Abstract: An aerodynamic fairing for a cargo body is adapted to decrease drag generated by the moving cargo body. The fairing has a top wall providing a surface for guiding air thereover; and members extending away from the top wall, with bottom parts of the members, distant to the top wall, providing a mounting surface to mount the fairing to the cargo body. The fairing can be mounted to the cargo body using brackets allowing the fairing to expend and contract freely and to span over the whole width of the cargo body. The top fairing is economical to produce, being potentially made of extruded material.

Abstract: There is described a top fairing for a trailer adapted to decrease drag and manage water. The top fairing comprises a surface for guiding air thereover, comprising a leading flange; a leading surface having a leading radius, the leading surface being joined to the leading flange and extending in a rearward direction; and a tailing surface having a tailing radius, the tailing surface in continuity to the leading surface in the rearward direction. The top fairing comprises openings disposed in the leading flange for managing water through the leading flange.

Abstract: An aerodynamic skirt assembly is described therein, the aerodynamic skirt assembly comprising a ribbed skirt panel with at least one rib associated with the ribbed skirt panel to alter mechanical properties of the ribbed skirt panel, wherein the rib is providing a longitudinal stiffness of a thinner ribbed skirt panel that is comparable to a thicker non-ribbed skirt panel while allowing momentarily elastic deformation of the ribbed skirt panel when the ribbed skirt panel is contacting a foreign object while returning automatically to a non-deformed configuration when the ribbed skirt panel is not contacting the foreign object.

Abstract: This invention relates to an actuated aerodynamic air drag reducing apparatus for reducing the air drag of a vehicle, the actuated aerodynamic air drag reducing apparatus being adapted to move between an expanded configuration and a retracted configuration by an actuator on a basis of a signal associated to the behavior of the vehicle. The actuator being connected to a slider selectively connected to a pair of pivotable elongated members for being used between a plurality of configurations.
