Abstract

Détecteur de direction de courant d'air comprenant une sonde rotative munie de deux séries d'orifices tels que 16 décalés angulairement et communiquant avec un carter. Une tige 21 est fixée dans un tube 20 et porte des saignées formant, avec le tube, des couloirs 24, 25, 27. Le couloir 25 réunit les orifices 16 à une ouverture 23 débouchant dans le carter. Le couloir 24 réunit les orifices 16 à un trou de vidange d'eau 22. L'impédance aérodynamique du couloir 24 est supérieure à celle du couloir 25. Application à la mesure de la direction du courant d'air relatif sur les aéronefs.Air flow direction detector comprising a rotary probe provided with two series of orifices such as 16 angularly offset and communicating with a housing. A rod 21 is fixed in a tube 20 and carries grooves forming, with the tube, passages 24, 25, 27. The passage 25 joins the orifices 16 to an opening 23 opening into the casing. The lane 24 joins the orifices 16 to a water drain hole 22. The aerodynamic impedance of the lane 24 is greater than that of the lane 25. Application to the measurement of the direction of the relative air flow on aircraft.
