Electric motors and generators have a long history of development, from the first halting steps to the intensive development in the 20th and 21st century. Consequently, motors and generators have become mature technologies that only see incremental improvements in performance. To achieve more than just incremental improvements in such parameters as power density and efficiency, a radical departure ...

Helicopters with articulated rotor blades are subject to the well-known ground resonance where the rotor lag mode interacts, in an unstable fashion, with fuselage roll. To eliminate this ground resonance, both lag dampers and fuselage roll dampers are required. The Sikorsky UH-60 helicopter platform, which comprises the vast majority of utility rotorcraft used by the US Army and the Navy, relies u ...

EOS Photonics proposes to develop, together with MIT- Lincoln Laboratories, the next generation of high power quantum cascade laser (QCL) source with output power exceeding 15 Watts at a wavelength of 4.6 microns. The proposed subsystem will include a DFB QCL array integrated monolithically with power amplifiers, low-loss passive waveguides and optical elements aimed at realizing on-chip wavelengt ...

Maxion will develop a monolithic, beam combined array of phase-locked, buried heterostructure (BH) quantum cascade lasers (QCLs). The laser array will be designed to emit a low divergence optical beam in a direction normal to the array surface at a wavelength centered at 4.6 microns. The monolithic laser"s cw output power will exceed 15 Watts. Each ridge waveguide in the array of will contain a se ...

The predominant method used in electronic support measure (ESM) systems to detect and geolocate noncooperative RF signals employs arrays of antennas to estimate signal angle of arrival (AOA). There are several issues that preclude wide installation of these, including very high cost, challenging installation requirements, size and weight, operation that requires highly trained specialists, and pro ...

The proliferation of radar and communication devices significantly increases operators"workload. Different platforms carrying similar communication devices further complicate the problem. The onboard imaging sensors, combining with EW sensors, have the ability to disambiguate devices and platforms. Our proposed system consists of three main modules: (1) the data/time synchronization and sharing mo ...

Artificial diversity attempts to eliminate the security risks of the IT monoculture. The goal of artificial diversity is to minimize the number of common vulnerabilities across a set of systems by intentionally introducing variations to the structure and process of functionally-equivalent software. Ideally, these variations are invisible to the legitimate user but pose a challenge to the malicious ...

UUV"s have become increasingly important tools in the collection of environmental data. Their unique ability to operate independent of surface vessel conditions allows artic measures when traditional means is not possible. It is now well agreed that artic regions are critical to man"s understanding of the environment. Historically sensor packages for UUV"s have been based on"adaptions"of ship depl ...

This STTR Proposal addresses the need for a"Low cost acoustic transmitter"that combines an integrated power source, power amplifier, control-circuitry along within an innovative transducer assembly. Our approach is to use a transducer which becomes part of the housing and encloses the electronics and, moreover, uses a minimum energy to provide a sizable source level. This transducer assembly is co ...

The DOD has enacted an energy strategy that calls for both smarter energy usage and employment of alternative energy sources such that foreign oil reliance can be reduced and an increase in overall operational efficiency can be achieved. Localized generation presents an exciting opportunity for energy users in general, and the DOD specifically, to increase usage efficiency and exploit alternative ...
