The XS-Air engine should provide the highest power density with both diesel and gasoline piston engines. This would be especially true in smaller engines in where turbos or blowers are impractical. The XS-Air engine can solve the aviation industry problem of the potential phasing out Av-gas. The spark ignition XS-Air engine should be able to burn pump gas and still generate extreme power densities ...

Understanding the installed performance of antennas and optimizing their placement on platforms is critical to achieving the expected operational performance of the RF systems they support. Installing antennas on aircraft degrades their performance relative to freestanding conditions in terms of field-of-view, raised sidelobes, introduction of multipath delayed signals, radome-induced beam shiftin ...

The proposed project will undertake the research, design, and development of key concepts and technologies for a high-speed electronically tunable channel filter, based on monolithically integrated ultra-high-resolution super-compact grating (UHR-SCG) technology that has been developed in OptoNet. The grating will be realized on Silicon-Photonic Electronic-Photonic Integrated (EPIC) Platform that ...

A notable failure mechanism in thermal barrier coatings (TBCs) is the attack by calcium-magnesium-alumino silicate (CMAS) deposits resulting from the ingestion of siliceous minerals with the intake of air. Existing TBC systems such as yittria partially stabilized zirconia (YSZ) are highly susceptible to CMAS infiltration. In this STTR program, QuesTek Innovations LLC, a leader in the field of comp ...

This SBIR phase-2.5 program is proposed to advance the state-of-the-art d36 shear mode projector which is the first known d36 underwater projector in the history of acoustic transduction devices. Phase II effort has shown significant advancements toward the d36 shear mode projectors in bandwidth and source level, especially its compact size. Ternary PIN-PMN-PT single crystals have been integrated ...

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 this proposal, a single chip solution is given which promises high power ou ...

Turbo-shaft engines operating in desert environments are continuously exposed to erosive media, such as sand particles. This environment leads to compressor airfoil erosion resulting in significant performance loss of the engine, reducing fleet readiness and increasing maintenance costs. Additionally, high-energy particle impact can introduce significant foreign-object damage (FOD) leading to airf ...

The so-called"software crisis"is continuing unabated. It is all too common for a software project to create software that is hard to maintain, inefficient, bug-ridden, late, and over-budget. Software flaws resulting from this current state of affairs are no longer an inconvenience but are the largest source of software security vulnerabilities. Motivated by a desire to increase our ability to ...

To support the Navy's requirements for low-noise magnetic sensing from small unmanned aerial vehicles (UAVs), we present effective methods for suppressing platform and external interferences. We propose to develop a comprehensive magnetic compensation system that heavily leverages a number of innovations, experience, and on-going work by our team. Our approach combines thorough characterizati ...

High-performance, stainless bearing steel is needed to achieve long life and efficient operation of aerospace drive system turbine machinery operating in a corrosive environment. Available aerospace gear alloys such as Pyrowear 53, 9310, and Ferrium C64 are not corrosion resistant. Other options may also provide some level of corrosion resistance, such as in Pyrowear 675, but, ultimately, corrosio ...
