A multi-scale/multi-physics software tool will be developed to predict manufacturing-induced defects, specifically void evolution during composites manufacturing, due to materials, parts, tooling and process parameters. Appropriately modeling the manufacturing process to identify potential problem areas will enable process optimization to produce structural components without defects. Specifically ...

Triton is proposing to continue developing a family of preceramic materials and formulations that will produce group 4 (Zr and Hf) carbides and carbide/boride mixtures in good yield. The target yield for the program is 60 vol%. These materials will be used in a polymer infiltration and pyrolysis process to produce ultrahigh temperature ceramic matrices in ceramic matrix composites useful for hyper ...

This project researches the feasibility of creating a self-powered buoy system. The technology being investigated is a means of efficiently extracting energy from ocean wave dynamics. The mechanics of ocean waves is such that they contain significant energy in the water motion and pressure changes. If a portion of that energy could be efficiently extracted, it would easily be sufficient to powe ...

Physical Sciences Inc. and the Pennsylvania State University (Professor Stefan Thynell) propose a novel gas generator concept utilizing inert and safe ionic liquids as monopropellants and innovative techniques for their fast ignition and stable, sustained combustion. An STTR program is proposed to develop the concept into a gas generator system that can be operated only when needed and responds e ...

Advances in modeling and simulation, networking, and computer graphics technology have made it possible to conduct large-scale, distributed LVC training events, such as the Navy’s Fleet Synthetic Training-Joint (FST-J) exercises on a regular basis. However, FST-J exercises are not without room for improvement. Instructors and exercise controllers often confront difficulties assessing the state ...

An innovative concept for a scalable Digital Beamformer that can be applied to the full range of Navy radars/RF communication is proposed. The concept is photonics based and will support transmit/receive applications over the 0.1 to 40 GHz, and V bands. The design provides a digitally controlled True Time Delay based Beamformer effectively adaptive to a phased array in any portion of the spectral ...

New technology is needed for the nondestructive inspection (NDI) of defects in gas turbine engines. This is particularly true for components such as turbine blades with fretting fatigue defects that are difficult to detect and characterize with existing NDI equipment. The lack of detailed flaw detection and characterization raises safety concerns, hampers fleet readiness and negatively impacts the ...

Accurate assessment of burn depth and surface area are important to clinical decision-making regarding treatment. Initial assessment determines fluid requirements and transportation decisions to distant-care facilities. The clinician must determine if the wound will heal itself or whether excision and grafting are necessary for optimal wound healing. The standard of care remains visual inspection ...

SatCon proposes to fabricate and test an advanced technology electric drive for improved power density and quiet operation for underwater propulsion systems with an initial focus on torpedo applications. We will leverage our experience in SiC applications, NUWC propulsors, and active ONR podded propulsor program as a baseline design, and couple this with the design analysis and modeling expertise ...

Acumentrics, Wright State, and GoHypersonic are partnering to deliver a robust solution to the need for power generation for long duration hypersonic platforms. This solution considers not only the direct generation of power using a highly efficiency fuel cell package, but overall vehicle requirements. This work utilizes existing commercial technology in developing this unique solution.Specific po ...
