Abstract: A strut assembly for mounting an aerodynamic fairing assembly for attachment to a trailer of a tractor-trailer having a centerline, transverse structural support members extending between sides of the trailer, and longitudinal members extending along a length of the trailer. The strut assembly may comprise a mounting plate, a strut body, and a composite spring. The composite spring may be substantially rectangular. The mounting bracket comprising a mounting plate and a pair of spaced apart sidewalls. The strut body rotatably may be coupled to the pair of spaced apart sidewalls on the mounting bracket. The composite spring may be coupled to an upper surface of the strut body and configured to contact an underside of the mounting plate of the mounting bracket to resist inward deflection from an external force applied to the strut body.

Abstract: The aerodynamic skirt assembly for attachment to a trailer may comprise a side skirt fairing, a rear skirt fairing, and a secondary treatment. The side skirt fairing may comprise an inner surface and an outer surface. The rear skirt fairing may comprise an inner surface and an outer surface and located aft of the side skirt fairing. The secondary treatment may be coupled to the outer surface of the rear skirt fairing, wherein the secondary treatment is canted outwardly at an angle from the outer surface of the skirt fairing and configured to redirect the air around the at least one rear wheel assembly.
