Abstract
A system for heat exchange and leak detection is generally provided, the system including a heat exchanger including a first wall defining a first passage containing a first fluid. A leak detection enclosure containing a leak detection medium is defined between the first wall and a second wall surrounding the first wall.
Claims21
A gas turbine engine comprising:
- a fan assembly;
- a core engine disposed downstream of the fan assembly and comprising a core engine casing, a compressor section downstream of the fan assembly, a combustion section downstream of the compressor section, and a turbine section downstream of the combustion section;
- a fan bypass airflow passage disposed downstream of the fan assembly and outside of the core engine casing;
- a core flowpath disposed within the core engine casing and defined through the compressor section, the combustion section, and the turbine section;
- a third stream bypass airflow passage disposed between the fan bypass airflow passage and the core flowpath that bypasses at least a portion of the core engine;
- and
- a system for heat exchange and leak detection,
- wherein airflow from the fan assembly is split between a first portion that enters the fan bypass airflow passage, and a second portion that enters the core engine casing,
- wherein the second portion is split within the core engine casing between the core flowpath and the third stream bypass airflow passage,
- wherein an entirety of the airflow passing through the third stream bypass airflow passage merges with the airflow of the fan bypass airflow passage at an axial position that is axially forward of at least a portion of the turbine section, and
- wherein at least a first portion of the system for heat exchange and leak detection is disposed in the third stream bypass airflow passage.
