ABSTRACT: During Phase I, SES modeled the fuel consumption of a baseline shelter and then modeled the interactive effects of using fuel efficient technologies (lighting, climate control, etc.) instead of the baseline technologies. This work demonstrated the feasibility of improving the fuel efficiency of shelters by more than 50%, by combining several innovative commercial off the shelf (COTS) t ...

ABSTRACT: Select Engineering Services (SES) has developed a composite Instrument Landing System (ILS) tower that improves sustainability (by eliminating costly maintenance) and increases airfield safety through a frangible design. Current ILS towers are made from steel components and require costly Mobile Depot Maintenance (MDM) to mitigate corrosion. The development of frangible structures has p ...

Accelerators used for nuclear-physics research require megawatts of radio-frequency energy. They currently employ vacuum-tube power amplifiers or conventional solid-state amplifiers that are inefficient and therefore consume a great deal of prime power. Many other applications including semiconductor processing, cellular-telephone base station transmitters and military communication systems simila ...

SOFC technology promises to provide an efficient method by which electricity can be generated from coal-derived syngas, biofuels, and natural gas, while increasing energy security and reducing greenhouse gas emissions. The large capital costs attributed to the cathode low performance and long-term stability issues are a current limitation of SOFC technologies that must be addressed before commerci ...

ABSTRACT: Cavitation which leads to head falloff and feed system instabilities are a constant source of problems for the low net positive suction head (NPSH) pumps that are needed for advanced liquid rocket engines. Head falloff limits the pumps capability to deliver propellant at the required pressure and cavitation induced instabilities are a significant source of structural failures in rocket ...

Conventional indoor environmental monitoring technologies are expensive, cumbersome to install and maintain, and do not provide the distributed granularity required to capture the necessary details for efficient energy management of commercial buildings. Developments in wireless sensor networks (WSN) provide substantial framework for monitoring and addressing indoor environments at scale. However ...

ABSTRACT: A need exists for a reliable, low cost radiation-hardened digital memory in aerospace and defense applications and in long-life, high-speed memory for terrestrial and commercial applications. Present offerings can accomplish the objective, but only at the expense of performance, power, size, and weight with device redundancy and shielding. Recent focus on Graphene and its capabilities ...
