AIR DATA PROBE WITH MEANS FOR REDUCING BOUNDARY LAYER SEPARATION

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 su...

Beschreibung
Zusammenfassung:	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.
