    Abstract: An air data probe (10) includes a probe body (18) and an air data sensing port (20) disposed in the probe body (18). The probe body (18) includes a barrel region, a tapered head region extending forward from the barrel region, and a tip at a forward-most end of the tapered head region. The air data sensing port (20) is disposed in the probe body (18) at a port location aft of the tip. The probe body (18) has a turbulence-producing geometry originating at the tip that produces a turbulent boundary layer of airflow that extends from the tip to the port location.

    Abstract: An air data probe (46) has a pitot tube with a tap (47) at a forward end (48) that defines an inner flow path. The inner flow path decreases in the cross-sectional area until reaching a throat (50). Bleed holes (52) or slots are provided to eliminate air recirculation and boundary layer separation. The outer surface of the tube may comprise a relatively flat portion and a bulged portion, or a long-nosed portion of smaller diameter and an enlarged portion.
