Title:
TRIPLE-FLOW AXIAL TURBOMACHINE COMPRISING A DIVERGING HEAT EXCHANGER IN THE THIRD FLOW
Document Type and Number:
WIPO Patent Application WO/2023/099527
Kind Code:
A1
Abstract:
The invention relates to an axial turbomachine (2), comprising: a first splitter (10) able to separate an incoming air flow (F) into a radially internal air flow (F') and into a radially external air flow, termed secondary flow (F2); a second splitter (14) able to separate the radially internal air flow into a primary flow (F1) and into a tertiary flow (F3) in a tertiary flow duct (16) radially to the outside of the primary flow; and a heat exchanger (18) arranged in the tertiary flow duct; characterized in that the heat exchanger extends radially and axially in an upstream portion (20) of the tertiary flow duct, having a divergent longitudinal section, the tertiary flow duct comprising a downstream portion (22) having a convergent longitudinal section, along the tertiary flow.
