摘要： A turbine engine resonator comprising a panel and a vessel. The panel is along a flow path within the engine and has an aperture. The vessel has a mounting flange secured to the panel. The flange has an aperture mated to the aperture of the panel. The vessel has a body secured to the mounting flange with an interior of the body in communication with the flange aperture. A first portion of the panel extends into the mounting flange aperture and may redirect a leakage flow, if any, to limit an effect of leakage upon resonator performance.

摘要： An acoustic liner 20 includes a remote panel 26, a perforated proximate panel 22 transversely spaced from the remote panel and one or more partitions 32 spanning across the space between the panels. At least one baffle 44 cooperates with the partitions to define a resonator chamber 34b and an associated neck 56 for establishing communication between the resonator chamber and a fluid stream G flowing past the proximate panel.

摘要： An acoustic liner 20 includes a remote panel 26, a proximate panel 28 transversely spaced from the remote panel and a resonator chamber 34b residing between the panels. Perforations 38 penetrate the proximate panel in registration with the resonator chamber 34b. A neck 56 with an inlet 58 recessed from the proximate panel establishes communication between the chamber and a fluid stream G flowing past the proximate panel. A bypass coolant passage 66 guides coolant through the perforations without guiding it through the resonator chamber.

摘要： A cooled acoustic liner useful in a fluid handling duct includes a resonator chamber 52 with a neck 56, a face sheet 86, and a coolant plenum 80 residing between the face sheet and the chamber. Coolant bypasses the resonator chamber, rather than flowing through it, resulting in better acoustic admittance than in liners in which coolant flows through the resonator chamber and neck. In one embodiment, the liner also includes a graze shield 88. Openings 40, 38 penetrate both the face sheet and the shield to establish a relatively low face sheet porosity and a relatively high shield porosity. The shielded embodiment of the invention helps prevent a loss of acoustic admittance due to fluid grazing past the liner. Another embodiment that is not necessarily cooled, includes the resonator chamber, low porosity face sheet and high porosity shield, but no coolant plenum for bypassing coolant around the resonator chamber. An associated method of retrofitting an acoustic treatment into a fluid handling module includes installing openings in the module and mounting a resonator box 44 on the module so that the inlets to the resonator necks register with the installed openings.

摘要： An augmentor liner is provided that includes an annulus disposed between a first wall and a second wall, and a plurality of baffles. The first wall is disposed radially inside of the second wall. The plurality of baffles extend heightwise between the first wall and the second wall, and are circumferentially spaced apart from one another by a distance. The distance between adjacent baffles is such that an acoustic wave entering an annulus compartment will travel between the first wall and second wall in a direction having a radial component that is substantially greater than a circumferential component. The baffle spacing may alternatively be described as being such that the circumferential component of the acoustic wave is substantially damped and therefore does not materially contribute to undesirable screech.
