Patent number: 7744040Abstract: Aircraft trailing edge devices, including devices with non-parallel motion paths, and associated methods are disclosed. A device in accordance with one embodiment includes a wing and an inboard trailing edge device coupled to the wing and movable relative to the wing between a first stowed position and a first deployed position along a first motion path. An outboard trailing edge device can be coupled to the wing outboard of the inboard trailing edge device, and can be movable relative to the wing along a second motion path that is non-parallel to the first motion path. An intermediate trailing edge device can be coupled between the inboard and outboard trailing edge devices and can be movable along a third motion path that is non-parallel to both the first and second motion paths. Each of the trailing edge devices can open a gap relative to the wing when moved to their respective deployed positions.Type: GrantFiled: November 4, 2008Date of Patent: June 29, 2010Assignee: The Boeing CompanyInventors: Douglas S. Lacy, Kevin W. Beyer, Stephen T. Brown, Paul W. Dees, Neal V. Huynh, Jan A. Kordel, Clayton A. Prow, Seiya Sakurai

Patent number: 7258308Abstract: A method and apparatus for controlling airflow with a gapped trailing edge device having a flexible flow surface. The airfoil can include a first portion having a first leading edge, a first flow surface, and a second flow surface facing opposite from the first flow surface. The airfoil can further include a second portion having a second leading edge and a trailing edge, with at least part of the second portion being positioned aft of the first portion. The second portion is moveable relative to the first portion between a first position and a second position, with the second leading edge separated from at least part of the first portion by an airflow gap when the second portion is in the second position. The second portion includes a flexible flow surface that has a first shape when the second portion is in the first position, and has a second shape different than the first shape when the second portion is in the second position.Type: GrantFiled: July 2, 2002Date of Patent: August 21, 2007Assignee: The Boeing CompanyInventors: Kevin W. Beyer, Stephen J. Fox, Douglas S. Lacy, Paul T. Meredith, Clayton A. Prow, Seiya Sakurai, Stephen L. Wells

Patent number: 7243881Abstract: Trailing edge devices configured to carry out multiple functions, and associated methods of use and manufacture are disclosed. An external fluid flow body (e.g., an airfoil) configured in accordance with an embodiment of the invention includes a first portion and a second portion, at least a part of the second portion being positioned aft of the first portion, with the second portion being movable relative to the first portion between a neutral position, a plurality of upward positions, and a plurality of downward positions. A guide structure can be coupled between the first and second portions, and an actuator can be operatively coupled between the first and second portions to move the second portion relative to the first portion. In one embodiment, a flexible surface can track the motion of the second portion and can expose a gap at some positions.Type: GrantFiled: June 3, 2004Date of Patent: July 17, 2007Assignee: The Boeing CompanyInventors: Seiya Sakurai, Stephen J.

Patent number: 6601801Abstract: An airfoil assembly, such as a wing or horizontal stabilizer, has a gapped trailing-edge control surface and a door connected to the control surface by a linkage such that deflection of the control surface in one direction causes the door to pivot, thus opening an air flow slot for air to flow through. The air flow slot begins to open immediately with deflection of the control surface from its nominal position, thus establishing a desirable level of air flow to suppress separation on the control surface. The linkage connecting the control surface to the door is free of rolling or sliding elements, consisting exclusively of members pivotally connected to one another.Type: GrantFiled: April 24, 2002Date of Patent: August 5, 2003Assignee: The Boeing CompanyInventors: Clayton A.
