Evolving demand for robust and accurate multi-physics modeling tools for high performance combustion devices is being driven by increasingly complex design, analysis, and simulation requirements, but existing models and their underlying assumptions need to be rigorously examined in light of their intended Air Force propulsion system applications. The production use of coupled multi-physics module ...

MicroLink Devices has developed, and is currently producing, thin epitaxial lift-off inverted metamorphic solar cells for flexible solar sheets using a four-inch GaAs wafer platform. These cells have been demonstrated in a variety of applications including panels attached to Marines"backpacks and the wings of Raven and Puma unmanned aerial vehicles (UAVs). Although good system performance has su ...

ABSTRACT: This Small Business Innovation Research (SBIR) Phase I project proposes to develop and demonstrate a test apparatus for determining the minimum hot surface ignition (HSI) temperature of flammable liquids. Flammable liquids leaking onto hot surfaces, such as those in an aircraft engine bay, present fire hazards. To properly assess and mitigate these hazards, an in depth knowledge of th ...

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 ...

High performance steels were developed in a cooperative program between the Federal Highway Administration (FHA), the American Iron and Steel Institute (AISI), and the U.S. Navy Carderock Division of the Naval Surface Warfare Center. HPS70W high strength steel is currently being used in bridge structures. HPS is stronger than conventional 70W steel and has less than 15% of the sulfur and 60% of th ...

Mild traumatic brain injury (mTBI) is a common result of military engagements and training. One of the most difficult issues in treating mTBI is diagnosing the presence of mTBI and evaluating its severity. Studies have shown that balance disorders are a common symptom of mTBI and can occur in up to 95% of individuals. Existing types of balance testing are not adequate to assess a vestibular disor ...

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 ...

Conventional CFAR detection processing has difficulty in heterogeneous clutter (i.e., maritime clutter) because the fixed data size windowing is not well matched to the spatial scales of the wave field over a wide range of sea states. The non-Gaussian nature of heterogeneous clutter gives rise to significant spatially varying CFAR loss to maintain low false alarms that desensitize the radar in str ...

Dense maritime environments pose significant challenges to naval airborne maritime sensor systems with respect to surface target classification because surface vessels of interest must often be separated from a larger number of similar looking surface vessels with non-threatening intent. Perhaps the most difficult classification challenge arises in vessels that are inherently similar in nature and ...

Proposed effort will formulate and demonstrate the methodology for fabricating Porous Ceramic Matrix Composite (PCMC) transpiration plates with controlled levels of porosity, suitable for high-speed/high-temperature missile applications.Process will entail subjecting polymer composites to high-temperature pyrolysisprocess converting it to a porous ceramic matrix and locking the fiber reinforcement ...
