21st Century Technologies’ (21CT) ACCESS (Automated Comparison and Clustering of Entity SignatureS) research effort addresses the issue of comparing entities such as human personas and networks, so that a more complete assessment of at-risk entities can be made within and across the various domains in which those entities interact. The Phase I effort of ACCESS will provide an effective similarit ...

Although the performance of naval systems for Anti-Submarine Warfare and Counter-Torpedo Detection, Classification, and Localization systems are presently adequate for current missions they are limited by the size, power and detection range of the associated sonar transducer arrays. What is required for the emerging missions are approaches that will reduce the volume and weight of present arrays w ...

Friction stir welding (FSW) can produce stronger, lighter, and more efficient welds than any previous process. In aluminum assemblies, FSW provides improved joint strength, fatigue properties and crack resistance compared to conventional arc welded joints. One of the current barriers to widespread use of FSW is that the process generally requires the use of clamping systems that are often cumberso ...

The proposed research will explore innovative flight control methodologies combining recent advances in system identification, novel flight sensors, and neural network based adaptive flight control design to develop a new, high bandwidth flight controller architecture capable of rejecting the disturbing effects of wind gusts and turbulence. The proposed controller architecture will be most appropr ...

Navy ships use of gas turbine engines for both main propulsion and electrical power generation. With typical simple cycle thermal efficiencies of around 32-35%, a great deal of energy is lost as exhaust waste heat from the gas turbines. Clearly there is a need to develop systems that can recover as much as possible of this waste energy, and as stated in the program goal, achieve at least a 20% red ...

The demand for greater and safer energy storage for the wet and dry submersibles has pushed the limits of current battery technology. This energy demand is in response to the need for extended underwater mission operations and advances in electronic equipment needed for greater combat effectiveness. By replacing the existing battery with a fuel cell hybrid system, extended operation periods are po ...

Develop a high power to weight, compact, heavy fuel MCC engine using advanced high strength materials. This new MCC engine design will also offer high durability and high efficiency with an extremely low acoustic and IR signature for use in future small UAVs. The overall objective of this Phase I development program is to develop a JP-5, JP-8 or DS2 MCC engine using advanced high strength to weigh ...

Rechargeable lithium-ion batteries with improved safety, abuse tolerance, reliability, and volumetric and gravimetric energy densities are needed for Navy aircraft including the Joint Strike Fighter, H-1 Light Attack Helicopter, and other aircraft. Despite their high energy densities, current lithium-ion batteries can combust and release highly toxic chemicals under failure mechanisms such as over ...

MNB Technologies presents a novel approach to integrating mission-specialized adaptive knowledge fusion front-end systems to their unique hardware accelerated real time synthetic holography visualization engine and projector. The result of this will be a portable distributed system that may be used to integrate disparate information into a cohesive volumetric perspective of the battlespace from se ...

Sensitive equipment critical to successful LCS missions have been damaged due to excessive shock loading. The shock is transferred to the mission systems through rigid twist-lock connectors which secure mission module ISO containers to the LCS hull. TRI/Austin proposes to investigate state of the art shock mitigating materials and structures to resolve this issue. A preliminary design of a composi ...
