Abstract

L'invention concerne un dispositif de mesure (1) de paramètres d'un flux aérodynamique d'une turbomachine (60) qui est destiné à être fixé sur une paroi (62, 63) de la turbomachine et à s'étendre radialement depuis cette paroi dans le flux aérodynamique, le dispositif de mesure (1) comprenant un corps (3) structural d'axe radial portant des moyens de relevé d'informations (2) destinés à relever des informations relatives aux paramètres du flux aérodynamique. Selon l'invention, le corps comprend un évidement (22) formant une première portion de paroi (23) et une deuxième portion de paroi (24) opposées et espacées l'une de l'autre, le dispositif de mesure comprenant une pièce rapportée (4) qui est montée par complémentarité de forme dans l'évidement et qui est destinée à former en partie un bord de fuite du corps, la pièce rapportée étant installée dans l'évidement avec un jeu (J) défini entre le corps et la pièce rapportée, et le dispositif de mesure comprenant un organe de mise en précontrainte (5) configuré pour précontraindre au moins la première portion de paroi de sorte à réduire ledit jeu.The invention relates to a device (1) for measuring the parameters of an aerodynamic flow of a turbomachine (60) which is intended to be fixed to a wall (62, 63) of the turbomachine and to extend radially from this wall in the aerodynamic flow, the measuring device (1) comprising a structural body (3) of radial axis carrying information reading means (2) intended to collect information relating to the parameters of the aerodynamic flow. According to the invention, the body comprises a recess (22) forming a first wall portion (23) and a second wall portion (24) opposite and spaced from each other, the measuring device comprising an insert. (4) which is mounted by complementary shape in the recess and which is intended to partially form a trailing edge of the body, the insert being installed in the recess with a clearance (J) defined between the body and the insert, and the measuring device comprising a prestressing member (5) configured to prestress at least the first wall portion so as to reduce said play.
