Laminar Flow Panel

摘要

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.

1. An aerodynamic body defining a chord-wise direction relative to an airflow over the aerodynamic body, comprising:
an outer panel skin having an inner surface, an outer surface, and a plurality of perforations extending from the inner surface to the outer surface, the outer panel skin extending around an interior surface of the aerodynamic body and defining a leading edge of the aerodynamic body; and a micro-lattice stiffener structure including:
a plurality of main beams each having at least a first end connected to the inner surface of the outer panel skin, anda plurality of diagonal support struts each extending diagonally between and connected to adjacent main beams;wherein the micro-lattice stiffener structure extends along the inner surface of the outer panel skin downstream of the plurality of perforations, and the plurality of main beams and the plurality of diagonal support struts define airflow gaps there between to place the plurality of perforations in fluid communication with the interior surface of the aerodynamic body downstream from the micro-lattice stiffener structure.
