Abstract: The invention relates to an instrumented airfoil for mounting in a flow passage through a turbine, compressor, or module of a turbine engine. An instrumentation member is attached to an airfoil and includes information-obtaining means received in a cutout formed in the airfoil and projecting relative to the leading edge or the trailing edge. According to the invention, the instrumentation member also comprises a holder portion that is united with the information-obtaining means and that is attached to the cutout in such a manner that its surface is in alignment respectively with the suction side wall, the pressure side wall, and the leading edge or the trailing edge of the airfoil, the transitions between these respective surfaces not presenting any setbacks.

Abstract: A vane intended to be mounted in a supply fluid pattern, includes a blade delimited in a lateral direction by an outer surface, the blade housing a data routing channel and having a groove leading to the outer surface and which communicates with the data routing channel, and data collecting means for collecting data on one of the outer surface of the blade and the vicinity thereof, the data collecting means being connected, through the groove, to the data routing channel, or extending there through. The data collecting means include one of an inserted tube and a cable, and the groove is formed in one of the outer surface opposite that whereto the inserted tube and the cable leads, and the blade that includes an orifice passing therethrough the outer surface.

Abstract: A vane intended to be mounted in a supply fluid pattern, the vane comprising: a blade delimited in a lateral direction by an outer surface having an upper surface and an lower surface which are joined at ends, so as to form there a leading edge and a trailing edge respectively, the blade housing a channel for routing data and having a groove leading to at least one of the upper surface and lower surface walls and which communicates with the data routing channel, and data collecting means for collecting data on one of the outer surface of the blade and the close vicinity thereof, the data collecting means being connected, through the groove, to the data routing channel, or extending therethrough, wherein the data collecting means comprises one of an inserted tube and a cable, and the groove is formed in one of the upper surface and lower surface wall opposite that whereto said one of the tube and the cable leads, and the blade is gone through by an orifice provided between the upper surface and the lower su
