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 ...

The rapid advancement of microelectronics requires equivalently sized energy storage devices to provide energy for microelectromechanical system (MEMS) devices and other technologies. By using a novel approach to fabricate carbon nanotubes (CNTs), our electrodes have a high surface area with an aerial tube density up to 1,000 times greater than typical carpet-grown CNTs. By combining these electro ...

Designing an efficient and effective film cooling system to protect critical components of modern rocket engines requires a significant number of problems and challenges to be addressed. Complicating the already difficult hydrodynamic challenges, thermal and/or catalytic cracking of hydrocarbon fuels is always accompanied with coke formation. Coke deposits on combustor and nozzle walls reduce heat ...

Compact Electromagnetic Pulse Module (EMP) capable of being arranged in series-parallel planar or cylindrical arrays is needed to simulate nuclear weapon effects. High gain optically triggered photoconductive semiconductor switches (PCSS) based on Gallium arsenide (GaAs) with low timing jitter enables the development of planar or phased arrays of modular EMP or High Power Microwave (HPM) sources. ...

In this Phase II program, Voxtel will design, manufacture, and benchmark-test additive-manufactured (AM) insulators capable of electrical stress greater than 25 kV/mm, for use in high-electric-field applications, such as high-power microwave (HPM) devices. These insulators will sustain vacuum of 10-7 Torr and withstand 20 psi of pressure. To achieve this goal, Voxtel will synthesize readily additi ...

This Phase II STTR proposal will develop a computational tool for state-of-the-art computational modeling of multi-scale thermo-mechanics of heterogeneous energetic materials. The proposal will bring together researchers with long-standing expertise in flow software and physical modeling of high-speed reactive multi-material flows to work on further developing a cutting-edge computing tool called ...

Structural energetic materials or multifunctional energetic materials offer the ability to combine the high energy release rates of traditionalhigh explosives with structural strength. When successfully formulated therefore they can lead to light-weight, high-performance and hithertoinaccessible designs of munitions. The key feature of structural energetic materials (SEMs), perhaps even more so th ...

BioMojo LLC and the Departments of Mathematics and Biomedical Engineering at the University of North Carolina Chapel Hill, will develop a preliminary bio mathematical model framework to represent how human tissues interact and behave at their boundaries. Tissue interaction properties (e.g. tensile, shear, friction, and so forth) of connective, epithelial, muscular, and nervous tissue including su ...

Micro-RDC will develop portable radiation effects test structures that scales to new process nodes. These structures will enable the investigation of the effects of radiation on the new technology from the material processing level as well as the circuit level. The production of the chosen structures and the development of software to extract the model parameters will form the framework. A suit ...

Scramjet engines are designed to operate across a wide Mach number range and typically incorporate isolator sections to provide sufficient back-pressure margin and prevent unstart. As military requirements become increasingly demanding, an active, closed-loop control system is necessary to maintain engine stability and power output. During Phase I, key components of a scramjet control system were ...
