Abstract

A bypass axial turbomachine includes a fan, a low pressure stator stage, a high pressure stator stage, the compressors being traversed by a flow referred to as primary flow of the turbomachine, at least one passage of discharge flow rate controlled from the primary flow in one of the stator stages toward the secondary flow, a heat exchanger of the surface air-oil (ACOC) type arranged flat on or in the wall surrounding the stator stages and defining the internal surface of the secondary flow, directly downstream of the junction of the passage of the discharge flow rate with said wall, so as to be run through by the secondary flow enriched with the discharge flow rate.

First claim

We claim:

1. A bypass axial turbomachine, comprising:
an axial compressor, the compressor being traversed by a flow referred to as primary of the turbomachine;
an annular wall surrounding the compressor and delineating an internal surface of a flow referred to as secondary of the turbomachine;
a passage configured to generate a discharge flow rate controlled from the primary flow in the compressor toward the secondary flow, the passage opening into the wall delineating the int…
