Abstract: A pitot-static device, comprising first and second pluralities of hollow spokes extending in a radial direction from a central hub, the hollow interiors of the spokes of the first plurality being connected so as to allow fluid communication therebetween, and at least all but one of the spokes of the first plurality having at least one aperture facing in a first axial direction that is transverse to the radial direction, and the hollow interiors of the spokes of the second plurality being connected so as to allow fluid communication therebetween, and at least one of the spokes of the second plurality having an aperture at an end portion thereof that faces in the radial direction.

Abstract: A handheld airflow measurement device is provided that employs pitot-static principles instead of an anemometer. A pitot-static device has the advantage that it needs no moving parts and has little or no inertia. In a first aspect, therefore, a pitot-static device comprises a first plurality of hollow spokes and a second plurality of hollow spokes, the spokes of the first plurality being connected so as to allow fluid communication between their hollow interiors and each having at least one aperture facing in a first axial direction that is transverse to the radial direction, the spokes of the second plurality being connected so as to allow fluid communication between their hollow interiors and each having at least one aperture facing in a second axial direction that is opposed to the first axial direction. Such a device can be made symmetrical, meaning that it can be assembled from two identical half-mouldings.
