Detecting and Avoiding (DAA) manned aircraft from small Unmanned Aircraft Systems (sUAS) remains the unsolved problem for safe integration of sUAS into civil airspaces where Navy UAS must pay Due Regard to the laws of civil aviation. The difficulties are manifold. The solution requires both ultra-low SWaP sensors that track aircraft over long ranges, providing 360o field-of-regard (FOR), and often ...

High power semiconductor devices suffer from difficulty in dissipating heat and thermal stresses. Silicon carbide-based power modules, in particular, have increasingly challenging heat loads despite their high efficiencies. In general terms, the module packaging methods used to improve cooling (moving metal heatsinks closer to the die) also increase thermal stresses, and the methods used to reduce ...

Advancements in electronic warfare driven by sophisticated sensors and weapons are pushing shipboard power distribution systems to higher voltage, more power dense solutions. Reduced cost and increased flexibility necessitate solutions that are rapidly scalable and are characterized by longer life and lower maintenance. These objectives are in conflict, as increased power density reduces life and ...

Both acoustic and electromagnetic waves exert forces of radiation on targets in their path of propagation. The radiation force (pressure) results from the change in wave momentum due to scattering by the target, averaged over one period of oscillation.  Modulated radiation pressure (MRP) utilizes the acoustic radiation force by using a double-sided suppressed carrier modulated (DSB-SCM) incident ...

Seatrec will collaborate with a team from the Woods Hole Oceanographic Institution to demonstrate the technical feasibility and commercial applicability of a novel energy harvesting system that converts thermal energy from high-latitude air-sea temperature differences into electricity.  This capability will extend the endurance and capability of observing system elements, reduce battery waste, a ...

We propose a suite of video processing algorithms utilizing the machine learning (ML) techniques of artificial intelligence (AI) reinforcement learning, deep learning, and transfer learning to process submarine imagery obtained by means of periscope cameras. Machine learning (ML) can help in addressing the challenge of human failure of assessing the data of periscope imagery. Though pre-tuned blac ...

Quantum Cascade Lasers (QCLs) are one of the most versatile sources of radiation in the mid-infrared range and have found applications in a variety of fields. Despite their widespread adoption, one of the main hurdles holding QCLs back from large volume manufacturing is the large cost of ownership. While QCLs, like most semiconductor devices based on III-V compounds, can leverage the economies of ...

Active Flow Control (AFC) systems require a compressed air source.  Candent is proposing to use its extensive turbomachinery experience and technology to design a high efficiency air compressor with proper flow and pressure ratio to meet the STTR requirements, including expected operational environments (ambient air temperature and pressure, sand and dirt). Candent will utilize its advanced compr ...

In the proposed STTR study, Catto Propellers, Inc. (Catto) and the University of North Dakota (UND) will create an efficient new propeller design utilizing advanced composite materials for use on small unmanned x systems.  During Phase I, a comprehensive study will be conducted to develop a new propeller design in order to increase propeller efficiency, reduce aerodynamic noise and utilize innova ...

Intelligent Optical Systems, Inc., in collaboration with Bowling Green State University, proposes to develop a field-rugged, eye-readable indicating spray solution that can immediately detect synthetic opioids over a large area of contamination (i.e., military vehicles, individual protective equipment, clandestine labs, etc.). The proposed chemosensor in a spray solution format will detect multipl ...
