Aerodynamic fairings for cargo enclosures
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.

11. The cargo enclosure of claim 10 , further comprising a transition piece extending between an end of the nose fairing and an adjacent end of the side fairing.
12. The cargo enclosure of claim 1 , wherein the side fairing corresponds to a separate component configured to be separately installed on the cargo enclosure or is formed integrally with the cargo enclosure.
13. A kit for retrofitting an existing cargo enclosure, the cargo enclosure including a front wall, a rear wall and a sidewall extending between the front and rear walls, the cargo enclosure defining a side edge at the interface between the sidewall and the front wall, the kit comprising:
a side fairing configured to projected outwardly from the front wall and extend lengthwise at or adjacent to the side edge of the cargo enclosure, the side fairing including an outer wall, an inner wall and a leading edge region extending between the outer and inner walls, the outer wall extending away from the front wall at a location at or adjacent to the side edge,
