چکیده
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 angle. The parameters of the equivalent source model are chosen to reproduce the data recorded on large planar apertures in the near-field of an F-22A Raptor. Peak axial locations and relative contributions of the correlated and uncorrelated portions of the equivalent source are chosen to replicate the directionality and

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...
متن کاملPhased-array measurements of full-scale military jet noise
Beamforming techniques for aeroacoustics applications have undergone significant advances over the past decade to account for difficulties that arise when traditional methods are applied to distributed sources such as those found in jet noise. Nevertheless, successful source reconstructions depend on array geometry and the assumed source model. The application of phased-array algorithms to grou...
متن کاملModel for Military Jet Noise Jessica
This study explores an alternative approach using a semi-empirical equivalent simple-source model to analyze and characterize the turbulence-induced aeroacoustic sources from military jet aircraft. Initially the model is a single point source located above a hard plane such that the locations of destructive interference from its mirror image matched the measured interference nulls. This provide...
متن کاملNoise measurements in the near field of a high-performance military jet aircraft
Published near-field analyses of full-scale jet noise are limited, and the application of observed laboratory scale phenomena to full-scale jets is not well understood. To obtain a greater understanding of the connection between radiated noise and source characteristics in full-scale, heated, supersonic jets produced by military aircraft, acoustical measurements were made in the geometric near ...
متن کاملNonlinear Evolution of Noise from a Military Jet Aircraft during Ground Run-up
Nonlinear propagation of noise measured during static run-up measurements of a military jet aircraft is considered. Measurements made of the noise radiation from the F35AA Joint Strike Fighter indicate levels commensurate with finite-amplitude sound propagation, both through a Gol’dberg number analysis and numerical modeling. Comparisons with a nonlinear propagation model based on the generaliz...
