Abstract

Sonde de mesure aérodynamique destinée à mesurer une incidence locale de flux d'air circulant le long du fuselage d'un aéronef, comprenant un support (1) et un arbre mobile (2) en rotation selon un axe longitudinal (3), par rapport au support (1), le support (1) et l'arbre (2) étant configurés pour former entre eux un interstice (4), permettant de maintenir un jeu fonctionnel pour laisser pivoter librement une extrémité de l'arbre (2) dans le support (1), et communiquant avec un circuit d'évacuation d'impuretés, l'arbre (2) comprenant une partie (2a) interne au support (1), une partie (2b) girouette externe au support (1) et un plateau (2c) embase de la partie girouette (2b) reliant la partie interne (2a) et la partie externe (2b), le support (1) comprenant un capot (6) circulaire avec un ouverture centrale traversée par l'arbre mobile (2) la surface externe du capot (6) comprenant une face tronconique (6a) de révolution autour de l'axe longitudinal (3) de demi-angle au sommet de 84°, le plateau (2c) dépassant de l'extrémité interne de la surface externe du capot (6) d'une hauteur comprise entre 0,5 mm et 1 mm. Figures pour l’abrégé : Figure 3Aerodynamic measurement probe intended to measure a local incidence of air flow circulating along the fuselage of an aircraft, comprising a support (1) and a movable shaft (2) in rotation along a longitudinal axis (3), relative to the support (1), the support (1) and the shaft (2) being configured to form between them a gap (4), making it possible to maintain a functional play to allow one end of the shaft (2) to pivot freely in the support (1), and communicating with a circuit for evacuating impurities, the shaft (2) comprising a part (2a) internal to the support (1), a vane part (2b) external to the support (1) and a plate (2c) base of the vane part (2b) connecting the internal part (2a) and the external part (2b), the support (1) comprising a circular cover (6) with a central opening through which the movable shaft passes (2) the external surface of the cowl (6) comprising a frustoconical face (6a) of revolution around the longitudinal axis (3) of half-angle at the top of 84°, the plate (2c) protruding from the internal end of the outer surface of the cover (6) with a height of between 0.5 mm and 1 mm.
