Abstract
A heat exchange module is provided for a turbine engine. The heat exchange module includes a duct and a plurality of heat exchangers. The duct includes a flowpath defined radially between a plurality of concentric duct walls. The flowpath extends along an axial centerline through the duct between a first duct end and a second duct end. The heat exchangers are located within the flowpath, and arranged circumferentially around the centerline.
Claims15
A turbine engine with an axial centerline, comprising:
- a heat exchange module that includes:
- a duct including a duct flowpath defined radially between a plurality of concentric duct walls, the duct flowpath extending along the axial centerline and through the duct between a first duct end and a second duct end;
- and
- a plurality of heat exchangers arranged circumferentially around the axial centerline,
- wherein each heat exchanger of the plurality of heat exchangers is configured to pivot substantially 90 degrees between a deployed position extending radially across the duct flowpath and a stowed position;
- the turbine engine including a first case, a second case, and a third case, wherein a central core flowpath is defined by the first case;
- wherein a primary bypass flowpath is defined radially between the first case and the second case;
- wherein a secondary bypass flowpath is defined radially between the second case and the third case;
- and
- wherein the duct flowpath is fluidly coupled inline with the secondary bypass flowpath.
