  • Laminar flow panel
    Patent number: 10556670
    Abstract: An aerodynamic body operable to both promote laminar flow and satisfy structural requirements is disclosed. A perforated panel skin comprises an inner surface and an outer surface of the aerodynamic body. A micro-lattice support structure is coupled to the inner surface and defines airflow gaps allowing suctioning of air from the outer surface through the perforated panel skin and into a plenum of the aerodynamic body. Rows of main beams of the micro-lattice support structure are aligned along land lines oriented in a substantially chord-wise direction relative to an airflow over the aerodynamic body.
    Type: Grant
    Filed: February 12, 2016
    Date of Patent: February 11, 2020
    Assignee: The Boeing Company
    Inventors: Henry J. Koppelman, Michael K. Klein
  • Laminar flow panel
    Patent number: 10370090
    Abstract: An aerodynamic body operable to both promote laminar flow and satisfy structural requirements is disclosed. A perforated panel skin comprises an inner surface and an outer surface of the aerodynamic body. At least one hollow member is coupled to the inner surface and is operable to suction air from the outer surface and through the perforated panel skin. The at least one hollow member is oriented in a substantially chord-wise direction relative to an airflow over the aerodynamic body.
