Abstract
A gas turbine engine includes an unducted primary fan, a core engine including a combustor casing enclosing a combustor and defining an outer surface, a core cowl surrounding the core engine. The core cowl has a cowl door. The 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). The core engine defines an overall core axial length (L) and an under-core cowl axial length (L). The gas turbine engine defines a core cowl diameter ratio (CDR) equal to the peak cowl diameter (D) divided by the maximum combustor casing diameter (d) and a core cowl length ratio (CLR) equal to the under-core cowl axial length (L) divided by the overall core axial length (L). The CDR is between 2.7 and 3.5 and the CLR is between 0.25 and 0.50.
