Small Turbine Engine Noise Reduction. Volume III. Suppression Design and Prediction Methodology/Materials Tests.
Abstract
The volume reviews the published theoretical background from a number of sources to present a uniform approach to duct and lining sound-attenuation prediction. It further reviews the results of a wide variety of acoustical tests of lining materials and configurations. The final development of an applicable technology for small gas turbine duct attenuator design and attenuation prediction is included, along with comparison to actual turbopropulsion duct test data.
