AstroPower is developing a two-junction monolithic tandem solar cell composed of (AlxGa1-x)0.51In.49P lattice matched to GaAs for use as the top cell in a three-junction, two-terminal tandem stack. This tunable bandgap material system is capable of current matching, at 2.03eV, in a two-junction monolithic tandem solar cell two terminal design of (AlxGa1-x)0.51In0.49P/GaAs yielding a best case pred ...

FOR CATHODIC PROTECTION SYSTEMS TO BE SUCCESSFUL IN MITIGATING CORROSION WITHOUT CAUSING HYDROGEN EMBRITTLEMENT OF PRESTRESSING STEEL, THE AMOUNT OF POLARIZATION OF THE EMBEDDED STEEL MUST BE VERY ACCURATELY CONTROLLED. PRESENTLY AVAILABLE EMBEDDED REFERENCE ELECTRODES DO NOT HAVE THE LONG TERM STABILITY OR RELIABILITY RE@UIRED TO MONITOR AND CONTROL THE AMOUNT OF POLARIZATION WITH THE ACCURACY RE ...

Decisive Analytics proposes build a executive sensor resource management algorithm that (1) extends the algorithm successfully demonstrated in Phase I to globally task sensors to meet system tracking and discrimination needs; (2) is tailored to work with discrimination fusion engine algorithms currently being deployed to be BMDS; and (3) is compatible with future system requirements for which ther ...

Under this Phase II SBIR, the Decisive Analytics Corporation (DAC) team proposes two advanced capabilities that are not currently supported in the Ballistic Missile Defense System (BMDS). Employing ground-breaking techniques developed under Phase I of this effort for describing and solving the problems of tracking and discrimination within a single Bayesian network model, we propose the developmen ...

Accurate collateral damage assessment is of critical importance for missile defense because determining the likelihood of a successful intercept kill is required for efficient interceptor tasking. This is especially critical for first generation missile defense systems that are likely to only have a limited number of interceptors available to address a very wide spectrum of threats. The primary go ...

Certain ferro-magnetic (F/M) materials expand and/or contract in the presence of an electrical current or field. This program proposes basic and applied research to use this material property as the working medium to achieve quantum improvements in the performance of miniature actuators. Using this exciting new solid state technology, it appears possible to create ultra-fast response, high force, ...

In the Phase 1 Feasibility Study, we examined weapon-target engagement scheduling problem, and developed a rapid software prototype to demonstrate automated, optimized, scheduling with the use of simulated realistic missile battle scenarios. Scheduling of an intercept launch was predicated on the engageability and lethality of the weapon-target pairings: Lethal intercept opportunities for all weap ...

The proposed Phase II work is mainly focused on further continuing and developing Composite Alloys of W-25Re, Mo-Re, with Ta, Hf, HfC, and TaC for the application development of higher thrust-high temperature (e.g., TDACS FEDS) Large Thrust Pintles with potential weight reduction by suitable alloying and functional layering for advanced Solid DACS systems using UTRON’s 300, 400 or 1000 Ton CDC P ...

In this SBIR, VPT has proposed a point-of-load (POL) power converter that is immune to radiation effects, including total dose, prompt dose, and SEU. Such a RH-POL converter addresses the demanding low voltage, high current, power requirements of advanced data processing circuitry in MDA applications. In Phase I, VPT built on its recently-introduced military thick-film hybrid DC-DC POL power conve ...

2Superconductors, materials that carry electrical current without any resistance, can make electronic circuits more efficient and communications between remote locations easier. In the past two years, the materials developments of superconductors have progressed so much that the quality of the materials can no longer be measured even with the most sophisticated techniques. Xsirius Superconductivit ...
