Traditional manufacturing methods for producing warheads, propellants, and pyrotechnic systems are timely and costly. Additive manufacturing (AM) approaches offer one path of alternative manufacturing technologies. Among various technologies, powder bed fusion (PBF) is one promising approach. Hewlett Packards Multi-Jet Fusion printers utilize a unique PBF process that presents a desirable solution ...

The overall and principal objective in the Phase I effort will be determining the feasibility of an algorithmic approach to yield reliable and reduced target AOUs in an air deployed multi-static active sonar field. The feasibility will be based on the realized accuracy gains; achieving real-time data turn-around; and the computer information processing (IP) resources needed for estimating AOUs in ...

A need exists to improve the ballistic response of armor for Littoral Combat Ships. Simply increasing armor thickness is unacceptable because the associated increase in weight and space would reduce vessel performance speed and range. Surface treatment techniques for current armor materials such as steel, aluminum and ceramic may improve armor performance significantly without an associated weight ...

Eagle Harbor Technologies, Inc. (EHT) is collaborating with researchers at the Pulsed Power and Power Electronics Center at Texas Tech University (TTU) to develop a high-power microwave switch that is capable of very fast rise times, adjustable pulse width, and high pulse repetition frequency (PRF). EHT has developed solid-state pulsed power systems that has the potential to improve the performanc ...

Advances in semiconductor technologies, including Gallium nitride (GaN) and Silicon carbide (SiC), are allowing for the wider use of solid-state devices in modern radar systems. These devices include direct digital synthesizers and their associated memories, i.e. numerical look up tables for reprogrammable radar parameters, as well as solid-state power amplifiers (SSPA). Since solid-state systems ...

In an effort to development more robust optical system coatings DTRA, in collaboration with Sandia National Labs, is working to characterize the degradation of optical materials for space systems when exposed to high intensely EUV/ cold x-rays. The experiments utilizes the Double Eagle z-pinch facility which generates high current, high voltage arc pinch plasma to produce an intense EUV and cold x ...

Traditional weapon systems often fail to meet the requirements of close combat typical of the previously discussed engagement, where insurgents often blend in or store weapon amongst friendly or non-combatant forces, to shield them from precision strike munitions of a technologically superior force. This type of warfare has led to an increased focus on the use of less-lethal weapons, to reduce let ...

Integration of the sailor into the Navy’s system of systems onboard ship and off will enable improvements to the availability of mission-critical information to both the sailor and the Command. This integration is to be accomplished through embedding electronic system functionality into the sailor’s uniform, enabling what Propel has named the Smart Integrated Uniform™(SIU). Through selective ...

There are numerous conditions where gas turbine engines ingest small particulates. Of particular concern are the particles (~1-10 micrometer) that are ejected into the atmosphere as volcanic ash. Ingestion of these particles has numerous detrimental effects. Particle collisions cause abrasion of compressor blades, leading to loss of efficiency. Ingested particles that partially or completely melt ...

A very fast 1xN optical switch capable of handling high-optical power is proposed. It is designed for switching laser power from a central source to multiple outputs using photonic switch technology that does not have any mechanical moving parts. It is designed to have a very compact size and high-reliability operation suitable for airborne environment. The switching speed will be >10 W of optical ...
