Parametric Analysis of Various Test Configurations for Measuring the Interlaminar Fracture Toughness of CMCs using LayerSlayer and AbaqusSBC: AURORA FLIGHT SCIENCES CORPORATION Topic: N13AT008
The low weight, excellent durability and heat resistance of ceramic matrix composites (CMCs) make them attractive materials for use in aircraft engine hot sections, where improved overall engine efficiency can be realized. Nevertheless, the interlaminar properties of CMCs must be well understood before CMCs can realistically replace metallic superalloys in engine hot sections, and no standardized ...STTR Phase I 2013 Department of DefenseNavy
A universal framework for non-deteriorating time-domain numerical algorithms in Maxwell's electrodynamicsSBC: COMPUTATIONAL SCIENCES LLC Topic: A13AT008
The project will remove a key difficulty that currently hampers many existing methods for computing unsteady electromagnetic waves on unbounded regions. Numerical accuracy and/or stability may deteriorate over long times due to the treatment of artificial outer boundaries. We propose to develop a universal algorithm and software that will correct this problem by employing the Huygens'principl ...STTR Phase I 2013 Department of DefenseArmy
SBC: Sciperio, Inc. Topic: A13AT010
Sciperio with team members Georgia Institute of Technology and Centecorp have teamed up to develop an Additive Manufacturing Composite using nano and micro fillers. The team will develop multi-scale models that are supported by experimental characterization for advanced 3D Printable materials. Inelastic response of high strength hierarchical structures composed of engineered materials and specif ...STTR Phase I 2013 Department of DefenseArmy
SBC: RADIATION MONITORING DEVICES, INC. Topic: A13AT013
The goal of the proposed program is to identify an effective passivation material and develop a capable passivation methodology to protect highly reticulated HgCdTe surfaces. The proposed passivation material and technique using highly conformal atomic layer deposition (ALD) will allow the DOD to develop high-performance infrared focal plane array detectors that can operate under wider operating c ...STTR Phase I 2013 Department of DefenseArmy
SBC: Aegis Technologies Group, LLC, The Topic: AF18BT003
Electronically dimmable materials with sufficiently strong visible transmission shift, color neutrality, durability and switching speeds have eluded development since the search began nearly half a century ago. We demonstrate the potential for dynamic optical dimming using plasmonic nanostructures with electrodynamic simulations of promising plasmonic metamaterial architectures. In order to achiev ...STTR Phase I 2019 Department of DefenseAir Force
SBC: METIS DESIGN CORP Topic: AF18BT006
The computing demands of future data-intensive applications far exceed the capabilities of todayâ€™s electronics and cannot be met by isolated improvements in transistor technologies or integrated circuit (IC) architectures alone. Carbon Nanotube Field-Effect Transistors (CNFET) technology has emerged as leading candidate for energy-efficient and high-performance digital systems. Unfortunatel ...STTR Phase I 2019 Department of DefenseAir Force
SBC: CHARLES RIVER ANALYTICS, INC. Topic: AF18BT007
Improved cameras and unmanned air vehicles (UAVs) have led to an explosion in the amount of airborne imagery and video collected by Air Force assets, but there are not enough trained personnel to analyze this imagery in real time. Thus, targets of opportunity and threats go undetected until the chance to act on them has passed. Automatic target detection could alleviate the burden on analysts and ...STTR Phase I 2019 Department of DefenseAir Force
SBC: NEVADA NANOTECH SYSTEMS, INC. Topic: AF18BT009
Proposed herein are novel design methodologies to create sensors for chemical, biological, radiological, nuclear and/or explosive (CBRNE) detection aboard a Small Unmanned Aerial System (SUAS), as well as intelligent Bayesian-based plume analysis and source detection algorithms that offer capabilities for the Air Force above and beyond the state of the art. The assembled technical team of experts ...STTR Phase I 2019 Department of DefenseAir Force
SBC: STREAMLINE NUMERICS INC Topic: AF18BT010
The objective is to develop zonal multi-physics capability for turbulent combustion simulations. The foundation of the proposed work is a novel Pareto-Efficient Combustion (PEC) framework for fidelity-adaptive combustion modeling. The PEC model utilizes a combustion submodel assignment, combining the low-cost flamelet-based models with the more expensive finite rate chemistry models where necessar ...STTR Phase I 2019 Department of DefenseAir Force
SBC: RADIATION MONITORING DEVICES, INC. Topic: AF18BT014
Measuring the response of explosives to a variety of thermal and mechanical inputs is important to understand and ultimately predict the reaction violence of an explosive in an accident scenario. Technically, there are many challenges to overcome in observing explosives response. For instance, secondary high explosives are heterogeneous and optically opaque and often need to be confined in metal c ...STTR Phase I 2019 Department of DefenseAir Force
