An Immersed Boundary Framework for Topology Optimization of Nonlinear Thermoelastic Structures with Internal RadiationSBC: SPECTRAL ENERGIES LLC Topic: AF17AT015
Thermoelastic structures poses a critical challenge to designers due to the inherent proportionality of the thermal loading on the structural thickness. This is further exacerbated by structural nonlinearity where any out-of-plane deformation further increases the effective loading on the structure. As a result of this, conventional design optimization procedures, which are typically based on line ...STTR Phase I 2017 Department of DefenseAir Force

Improved temperature measurements of thermal barrier coating (TBC) components are needed for gas turbine research and development.Imaging pyrometry systems are preferred because they are non-contact and can measure the complex spatial temperature distribution on components.Measurement in the long-wave infrared (LWIR) band is required for accurate temperature measurements of modern TBCs.Fiber coupl ...STTR Phase I 2017 Department of DefenseAir Force
SBC: SPECTRAL ENERGIES LLC Topic: AF17AT020
The overall goal of the proposed research program is to design a ruggedized imaging system capable of visualization and analysis of the particle field and product gases in a multiphase blast. This will be accomplished by combining kHz-MHz-rate burst-mode laser technology with tomographic particle image velocimetry (PIV) and new nonlinear particle tracking methods to resolve dense particle fields. ...STTR Phase I 2017 Department of DefenseAir Force
SBC: BOULDER NONLINEAR SYSTEMS, INC. Topic: AF17AT021
In partnership with the Strausfeld Lab at the University of Arizona, BNS proposes to develop an Amplitude and Polarization High-speed Image Display (APHID) based on our previous VIS/NIR Hyperspectral Image Projector (HIP) design. Using BNS-developed liquid crystal (LC) spatial light modulators (SLMs), this display will provide high-speed multispectral wide-field visual stimulus to invertebrates ov ...STTR Phase I 2017 Department of DefenseAir Force
SBC: TRUVENTIC LLC Topic: AF17AT022
Truventic proposes a novel MEMS-based plasmonic infrared scene projector to support hardware-in-the-loop testing of missile seekers, forward looking IR cameras (FLIR), counter measure simulation and tracking systems. The approach avoids known limitations of resistive arrays and provides high dynamic range, unprecedented high apparent temperature, high modulation rates, high pixel to pixel contrast ...STTR Phase I 2017 Department of DefenseAir Force
SBC: PLASMONICS INC Topic: AF17AT022
As both the response speed and sensitivity of thermal imagers have improved significantly over recent years, new IRSP systems are needed to provide greater dynamic range and faster response speeds. Addressing these issues, as well as producing a cost effective and modular IRSP system will be critical for providing quality scene projection for the next generation of infrared imagers. To address the ...STTR Phase I 2017 Department of DefenseAir Force
Extending Molecular Simulation to Grain Scale for Simulating Response of Energetic Material Under High Strain Rate and Shock LoadingSBC: CFD RESEARCH CORPORATION Topic: AF17AT023
High Velocity Penetrator Weapons experience severe stress in terms of high frequency vibration and shock during launch, flight, and on impact. The extreme conditions have significant impact on the survivability of the weapon due to damage of the energetic material and fuze compartment. Molecular dynamics is often used to understand the effect of external shock on the material. However, molecular ...STTR Phase I 2017 Department of DefenseAir Force
SBC: INTERDISCIPLINARY CONSULTING CORP Topic: AF17AT003
The Interdisciplinary Consulting Corporation (IC2) in partnership with the University of Florida, proposes to develop and standardize a novel, high-frequency dynamic pressure sensor calibration method and system for sensors used in the measurement of high speed flows. The proposed innovation is a novel calibration method combined with modified and repurposed measurement hardware to enable calibra ...STTR Phase I 2017 Department of DefenseAir Force
SBC: CREARE LLC Topic: A17AT022
Blast-induced Traumatic Brain Injury (TBI) is a major threat to the health of military personnel serving in modern theaters. As such, the biomechanical injury pathways of TBI are and have been the focus of many animal studies. However, differences in the experimental setups across laboratories make it difficult to draw definitive conclusions from the resulting data. A tool that can accurately e ...STTR Phase I 2017 Department of DefenseDefense Health Agency

High speed air vehicles, already operating at material strength performance limits, are at significant risk when subjected to additional localized heating from sources such as directed energy. This localized heating may result in material softening, pitting and burn through causing structural damage and alteration of the structural profile. This damage can disrupt the aerodynamic performance and ...STTR Phase I 2017 Department of DefenseAir Force
