Abstract
Official abstract text for this publication.
A system for controlling aircraft boundary layer airflow comprising a frame structure configured to be coupled or integral to an inner surface of an aircraft nacelle, the frame configured to support to the nacelle, and/or a modular plenum configured to be received by the frame structure, the modular plenum comprising a truncated tetrahedron intersected at its apex by a duct. The frame may comprise a plurality of sub-frames. The system may further comprise a plurality of modular plenums, each configured to fit within a sub-frame. The system may further comprise a flexible material configured to couple a first duct to a second duct. The system may further comprise a nacelle configured to receive the system.
First claim
Opening claim text (preview).
I claim: 1 . A system for controlling aircraft boundary layer airflow comprising: a frame structure configured to be coupled to an inner surface of an aircraft nacelle, the frame configured to support to the nacelle; a modular plenum configured to be received by the frame structure, the modular plenum comprising a truncated tetrahedron intersected at its apex by a duct. 2 . The system of claim 1 , wherein the frame comprises a plurality of sub-frames. 3 . The system of claim 2 , further comprising a plurality of modular plenums, each configured to fit within a sub-frame. 4 . The system of claim 1 , further comprising a flexible material configured to couple a first duct to a second duct. 5 . The system of claim 1 , further comprising a nacelle configured to receive the system. 6 . The system of claim 1 , further comprising a perforated outer surface, wherein air enters the modular plenum through the perforated outer surface. 7 . The system of claim 1 , further comprising a pump that draws air into the modular plenum. 8 . A system for controlling aircraft boundary layer airflow comprising: a frame structure configured to be coupled to an inner surface of an aircraft nacelle, the frame configured to support to the nacelle; a modular plenum comprising configured to be received by the frame structure, the modular plenum comprising a truncated tetrahedron intersected at its apex by a duct. 9 . The system of claim 8 , wherein the frame comprises a plurality of sub-frames. 10 . The system of claim 9 , wherein the modular plenum is configured to fit within a sub- frame. 11 . The system of claim 8 , further comprising a nacelle configured to receive the system. 12 . The system of claim 8 , further comprising a perforated outer surface, wherein air enters the modular plenum through the perforated outer surface. 13 . The system of claim 8 , further comprising a pump that draws air into the modular plenum. 14 . The system of claim 13 , wherein the pump draws air into the modular plenum through a perforated surface formed in an aircraft nacelle. 15 . The system of claim 9 , wherein the frame comprises a plurality of sub-frames configured to provide support to an aircraft nacelle.
