Oceanit proposes to research and develop chemical or non-chemical methods and processes to impart surface morphology modifications to aluminum-magnesium (Al-Mg) alloys to mitigate and increase the exfoliation corrosion resistance.

ABSTRACT: We will develop a multiscale molecular dynamics/material point method (MD/MPM) methodology for determining the response of PBXs to a wide range of loading conditions as a function of mesoscale structure with emphasis on accurate representation of interfacial physics. The initial material of choice will be HMX + DOA plasticized HTPB binder. Velocity-dependent grain-grain and viscoelastic ...

In phase I, we have proven the feasibility of using the microwave cavity perturbation technique to detect and quantify DoS in marine aluminum alloys. We implemented an alpha version sensor prototype, characterized and validated its performance using ASTM G67 method. We also identified methods to further enhance the sensor sensitivity, so that DoS in the low (a few mg/cm2) to moderate range can be ...

In this proposal, AlphaSense, Inc. (AI) and the Pennsylvania State University (PSU) detail the development of a novel noninvasive microwave sensor to quantify the DoS in marine aluminum alloys. The key innovations of this proposal include the following: a) DoS quantifications based on the correlation between the surface resistivity with the microstructures of the aluminum alloys, b) measurements o ...

Next-generation high-performance computers (HPCs) are built as massively parallel systems where the parallelism exists at many levels. These systems are a collection of nodes all working together. Each node generally contains more than one processor and each processor contains multiple cores. Managing and efficiently utilizing the different parallelism in such a system is a complex task. Furth ...

Composites manufacturing using autoclave cured pre-preg materials is expensive, often size limited, labor intensive, and has slow cycle times limiting production. The AFRL reported the need for improved composite research and demonstrations related to the emerging Advanced Air Mobility market. This project will use novel, out of autoclave composite manufacturing methods including composites based ...

Investigations into JP-10 combustion chemistry thus far can be characterized as preliminary. The detailed chemical kinetic mechanisms that have been published are limited in their ability to reproduce experimental data. The combustion chemistry of JP-10 is highly complex, involving hundreds if not thousands of species and thousands of chemical reactions. A detailed kinetic model capable of predict ...

In the realm of cyber operations a compromised identity puts warfighter lives at risk and may result in failed operations. The cyber operator of today needs to contend with the next generation of online counterintelligence (CI) and protect their cover. Ne

Current Problem: With the proliferation of unmanned, AI-enabled enemy systems across the battlespace, without a new capability, we simply cannot field enough highly capable manned systems (fighters and bombers) to ensure air dominance 24/7/365. Therefore, we must rely on asymmetric force multipliers that bring to bear overmatch in every domain, including air.  So, the first problem is that our a ...
