Through the proposed Navy STTR program, NanoSonic and Virginia Tech will create, qualify, and commercially transition a paradigm breaking HybridSil anti-icing and icephobic coating specifically engineered for extreme environmental durability, ease of application, and low-cost for U.S. Navy ship superstructures. The offered nanocomposite coating will leverage NanoSonics anti-icing and icephobic coa ...

To address the Navy"s need for a common, scalable, platform for multi-modal 1pA level current sensing for Electrocardiogram (ECG), Electroencephalogram (EEG), and Electrodermal Response (EDR) to be fielded as a miniature wearable device with non-contact electrodes, Sentient and the State University of New York (SUNY) propose to develop the Bioelectronic Fusion Sensor System (BioFuSenS) that will a ...

ABSTRACT: The innovation proposed is a computationally-tractable, physics-based, portable turbulent combustion modeling strategy for application to a wide range of Air Force aero-propulsive systems, including augmentors, liquid rockets and scramjets. This modeling strategy will be implemented within an Application Programming Interface (API) library suitable for easy integration within Air Force ...

ABSTRACT: The Air Force Phase I program would develop and demonstrate semiconductor nanomembrane (NM) based sensors and arrays for high frequency pressure measurements, using SOI (Silicon on Insulator) NM technique in combination with our pioneering HybridsilTM copolymer nanocomposite materials. NanoSonic would work cooperatively with Virginia Tech to develop an improved mechanical and electrical ...

Most of current available methods for prediction of fatigue failure -such as cumulative damage models, cyclic plastic energy hypothesis, crack propagation rate models, and empirically-derived relationships -are based on empirical relations and their application requires many unknown parameters that must be experimentally determined or calibrated for specific locations/critical areas. Also, the afo ...

This DOD Phase I STTR program would develop III-V multijunction based solar cells, using Virginia Tech"s InGaP/GaAs/InGaAs multijunction cells technique in combination with NanoSonic"s pioneering Hybridsil antireflection copolymer nanocomposite materials, which afford high levels of antireflection, temperature and abrasion resistance, impact durability and hydrophobicity (self cleaning). Such an a ...

Historically, aircraft engines have featured relatively simple axisymmetric exhaust shapes with several moving parts; however, future engine exhaust systems are expected feature compact, sinuous ducts with complex non-axisymmetric shapes, fixed exit areas, thrust vectoring etc., constructed with a minimum number of moving parts. Their exhaust plumes are currently not well understood; however, LES ...

The major objectives of the Phase I effort will be focused on CDC higher pressure combustion (using natural gas or hydrogen-GREEN MANUFACTURING) driven powder compaction fabrication of select alloys for Microwave Tube Related Component end uses for NAVY using powders of varying sizes and vacuum-grade purity such as Cupro-Nickel, Stainless Steels (e.g., 316 LN, Custom 465 high strength version), Mo ...

This proposal describes a new process to facilitate the shock qualification of submarine components, taking advantage of the similarities between readily observable design features of these components, and correlating them to success or failure in Navy shock qualification tests. To realize this Design Feature Similarity (DFS) approach, we will develop a set of criteria based on this type of readil ...

A database-driven approach is needed which characterizes the failure modes of the mechanical components of submarine systems under extreme loadings. Such an application must provide automation of the component shock qualification process through an automated capability while providing component-level qualification based upon similarity of components and failure modes. Certification of shock worthi ...
