Abstract: The present invention relates to an air data sensing probe (10) that has a cylindrical barrel (12) joined to a contoured strut section (16). The strut has leading (26) and trailing (32) edges formed along curved paths, and supports the cylindrical barrel (12) at a position spaced from a mounting surface (20) and facing upstream of relative air movement. The strut (16) has a rounded leading edge (26), and is generally ogival-shaped in cross section. There is a blended, relatively quickly-changing transition section (24, 40A) to blend the trailing end of the cylindrical barrel (12) into the ogival-shaped strut section (16) so that the probe (10) has reduced weight of the strut (16) and reduced drag, and through reduction of the cross-sectional area and rounding the strut leading edge (16), has enhanced anti-icing performance.

Abstract: Capteur (10) de données aérologiques devant être monté sur un véhicule aérien (14) et dont l'extrémité externe (11) est espacée vers l'extérieur à partir de la surface du véhicule aérien (14). Le capteur comprend une base de montage (12) et une extrémité externe (11) pourvue d'orifices de détection (21, 22) servant à détecter des paramètres de données aérologiques, le corps (32) du capteur (10) étant fabriqué de telle façon que, lorsqu'il est observé dans le plan de bissection du corps (32), les bords interne et externe (34, 36) du corps s'incurvent de manière continue à partir de l'extrémité externe (11) jusqu'à la base (12). Ces bords (34, 36) divergent à partir d'un endroit adjacent à l'extrémité externe (11) jusqu'à la base (12) afin de produire une sonde aux formes lisses et aérodynamiques (10) qui ont tendance à réduire la traînée.
