Abstract
In a mixed flow gas turbine engine of the type which includes an outer nacelle spaced apart from a core engine to define an annular bypass duct therebetween, there is provided a convoluted lobed mixer having a plurality of cold chutes in flow communication with the bypass duct and hot chutes in flow communication with the core engine. In order to suppress engine turbomachinery and exhaust noise, the mixer is alternatively provided with various combinations of acoustically treated lobes, spool pieces, radial splitters, and/or circumferential splitters. These acoustic treatments act in conjunction with an acoustically treated nozzle assembly and an acoustically treated plug assembly to provide an effective low aerodynamic pressure loss noise suppression system.
