INLET - NAI EXHAUST HOLE DEFINITION FOR REDUCED D-DUCT RESONANCE NOISE AND DILUTED EXHAUST PLUME FOR THERMAL CONTROL
FIG1 illustrates a perspective view of an aircraft in accordance with various embodiments
In various embodiments and with reference to FIG1, an aircraft 100 may comprise a fuselage 112 and a pair of wings 114. A propulsion system 120 (e.g., a turbofan gas turbine engine with a nacelle assembly) may be coupled to the aircraft 100 (e.g., mounted on the underside of a wing 114). The propulsion system 120 may be configured to provide at least one of forward thrust or propulsion for the aircraft 100.
