Abstract
An assembly is provided for active laminar flow control. This assembly includes a panel, which panel includes an outer skin, an inner skin and a plurality of plenums between the outer skin and the inner skin. Each of the plurality of plenums is fluidly coupled with a respective array of perforations through the outer skin. The panel is constructed from fiber-reinforced composite material.
Claims17
An assembly for active laminar flow control, comprising:
- a panel comprising an outer skin, an inner skin, a core section and a plurality of plenums;
- the core section extending between and connected to the outer skin and the inner skin, and the core section comprising a first sidewall;
- the plurality of plenums between the outer skin and the inner skin, each of the plurality of plenums fluidly coupled with a respective array of perforations through the outer skin, and a laterally adjacent pair of the plurality of plenums laterally separated by and partially formed by the first sidewall;
- and
- the panel constructed from fiber-reinforced composite material;
- wherein the core section further comprises a plurality of corrugations arranged between the outer skin and the inner skin;
- wherein a first of the plurality of corrugations comprises a bridge, the first sidewall, a second sidewall, a first flange and a second flange;
- and
- wherein a first perforation in the respective array of perforations extends through the outer skin and the first flange.
