Free electron lasers (FEL) made from Nb cavities offer high performance, but they are complex, bulky, and expensive. For Navy FEL applications, where footprint, power consumption, and cost are severely constrained and reliability is of great importance there is a critical need for an alternative to Nb. MgB2 is a recently discovered superconductor with a high critical temperature and critical field ...

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 rapid prototyping simulation for the Autonomous Rotorcraft Land & Take-Off (ARLTO) system will be developed to analyze and evolve requirements for the landing and take-off of a Rotary-wing Autonomous Air Vehicle (RAAV) from unprepared terrain. The simulation is based upon the Task-Pilot-Vehicle modeling system and features a UH-60 configured with a Sliding Mode Control (SCM) inner loop closure. ...

TSC and Purdue University will demonstrate a lab prototype of software and hardware capable of doing high speed monitoring of a Lithium-Ion cell. This monitoring needs to be specifically designed to predict failures. When a predictive failure is indicated a defensive countermeasure needs to be implemented. Our specific project goals are to: 1) Select a Lithium-Ion battery that consists of multiple ...

The Navy has need of assessing the river environment including bathymetry, flow velocity profile, and navigational obstructions. While improvements in measurement fidelity and reduction in cost have come about by the use of multiple drifters, measurement quality is lost due to convergent drifter trajectories, and cost/risk remains high due to personnel effort required for deployment. An autonomous ...

Yotta Navigation and The Ohio State University propose to develop a complete diver text messaging and locator system. The system will securely transmit preformatted and free-text messages, and will be able to accurately determine range and bearing, at distances of up to 1000 meters. This system consists of two major components. An ultrasonic cylindrical array, mounted on a swimmer delivery vehicl ...

G2 Software Systems (G2SS) proposes to explore all features of Google Wave to develop practices and extensions to support Navy Command and Control (C2) processes. The C2 practices and extensions include tools for collaborative problem analysis, collaborative planning, knowledge sharing, knowledge awareness (searching and registering for critical information requirements), knowledge context (includ ...

Existing riverine drifters are passive devices designed to capture, store and transmit river flow and bathymetry information. Problems inherent with passively drifting devices include the inability to maintain uniform cross-stream spatial coverage and lost drifters due to unintentional grounding and entanglement with various hazards present in a typical river environment. This proposal outlines a ...

We propose to design, develop, implement, simulate, and demonstrate an autonomous control and sensing system for the safe vertical landing of autonomous aerial cargo delivery system (ACDS). The landing site is expected to be unprepared mountain sides with slopes up to 15 degrees and rough terrain containing rocks and brush. We also plan to reduce the amount of ground equipment required to operate ...

Current software development and testing methodologies are inadequate for validating software in mission-critical applications. As Dijstra famously stated: "testing can be used to show the presence of bugs, but never to show their absence." When lives and national security is at stake, there is a need for mathematically rigorous techniques that can verify the absence of bugs. We propose to devel ...
