Naval aircraft components are routinely made of 7000 series aluminum alloys due to their strength, weight and fatigue properties. Present Additive Manufacturing (AM) processes fall short of producing 7000 series Al alloys successfully due to lack of porosity, and thermal and composition control. In-situ methods implemented to date largely only yield information about the component surface and othe ...

There are currently no vaccines or therapeutics available for Marburg Virus Disease (MVD). Given the specter of weaponization and the terrible morbidity and high mortality rate of MVD, this represents a critical threat to the operational readiness of the Warfighter. While traditional vaccines have contributed greatly to public health, they have some limitations especially in the context of operati ...

The Phase 2 development will yield a prototype Cognitive Data Sampling (CDS) system for 2 RF bands to fully demonstrate the capability of the underlying technology. This will include the development of RF antennas, RF signal conditioning for the bands, CDS analog to conversion module and a processor module. The processor module shall be comprised of a Commercial Off-The-Shelf (COTS) module that in ...

Current design tools for gas turbine engines invoke a variety of simplifying assumptions to estimate heat transfer to solid/metal engine components (e.g., isothermal boundary conditions). These approximations are often not valid, result in inaccurate predictions of heat transfer, and ultimately compromise the thermal integrity of propulsion and power systems. Wall-modeled large eddy simulation (WM ...

Vadum proposes to mature its Vibration-Enhanced Underground Sensing (VENUS) technology into a reliable, shallow-buried low-metal-content landmine discrimination and classification solution with minimal False Alarm Rate (FAR).  VENUS exploits a novel vibration phenomenology to provide unique discriminatory information and estimated classification of the buried target that enhances and complements ...

Hypersonic systems travelling above the speed of Mach 5 impart intense thermal stress on the airframe, requiring the use of refractory alloys to withstand the heat. The leading edges of hypersonic airframes and scramjet engine intakes are required to be sharp, smooth, and highly accurate to reduce drag and prevent unwanted shock waves due to manufacturing errors. Additionally, rocket engines, both ...

The proposed project will develop subject-specific FE models of the head and integrate them with a full body finite element model. The combination of patient-specific head geometries with the generalized body model will provide a platform with which to apply improved boundary conditions for the head and neck, including applied muscle tension and the application of appropriate kinematics of the hea ...

Carbon-carbon (C-C) composites are used in the fabrication of aeroshells and thermal protection systems (TPS) in hypersonic and atmospheric reentry applications because they maintain their strength at elevated temperatures and have desirable thermal conductivity properties. Although these materials have been used in mission-critical components for decades, the effects of variations in processing m ...

OLGS is developing an automated tourniquet system. It is an intuitive device that works with the push of a button. The user only needs to know 'high-and-tight' and push the button for the tourniquet to be effective. It contains a band with wires embedded that is tightened by a motor-driven spool. It also contains a micro-controller unit with integrated sensors to ensure limb occlusion pressure is ...

The performance of a composite material is heavily influenced by the strength and toughness of the interlaminar region, which is the resin rich area between the plies of a fiber reinforced composite.  The interlaminar region generally provides a direct path for crack propagation since no continuous reinforcement is present and is often the cause of failure in materials subjected to cyclic loadin ...
