Patent number: 12184518Abstract: Methods and systems are provided for inferred information propagation for aircraft prognostics. The method includes receiving, by a processor, an original time-series of data points for a component as an input; preprocessing the input to divide the original time-series of data into subsets of data by applying a time-window over the original time-series of data points; and computing, by the processor, a Mutual Information (MI) value for each pair of variables within each subset of data. The method also includes constructing, by the processor, a sequence of relationship graphs using the computed MI values; clustering, by the processor, each relationship graph; and analyzing, by the processor, the time-ordered sequence of clustered relationship graphs to identify features in the component.Type: GrantFiled: August 7, 2023Date of Patent: December 31, 2024Assignee: The Boeing CompanyInventors: Charles Eugene Martin, Tsai-Ching Lu, Steve Slaughter, Alice A.

Publication number: 20210276688Abstract: A method for making large vehicle body sections, skins, and panels, including three dimensional sections, skins, and panels, using carbon fiber filaments comingled with thermoplastic polymer filaments to form comingled fibers. The first step is the manufacture of a composite preform using the comingled fibers. The comingled fibers are chopped by a fiber chopper unit mounted on a robot arm to create chopped comingled fibers that are sprayed and set on a preform mold to create a comingled fiber preform. The second step is forming the comingled fiber preform into a composite laminate using heat and pressure to consolidate the comingled fibers on a tooling surface. The disclosed method can be used for making large and contoured thermoplastic composite panels, skins, or sections suitable for light aircraft, automobiles, eVTOL's and other panel applications at a high production rate.Type: ApplicationFiled: March 4, 2021Publication date: September 9, 2021Applicant: Galactic Co., LLCInventors: Rob Sjostedt, Steve Slaughter
