Single-color MWIR LED arrays have made steady progress in demonstrating good performance, operability, efficiency, and reliability. On the other hand, dual-color MWIR LED arrays are highly desirable for testing dual color sensors. Compared to the optical combining approach, native dual-color LED arrays offer many benefits, including reduced system size and simpler optical system design. The propos ...

Using Combustion Research’ Flowfield Module (FM) approach, the Phase I effort laid the groundwork for the Hypersonic Vehicle Flowfield Module (HVFM) for axisymmetric/two-dimensional powered hypersonic missiles. As with all our FM tools, HVFM has an Intelligent Automated Architecture (IAA) agent which controls all aspects of the high-fidelity simulation pipeline allowing for non-experts in comput ...

The project objective is to greatly reduce the cost of monitoring soil water content in highly-resolved vertical profile to promote increased adoption of more efficient water management tools. Cost is the most significant barrier to adoption of sophisticated data-driven irrigation management in permanent agriculture. Highly-resolved vertical soil water profiles are needed to learn soil-specific hy ...

NDT of Fracture Toughness for Pipeline Steels3/16/2018Ultrasound-based technology to nondestructively determine fracture toughness of pipeline steels will be developed. Fracture toughness is the material parameter that, along with applied loading and flaw geometry, dictates the critical crack size, and therefore controls the flaw size that must be detected during inspections. A major challenge fac ...

Tragically, 936 children have died in hot cars since 1998. Wisely, NHTSA has prioritized evaluation of sensor systems in vehicles for “the ability to detect unattended children and prevent heat stroke occurrence.”Recently, innovators have developed systems that detect children present in the vehicle by measuring carbon dioxide (CO2) in the vehicle cabin, but there is no test method to assess w ...

The goal of the proposed project is to develop an innovative advanced Electrodynamic Vertical Gradient Freeze (VEDGF) crystal growth system with superior performance, versatility, stability, and longevity to produce large single-crystal CdZnTe wafers for long-wave infrared detector arrays. The project is aiming to develop an advanced VEDGF system that offers the following performance and capabilit ...

Our unique position allows us to begin assessing models for hypersonic flow prediction on real-world systems and immediately begin to develop tools that will support acquisition, tracking, and trajectory prediction for hypersonic cruise missiles (HCMs) accomplished largely through signatures electro optical/infrared (EO/IR), radio frequency (RF), radar cross section (RCS) and acoustic. For the Pha ...

The proposed solution is to develop an infrared light emitting diode (LED) scene projector and the associated system components that shall meet the DoD scene projection requirements and specifications. The unique feature of the proposed solution is the demonstration of a dual-band projector with record-breaking resolution and frame-rate of 2K x 2K x 1KHz for full-frame moving image projection. For ...

MAX phase materials are metallic ceramics known for combining favorable mechanical properties (such as good machinability and high elastic moduli) with good thermal shock resistance, low thermal expansion coefficients, and rigidity at elevated temperatures. In general, the MAX phases are a class of material consisting of a combination of three types of elements: M (an early transition metal), A (a ...

This SBIR effort proposes using live and continuous monitoring of metal tanks, pressure vessels, and pipelines using carbon nanomaterial-based sensing skins to detect excessive physical strains, cracks, and to inspect impact damage. The proposed research and development work leverages 15+ years of fundamental research. The key objective is to advance the TRL level and the scalability of carbon nan ...
