摘要： A system for determining an acoustic signature of a device is disclosed that includes a computer processor operable to determine strength and location of shock wave sound signals based on propagation of sound waves generated by the device. The strength and location of the shock wave signals are modified due to dissipation and dispersion effects in a non-uniform atmosphere. The shock wave signals are separated into even and odd numbered signals, and oscillations in the signals are smoothed by averaging even and odd numbered shock signals.

摘要： 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 each actuator. The controller is configured to cause at least one actuator to move the coupled flap assembly between the first and second positions at a determined frequency.
