    摘要: L'invention concerne une sonde de mesure d'incidence locale destinée à être fixée à une paroi (11) et un procédé mettant en oeuvre la sonde. La sonde (10) comprend au moins cinq prises de pression (16, 17, 18) disposées sur un nez (15) du corps de sonde (13), des moyens de mesure de pression associés aux prises de pression (16, 17, 18) et des moyens de calcul aptes à déterminer une incidence de l'écoulement par rapport à la direction principale (14) du corps de sonde (13) en fonction des pressions mesurées par les moyens de mesure de pression. Selon l'invention, les moyens de calcul sont configurés pour choisir parmi les prises de pression (16, 17, 18) celles permettant d'obtenir la meilleure précision de mesure de l'incidence locale et pour calculer l'incidence locale par rapport à la direction principale (14) à partir des mesures de pression effectuées dans les prises de pression choisies (16, 17).

    摘要: The present invention discloses a pressure measurement device (1000) comprising: a substrate that includes at least one pressure sensing module and at least one fluid-conductive channel, wherein each channel has a first aperture and a second aperture. The substrate is flexible such that the pressure measurement device (1000) is conformably adjustable onto an object's surface. The first aperture is located on the substrate such that when the substrate is suitably adjusted onto the object's surface, the first aperture is open to the exterior of the object's surface. The pressure sensors module is operatively connected to at least one of the second apertures, such that the at least one pressure sensing module is generally being subjected to the pressure being present at the first aperture.
