Title:
TRIPLE-FLOW AXIAL TURBOMACHINE WITH HEAT EXCHANGER
Document Type and Number:
WIPO Patent Application WO/2024/061737
Kind Code:
A1
Abstract:
The invention relates to a turbomachine comprising: a first splitting edge capable of separating an incoming air flow into a radially internal air flow and a secondary air flow; a second splitting edge capable of separating the radially internal air flow into a primary flow and a tertiary flow which traverses a tertiary flow path that is radially external to a primary flow path traversed by the primary flow; a heat exchanger (18) arranged in the tertiary flow path; and an inner casing (28); characterized in that the exchanger comprises a body (32) and a flange (32.1) which extends radially inside and projects from the body, the flange being attached to the inner casing, the exchanger comprising, downstream of the flange, a downstream portion (40) to which a fire wall (46) forming a heat shield is attached.
