  • 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.

  • 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.

  • Machine assisted laminator and method
    Patent number: 7824512
    Abstract: A method of fabricating a composite part comprises generating a partial vacuum between a ply material and a form, advancing the partial vacuum and the ply material along the form, sensing an edge of a previously applied course of the ply material and cutting a profile on the ply material in response to the sensed edge.
