Abstract

A gas turbine engine comprises a fan, a core engine coupled to the fan, a fan case housing the fan and the core engine, a plurality of outlet guide vanes extending between the core engine and the fan case, a blade effective acoustic length (BEAL), and an acoustic spacing. The fan comprises a fan disk, a fan diameter, and a plurality of fan blades. The acoustic spacing comprises a distance between the fan and the plurality of outlet guide vanes, and in combination with the BEAL determines an acoustic spacing ratio of the gas turbine engine. The fan case comprises an inlet, and in combination with the fan disk and fan diameter determines a disk spacing length and disk-to-blade diametric (DBD) ratio of the gas turbine engine.
