초록

A jet engine adapted for reducing far-field noise levels is disclosed. The jet engine has a plurality of flap assemblies that are disposed around a perimeter of an exhaust port of the jet engine. Each flap assembly is movable between a first position and a second position. The jet engine also includes a plurality of actuators respectively coupled to the plurality of flap assemblies. Each actuator is configured to selectively move the coupled flap assembly between the first and second positions. The jet engine also includes a controller that is coupled to...
