Thermal batteries are single-discharge reserve batteries that provide a very long shelf life, minimal self-discharge, wide storage temperature range, fast activation under sudden power demand, and also a wide range of temperature operating conditions. 32Upon activation, thermal batteries are heated with an internal pyrotechnic heat charge above the melting temperature of the molten salt electrolyt ...

Electrochemical double-layer (ECDL) capacitors have tremendous potential as high-power delivery energy storage elements in low-volume and low-weight microelectronics systems. ECDL electrodes based on nanostructured carbon offer the potential for exception

Missile threats faced by our country are constantly increasing in lethality. The weapon used to counter such missiles is the kinetic interceptor. To work effectively, the reentry vehicle (RV) location must be precisely known. Confusing objects within the reentry complex make the key discrimination process very difficult. Coherent distributed aperture (CDA) radar represents an important advance in ...

Virtual AeroSurface Technologies, Inc. in collaboration with Georgia Tech and Raytheon Company proposes a Phase II STTR program for the development and testing of meso- and micro-scale Pulse Tube Refrigerator cryocooler systems. The Phase I program performed numerical modeling and CFD simulations of the small-scale effects (e.g., increased surface area to volume ratios with relatively greater fri ...

JRD, Raytheon, and Tuskegee University have successfully completed the Phase I effort for design and development of an advanced solid state cryocooler for infrared sensor components. In addition, it was decided that the lowest-risk path forward for Phase II is the two-stage hybrid pulse tube / Joule-Thomson design. These initial calculations predict that efficiency potential of the solid state c ...

This STTR program, Topic MDA07-T011, aims at developing an array radiator for low-cost X-band planar phased array antenna with over 50% reduction in LCC (life-cycle cost), which currently is prohibitively high. The phased array must be planar, wideband, and compatible with the fabrication process of low-power T/R modules. In Phase-I, Wang Electro-Opto Corporation (WEO), Ohio State University, and ...

To realize next generation missile defense radar systems with a significant improvement in performance requires more cost effective system implementations. Software defined radar (SDR) technologies together with field programmable gate array (FPGA) implementations promise reusable and low cost DREX multichannel receivers in smaller form factors. Real time firmware reconfiguration enables radar mod ...

In the proposed effort we plan to build a fully-operational X-band T/R Integrated Circuit. One of the key-elements to building a fully operational radar is the requisite RF electronics that feed to each antenna element. Historically, radar transmit/receive (T/R) modules have been implemented as complex, multi-chip GaAs MMICs, resulting in very high cost per T/R module, high launch weight, and high ...

Our missile defense capability crucially depends on radar performance to detect, track and discriminate hostile targets. New radar designs being developed offer enhanced capability. However, a significant impediment to the deployment of these new radars is the high cost of active electronically scanned arrays (AESAs) and in particular the antennas upon which they are based. Together with our inter ...

Virtual AeroSurface Technologies, Inc. and the Georgia Institute of Technology propose an STTR program for the investigation and modeling of meso scale Pulse Tube cryocooler systems (with initial design targets of 0.5 mW exergetic cold end thermal loads and cryocooler volumes of approximately 10 ml), with the possible extension of models further into the micro scale. CFD-based models will be deve ...
