AIR DATA PROBES

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 transit...

Beschreibung
Zusammenfassung:	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. Une sonde de données dair comprend une tête de sonde définissant un axe longitudinal comprenant une pointe avant et une surface dinduction de turbulence définie par la tête de sonde à larrière de la pointe avant. La surface dinduction de turbulence est configurée et adaptée pour déclencher une couche limite de fluide passant par dessus de la tête de sonde pour faire la transition de laminaire à turbulent pour contrôler ou réduire la séparation de couche limite afin de produire des lectures uniformes à hautes altitudes.
