Abstract:
The invention relates to a turbine engine comprising: a first splitting edge capable of separating an incoming air stream into a radially internal air stream and a secondary air stream; a second splitting edge capable of separating the radially internal air stream into a primary stream and a tertiary stream which traverses a tertiary-stream flow path that is radially external to a primary-stream flow path traversed by the primary stream; a heat exchanger (18) arranged in the tertiary-stream flow path; and an inner casing (28); characterized in that the exchanger comprises an upstream portion (50) comprising a collar (52) which projects from a body (32) of the exchanger in the upstream direction, the collar being accommodated in a floating manner in a groove (54) that runs circumferentially in the inner casing.
