Wavepacket Modeling of the Jet Noise Source

This research is motivated by the need for physical models for the jet noise source to be used in practical noise prediction schemes for propulsion-airframe integration concepts. The emphasis is on jets with high-subsonic velocities typical of modern turbofan engines. The basis for the source model is an amplitude-modulated traveling wave the wavepacket. Its parameters are determined by minimiz...

Simple - source model of military jet aircraft noise 1 , 2

Described is a method for determining a semi-empirical, equivalent simple-source model that accounts for the aeroacoustic sources in the jet plumes of high-performance military aircraft. The characteristics of the equivalent source are guided by previously reported observations of jet noise, including an asymmetric, partially correlated source distribution and known far-field peak directivity a...

Simple-source model of military jet aircraft noise

This paper describes a method for determining a semi-empirical, equivalent simple-source model that accounts for the sound radiation in the vicinity of a high-performance military aircraft. The characteristics of the equivalent source are guided by previously reported observations of jet noise, namely that the strengths of the partially correlated sources are distributed asymmetrically. The par...
