Abstract

An apparatus for monitoring at least one performance characteristic of a component of a vehicle may include a tripod connected to an exterior surface of the vehicle, the tripod includes a plurality of airfoils defining an aerodynamic surface of the tripod, a camera positioned on the tripod at a predetermined viewing angle directed toward the component of the vehicle and a camera fairing connected to the tripod and surrounding the camera, the camera fairing includes a sidewall defining an aerodynamic surface of the camera fairing, an aperture disposed through the sidewall and aligned with the camera and a plurality of protrusions positioned proximate the aperture.

Claims

1. An apparatus for monitoring at least one performance characteristic of a component of a vehicle, said apparatus comprising:

a camera fairing comprising an upstream end and a downstream end, and defining an internal volume, said camera fairing comprising;

a sidewall defining a camera fairing-aerodynamic surface;

an aperture disposed through said sidewall; and

a plurality of protrusions projecting outwardly from said sidewall, wherein each one of said plurality of protrusions extends from proximate said aperture toward said upstream end of said camera fairing approximately aligned with a streamline direction of an airflow passing over said camera fairing from said upstream end to said downstream end, and wherein said each one of said plurality of protrusions adjoins an adjacent one of said plurality of protrusions.

2. The apparatus of claim 1 wherein said each one of said plurality of protrusions has a length, along said streamline direction, and a convex-curved cross-sectional profile, perpendicular to said length, having a radius.

3. The apparatus of claim 2 wherein said radius of adjacent ones of said plurality of protrusions is different.

4. The apparatus of claim 2 wherein said radius of said each one of said plurality of protrusions is different.

5. The apparatus of claim 1 wherein said plurality of protrusions form a wavy pattern on said aerodynamic surface.

6. The apparatus of claim 1 further comprising an imaging system, said imaging system comprising:

a camera positioned within said internal volume of said camera fairing and aligned with said aperture; and

a computer communicatively connected to said camera.

7. The apparatus of claim 6 further comprising a camera enclosure positioned within said internal volume of said camera fairing, said camera enclosure comprising a plurality of sidewalls defining a sealed internal volume,

wherein said camera is positioned within said sealed internal volume of said camera enclosure.

8. The system of claim 7 further comprising a tripod, said tripod comprising a forward leg and a pair of aft legs defining a tripod-aerodynamic surface,

wherein said camera enclosure is connected to said tripod, and

wherein said camera fairing is connected to said tripod surrounding said camera enclosure.

9. The apparatus of claim 2 wherein an inter-region disposed between adjacent ones of said plurality of protrusions comprises a concave-shaped cross-sectional profile.

10. The apparatus of claim 2 wherein said radius is between approximately 0.12 inch and approximately 0.5 inch.

11. The apparatus of claim 10 wherein said radius is between approximately 0.2 inch and approximately 0.24 inch.

12. The apparatus of claim 2 wherein:

an uppermost one of said plurality of protrusions comprises a largest radius,

a lowermost one of said plurality of protrusions comprises a smallest radius, and

each successive one of said plurality of protrusions between said uppermost one and said lowermost one comprises a gradually decreasing radius from said largest radius to said smallest radius.

13. The apparatus of claim 2 wherein:

an uppermost one of said plurality of protrusions comprises a smallest radius,

a lowermost one of said plurality of protrusions comprises a largest radius, and

each successive one of said plurality of protrusions between said uppermost one and said lowermost one comprises a gradually increasing radius from said smallest radius to said largest radius.

14. The apparatus of claim 1 wherein said plurality of protrusions at least partially surrounds said aperture.

15. The apparatus of claim 1 wherein said each one of said plurality of protrusions is approximately parallel to said adjacent one of said plurality of protrusions.

16. The apparatus of claim 1 wherein said each one of said plurality of protrusions has a height, and wherein said height gradually decreases from proximate said aperture toward said upstream end of said camera fairing.

17. The apparatus of claim 16 wherein said height is between approximately 0.08 inch and approximately 0.22 inch.

18. The apparatus of claim 16 wherein said height of at least one of said plurality of protrusions is different than at least another one of said plurality of protrusions.

19. The apparatus of claim 1 wherein said length of said each one of said plurality of protrusions is between approximately 2 inches and approximately 3 inches.

20. The apparatus of claim 19 wherein said length of at least one of said plurality of protrusions is different than at least another one of said plurality of protrusions.
