Instrumented flow passage of a turbine engine

摘要

The invention relates to an annular air flow passage (33) for a turbine engine such as a turbojet or a turboprop, crossed by an instrumented rod (50) that includes means for measuring characteristics of a flow potentially traveling along the passage, said rod extending between an outer annular wall (48) and an inner annular wall (42) of the passage. According to the invention, outer connection means (60, 86) fasten an outer end (58) of the instrumented rod to the outer wall in a manner that is rigid in all directions, and inner connection means (62) fasten an inner end (56) of the instrumented rod to the inner wall, in a manner that is rigid in the circumferential direction and that has at least one degree of freedom to move in a first direction (51) extending between the inner and outer walls (42, 48) of the passage and having at least a radial component.
