Ferrous Fibre Network Materials for Jet Noise Reduction in Aeroengines Part I: Acoustic Effects
Source abstract
Abstract
An investigation is presented into the acoustic effects of introducing tubular modules, made of highly porous ferrous materials, into the exhaust region of a gas turbine engine. It is shown that substantial reductions in noise level (up to ∼10 dB) can be achieved, at constant thrust. Such effects can arise both via modification to the gas flow field (and hence to noise generation characteristics) and by attenuation of acoustic waves within the modules.
