75554B Fuel cells are an efficient, combustion-less, virtually pollution-free source of power. In particular, Proton Exchange Membrane (PEM) fuel cells are ideal for a number of applications, due to their ¿quick¿ warm-up characteristics. However, these fuel cells contain some inherent inefficiencies, which results in waste heat that must be removed rapidly via a coolant ¿ currently, either D ...

Ribbon Mills and its subcontractor Northrop Grumman Corporation (NGC) propose a Phase II program, to continue the research into advanced complex performs concepts utilizing weaving technology applied to state-of-the-art composites to enhance the revolutionary low frequency, conformal load-bearing antenna structures (CLAS) foliage penetration ground/air moving target indicator (FOPEN GMTI/AMTI) rad ...

The design of turbomachinery components is a complex process requiring many steps and hundreds of minute decisions in an iterative process. The design proceeds from engine cycle performance and meanline design through 3D viscous flow calculations (CFD) and finite element structural analysis (FEA). Design studies may traverse this process many times, with routine tasks performed by engineers in a ...

We propose to develop an earth penetrator with improved shape for trajectory stability during high-speed penetration. Several promising penetrator shaping concepts have been identified in Phase I. Through further analysis, one or two of these will be selected for further development. Penetrator designs will be formulated and optimized, then tested through gun firings of scale-model penetrators int ...

The project focus is the development of a ground target tracking algorithm to support the JSTARS radar operating in the GMTI mode. Multiple hypothesis tracking (MHT) algorithms maintain alternative data associations to represent report-to-track association ambiguities. In Phase 1 we developed a prototype MHT algorithm not requiring the Bayes’ posterior distribution for the target state to be G ...

The design of Unmanned Aerial Vehicles (UAV’s) is a complex process of creating a reliable system of reasonable cost that can survive in hostile environments. Although UAV’s have unique aspects to them, similar goals can be found in almost any complex, competitive product. One aspect of the design of these systems that tends to be both difficult and poorly supported with available computer ...

75272B Transmission Electron Microscopy is a technique that allows materials to be analyzed to the nanometer and sub-nanometer scales. The next level of materials analysis will require the ability to perform dynamic experimentation within the microscope, which would require specialized specimen holding technology to perform the desired experiments. This project addresses the treatment of a spec ...

The development of durable thermal protectin systems is one of the critical technologies to enhance performance and reduce operational costs of the next generation reentry space vehicles. k Technology Corporation (kTC) proposes development of an integrated thermal and structural thermal protection system (TPS) with low maintenance. The concept is to develop a leading edge TPS that is a load-carr ...

75353-Low cost, self-powered wireless sensors that never require battery changing or other maintenance are needed for U.S. industrial production lines, in cars and buildings, and power generation systems. Systems of these sensors will enable a revolution in industrial efficiency, safety, and reduced maintenance costs. This project will develop a wireless sensor with an integrated vibration-power ...

The use of coated HT superconductors in the ac windings of electrical machines offers the possibility of much lighter electrical devices. To use these conductors at proposed high frequencies, present “as-manufactured” conductor geometries must be modified to reduce their ac loss by using fine filaments and other topologies). Equally important are more global winding losses requiring suitable ...
