Infrared countermeasure and standoff chemical detection applications require a light source with high power output, good beam quality, and a wide tuning range. There are a limited number of viable mid-infrared (3-5 micron wavelength) solutions that can provide these features in a compact and power scalable architecture. In the proposed work, a single chip solution will be developed which will deli ...

Additive Manufacturing (AM) promises to be an innovative technology that can enable rapid manufacturing of complex parts at greatly reducedcycle time. With the maturation of selective laser melting (SLM) AM technologies there is increasing interest in applying this manufacturingmethod to the production of aircraft structural components, many of which are made of high-strength stainless steels. How ...

Existing TBC systems in aeroturbine engines, such as yittria partially-stabilized zirconia (YSZ), are highly susceptible to degradation by infiltrating molten deposits formed when calcium-magnesium-aluminosilicate (CMAS) particulates such as dust, sand, or volcanic ash are ingested into the engine. Assessing CMAS resistance of known TBCs for a wide variety of particulates (e.g. susceptibility of s ...

During Phase I of this project, WElkins identified, developed and established the technical merit of potential improvements to the SEAL Delivery Vehicle (SDV) Diver Human Thermal Interface (DHTI). In Phase II, we shall build prototypes of the next-generation DHTI, including a multi-zone Liquid Cooling Garment, Quick-Disconnect Coupling, and Fluid Delivery Lines. These prototypes will be tested in ...

Advances in semiconductor technologies, including Gallium nitride (GaN) and Silicon carbide (SiC), are allowing for the wider use of solid-state devices in modern radar systems. These devices include direct digital synthesizers and their associated memories, i.e. numerical look up tables for reprogrammable radar parameters, as well as solid-state power amplifiers (SSPA). Since solid-state systems ...

The Navys Fleet-Class Common Unmanned Surface Vessel (CUSV) demands associated subsystems function with robust reliability and minimal operator intervention in order to operate at peak effectiveness. Mine Warfares (MIW) inherently hazardous nature requires particular focus on reducing manning requirements and simplifying operator machine interface (OMI) in order to minimize danger to personnel. By ...

Additive Manufacturing (AM) promises to be an innovative technology that can enable rapid manufacturing of complex parts at greatly reduced cycle time. Application of this technology to the manufacture of aircraft structural components is limited by the lack of high-strength aluminum alloys optimized for AM processing. In this SBIR program, QuesTek Innovations, a leader in the field of integrated ...

Phase II of this SBIR research effort fosters the next step of introduction and application in the development of a bistatic capability for surface and submarine Mid-Frequency (MF) active sonar systems. This development will enhance anti-submarine warfare (ASW) capability in strike group or coordinated surface and submarine ASW operations. Phase II builds on progress made in Phase I to develop and ...

The Next Generation Equipment Committee (NGEC) developed a standard for specifying the use of an Ethernet based digital train line (DTL) network to replace the COMM line for passenger trains. These specifications are PRIIA 305‐919 Digital Train Line Hardware and PRIIA 305‐920 Digital Train Line Software. The intent Is to eventually allow for the improvement of passenger train control. DTL spec ...

Integration of the sailor into the Navys system of systems onboard ship and off will enable improvements to the availability of mission-critical information to both the sailor and the Command. This integration is to be accomplished through embedding electronic system functionality into the sailors uniform, enabling what Propel has named the Smart Integrated Uniform(SIU). Through selectively integr ...
