Performing accurate simulations of large- and multi-scale electromagnetics problems has far-reaching implications in a variety of engineering and scientific disciplines. The same physics governs a diversity of applications including problems of importance for NAVAIR such as complex radome-antenna and antenna-platform interactions.  Such simulation problems involve complex materials, multiple feed ...

We propose to develop a heterogeneously integrated optical transmitter for balanced radio-frequency (RF) photonic link applications on air platforms that incorporates a high-power Nd:Glass laser source operating near 1054nm. During Phase I, we will develop a Nd:Glass prototype laser using a design that has already been  used to demonstrate hundreds of mW of single-longitudinal mode (ultra-narrowb ...

In resource limited settings, rapid and accurate diagnosis of infections is critical for managing potential exposures to highly virulent pathogens, whether occurring from an act of bioterrorism or a natural event. This is especially important for hard to detect intracellular bacterial and alphavirus infections, that overlap symptomatically and often treated empirically due to a lack of reliable an ...

The Phase 1 results demonstrate the feasibility of using Bayesian Inference techniques with ML AI engines to augment the cognitive decision processing resident in LSI’s RM for eventual integration within the RM/Navy Mission Processor that is transitioning to the Navy. The proposed Phase 2 effort will further refine the use of Bayesian Inference with AI as enhancements to LSI’s RM. The use of ...

Cataclysmic changes in how we communicate in cyberspace are dramatically altering our society, allowing information to spread faster, farther, and with less assurance of its accuracy, and enabling groups to form and recruit members on-line to foster social divides. Organized social media manipulation has more than doubled since 2017, with at least 70 nation states employing computation assisted te ...

For decades gas turbines have been a reliable source of propulsion for a variety of marine-based vehicles. Since their adoption as the go-to solution for vehicles requiring a higher power density than conventions diesel engines can produce, they have suffered from corrosion of their alloyed components. Long believed to be the primary source of the corrosion, great efforts have been made to reduce ...

The "Hybrid Integration of Photonics and Cryogenic Electronics with Magnetic Shielding (HIPCEMS)” effort will develop a scalable heterogeneous packaging plan which results in extreme energy efficiency information transfer at high clock rates and low bit error rate of digital data between superconducting and photonic technologies, each at 4K. HIPCEMS will feature a mechanically robust package tha ...

Improved propeller designs for Small Unmanned Aerial Systems are needed to improve performance and reduce acoustic emissions. Traditional propeller design methods don’t take advantage of advances in coupled fluid, structure and acoustics computational design methods nor advances in high strength, high modulus materials to extend performance of propellers and reduce noise emissions. In the propos ...

Small Unmanned Air Systems (UAS) are critical to deploying sensors, communications and other mission payloads, however, UAS noise, most notably propeller noise, can jeopardize mission success because vehicles can be detected beyond the range of payload effectiveness.  Continuum Dynamics, Inc. and Georgia Institute of Technology propose to develop a new class of highly efficient ultra-quiet propel ...

The US Navy has identified refractory high entropy alloys (RHEAs) and metal additive manufacturing (AM) as enabling technologies to meet performance and sustainability targets for shipboard and aircraft systems. Key challenges include designing RHEAs and optimizing metal AM to achieve desired material properties for Navy propulsion applications. Developing materials and processes via traditional e ...
