Aerodynamic system and adjustable fairings
Embodiments provide an aerodynamic fairing system that may comprise a base configured to mount to a vehicle, an arm coupled to the base at a proximate end and extending laterally, an a fairing mounted to the arm having an inboard and an outboard surface. The fairing outboard surface may provide an aerodynamic outer surface to direct flow to an angle to the rear. The arm may a fixed or adjustable length arm. The arm may provide a mounting area for a mud flap such that aerodynamic system may act as a mud flap hanger. Embodiments also provide an adjustable mud flap hanger.
1. A fairing assembly adapted to couple to a vehicle, the assembly comprising:
an arm configured to be coupled to a frame of a vehicle; and
a fairing coupled to the arm, the fairing positioned on an outboard side of the vehicle, the fairing having an inboard surface and an outboard surface, the fairing outboard surface comprising an aerodynamic outer surface to direct longitudinal air flow in a rearward angle.
2. The fairing assembly of claim 1 , wherein the fairing is adjustably mounted to the arm.
3. The fairing assembly of claim 2 , wherein the fairing is adjustable horizontally, vertically or rotationally.
4. The fairing assembly of claim 1 , wherein the arm is adjustable longitudinally.
5. The fairing assembly of claim 1 , wherein the arm is deflectable relative to a vehicle frame.
6. The fairing assembly of claim 1 , wherein the fairing has a continuous aerodynamic surface from a leading edge to a trailing edge.
7. The fairing assembly of claim 6 , wherein the leading edge or trailing edge is curved to accommodate a tire.
8. The fairing assembly of claim 7 , wherein the fairing is shaped to fit between tires on a tandem axle.
9. The fairing assembly of claim 1 , wherein the fairing is shaped for use on either side of the vehicle.
10. The fairing assembly of claim 1 , wherein the arm comprises one or more mud flap mounts to mount a mud flap.
11. A method for providing a fairing assembly on a vehicle, comprising:
coupling an arm to a frame of a vehicle; and
coupling a fairing to the arm, wherein the fairing is positioned on an outboard side of the vehicle, the fairing having an inboard surface and an outboard surface, the fairing outboard surface comprising an aerodynamic outer surface to direct longitudinal air flow in a rearward angle.
12. The method of claim 11 , wherein the fairing is adjustably mounted to the arm.
13. The method of claim 12 , wherein the fairing is adjustable horizontally, vertically or rotationally.
14. The method of claim 11 , wherein the arm is adjustable longitudinally.
15. The method of claim 11 , wherein the arm is deflectable relative to a vehicle frame.
16. The method of claim 11 , wherein the fairing has a continuous aerodynamic surface from a leading edge to a trailing edge.
17. The method of claim 16 , wherein the leading edge or trailing edge is curved to accommodate a tire.
18. The method of claim 17 , wherein the fairing is shaped to fit between tires on a tandem axle.
19. The method of claim 11 , wherein the fairing is shaped for use on either side of the vehicle.
20. The method of claim 11 , wherein the arm comprises one or more mud flap mounts to mount a mud flap.
