Abstract
A gas turbine engine comprises a fan assembly, a core engine coupled to the fan assembly, a fan case housing the fan assembly and the core engine, a plurality of outlet guide vanes extending between the core engine and the fan case, and an acoustic spacing. The fan assembly comprises a plurality of fan blades that define a fan diameter and a blade effective acoustic length (BEAL). The acoustic spacing comprises a distance between the fan assembly and the plurality of outlet guide vanes, and in combination with the BEAL determines an acoustic spacing ratio of the gas turbine engine. A gearbox assembly with an improved engine efficiency rating used in combination with the acoustic spacing provides an improved and balanced engine architecture.
