Triton Systems, Inc. proposes to develop an affordable, lightweight and durable hybrid composite system for next generation structural frame composites that will survive both short- and long-term thermal and chemical exposure and abrasive conditions. The team will develop a hybrid materials system that is an improvement on traditional carbon fiber reinforced polymer (CFRP) systems in performance a ...

This STTR aims to develop a novel method for detecting and tracking growth of cracks in rotorcraft gearbox. Aerospace structures are subject to dynamic loading. In particular, gearbox components experience continuous cyclic loading, wear and eventually develop fatigue cracks. As opposed to most other aircraft components, gearbox components are non-redundant, so a failure can have catastrophic cons ...

The Navy seeks to develop new, innovative motor/generator technologies that can effectively operate at speeds up to 1,000 kRPM at power densities of 40 kW/kg (excluding heat exchanger) with an overall system efficiency of 95% or better. Such a motor/generator will have a wide range of applications, i.e. it can be used as the core building block of a very lightweight electrical energy storage syste ...

Diver communication is vital for the US Navy while carrying out strategic underwater missions. Diver-to-diver communication and diver-to-vehicle communication can allow the sharing of information as it is discovered and also enable performing cooperative maneuvers. Emergency situations can also benefit from such communication. In addition to the communication capability, it would be useful to know ...

The implementation of structural health monitoring (SHM) systems into naval applications has been hindered due to component quantity, including sensors, power/communication cables, and acquisition/computation units, as well as data quality. Particularly for large-area applications such ship hulls, complexity of implied system infrastructure can be impractical, and data can be worthless with attenu ...

The main objective of the Phase II work is to enhance the FORECAST algorithms developed in Phase I, extend them to 3D in the case of multi-rate sensors and significant wind effects, develop effective tuning procedures, and evaluate the performance of the FORECAST system on test data. In order to achieve these objectives, we plan to carry out the following tasks: (i) Extend FORECAST algorithms to 3 ...

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 proposed work will address the core physics underlying acoustic reverberation as related to properties of the ocean environment and properties of the acoustic sources, receivers and waveforms that make up ocean-going acoustic systems of interest to the U.S. Navy. Present day active acoustic system performance models, which contain reverberation models as an essential component, are over twenty ...

The Internet of Things (IoT) connects people, data, and "things" (e.g., software, sensors, platforms), facilitating the translation of information into actions. Although naval platforms’ networks and communication suites have evolved significantly in the past few years to support such required connectivity, one of the greatest technical challenges still facing the military community is the proce ...

Resource virtualization concepts are in heavy commercial use for optimizing the performance of distributed applications. Resource virtualization allows resources to be allocated and adapted on-the-fly, and enables a wide range of distributed computing, networking, and sensing applications. However, resource virtualization has traditionally been developed for fixed, stable networks, and cannot adeq ...
