Five-Hole Pressure Probes

Description

Five-hole pressure probes, or pitot tubes, measure the pressure simultaneously at five points on a small bluff object (typically a sphere a few centimeters in diameter) mounted on a rod. This pressure information can be converted to a wind vector using a wind tunnel calibration. Other shapes, such as wedges and cones, have also been used. These probes have been deployed on towers, aircraft, and unmanned aerial vehicles for turbulence measurements. Wildmann et al. (2014) provide a useful introduction to the design and deployment of a five-hole probe on an unmanned aerial vehicle.
