Abstract

A pitot tube includes a wall that extends longitudinally along an axis. The wall defines an inlet aperture at a longitudinal end of the wall, an outlet aperture opposite the inlet aperture, an interior cavity extending from the inlet aperture to an outlet aperture, a passage extending through and perpendicular to the wall having an outlet along an exterior surface of the wall, and an augmenting feature configured to reduce a static pressure at the outlet of the passage. In another embodiment, a wall defines a passage and an augmenting feature that modifies a flow direction of fluid flowing across an outlet of the passage such that a static pressure of the fluid at the outlet is reduced relative to the wall without the augmenting feature.
