Abstract

In one embodiment, a probe includes a first facet associated with a first pressure port operable to measure a first wind pressure, a second facet associated with a second pressure port operable to measure a second wind pressure, and a third facet associated with a third pressure port operable to measure a third wind pressure. The second facet is adjacent to the first facet and the third facet adjacent to the second facet. The probe further includes a fourth facet adjacent to the third facet and a fifth facet adjacent to the fourth facet and to the first facet. The first facet, the second facet, the third facet, the fourth facet, and the fifth facet are located between a first end portion and a second end portion of the probe.

First claim

What is claimed is:

1. A probe, comprising:
a first flat facet associated with a first pressure port operable to measure a first wind pressure; and
a second flat facet associated with a second pressure port operable to measure a second wind pressure;
wherein:
the first flat facet and the second flat facet are located between a first end portion and a second end portion of the probe;
the first flat facet is adjacent to the second flat facet;
the probe is coupled to a vehicle; and
a surface of each of the first flat facet and the second flat facet of the probe faces away from a longitudinal centerline of the vehicle.

2. The probe of claim 1 , further comprising a third facet associated with a third pressure port operable to measure a third wind pressure, wherein a surface of the third facet of the probe faces away from the longitudinal centerline of the vehicle.

3. The probe of claim 1 , wherein:
the first end portion comprises a third pressure port operable to measure a third wind pressure; and
the third wind pressure is a reference pressure.

4. The probe of claim 1 , wherein the first flat facet and the second flat facet are machined surfaces.

5. The probe of claim 1 , wherein:
the first end portion is a cone-shaped tip comprising a first end;
the second end portion is a cylindrical base comprising a second end; and
a maximum length from the first end to the second end is eight inches.

6. The probe of claim 1 , wherein the first pressure port and the second pressure port are located the same distance from the first end portion.

7. The probe of claim 1 , wherein the probe is a solid object comprising at least one of the following materials:
aluminum;
steel; and
plastic.

8. A method, comprising:
measuring a first wind pressure using a first pressure port associated with a first flat facet of a probe; and
measuring a second wind pressure using a second pressure port associated with a second flat facet of the probe;
wherein:
the first flat facet and the second flat facet are located between a first end portion and a second end portion of the probe;
the first flat facet is adjacent to the second flat facet;
the probe is coupled to a vehicle; and
a surface of each of the first flat facet and the second flat facet of the probe faces away from a longitudinal centerline of the vehicle.

9. The method of claim 8 , further comprising measuring a third wind pressure using a third pressure port associated with a third facet of the probe, wherein a surface of the third facet of the probe faces away from the longitudinal centerline of the vehicle.

10. The method of claim 8 , further comprising measuring a third wind pressure using a third pressure port, wherein:
the first end portion comprises the third pressure port; and
the third wind pressure is a reference pressure.

11. The method of claim 8 , wherein the first flat facet and the second flat facet are machined surfaces.

12. The method of claim 8 , wherein:
the first end portion is a cone-shaped tip comprising a first end;
the second end portion is a cylindrical base comprising a second end; and
a maximum length from the first end to the second end is eight inches.

13. The method of claim 8 , wherein the first pressure port and the second pressure port are located the same distance from the first end portion.

14. The method of claim 8 , wherein the probe is a solid object comprising at least one of the following materials:
aluminum;
steel; and
plastic.

15. One or more computer-readable storage media embodying instructions that, when executed by a processor, cause the processor to perform operations comprising:
measuring a first wind pressure using a first pressure port associated with a first flat facet of a probe; and
measuring a second wind pressure using a second pressure port associated with a second flat facet of the probe;
wherein:
the first flat facet and the second flat facet are located between a first end portion and a second end portion of the probe;
the first flat facet is adjacent to the second flat facet;
the probe is coupled to a vehicle; and
a surface of each of the first flat facet and the second flat facet faces away from a longitudinal centerline of the vehicle.

16. The one or more computer-readable storage media of claim 15 , the operations further comprising measuring a third wind pressure using a third pressure port associated with a third facet of the probe, wherein a surface of the third facet faces away from the longitudinal centerline of the vehicle.

17. The one or more computer-readable storage media of claim 15 , the operations further comprising measuring a third wind pressure using a third pressure port, wherein:
the first end portion comprises the third pressure port; and
the third wind pressure is a reference pressure.

18. The one or more computer-readable storage media of claim 15 , wherein the first flat facet and the second flat facet are machined surfaces.

19. The one or more computer-readable storage media of claim 15 , wherein:
the first end portion is a cone-shaped tip comprising a first end;
the second end portion is a cylindrical base comprising a second end; and
a maximum length from the first end to the second end is eight inches.

20. The one or more computer-readable storage media of claim 15 , wherein the first pressure port and the second pressure port are located the same distance from the first end portion.
