Abstract: Motion-damping systems and methods that include motion-damping systems are disclosed herein. The motion-damping systems include a flexible body that is configured to extend within a gap that is defined between a base structure and an attached component. The motion-damping systems further include a magnetic assembly and a ferromagnetic body. One of the magnetic assembly and the ferromagnetic body is located within the flexible body and the other of the magnetic assembly and the ferromagnetic body is operatively affixed to a selected one of the base structure and the attached component. The magnetic assembly and the ferromagnetic body are oriented such that a magnetic force therebetween retains the flexible body in physical contact with the selected one of the base structure and the attached component. The methods include methods of installing and/or operating the motion-dampening systems.

Abstract: Methods and systems for duct protection of a vehicle are provided. The methods and systems provided include an apparatus for containing a flow of fluid discharged from a fracture in a duct. The apparatus includes a ballistic containment layer and an insulation sheath coupled to the ballistic containment layer. The insulation sheath includes a first air containment layer, an insulation layer, and a second air containment layer.

Abstract: A method and apparatus for reworking a structure. A compaction blanket comprising a number of magnets is placed on the structure. A heat source is applied on the compaction blanket, wherein the compaction blanket is between the heat source and a rework of the structure and heat is conducted from the heat source through the compaction blanket to heat the rework.

Abstract: Motion-damping systems and methods that include motion-damping systems are disclosed herein. The motion-damping systems are configured to damp relative motion between a base structure and an attached component that define a gap therebetween. The systems include an at least substantially rigid tubular structure that defines an internal volume and extends within the gap. The systems also include a magnetic assembly and a magnetically active body. One of the magnetic assembly and the magnetically active body is located within the tubular structure and the other of the magnetic assembly and the magnetically active body is operatively attached to a selected one of the base structure and the attached component. The magnetic assembly is in magnetic communication with the magnetically active body such that a magnetic interaction therebetween resists motion of the attached component relative to the base structure. The methods include dissipating energy with the motion-damping system.

Abstract: A method and apparatus for an electromagnetic acoustic transducer. An apparatus comprises a conductive material and a current inducer. The conductive material is configured to generate a magnetic field, wherein the magnetic field has magnetic flux lines that are substantially fixed and the conductive material has a temperature that is equal to or less than a critical temperature at which the conductive material has substantially zero electrical resistance. The current inducer is configured to cause an electric current to flow in a test object that interacts with the magnetic field, wherein the electric current has a frequency that generates an acoustic wave in the test object.

The body defines a cavity therethrough. The particle trap also includes first and second HTS end plates or first and second electrodes positioned at opposite ends of the cavity. At least one of the end plates or at least one of the electrodes defines at least one opening into the cavity to permit charged particles to enter and exit the cavity.

Abstract: There is provided an apparatus and method for making a glass preform with nanofiber reinforcement. The apparatus comprises a container for melting one or more glass components in a mixture comprising the glass components and one or more nanofibers. The container has an opening that allows escape of any gas released from the glass components when the glass components are melted in the container. The apparatus further comprises one or more heating elements for heating the container. The apparatus further comprises one or more electric field devices, positioned exterior to the glass components, that create an electric field in a volume of the mixture in order to orient the nanofibers within the glass components when the glass components are melted in the container.
