Abstract: An aerodynamic drag reduction system includes a side panel configured to be coupled to a rear swing door to extend generally vertically at least partially along a height of a trailer and a top panel configured to be coupled to the rear swing door to extend generally horizontally at least partially along a width of the trailer. The drag system includes a cable system configured to connect the side and top panels to prevent upward movement of the top panel beyond its generally horizontal position. The cable system includes a first cable with a first end coupled to an inner surface of the side panel, and a second cable and a third cable each with a first end coupled to a bottom surface of the top panel. A second end of each of the first cable, the second cable, and the third cable is coupled together at a juncture.

Abstract: A trailer having a storage container, a landing gear assembly coupled to the storage container, and a rear wheel assembly coupled to the storage container includes a side skirt system for reducing drag on the trailer. The side skirt system includes a side skirt wall configured to be coupled to one side of the trailer to extend below one side wall of the trailer at least partially along a length of the trailer. A length of the side skirt wall along a top edge of the side skirt wall is approximately 48%-80% of a distance between the landing gear and forward-most position of the rear wheel assembly.

Abstract: A side skirt system for reducing drag on a trailer or other ground vehicle includes plurality of wall panels each configured to be coupled to one side of the trailer to extend generally below a storage container of the trailer at least partially along a length of the trailer. The wall panels are horizontally spaced-apart from each other.

Abstract: An aerodynamic rear drag reduction system of the present disclosure is configured to be coupled to a rear frame assembly of a trailer including a rear frame and a rear swing door. The drag reduction system includes a side panel configured to be coupled to the rear swing door to extend generally vertically at least partially along a height of the trailer; and a folding mechanism coupled to the side panel. The folding mechanism moves the side panel between (i) a fully-deployed position wherein the side panel is configured to extend generally rearwardly away from the rear end of the trailer and (ii) a fully-stowed position wherein an inner surface of at least a portion of the side panel is configured to lie generally adjacent the rear swing door. The folding mechanism is configured to be coupled to a door locking mechanism of the trailer for movement therefrom.

Abstract: An aerodynamic rear drag reduction system of the present disclosure is configured to be coupled to a rear frame assembly of a trailer including a rear frame and a rear swing door. The drag reduction system includes a top panel configured to be coupled to the rear swing door of the trailer and a hinge configured to couple the top panel to the rear swing door. The hinge includes a planar bracket configured to be coupled to the rear swing door, an L-shaped bracket configured to be coupled to the top panel, and a hinge joint configured to couple together the planar bracket and the L-shaped bracket. The hinge joint is configured to rotate about a pivot axis that is substantially parallel to a top edge of the rear frame of the trailer when the top panel is coupled to the rear swing door.

Abstract: An aerodynamic skirt system for reducing drag on a trailer includes a first side skirt wall and a second side skirt wall each configured to be coupled to one side of the trailer to extend generally below a storage container of the trailer at least partially along a length of the trailer.
