  • Thermal-acoustic sections for an aircraft
    Patent number: 9038774
    Abstract: Embodiments of thermal-acoustic sections for an aircraft for reducing noise along an acoustic path produced from an acoustic source are provided herein. The thermal-acoustic section comprises a first porous layer having a first characteristic acoustic impedance. A second porous layer is disposed adjacent to the first porous layer and has a second characteristic acoustic impedance that is greater than the first characteristic acoustic impedance. The thermal-acoustic section is configured to be positioned along the acoustic path such that at least a portion of the noise from the acoustic source is directed through the first porous layer to the second porous layer to promote absorption of the noise.
    Type: Grant

  • Flat-Cured Composite Structure
    Publication number: 20100043955
    Abstract: An embodiment of the invention includes a composite structure fabricated from at least one pre-cured flat face sheet applied to a core with an adhesive. Once the pre-cured flat face sheet is applied to the core, curing of the adhesive may take place to bond the pre-cured flat face sheet to the core. Before the bonding of the pre-cured flat face sheet to the core takes place, the pre-cured flat face sheet may be prepared by separately curing a composite face sheet.
