Abstract
An engine enclosure for containing a gas turbine engine is provided. An exemplary engine enclosure includes features that improve noise and thermal attenuation, reduce the weight of the enclosure, and provide for more accessible access points to the interior volume of the engine enclosure.
Claims20
An enclosure for containing at least a portion of a gas turbine engine, the enclosure comprising:
- at least one wall defining at least a portion of an interior volume of the enclosure, the wall of the enclosure comprising:
- a first insulation panel;
- a sound absorption member positioned outwardly of the first insulation panel with respect to the interior volume;
- an acoustic barrier positioned adjacent to and outwardly of the sound absorption member with respect to the interior volume;
- an outer shell positioned outwardly of the acoustic barrier with respect to the interior volume, wherein the outer shell is formed as a monolithic unitary composite component from a composite material, the outer shell coupling the at least one wall.
An enclosure for containing at least a portion of a gas turbine engine, the enclosure comprising:
- a plurality of walls defining an interior volume, a monolithic outer shell coupling adjacent walls and forming at least a portion of each of the walls, the monolithic outer shell formed of a composite material, at least one of the walls comprising:
- a first insulation panel;
- a sound absorption member positioned outwardly of the first insulation panel with respect to the interior volume;
- and
- an acoustic barrier positioned adjacent to and outwardly of the sound absorption member with respect to the interior volume;
- wherein the outer shell is positioned outwardly of the acoustic barrier with respect to the interior volume.
An enclosure for containing at least a portion of a gas turbine engine, the enclosure comprising:
- at least one wall defining at least a portion of an interior volume of the enclosure, the wall of the enclosure comprising:
- a first insulation panel;
- an acoustic panel positioned outwardly of the first insulation panel with respect to the interior volume, the first acoustic panel comprising a sound absorption member and an acoustic barrier;
- an outer shell formed of a composite material and positioned outwardly of the acoustic panel with respect to the interior volume;
- and
- a hat stiffener, comprising:
- a hat member defining a stiffener volume, the hat member comprising a first flange attached to the outer shell, a hat portion extending inwardly from the outer shell, and a second flange attached to the outer shell;
- and
- a foam member disposed within the stiffener volume.
