Abstract
A gas turbine engine includes an unducted primary fan and an engine core having a combustor casing that defines an outer surface. A core cowl surrounds the core engine where an accessory gearbox is at least partially located within the core cowl. In a radial direction, an outer surface of the core cowl defines a peak cowl diameter (D), and the outer surface of the combustor casing defines a maximum combustor casing diameter (d). A core cowl diameter ratio (CDR) is the peak cowl diameter (D) divided by the maximum combustor casing diameter (d) and is between 2.7 and 3.5. In an axial direction, the core engine defines an overall core axial length (L) and an under-core cowl axial length (L1). A core cowl length ratio (CLR) is the under-core cowl axial length (L1) divided by the overall core axial length (L) and is between 0.25 and 0.50.
