Aerodynamic fairings for cargo enclosures
A nose fairing for a cargo enclosure may generally include a nose body configured to extend outwardly from a front wall of the enclosure. The nose body may include an upper nose wall, a lower nose wall and a leading edge region extending between the upper and lower nose walls. The upper nose wall may include a concave region that terminates at the leading edge region such that the nose fairing transitions directly from the concave region of the upper nose wall to the leading edge region. The lower nose wall may include a convex region that terminates at the leading edge region such that the nose fairing transitions directly from the convex region of the lower nose wall to the leading edge region. The leading edge region may define a radius of curvature that differs from a radius of curvature of the convex region of the lower nose wall.
1. A cargo enclosure for storing cargo, the cargo enclosure including a front wall, a rear wall and a roof extending between the front and rear walls, the cargo enclosure defining a top edge at the interface between the front wall and the roof, the cargo enclosure further comprising:
a nose fairing including a nose body extending in a lengthwise direction along the front wall between a first end and a second end of the nose body, the nose body including an upper nose wall, a lower nose wall and a leading edge region extending between the upper and lower nose walls, the upper nose wall extending away from the front wall at a location at or adjacent to the top edge of the cargo enclosure, the upper nose wall including a concave region defining a concavely curved surface and the lower nose wall including a convex region defining a convexly curved surface; and
a firsts end cap installed adjacent to the first end of the nose body such that the first end cap projects outwardly from the first end of the nose body in the lengthwise direction;
wherein the first end cap is configured to mate with the first end of the nose body and close off an inner cavity that is defined between the nose body and the front wall of the cargo enclosure; and
wherein the first end cap is configured to accommodate a lighting device at a location spaced apart from the first end of the nose body in the lengthwise direction.
2. The cargo enclosure of claim 1 , wherein at least a portion of the first end cap defines a curved profile substantially corresponding to a profile of the nose body.
3. The cargo enclosure of claim 2 , wherein the curved profile of the first end cap includes a concave portion substantially corresponding to the concave region of the upper nose wall and a convex portion substantially corresponding to the convex region of the lower nose wall.
4. The cargo enclosure of claim 2 , wherein the first end cap transitions from the curved profile to a shape corresponding to a shape of a front corner of the cargo enclosure.
5. The cargo enclosure of claim 4 , wherein the first end cap is configured to accommodate the lighting device at a location adjacent to the front corner of the cargo enclosure.
6. The cargo enclosure of claim 4 , wherein the first end cap is configured to at least partially wrap around the front corner of the cargo enclosure.
7. The cargo enclosure of claim 1 , wherein the first end cap defines a recessed surface spaced apart from the first end of the nose body that is configured to accommodate the lighting device.
8. The cargo enclosure of claim 1 , further comprising a second end cap installed adjacent to the second end of the nose body such that the second end cap projects outwardly from the second end of the nose body in the lengthwise direction, the second end cap being configured to accommodate a second lighting device at a location spaced apart from the second end of the nose body in the lengthwise direction.
9. The cargo enclosure of 1 , wherein the leading edge region defines a radius of curvature that differs from a radius of curvature of the convex region of the lower nose wall.
10. The cargo enclosure of 1 , wherein upper nose wall further includes an upper convex region defining a convexly curved surface, the upper nose wall transitioning from the upper convex region to the concave region as the nose body extends outwardly from the front wall in the direction of the leading edge region.
11. A kit for retrofitting an existing cargo enclosure, the cargo enclosure including a front wall, a rear wall and a sidewall extending between the front and rear walls, the cargo enclosure defining a side edge at the interface between the sidewall and the front wall, the kit comprising:
a nose fairing including a nose body configured to extend in a lengthwise direction along the front wall between a first end and a second end of the nose body at a location at or adjacent to the top edge of the cargo enclosure, the nose body including an upper nose wall, a lower nose wall and a leading edge region extending between the upper and lower nose walls, the upper nose wall including a concave region defining a concavely curved surface and the lower nose wall including a convex region defining a convexly curved surface; and
a first end cap configured to be installed adjacent to the first end of the nose body such that the end cap projects outwardly from the first end of the nose body in the lengthwise direction;
wherein the first end cap is configured to mate with the first end of the nose body and close off an inner cavity that is defined between the nose body and the front wall of the cargo enclosure.
12. The kit of claim 11 , wherein at least a portion of the first end cap defines a curved profile substantially corresponding to a profile of the nose body.
13. The kit of claim 12 , wherein the curved profile of the first end cap includes a concave portion substantially corresponding to the concave region of the upper nose wall and a convex portion substantially corresponding to the convex region of the lower nose wall.
14. The kit of claim 12 , wherein the first end cap transitions from the curved profile to a shape corresponding to a shape of a front corner of the cargo enclosure.
15. The kit of claim 14 , wherein the first end cap is configured to accommodate a lighting device at a location adjacent to the front corner of the cargo enclosure.
16. The kit of claim 14 , wherein the first end cap is configured to at least partially wrap around the front corner of the cargo enclosure.
17. The kit of claim 11 , wherein the first end cap is configured to accommodate a lighting device at a location spaced apart from the first end of the nose body in the lengthwise direction.
18. The kit of claim 17 , wherein the first end cap defines a recessed surface spaced apart from the first end of the nose body that is configured to accommodate the lighting device.
19. The kit of claim 11 , further comprising a second end cap configured to be installed adjacent to the second end of the nose body such that the second end cap projects outwardly from the second end of the nose body in the lengthwise direction.
20. The kit of claim 11 , wherein the upper nose wall further includes an upper convex region defining a convexly curved surface, the upper nose wall transitioning from the upper convex region to the concave region as the nose body extends outwardly from the front wall in the direction of the leading edge region.
