  • Systems and methods for forming perforations in a barrel structure
    Patent number: 11059106
    Abstract: A drilling system includes a single robotic drilling unit having a drill end effector positioned inside a barrel section configured as a composite sandwich structure having an inner face sheet. The robotic drilling unit is operable to drill a plurality of perforations into the inner face sheet using the drill end effector. The robotic drilling unit is configured to index a hole pattern of the perforations to one or more cell walls of a honeycomb core of the composite sandwich structure. The robotic drilling unit is configured to form the hole pattern in the inner face sheet such that the perforations are located at a spaced distance from the cell walls of the honeycomb core.
    Type: Grant

  • System for forming perforations in a barrel section
    Patent number: 9884370
    Abstract: A drilling system may include a plurality of robotic drilling units. Each one of the robotic drilling units may include a drill end effector positioned inside a barrel section. The barrel section may be configured as a composite sandwich structure having an inner face sheet. The robotic drilling units maybe operable in synchronized movement with one another to drill a plurality of perforations into the inner face sheet using the drill end effectors in a manner providing a predetermined percent-open-area of the inner face sheet.

  • Vacuum assisted ply placement shoe and method
    Patent number: 7213629
    Abstract: A device for placing a ply on a substrate surface includes a vacuum manifold assembly configured for attachment to a vacuum source and a substrate seal configured to provide a substantially gas impermeable interface with the substrate surface. This device further includes a ply seal configured to provide a substantially gas impermeable interface with the ply. In this manner, vacuum applied to the vacuum manifold assembly depressurizes an area between the ply and the substrate surface.
