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. Marcoe, Sahrudine Apdalhaliem, Moushumi Shome

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. Ashmawi, Jaime C. Garcia, Sahrudine Apdalhaliem, Jeffery L. Marcoe, Moushumi Shome

Patent number: 10265923Abstract: Manufacturing a thermoplastic composite tubular structure embedded with a first load fitting comprising the steps of braiding a first plurality of inner layers of thermoplastic composite material around a soluble, expandable mandrel. A first load fitting is positioned on the first plurality of inner layers of thermoplastic composite material. A second plurality of outer layers of thermoplastic composite material is braided around the first load fitting and the mandrel so as to form an overbraided mandrel embedded with the first load fitting. The overbraided mandrel is installed into a matched tooling assembly and heated at a specified heating profile in order to consolidate the first plurality of inner layers of thermoplastic composite material and the second plurality of outer layers of thermoplastic composite material with the first load fitting so as to form a thermoplastic composite tubular structure embedded with the first load fitting.Type: GrantFiled: March 21, 2017Date of Patent: April 23, 2019Assignee: The Boeing CompanyInventors: Jeffery Lee Marcoe, Marc Rollo Matsen, Waeil M.

Patent number: 10202939Abstract: A shape memory alloy (SMA) actuated aerostructure operable to dynamically change shape according to flight conditions is disclosed. Deformable structures are actuated by SMA actuators that are coupled to face sheets of the deformable structures. Actuating the SMA actuators produces complex shape changes of the deformable structures by activating shape changes of the SMA actuators. The SMA actuators are actuated via an active or passive temperature change based on operating conditions. The SMA actuated aerostructure can be used for morphable nozzles such as a variable area fan nozzle and/or a variable geometry chevron of a jet engine to reduce engine noise during takeoff without degrading fuel burn during cruise.Type: GrantFiled: April 3, 2013Date of Patent: February 12, 2019Assignee: The Boeing CompanyInventors: Richard D. Widdle, Matthew T. Grimshaw, Kava S. Crosson-Eltruan, James Henry Mabe, Frederick T. Calkins, Lynn Marie Gravatt, Moushumi Shome

Patent number: 10107269Abstract: An actuator includes a shape-memory alloy (SMA), a power supply that transmits electrical current, a heat source positioned proximate to the SMA, a heat sink positioned proximate to the SMA, and a control module. The control module causes the power supply to transmit the electrical current to the heat source in response to receiving a first signal, thereby causing the heat source to heat the SMA via induction heating. The control module also causes the power supply to cease transmitting the electrical current to the heat source in response to receiving a second signal, thereby causing the heat source to stop heating the SMA. The control module also causes the power supply to transmit the electrical current to the heat sink in response to receiving the second signal, thereby causing the heat sink to cool the SMA via magneto-thermal convection cooling.Type: GrantFiled: January 26, 2016Date of Patent: October 23, 2018Assignee: THE BOEING COMPANYInventor: Moushumi Shome

Patent number: 9664183Abstract: Aspects of the present disclosure generally relate to an SMA actuator that includes a cooling device disposed within a torque tube. In one aspect, the cooling device includes a sliding sleeve, an expandable sleeve, and plurality of cooling fins coupled to the expandable sleeve. Axial movement of the sliding sleeve relative to the expandable sleeve facilitates radial expansion of the expandable sleeve and urges the cooling fins into contact with the torque tube. The cooling fins function as heat sinks when in contact with the torque tube to facilitate the removal of heat from the torque tube to increase the cooling rate of the torque tube. During heating of the torque tube, the cooling fins may be spaced apart from the torque tube to reduce the thermal mass that is heated, thus increasing the heating rate of the torque tube.Type: GrantFiled: January 9, 2015Date of Patent: May 30, 2017Assignee: THE BOEING COMPANYInventors: Sahrudine Apdalhaliem, Moushumi Shome, Kimberly D.
