The predominant method used in electronic support measure (ESM) systems to detect and geolocate noncooperative RF emitters employs arrays of antennas to estimate signal angle of arrival (AOA). There are several issues that preclude wide installation and use of these for emitter geolocation. One issue is accuracy. There are various error sources, including signal noise, multipath effects, and ambig ...

The United States is currently faced with unprecedented energy challenge. Petroleum prices have skyrocketed due to rising competition for energy resources from emerging economies. There is a significant need for processes that can produce hydrocarbons from renewable resources rather than petroleum. The use of renewable resources ensures a long-term supply of hydrocarbons, even after easily extract ...

Secure, domestic sources of rare earth elements (REE) would be of great strategic importance to the Department of Defense, as well as many commercially important industries. Our approach takes advantage of an abundant and low cost source not previously co

This STTR Phase II Proposal addresses the need for a low cost acoustic transmitter that combines a power amplifier, control-circuitry and an innovative transducer assembly, all at a low cost. Our approach is to use a cylindrical modal vector projector transducer which becomes part of the housing and, moreover, uses only a minimum of power to provide a sizable source level. The modal vector project ...

Recovery and re-use of Rhenium is of critical importance to the superalloy industry due to its limited availability and growing demand. The recycling loop in the superalloy industry is currently far less efficient.The proposal addresses the recovery of Rh

In recent years, the need for highly reliable, durable and non-intrusive systems for monitoring the health condition of naval structures becomes more and more recognized. Of particular importance is the condition based maintenance of Navy rotating machinery (motors, generators, pumps, gear systems, etc.). Such Structural Health Monitoring (SHM) systems should be able to detect failures in their ea ...

The primary goal of this STTR program is to develop high fidelity LDLP software module that can predict stiffness and damping forces over the ranges of amplitude, frequency, and temperature appropriate for comprehensive modeling of helicopters. The LDLP module will focus on enabling accurate prediction of the onset of both air and ground resonance, as well as the fatigue loads that would arise due ...

Areas of research relating to self-healing composites structures have been undertaken by well-known and respected research institutions under the auspices of the Department of Defense. Patent literature and public technical communique describe their novel engineering approaches using polymeric healing agents through suitable mechanisms. While these approaches have merit, the choices of materials u ...

Aerodyne Research, Inc. (ARI) and MIT are collaborating to extend their successful Phase I effort to fully develop and validate a comprehensive JP-10 combustion mechanism, using a novel automatic reaction mechanism generation tool (RMG) developed at MIT. JP-10 is a very attractive, but complex fuel whose combustion chemistry is poorly understood. In Phase I, the ARI/MIT team successfully developed ...
