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.
