Patent number: 11110647Abstract: Systems and processes that integrate thermoplastic and shape memory alloy materials to form an adaptive composite structure capable of changing its shape. For example, the adaptive composite structure may be designed to serve as a multifunctional adaptive wing flight control surface. Other applications for such adaptive composite structures include in variable area fan nozzles, winglets, fairings, elevators, rudders, or other aircraft components having an aerodynamic surface whose shape is preferably controllable. The material systems can be integrated by means of overbraiding (interwoven) with tows of both thermoplastic and shape memory alloy materials or separate layers of each material can be consolidated (e.g., using induction heating) to make a flight control surface that does not require separate actuation.Type: GrantFiled: April 26, 2018Date of Patent: September 7, 2021Assignee: The Boeing CompanyInventors: Jeffery L.

Patent number: 10983078Abstract: A computer-implemented method of determining moisture content of a composite structure is provided. The method includes performing a thermal analysis calculation on the composite structure to determine a temporal surface temperature profile of the composite structure based on temporal environmental parameter profiles, wherein the surface temperature profile is determined independently of a moisture content of the composite structure. The method also includes performing a moisture content analysis calculation on the composite structure to determine a moisture content of the composite structure, wherein the moisture content analysis calculation is based on the determined temporal surface temperature profile and a thickness of the composite structure. The thermal analysis calculation is performed iteratively with a first time period and the moisture content analysis calculation is performed iteratively with a second time period that is longer than the first time period.Type: GrantFiled: November 22, 2019Date of Patent: April 20, 2021Assignee: The Boeing CompanyInventors: Sahrudine Apdalhaliem, Heh-Chyun Cliff Chen, Waeil M.

Patent number: 10876922Abstract: Methods and systems for determining optical properties for light transmitted mediums are provided. One method includes acquiring one or more measured values indicative of a reflectance for a material, acquiring one or more measured values indicative of a transmittance for the material, and determining a set of calculated values for an index of refraction coefficient and an extinction coefficient from the one or more measured values indicative of reflectance and transmittance, respectively. The method includes identifying a calculated value from the set of calculated values for the index of refraction coefficient and a calculated value from the set of calculated values for the extinction coefficient that are within a threshold determined by the difference between the one or more measured values indicative of the reflectance or transmittance and a predicted reflectance or transmittance, respectively. The method includes determining a reflectance and transmittance for the material using the calculated values.Type: GrantFiled: June 11, 2014Date of Patent: December 29, 2020Assignee: The Boeing CompanyInventors: Sahrudine Apdalhaliem, Kimberly D.

Patent number: 10774858Abstract: Provided are assemblies having composite structures interlocked with shape memory alloy structures and methods of fabricating such assemblies. Interlocking may involve inserting an interlocking protrusion of a shape memory alloy structure into an interlocking opening of a composite structure and heating at least this protrusion of the shape memory alloy structure to activate the alloy and change the shape of the protrusion. This shape change engages the protrusion in the opening such that the protrusion cannot be removed from the opening. The shape memory alloy structure may be specifically trained prior to forming an assembly using a combination of thermal cycling and deformation to achieve specific pre-activation and post-activation shapes. The pre-activation shape allows inserting the interlocking protrusion into the opening, while the post-activation shape engages the interlocking protrusion within the opening. As such, activation of the shape memory alloy interlocks the two structures.Type: GrantFiled: June 22, 2017Date of Patent: September 15, 2020Assignee: The Boeing CompanyInventors: Waeil M.
