Patent number: 11767770Abstract: A system and method for mitigating thermal loading between engine exhaust structures having different coefficients of thermal expansion. The engine exhaust structure comprises a metallic duct portion, a ceramic duct portion, and a double bipod fitting joining the metallic duct portion to the ceramic duct portion. The double bipod fitting is capable of flexing and taking up the thermal expansion differences between the joined metallic and ceramic ducts across the full temperature spectrum that an engine exhaust structure will experience in service.Type: GrantFiled: August 10, 2021Date of Patent: September 26, 2023Assignee: The Boeing CompanyInventors: Michael D. Nevinsky, David T. Misciagna, Joseph Orso, Robert A. DiChiara, Jr, Marc Daniel Spiccia Karasek

Publication number: 20220380117Abstract: A bladder. The bladder includes a bladder wall include first dimensions. The bladder also includes a first port disposed in the bladder wall. The bladder also includes knitted seams stitched into a first pattern in the bladder wall. The first pattern is configured such that when the bladder wall is subjected to a compressive force, the bladder collapses into a first pre-determined shape that has second dimensions less than the first dimensions.Type: ApplicationFiled: February 15, 2022Publication date: December 1, 2022Applicant: The Boeing CompanyInventors: Michael D.

Publication number: 20140079906Abstract: An assembly and method for manufacturing a composite reinforcement for unitizing a structure are provided. According to one embodiment, the assembly includes a base having a plurality of pins extending outwardly therefrom to define a structure about which a composite fiber is wound to define a composite reinforcement preform. The assembly also includes a plurality of mandrels positioned adjacent to the base and at least a portion of the composite reinforcement preform, and a cap that is positioned over at least a portion of the plurality of mandrels. The cap is configured to engage each of the mandrels to support the mandrels and the composite reinforcement preform during a curing process to form the composite reinforcement.Type: ApplicationFiled: April 22, 2013Publication date: March 20, 2014Applicant: The Boeing CompanyInventors: David T.

Patent number: 6863980Abstract: A ceramic fabric and a resin are combined to form a fire protection sheet capable of being co-cured onto a parent laminate structure. The resulting monolithic composite firewall shows fire protection ability comparable to that of the conventional titanium structure, without the problems associated therewith, such as titanium panel separation and disbonding. The fire protection sheet easily conforms to the shape of the parent laminate and is also useful as a repair material for damaged conventionally protected firewalls.Type: GrantFiled: October 8, 2002Date of Patent: March 8, 2005Assignee: The Boeing CompanyInventors: David T. Misciagna, Dennis J. Landi, Philip G. Persaud
