  • Impact resistance acoustic treatment
    Publication number: 20070012508
    Abstract: A liner assembly for a duct includes noise attenuation panel for dissipating sound energy generated within the duct. A damage resistant acoustic panel for installation in high velocity impact prone locations includes a plurality of openings for communicating noise signals to the noise attenuation panel. At lease some of the openings includes a first diameter that extends a depth into the acoustic panel. The depth is no greater than the first diameter. A second portion extends the remainder of the thickness into the acoustic panel and includes a diameter greater than the first diameter. The increased area provided by the second diameter reduces restriction to the transmission of sound energy to the noise attenuation panel within an acoustic panel thickness required for protecting against foreign object damage.

  • Bleed housing
    Publication number: 20050106009
    Abstract: A gas turbine engine compressor has a number of shroud rings, at least a bleed one of which defines a number of bleed ports. A structural hub is downstream of the shroud rings and secured relative to the shroud rings. A structural hub case extends from an aft joint with the structural hub to a fore joint with a joined one of the shroud rings and has a number of valve ports. At least a portion of the structural case extends structurally between the fore and aft joints. A valve element is shiftable between first and second conditions for respectively blocking and not blocking communication through the valve ports.
