A device for and method of measuring the flow velocity of a free fluid flow in three dimensions is provided in which a rotationally symmetrical flow body has at least two sets of peripherally spaced openings in regions of different thickness along the side of the body, with one of the sets preferably at or near the thickest region. Each set of openings communicates with a separate internal chamber in which the static pressure of the fluid from its openings is measured. In accord with the method of the invention, the differences in the static pressure thu...
A device for measuring the flow velocity of a free fluid flow in space, comprising an elongated aerodynamic flow body having a measuring head rotationally symmetrical about an axis and of varying thickness along said axis, said body defining an internal space divided by a partition into two chambers, said head having first and second sets of peripherally-spaced openings in the side of said head in spaced relationship with a foremost tip thereof, said first openings being located in a thicker region of said head and communicating with one of said chambers...
