transitions directly from the concave region of the upper nose wall to the leading edge region. The lower nose wall may include a convex region that terminates at the leading edge region such that the nose fairing transitions directly from the convex region of the lower nose wall to the leading edge region. The leading edge region may define a radius of curvature that differs from a radius of curvature of the convex region of the lower nose wall.
