Aerodynamic trucking systems
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.
1. An aerodynamic fairing assembly for attachment to a trailer of a tractor-trailer comprising a top, bottom, front, rear, a pair of sides, wheels having tires and brakes, and a trailer frame comprising a centerline and transverse structural support members extending between sides of the trailer, and having at least one rear wheel assembly situated below the trailer frame, the aerodynamic fairing assembly comprising:
a skirt fairing comprising an inner surface and an outer surface;
a secondary treatment coupled to the outer surface of the 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.
2. The aerodynamic fairing assembly of claim 1 , further comprising one or more mounting brackets configured to couple the skirt fairing to one or more or of the transverse structural support members.
3. The aerodynamic fairing assembly of claim 2 , wherein the mounting brackets rotatably couple the skirt fairing to one or more or of the transverse structural support members.
4. The aerodynamic fairing assembly of claim 1 , wherein the skirt fairing comprises a side skirt fairing and a rear skirt fairing.
5. The aerodynamic fairing assembly of claim 4 , wherein the secondary treatment is coupled to an outer surface of the rear skirt fairing.
6. The aerodynamic fairing assembly of claim 1 , wherein the side skirt fairing and rear skirt fairing are generally planar and formed by a plurality of sections.
7. The aerodynamic fairing assembly of claim 6 , wherein adjoining edges of the plurality of sections abut one another.
8. The aerodynamic fairing assembly of claim 1 , wherein the canted angle of the secondary treatment allows a linear path along a length of the trailer for the secondary treatment to be located outward of a linear path of the skirt fairing.
9. The aerodynamic fairing assembly of claim 8 , wherein the canted angle of the secondary treatment and orientation of the skirt fairing allows the secondary treatment to extend outwardly of a side of a trailer envelope.
10. The aerodynamic fairing assembly of claim 1 , wherein the secondary treatment comprises an outward protrusion from the outer surface of skirt fairing.
11. The aerodynamic fairing assembly of claim 1 , wherein the secondary treatment comprises a raised portion outwardly from the outer surface of the skirt fairing.
