Towing of a Magnetic Anomaly Detection (MAD) system is an important aspect of rotorcraft maritime operation in support of Anti-Submarine Warfare (ASW). The vibratory rotary wing platform combined with the long and flexible towing cable, the low mass ratio of the towed body to the total mass (the sum of the tow body and the towing aircraft), and the rotor downwash impingement on the towed body duri ...

In this STTR effort nGimat will partner with the University of Kentucky to develop a new process for manufacturing scandia-doped tungsten powder for use in vacuum tube cathode devices. While a significant amount of research over the last several decades has shown promise for scandate cathode materials, reliable manufacturing processes that enable commercialization of this technology have remained ...

Vacuum Process Engineering Inc. in collaboration with the UC Davis millimeter wave research group proposes to develop a large scale production process for nanocomposite scandate tungsten powder for advanced high current density and long life thermionic cathodes that have been previously demonstrated by UC Davis to be superior to the commercially available state-of-the-art. The produced cathodes de ...

Thousands of years of evolution have produced the human vision system that computers cannot replicate well. Humans are still unsurpassed in their ability to search for objects in visual scenes. To successfully detect objects in cluttered scenes, the human brain is thought to rely on multiple factors: prior probabilities of object occurrence, global scene statistics and object co-occurrence. Machin ...

The Navy is interested in developing hybrid superconducting power transmission cables that would carry at least 5 kA of current and have a current density of at least 35 MA/m2. The cable should be able to carry 30 % of the rated current even when the superconducting cable fails. We propose to develop a hybrid superconducting cable, based on CORC cables, which potentially have a current density of ...

This research will show how data-capable laser communication retro-reflectors integrated with multispectral image processing can provide extreme reliability positioning suitable for full time automatic landing aboard ship of piloted fixed wing aircraft. The positioning system supports the SALRS long-term objective to reduce or eliminate pilot training to perform manual landing aboard ship includin ...

This Navy STTR Phase I proposal presents an unprecedented NDI tool to support laser additive manufacturing of metal parts by using fiber laser SAW and heterodyne detection. It is the enabling technology for real time characterize the AM parts in terms of temperature, cooling rate, grain structure, and defects. A proof of concept demonstration will be carried out at the end of Phase 1.Prototypes wi ...

We propose development of a software capability which, based on use of MathSysaccurate and efficient exact-physics computational electromagnetics (CEM) solvers, will enable modeling and optimization of the properties of on-platform pRFID tag/reader antenna systems. Passive Radio Frequency Identification devices (pRFID) mounted on complex rotorcrafts pose challenging modeling problems: since pRFID ...

To handle the so-called black start fault contingency, Energy to Power Solutions proposes the use of a novel hybrid cable design. The cable would be designed to handle the full 100 % electric power load under normal operating and battle conditions (i.e. a fully/partially functioning cryogenic cooling system operating at cryogenic temperatures ~ 50-60 K), and capable of handling 30 % of the rated p ...

Additive manufacturing (AM) is a very promising technique for rapid, low-cost production of aircraft parts directly from a CAD file. AM is especially appealing for complex parts that would be costly or impossible to fabricate by machining or casting. At the current time there are no reliable, cost-effective techniques to qualify the finished parts. Several government studies have noted this gap an ...
