Patent number: 11565460Abstract: Provided are systems and apparatuses for manufacturing aircraft support structures. An example robotic end effector comprises a rotatable reel with a flat strip of material wound around the reel. The end effector further includes a forming shoe including a forming surface contacting the strip of material. A first end of the forming surface corresponds to a start shape and a second end of the forming surface corresponds to an end shape. As the strip of material passes from the first end of the forming surface to the second end of the forming surface, the strip of material transitions from the first shape to the end shape and is deposited as a formed stringer ply onto an application surface. The forming shoe may further include a vacuum system to suction air through a plurality of ports along the forming surface to urge the strip of material against the forming surface.Type: GrantFiled: February 26, 2021Date of Patent: January 31, 2023Assignee: The Boeing CompanyInventors: Jerry D. Chungbin, Narumi Watanabe

Publication number: 20220405438Abstract: A method implemented by a computing system that facilitates formation of an object from a material comprises receiving an object model that specifies a top surface and a side surface connected to an edge of the top surface via a fillet that extends along the edge. At a particular region along the edge, adjacent planar regions of the side surface define an obtuse angle therebetween. The fillet is adjusted along the edge to have a first radius at a particular distance from the particular region and to have a second radius, smaller than the first radius, proximate the particular region. Output data associated with an adjusted model is communicated to equipment configured to form a mandrel that facilitates formation of the object. Adjusting the fillet to have a smaller radius proximate the particular region facilitates elimination of wrinkles in the material when draped over the mandrel to form the object.Type: ApplicationFiled: April 14, 2022Publication date: December 22, 2022Inventors: Troy Winfree, Eric S. Kamila, Noah J. Stockwell, William J. Moon, Jerry D. Chungbin

Publication number: 20220292233Abstract: A method performed by a computing system that facilitates formation of an object comprises receiving manufacturing process data associated with an object to be formed via a drape-forming operation. The computing system receives a parametric model of the object. The parametric model facilitates specification of a radius of a fillet within a region associated with the object. The computing system determines, based on the parametric model of the object, a unit vector field associated with a surface of the object and the manufacturing process data. The computing system adjusts the radius of the fillet of the parametric model within the region to reduce an average divergence of the vector field to a minimum amount, and communicates output data associated with an adjusted parametric model to equipment configured to form a mandrel that facilitates formation of the object.Type: ApplicationFiled: January 4, 2022Publication date: September 15, 2022Inventors: Troy Winfree, Eric S. Kamila, William J. Moon, Jerry D. Chungbin

Patent number: 10442153Abstract: Provided are stiffened stringer panels with integrated indexing stacks. An example composite panel comprises a skin member having an inner surface. An index for positioning a support tool comprises a first set and second set of layered laminate stacks coupled to the inner surface such that a channel is formed between the first and second set of layered laminate stacks. The first and second set of layered laminate stacks is configured to cradle a support tool in the channel to automatically align the support tool relative to the panel. A stringer may include a cap portion that extends from the first set to the second set of layered laminate stacks to form flange portions on the inner surface of the skin member. The index and the skin member may be co-cured or co-bonded.Type: GrantFiled: December 22, 2017Date of Patent: October 15, 2019Assignee: The Boeing CompanyInventors: John M. Shinozaki, Patrick B.
