Measurement instrument support interposed between a drive unit and an air intake of an aircraft nacelle

An aircraft nacelle comprising:

• a power plant comprising a pipe with an aerodynamic surface;
• an air intake configured to channel a stream of air toward said power plant, said air intake comprising an inside pipe with an aerodynamic surface configured to contact the stream of air;
• and
• an annular support of at least one measuring device, said annular support comprising an aerodynamic surface and a U-shaped cross-section with a base and two branches;
• wherein:
• said annular support is removably inserted downstream of said air intake and upstream of said power plant in a direction of flow of the stream of air, in such a way as to ensure continuity of said aerodynamic surface of the air intake, said aerodynamic surface of the annular support, and said aerodynamic surface of the power plant;
• the base of the U-shaped cross-section of the annular support comprises, for each of said at least one measuring devices, a through hole opening on the aerodynamic surface of the annular support;
• and
• each through hole receives a measuring device, such that said measuring device is maintained essentially perpendicular to the aerodynamic surface of the annular support, wherein an end of said measuring device is essentially flush with said aerodynamic surface of the annular support, so as not to interfere with the stream of air.
