The invention concerns a device for the <i>in situ</i> angular positioning of an angle-of-attack sensor, of the vane type provided with a flag (121) and fixed on an aeroplane (Av). The invention is characterised in that it consists in directly using the rotation axis DELTA s of the sensor (12) as positioning reference. The angular positioning device comprises a fixed annular structure (3) secured (33-330-331, 34-340-341) to the wall of the aeroplane (Av), comprising a circular track (31, 32) for a mobile cursor (4). The flag (121) is locked in an enclosing structure (5a). A member (7) coupling the cursor (4) and the enclosing structure (5a) is fixed thereon. The coupling is provided by a flat spring clip (71) comprising a pin (72) on its end. The pin (72) is passed through a slot (412) of the cursor (4), thereby enabling the flag (121) to be driven about its axis of rotation ( DELTA s). The position is measured with a digital inclinometer (6).

L'invention concerne un dispositif de positionnement angulairein situ d'une sonde d'incidence (12), du type à girouette munie d'un drapeau (121) et montée sur un avion (A v). Selon l'invention, on utilise directement l'axe de rotation (.DELTA.s) de la sonde (12) comme référence de positionnement. Le dispositif de positionnement angulaire comprend une structure fixe (3) assujettie (33--330-331, 34-340-341) à la paroi de l'avion (A v), de forme annulaire (30) et comportant une piste circulaire (31, 32) pour un curseur mobile (4). Le drapeau (121) est bloqué dans une structure enveloppante (5.alpha.). Un organe de couplage (7) entre le curseur (4) et la forme enveloppante (5.alpha.) est fixé sur cette dernière. Le couplage est réalisé par une lame de ressort plat (71) comportant un ergot (72) sur son extrémité. L'ergot (72) est enfilé dans une fente (412) du curseur (4), ce qui permet l'entraînement du drapeau (121) autour de son axe de rotation (.DELTA.s). La mesure de position est obtenue à l'aide d'un inclinomètre numérique (6).
