Patent number: 11305332Abstract: Forging dies are formed from a plurality of layers stacked together to form an assembly, or laminate. Each respective layer may be cut to form a portion of a die cavity, and the layers may be stacked together such that the cut portions are aligned to form the die cavity. The layers are fastened together to form a first die half and/or a second die half of disclosed forging dies. Each layer may be selectively removable from the die half for maintenance and/or replacement. Disclosed forging dies may be formed of lower grade materials as compared to conventional forging dies, and the number and thickness of layers may be varied to accommodate the specific part geometry of the part being forged. Related methods of making said forging dies and using said forging dies to make parts are also disclosed.Type: GrantFiled: January 22, 2021Date of Patent: April 19, 2022Assignee: The Boeing CompanyInventors: David P.

Patent number: 10479474Abstract: Provided are wingtip torque boxes and methods of fabricating such boxes using friction stir welding. Specifically, a wingtip torque box may be formed by friction stir welding two monolithic clamshells along their respective spars thereby forming a new monolithic structure. Use of the friction stir welding and monolithic clamshells simplifies the overall fabrication process and yields a robust wingtip torque box that can be bolted on or otherwise attached to an aircraft wing. The wingtip torque box may include internal grid stiffeners and/or external stiffeners that may be also monolithic with other components of the box. For example, the stiffeners may be machined in spars or skin portions of the clamshells during fabrication of clamshells. The wingtip torque box may have a continuous cavity extending between the ends and, in some embodiments, between spars of the box and providing access for performing various operations inside the box.Type: GrantFiled: July 14, 2016Date of Patent: November 19, 2019Assignee: The Boeing CompanyInventors: Michael P.
