    摘要: A method for manufacturing a composite part is provided. A polymer materials formed into a shape whose outer surface has a desired part configuration. A base coating is applied to substantially all of the outer surface leaving at least one access to the polymer material. The base coating includes a selected metal existing as a constituent thereof. The same selected metal is then sprayed in atomized form on the base coating covered outer surface. The selected metal in atomized form molecularly bonds only to the selected metal existing as a constituent of the base coating. The polymer material is then contacted with a polymer solvent by means of the access. The polymer solvent molecularly breaks down the polymer material such that it exits the access. As a result, the selected metal in atomized form bonded with the selected metal existing as a constituent of the base coating forms a metallic shell substantially void of the polymer material. Fill material selected design performance characteristics is introduced into the metallic shell thereby forming the composite part.

    摘要: A system for monitoring a structure is built on a printed circuit board (PCB) mounted at the surface of the structure. A piece of single crystal silicon is mounted on the PCB and is in contact with the structure. An infrared source directly illuminates the silicon while an infrared detector is focused thereon to monitor isochromatic fringe patterns projected from the silicon as a direct indication of stress at the surface. One or more other sensors are coupled to the PCB for collecting data indicative of other physical conditions experienced by the structure. A wireless system communicates with each such sensor so that the data so collected can be received at a remote location.

    摘要: An articulated control surface for flight control utilizes a moldable conl surface that is shaped by contracting and elongating shape memory alloys embedded within the control surface. The shape memory alloys contract when heated via an applied electric current and elongate when cooled, i.e., the electric current is removed. The resulting control surface is capable of generating a curved control surface without any electro/mechanical or hydraulic control systems.

    摘要: Electromagnets are disposed in an elastomeric coating affixed to a body esed to a fluid. Controllable magnetic forces created by the electromagnets produce a wavy-wall configuration in the surface of the coating which may be static, dynamic, or static in part and dynamic in part, and which interfaces with the fluid to controllably alter noise, turbulence and drag characteristics of the body mechanically. Electrodes may be fixed on the surface of the coating to produce electric force fields for interacting with the magnetic fields and the wavy-wall, to produce magnetohydrodynamically generated Lorentz forces which controllably further alter noise, turbulence and drag characteristics of the body.

    摘要: Apparatus and process for providing a communication link between separate submersibles and, in particularly, for providing communication between a launched submersible and a host submersible. A thread of polyelectrolytic material is provided in electrical communication with a launched submersible prior to launch and payed out and stretched as the launched submersible extends a distance from the host submersible to permit secure communication between the submersible, transmission of command signals for guidance and arming/disarming, from the host to the launched submersible, and to receive data from deployed sensors. The conductive thread includes an organic solvent having dispersed therein a first polymer consisting of a water insoluble polymer that serves as the conductive polymer backbone and a second polymer consisting of a semi-water soluble high molecular weight polymer that effectively surrounds the conductive polymer backbone. The polymer components may be made from monomers on board the host submersible, if desired. When the communication link is no longer needed, self destruction by command or time actuated, leaving very little residual pollutants or evidence of the communication link, or any other indication of electronic information transmission.
