Abstract

A preliminary analysis of F/A-18E Super Hornet static engine run-up noise measurements that shows evidence of nonlinear propagation effects was described. Evidence of nonlinear propagation was demonstrated by a comparison of measured spectra with free-field linear predictions and by calculation of a nonlinear indicator. Analysis of the F/A-18E static engine run-up measurements indicated that the noise is non-Gaussian and the propagation nonlinear at afterburner and military thrust conditions. The study has demonstrated that additional and perhaps more extensive investigations in this area are merited.
