This innovation can transition to current and future manned and unmanned air platforms, as well as future missile defense platforms. Grihon, and A. The technology allows for the creation of complex components that cannot be achieved using traditional subtractive methods such as machining. The performer must be able to print a dielectric polymer, ceramic, etc. These traces must include both electronic capability and RF capability such as ground-signal-ground GSG waveguide or stripline over embedded ground plane and radiating elements antennas.

The definition of embedded here is the integration of conductive surfaces on and within the additively manufactured dielectric structure. Barriers to this development include, but are not limited to, the capability to print cylinders with materials having low-loss good dielectric properties, multi-material print capability, the ability to stop the additive manufacturing process of non-conductive layers, integrate conductive layers such as ink , re-register if necessary , ensure layer cohesiveness, and complete the additive manufacturing process and meet general electronic and RF capabilities low loss performance.

Proposals must apply direct write technology within and inside the cylindrical object. The cylindrical diameter requirement is less than six inches. The cylinder must be created using materials with good dielectric properties, with low RF losses similar to that of Ultem. At least two 2 electrically functional or RF functional layers are required with a goal of 12 layers including interconnects and vias. An RF simulation package, capable of modeling structures at frequencies up to Ka-band, shall be used to generate data on losses, conductivity and resistivity of the resulting RF designs.

In addition, the offeror shall expand the research and development to rugged prototypes of printed structures that can withstand environmental concerns including humidity, dust, shock, vibration, and thermal fluctuations such as that of a missile launch and relevant lifetime. Structures are to be printed inside, within the walls and on the outside of the cylindrical surface and stressed to show the effects of environment upon conductivity, capacitance, s-parameters RF , and product longevity. Full evaluation of resulting prints before and after stresses must be conducted.

Prototypes are to be dissected and examined using scanning electron microscope or similar technology to show structures before and after applied stresses. RF simulations of all designs are required. All results are to be fully documented, and before and after prototypes of environmental evaluations are to be supplied to CCDC Aviation and Missile Center.

The goal would be a single piece, integrated, conformal array after multiple printing steps with power dividing structures on the inside of the cylinder connecting individual radiating elements. Phase shifters allowing steering of the beam shall be integrated on the interior wall using pick-and-place technology.

If the final design requires power amplification to overcome losses of printed structures to allow the design to be evaluated, these components should also be integrated on the interior wall. Phase 3 dual use applications: Particular military applications include generic radar sensor system applications for use on missile technologies that can be applied to hypersonic missile fight environments.

Commercial applications include satellite sensor system applications and also design space specific antenna capability. Transitions of opportunity include both immediate and local capability generation of additively manufactured designs with electronics embedded along with field replacement of sub-system components at the connector level and above i.

The most likely path to transition the cylindrical technology is for a CCDC missile program such as Long Range Maneuverable Fires to adapt the technology during their development and test cycle. These programs run through Wicker, "Integrating stereolithography a. The direct application of this power supply would be for use in driving very compact directed energy devices. The restrictions on size suggest a total geometry volume of about 25 cubic inches.

Therefore, the Army is seeking power supply designs appropriate for several classes of directed energy munitions. While multi-use power supplies are desirable, a single-shot power supply design will satisfy all requirements of this solicitation. The design must show the properties of 1 compact geometry and 2 prime power capability.

The modeling must demonstrate 1 demonstrate how the power supply functions, 2 provide a reasonable expectation to achieve the output needed, and 3 show whether the power supply can be scaled for higher energy outputs, if needed. The fabrication of the first prototype is desirable. The ability to demonstrate proposed performance likely entails a dynamic testing capability for the proposer.

Army applications include prime power for advanced munitions, advanced laser power supplies, multi-mode high-power microwaves, compact radar technologies, and, more generally, directed energy munitions for lower G environments. Thus, the authors must indicate how they intend to interact with these entities to move the development toward commercialization. Commercially this work can support portable lightning simulation, expendable X-ray sources, field medical instrumentation, and oil and mineral exploration.

The IBA uses optical switching to excite and amplify an array high power pulses which provides neutralization capability at standoff. In the recent years, laser diode has shown to have great potentials as light sources in the commercial applications. This holds the special interest with providing a cost effective commercial based solutions for triggering PCSS without the use of an external laser, making a more compact, reliable, and cost effective solution possible. Assess LDA drive power source requirements.

Demonstrate the capability to achieve conduction pulse width of greater than 20 ns and a timing jitter of less than 0.

Establish fabrication and production processes to scale the prototype system to trigger enough current sharing filaments to switch in excess of 10 kA with 8 PCSSs connected in parallel at the above hold-off voltage, pulse width, jitter. Military applications will include various fast switch-based microwave sources for directed energy systems, UWB Ultra-Wideband pulse sources and ground penetration radar.

Commercial applications includes X ray generation and medical devices. Its goal will bring novel approach to more compact, reliable, and cost effective high voltage switching mechanism to military and commercial applications. Digest of Technical Papers. Zutavern, A. Mar, M.

Helgeson, D. Brown, H. Hjalmarson, and A. Zutavern, Steven F. Glover, Kim W. Reed, Michael J. Cich, A. Lithium-ion batteries LIBs have been the dominant solution for the portable energy needs of myriad military and commercial applications.

The performance of LIBs in terms of high energy and power density is unparalleled. The development of alternative chemistries has not advanced to any significant degree.

Notwithstanding the performance advantage LIBs hold over competing technologies, significant improvements to battery footprint, energy and power density, and cost can be achieved through technical improvements to electrodes that impart higher rate capability, higher charge capacity, and, in the case of cathodes, sufficiently high voltage. In this regard, new advances in materials need to be leveraged to usher in the next generation of the LIBs. Borrowing complex hierarchical structures found in nature, a superior approach might incorporate the use of hierarchical materials as the basis for the design of new electrodes, collectors, and separators in LIBs.

This topic endeavors to develop the fundamentals of such a hierarchical structure design for improved electrochemical performance of LIBs. The methodology should be guided by physico-electro-chemical, thermodynamic, and kinetic principles for optimizing the structures. Multidimensional porous structures of electrodes to facilitate rapid ion and electron transport pathways and short solid state diffusion lengths will be investigated. Design of porosity will be directed by accessibility of solvated ions in the electrolyte without compromising the tap density of electrodes. LIBs with prototype hierarchical electrodes will be fabricated and evaluated to verify the design approach and identify the optimization parameters and methods for practical implementation in Phase II.

Material compatibility, structure-electrochemical property relations, and novel preparation steps for scalability will be the considerations for maximizing the electrochemical performance. In situ characterization techniques e. The design of the separators will entail enhancing the safety of LIBs. The desirable porosity in the current collectors will enhance the interface conductivity. Also, scalable methods to construct electrodes will be considered for these hierarchical structured materials including 3D printing.

Phase II will culminate with prototype demonstrations that will showcase the improved next generation LIBs.

The effort through all the phases will be coordinated with the stakeholders in all the three services, which will facilitate definition of the requirements and transition of the technology. Strategic partnerships will be developed to further the commercialization potential of the technology.
