Turbine engine including transfer gearbox and accessory gearbox

A turbine engine comprising:

• a fan section, a compressor section, a combustion section, and a turbine section in axial flow arrangement and defining a turbine engine axis of rotation, wherein the compressor section comprises a low-pressure compressor and a high-pressure compressor;
• an engine core defined by the compressor section, the combustion section, and the turbine section;
• an inner cowl circumscribing at least a portion of the engine core and radially spaced from the engine core to define an inner cowl space;
• an outer cowl circumscribing at least a portion of the inner cowl and spaced from the inner cowl;
• a transfer gearbox at least partially located in the inner cowl space;
• a first accessory device at least partially located in the inner cowl space and operably coupled to the transfer gearbox, wherein the first accessory device is located upstream of the combustion section;
• an accessory gearbox located in the outer cowl;
• a connection assembly operably coupling the accessory gearbox to the transfer gearbox, the connection assembly comprising:
• a first transfer shaft extending from the transfer gearbox to a first interface, the first transfer shaft having a first shaft centerline forming a first angle from the turbine engine axis of rotation when viewed from a plane containing both the first shaft centerline and the turbine engine axis of rotation, wherein the first angle is greater than 0° and less than 90° ;
• and
• a second transfer shaft extending from the accessory gearbox and coupled to a second interface rotatably driven by the first interface, wherein the second transfer shaft includes a second shaft centerline forming a second angle from the first shaft centerline when viewed from a plane containing both the second shaft centerline and the first shaft centerline, wherein the second angle is greater than 0° and less than 180°;
• a second accessory device operably coupled to the accessory gearbox and located in the outer cowl, wherein the second accessory device is upstream of the combustion section;
• and
• a heat exchanger located radially within the inner cowl space, wherein at least a portion of the heat exchanger axially overlaps a portion of a fan casing.
