Patent number: 11267556Abstract: A method of using a split winglet includes providing an aircraft having a winglet attach fitting attaching a split winglet to a wing. The split winglet has an upper winglet and a lower winglet. The method additionally includes maintaining the winglet attach fitting and winglet at a first height relative to a fuselage when the aircraft is non-flying, and moving the winglet attach fitting and winglet to a second height relative to the fuselage when the aircraft is flying, the second height being higher than the first height.Type: GrantFiled: February 8, 2019Date of Patent: March 8, 2022Assignee: The Boeing CompanyInventors: Philipp Witte, Darrell D. Campbell, Jr., Billy P. Tung, Fedor Kleshchev

Patent number: 10836472Abstract: A manufacture and process for a winglet formed as a unitary structure by laying up and co-curing three ply-sets in a bifurcated configuration, without metal and fasteners, comprising three continuous surfaces: a first ply-set comprising a first continuous surface forming: an outboard surface of an upper blade; an outboard portion of a root region; and an outboard surface of a lower blade; a second ply-set forming a second continuous surface forming an inboard surface of the upper blade and an upper skin of the root region; and a third ply-set forming a third continuous surface forming an inboard surface of the lower blade and a lower skin of the root region . . . continuous surface. The root region being integral in the bifurcated configuration, matching a shape of an airfoil of a tip of a wing, and comprising two supports that comprise an additional ply-set shaped to receive an attachment system.Type: GrantFiled: November 6, 2016Date of Patent: November 17, 2020Assignee: The Boeing CompanyInventors: Philipp Witte, Stanley Warren Stawski, Fedor A. Kleshchev, Joshua William Zarfos, Parth R. Naidu

Patent number: 10118321Abstract: A tooling apparatus for manufacturing a composite structure may include a rigid outer tool for receiving a composite layup, a tubular inner vacuum bag in contact with the composite layup and defining an inner vacuum chamber, and an outer vacuum bag covering at least a portion of the rigid outer tool. The outer vacuum bag and the tubular inner vacuum bag may collectively define an outer vacuum chamber containing the composite layup. An outer bag vacuum source may be fluidly coupled to the outer vacuum bag for applying an outer bag vacuum pressure on the outer vacuum chamber. An inner bag vacuum source may be fluidly coupled to the tubular inner vacuum bag for applying an inner bag vacuum pressure on the inner vacuum chamber during application of the outer bag vacuum pressure on the outer vacuum chamber.Type: GrantFiled: January 5, 2016Date of Patent: November 6, 2018Assignee: The Boeing CompanyInventors: Philipp Witte, Stanley W. Stawski, Fedor A. Kleshchev, Joshua Zarfos, Parth Naidu

Patent number: 9738375Abstract: A method and apparatus for forming a winglet formed as a one-piece composite for an aircraft is presented. The winglet comprises a first blade, a second blade, and a root region. The first blade includes a first leading edge and a first trailing edge. The second blade includes a second leading edge and a second trailing edge. The second blade is positioned at an angle to the first blade. The root region is co-cured with the first blade and the second blade to form the winglet. The root region is configured to receive an attachment system for attaching the winglet to a wing of the aircraft.Type: GrantFiled: December 5, 2013Date of Patent: August 22, 2017Assignee: THE BOEING COMPANYInventors: Philipp Witte, Stanley Warren Stawski, Fedor A. Kleshchev, Joshua William Zarfos, Parth R. Naidu
