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 translation: 本发明涉及一种具有连接到轮廓支柱部分（16）的圆柱形筒（12）的空气数据传感探针（10）。 支柱具有沿着弯曲路径形成的引导件（26）和尾部（32）边缘，并且在与安装表面（20）间隔开并面向相对空气运动的上游的位置处支撑圆柱形管体（12）。 支柱（16）具有圆形的前缘（26），并且横截面通常为椭圆形。 存在混合的，相对快速变化的过渡部分（24,40A），以将圆柱形筒体（12）的后端部分混合到椭圆形支柱部分（16）中，使得探头（10）的重量减轻 支柱（16）和减少的阻力，并且通过减小横截面积和使支柱前缘（16）四舍五入，具有增强的防冰性能。

Abstract: A short, strut-mounted, multifunction air data sensing probe (20) providing reduced drag, weight and radial cross section has a modular internal construction providing a multiple passageway pressure assembly (35) to transfer sensed pressure signals from individual sensing ports (25, 31, 32) on a probe barrel (21) to pressure carrying conduits (57, 62, 66, 73, 74) extending into the mounting strut (30) of the probe (20). The modular construction eliminates the need for having interior chambers made by fixing a series of difficult to locate bulkheads on the probe interior, with separate lines running from each of the chambers to provide the pressure signal from each of the ports. The modular construction also permits mounting a deicing heater (95) on internal parts other than the outer probe shell so that the manufacture of the probe (20) is furher simplified, and the types of material used for the probe shell (21) can be changed without concern about heater mounting.

Abstract: Une sonde (20) de détection de données aérodynamiques multifonctions, courte, fixée sur un montant, présentant une trainée, un poids et une section transversale radiale réduits comporte une structure interne modulaire ménageant un ensemble (35) sous pression à passages multiples, destiné à transférer des signaux de pression détectés provenant d'orifices individuels de détection (25, 31, 32) situés sur un cylindre (21) de sonde, à des conduits porteurs de pression (57, 62, 66, 73, 74) s'étendant dans le montant (30) de fixation de la sonde (20). La construction modulaire élimine la présence de chambres intérieures formées par la fixation d'une série de cloisons difficiles à placer à l'intérieur de la sonde, des lignes séparées partant de chacune des chambres afin de transmettre le signal de pression provenant de chacun des orifices. La construction modulaire permet également le montage d'une unité de chauffage de dégivrage (95) sur les parties internes autres que l'enveloppe extérieure de la sonde, de sorte que la fabrication de la sonde (20) est simplifiée davantage, et les types de matériau utilisés pour l'enveloppe de la sonde (21) peuvent être changés sans que cela ne pose de problème pour le montage de l'unité de chauffage.
