Abstract:

The highly tonal noise spectra produced by Open Rotor (OR) engines differ greatly from the relatively smooth, atonal noise spectra produced by typical Turbofan (TF) engines. Understanding the effects of these spectral differences on received noise is necessary for the prediction of the impact on community noise that this new engine may have. In this study, representative OR spectra were parametrically generated with characteristics and variations modeling those seen in the published OR data (Hoff 1990). With this generated range of representative spectra, two primary studies were performed. The first study examined the relationship between instantaneous noise metrics for representative TF and OR spectra while the second study explored the differences in noise contour area for representative TF and OR operations at equal certification levels.
