    Abstract: An air data probe includes a probe head (102;202;302;402;602) and a raised portion (106;206;306;406;606). The probe head defines a longitudinal axis (A) and includes a forward tip (104;204;304;404;604) and a probe head surface (107;207;307;407;607). The raised portion is defined in the probe head surface aft of the forward tip. The raised portion is raised radially relative to the probe head surface. The raised portion is configured and adapted to trip a fluid boundary layer passing over the probe head to transition from laminar to turbulent for reducing boundary layer separation for consistent readings at high altitudes and/or high mach numbers. A method of manufacturing an air data probe includes forming a probe head and applying a raised portion to a surface of the probe head aft of the forward tip. Applying the raised portion to the surface of the probe head includes using brazing, additive manufacturing, adhesives and/or any other suitable technique.

    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.
