ABSTRACT: We propose build Infrared LED (IRLED) scene projectors that are able to project larger than 1k by 1k imagery with maximum temperatures of 3000K, frame rates in excess of 400 Hz, and emission wavelength between 3-5 microns. We will explore the use of through-silicon-via (TSV) and silicon interposer packaging technologies to achieve that goal. We will also evaluate the performance and cos ...

In this SBIR effort we will develop and analyze (Phase I) a new design and packaging approach for an ultra-compact, dual-output wideband Mach-Zehnder modulator (MZM) for low noise figure (NF) and high dynamic range radio-frequency (RF) photonic link applications. We will provide (Phase I) experimental proof-of-concept of the proposed device by tailoring our current 100GHz MZM product. In Phase II, ...

ABSTRACT: The damage tolerance approach is used widely in aerospace industry and has a physics-based foundation in fracture mechanics. The fatigue crack growth rate can be determined by calculating the SIF and knowing empirically derived material parameters. Similitude is achieved for different loads, different crack sizes, and different crack shapes. The down side to fracture mechanics is that a ...

Solid oxide fuel cells have long suffered from degradation due to impurities in the fuel and complexities associated with dissimilar materials and high operating temperatures. This degradation lowers the usable cell power output and requires ancillary equipment for fuel sulfur removal and reformation. A unique microstructure for the tubular anode will be produced using a novel freeze-casting tec ...

S-RAM Dynamics (S-RAM) will design, fabricate, test and commercialize a transcritical CO2 refrigeration system using the recently invented S-RAM CO2 oil-less, integrated expander/compressor unit (ECU). This CO2 refrigeration system will be targeted for mobile military cold storage assets and commercial transportation refrigeration units. The refrigeration system will meet the specified space requi ...

The potential for solid fuel ramjets (SFRJ) has been demonstrated over the last 40 years. SRFJ"s have significantly higher impulse than rockets (Isp>1200 sec) making them a competitive solution for long range applications such as missiles, missile interceptors, high speed transport and space vehicle stages. Increasing the regression rate and the energy density of the fuel further improves the adva ...

In this proposal, AlphaSense, Inc. details the development of a fully integrated laser ultrasound visualization and laser ablation tool for corrosion identification, removal and cleaning. The key innovations of this proposal include the following: a) Hidden corrosion detections based on direct visualizations of the ultrasound propagation characteristics, b) Corrosion product removal using laser ab ...

This STTR Phase I proposal proposes to design and develop reactive filter media using nanofiber technology to capture corrosion inducing particulate matter present in coastal region air. The fibrous filter media will be functionalized using ion exchange chemistry which is known to react with salt ions. The media will be characterized for its filtration performance, resistance to airflow, and dus ...
