Turbine efficiency improves with increased operating temperature. Consequently, the rim zone of disks operates at high temperatures where creep is the main concern. The bore and web zones operate at lower temperatures, where strength is the driving design criterion. Procedures to produce disks that can meet both demands include dual heat-treatment and hybrid disks. A thin transition zone forms in ...

A high-voltage, high-capacity, inexpensive cathode material for lithium-ion batteries (LIBs) is proposed. The cathode material employs carbon nanotubes and additional nanostructures to support efficient transport of Li ions. The resulting LIBs will support high transient and pulsed loads while offering enhanced safety and lifecycle performance. Proof-of-concept LIB cells were demonstrated in Phase ...

For Unmanned Aircraft Systems (UAS) to operate seamlessly in both the U.S. National Airspace System (NAS) and abroad, it will be crucial that they possess a sense-and-avoid (SAA) capability that can ensure safe operations among maneuvering, non-cooperative aircraft. Numerica Corporation, in partnership with Johns Hopkins University, proposes to develop a set of algorithms to model the uncertaintie ...

A team led by NextGen Aeronautics Inc., and working with San Diego State University proposes the development of redundant wideband antennas that are embedded in composite armor structures The planned work builds upon the team’s extensive prior experience in conformal load-bearing antenna structures (CLAS), antenna design, and metamaterials. The proposed antenna is a combination of concepts that ...

The goal of the proposed research is the development of a high-volume, low-cost manufacturing along with a novel deposition process that enables fabrication of a structural-state electronic system-on film. This hybrid electronic system contains a multifunctional sensor suite that can measure a structure's static (such as deformation, stress and strain) and dynamic state (such as slow or under acce ...

NextGen Aeronautics in collaboration with Virginia Tech plan to build on our Phase I work and propose to further develop our concepts and designs for a scalable, fast and easy to use optical strain measurement system. Our proposed Phase II effort will focus on the development of a dual level optical camera system which uses one set of cameras to measure strains over the entire test specimen and a ...

The SOLUTE team’s Phase I technical approach consists primarily of a feasibility study assessing the viability of a Navy implementation of the algorithms, standards, and protocols that comprise Google's Wave technology. Of specific concern is Wave’s ability to handle varying bandwidth and DIL communications channels associated with Navy platforms. While computer science research in the field o ...

Electromagnetic launchers or rail guns are a key component of the Navy’s all-electric ship of the future, but they lack the durability required for repeated firings. TDA Research and the University of Nevada, Reno (UNR) are developing a tough, durable and conductive refractory metal coating that will protect the copper alloy conductors (rails) from the extreme heat and wear conditions inside the ...

As strontium and other alkaline-earth metals become increasingly attractive for ultracold-atom applications, there is a growing need to develop compact, robust systems for cooling, trapping, and studying these elements. In this proposal, ColdQuanta will team with Dr. Jun Ye at JILA and the University of Colorado at Boulder to develop a portable, turn-key system that can produce, utilize, and optic ...

This is a proposal to develop a unique, robust, fieldable, gated, picosecond, digital holography system for characterizing dense particle fields under harsh conditions. Many powerful imaging methods have failed to fulfill this requirement because noise from multiple scattering buries the signal needed to acquire a useful image. Solutions to this limitation are very expensive, hard to implement, an ...
