A proposed acoustic pattern recognition system will be based around an array of acoustic sensors to allow localization of sound events and cancellation of background noise. The number of sensors could be adjusted to vary the coverage area depending on the site. The measured signals will provide the input to a sophisticated signal processing algorithm that will separate the acoustic signals into ...

The problem is to improve airborne maritime radar detection of small moving targets in clutter, where the clutter varies with time, range, azimuth, sea state, grazing angle, wind speed, and the look direction of the radar relative to the wind direction. A new version of space-time adaptive processing (STAP) is applied to the problem. The new technique provides improved covariance estimation for ...

The Department of the Navy has a need for the development of an additive manufacturing (AM) process for key vacuum electronic device components to meet on-demand, flexible, and affordable manufacturing requirements. The developed manufacturing method has a potential to reduce cost of vacuum electronics by as much as 70% as well as simplify and hence expedite production process of these devices by ...

The Navy is currently developing advanced surface combatants like DD(X), LPD-17, LCS and CVX to meet challenges of the 21st century. The desire to reduce maintenance cost and weight makes the use of composite structures very attractive, but cost of manufacturing large composite structures remains a significant technology barrier. KaZaK and UMass Lowell propose to develop pultrusion technology of b ...

Under this STTR solicitation N20B-T028, the goal is to build on the strengths of HyPerComp’s development in the HDphysics suite of tools to meet NAVAIR’s requirements in solving large-scale problems in electromagnetics.  One area that will receive a major attention in this effort is the development of high order curved meshes for arbitrary geometries with small- and large-scale features that ...

During the NAVY STTR Phase II Calnetix will further develop its concept of advanced flywheel system proposed in Phase I and will demonstrate the validity of the underlying principles through building and testing a system prototype. This prototype will be a fully functional system capable of supporting up to 2MW of pulse power with the ability of producing 500kW (30 seconds) loads in high-duty-cyc ...

In hypersonic flight, airborne particles such as water or ice can penetrate and alter the bow shock and flow field, enhance erosion mechanisms and alter aerodynamics. Particles break up as they pass through the shock wave, impact the surface, erode and increase surface roughness, increase turbulence and heat transfer, and augment heating that can destroy heat shields prematurely. Many tests and th ...

The purpose of this project is to demonstrate the feasibility of using an innovative, durable, low friction, and non-toxic solid lubricant coating for foil air bearings for air cycle machines (ACM). Acrees coating provides superior wear characteristics at all temperatures and provides a substantial improvement over polyimide type coatings that are currently used on ACMs. The coating consists of tw ...

In this proposed SBIR program, IBC Materials & Technologies, in conjunction with our industry partner Mechanical Solutions, Inc. (MSI) and Texas A&M University, will leverage our knowledge and experience in the domain of industrial metallic coatings to develop a metallurgical coating solution for the Air Foil Bearing. IBC has deep expertise in a variety of industrial coating processes including mu ...

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 ...
