Gas turbine engine fan bleed heat exchanger system

摘要

A heat exchanger system for a gas turbine engine includes: a fan (112) having at least two stages of rotating fan blades surrounded by a fan casing (114), the fan operable to produce a flow of pressurized air at a fan exit; at least one heat exchanger (116) having a first flowpath in fluid communication with the fan (112) at a location upstream of the fan exit; and a fluid system coupled to a second flowpath of the at least one heat exchanger (116). The first and second flowpaths are thermally coupled to each other.
