Abstract
Abstract A pitot tube for taking a total head and a static pressure of an air flow. This probe comprises a tip having a streamlined nose surface which is provided with an opening for taking a total head, which surface smoothly transforms into a cylindrical surface provided with an opening for taking a static pressure. The above-said cylindrical surface is equipped with a ring for aerodynamic compensation of the errors appearing during the measurement of the static pressure.

A pitot tube probe for taking a total head and a static pressure of an air flow comprising in combination: a tip having a streamlined nose surface with an opening for taking a total head, smoothly transforming into a cylindrical surface having an opening for taking a static pressure, a ring producing a vacuum zone there behind and a high-pressure zone in front thereof, said ring being mounted on said cylindrical surface and located relative to said openings so as to compensate for an error in the measurement of the static pressure, the sign of the error being taken into account.
