Abstract

A measuring comb for temperature and/or pressure and/or chemical composition of the gases flowing at the outlet of a turbine engine flow path, in which the flow path extends around an axis of revolution of the flow path, is provided. The measuring comb includes: a comb body with an elongated shape, intended to face the outlet of the flow path, the comb body including at least one measuring opening arranged along an axis, the measuring opening being configured to tap gases flowing at the outlet of the flow path; and an adjusting system configured to adjust an angle between the axis of the at least one measuring opening and the axis of revolution, so as to allow orientation of the at least one measuring opening in the flow direction of the gases at the outlet of the flow path.

First claim

1 - 9 . (canceled)

10 . A measuring comb for temperature and/or pressure and/or chemical composition of the gases flowing at the outlet of a turbine engine flow path, said flow path extending around an axis of revolution of the flow path, said measuring comb comprising:
a comb body with an elongated shape, intended to face the outlet of the flow path, said comb body comprising at least one measuring opening arranged along an axis, the measuring opening being configured to tap gases flowing at the outlet of the flow path; and adjusting means configured to adjust an angle between the axis of the at least one measuring opening and the axis of revolution, so as to allow orientation of the at least one measuring opening in the flow direction of the gases at the outlet of the flow path.

11 . The measuring comb according to claim 10 , wherein the comb body is a rod forming a rotation line around which the at least one measuring opening is capable of pivoting.

12 . The measuring comb according to claim 11 , wherein the rotation line formed by the rod is rectilinear.

13 . The measuring comb according to claim 11 , wherein the rotation line formed by the rod is curved.

14 . The measuring comb according to claim 11 , wherein the rod is equipped with a plurality of modules each accommodating a measuring opening, the modules being configured to pivot around the rod independently from each other.

15 . The measuring comb according to claim 10 , further comprising an arm configured to adjust a tilt of the comb body at the outlet of the flow path with respect to the axis of revolution of the flow path.

16 . The measuring comb according to claim 15 , comprising a plurality of measuring openings, the axes whereof extend in a same plane, the arm being configured to adjust a tilt of the comb body at the outlet of the flow path with respect to the axis of revolution of the flow path, so that the plane of the axes of the measuring openings and the axis of revolution form a non-zero angle.

17 . The measuring comb according to claim 16 , wherein the axes of the measuring openings extend generally in the shape of a fan.

18 . The measuring comb according to claim 10 , wherein the at least one measuring opening is connected to a measuring instrument configured for measuring temperature and/or pressure and/or chemical composition of the gases tapped by the at least one measuring opening.
