Abstract: An air data probe includes a probe body and an air data sensing port disposed in the probe body. The probe body 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 is disposed in the probe body at a port location aft of the tip. The probe body 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 includes a probe head and a raised portion. The probe head defines a longitudinal axis and includes a forward tip and a probe head surface. 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 translation: 空气数据探头包括探针头和凸起部分。 探针头限定纵向轴线并且包括前端和探针头表面。 凸起部分限定在前端后部的探针头表面中。 凸起部分相对于探针头表面径向地升高。 凸起部分被构造和适于使通过探针头的流体边界层跳跃以从层流转变成湍流，以便减少边界层分离，以在高海拔和/或高马赫数处获得一致的读数。 制造空气数据探头的方法包括形成探针头并将凸起部分施加到前部尖端的探针头的表面。 将凸起部分应用于探头的表面包括使用钎焊，添加剂制造，粘合剂和/或任何其它合适的技术。

Abstract: An air data probe includes a probe head defining a longitudinal axis with a forward tip, and a turbulence inducing surface defined in the probe head aft of the forward tip. The turbulence inducing surface is configured and adapted to trip a fluid boundary layer passing over the probe head to transition from laminar to turbulent to control or reduce boundary layer separation resulting in consistent readings at high altitudes.
Abstract translation: 空气数据探头包括限定具有前部尖端的纵向轴线的探针头和限定在前部尖端的探头头部中的湍流诱导表面。 湍流诱导表面被配置和适于使通过探针头的流体边界层跳过从层流到湍流转变，以控制或减少边界层分离，导致在高海拔处的一致读数。
