Additive manufacturing (AM) is a very promising technique for rapid, low-cost production of aircraft parts directly from a CAD file. AM is especially appealing for complex parts that would be costly or impossible to fabricate by machining or casting. At the current time there are no reliable, cost-effective techniques to qualify the finished parts. Several government studies have noted this gap an ...

The Department of the Navy has a need for the development of an additive manufacturing (AM) process for key vacuum electronic device components to meet on-demand, flexible, and affordable manufacturing requirements. The developed manufacturing method has a potential to reduce cost of vacuum electronics by as much as 70% as well as simplify and hence expedite production process of these devices by ...

Systems that operate in constrained environments depend on the acoustics in several ways. Harbor defense systems detect intruders (people and/or vessels) by either listening for their noises (passively) or by pinging on them and detecting their echoes (actively). Furthermore, such systems may also form the equivalent of an underwater cell phone network using sound to carry the information. The aco ...

The Navy seeks new energetic and oxidizing ingredients for use in propellant and explosive formulations of modern weapons systems. With recent developments in the design and synthesis of new energetic molecules, we have the opportunity to take the steps needed before these materials can successfully transition to use in next generation propulsion and ordnance systems. TDA Research and the Universi ...

We are proposing to identify an ICME architecture that will enable the multi-scale modeling of additive manufacturing (AM) process at both the component level as well as at the meso-scale level such that the final part quality and performance can be predicted accurately. At the component level, the proposed ICME framework would help in predicting residual stresses, distortion and the necessary sup ...

High power switching devices are needed for all manner of weapon and defense systems as well as commercial power intense applications. Monoclinic beta()-Ga2O3 is an attractive material for power devices and is in its infancy with respect to development. It has the advantage of having large area economical substrates for device production. We have multiple early stage fielded tools and an in-house ...

SA Photonics is pleased to propose the SOCRATES free space optical communication and sensing system featuring the Photonic Optical Multicast Mast Unit (POMMU). SOCRATES enables 360 degree multicast capability of high bandwidth communication in addition threat search and track capability. SA Photonics will team with the Prof. Michal Lipson of the Lipson Nanophotonics Group at Columbia University wh ...

Prof. Diezs group at Rutgers University has developed a small platform for an unmanned aerial and submersible system that it is capable of operating in air and underwater with seamless transition between both mediums. This small platform is currently being optimized by his group for improved (1) control and (2) robustness, and it will be incorporating capabilities to it include (3) communication a ...

Using a fluid dynamic energy separation technique, in combination with thermoelectric generators (TEGs), a unique hybrid cooling system using low grade waste heat is proposed. This system uses the concept of fluid structure interactions and vorticity redistribution to produce large levels of vorticity within working fluid and thereby generate large temperature gradients in the working fluid which ...

As Navy combat systems evolve, the heat loads produced by electronics enclosures continues to increase. Legacy thermal management techniques for these enclosures such as liquid cooling coupled to the ship chilled water supply and direct air cooling of the cabinets require infrastructure such as pipes and ducts which are expensive to install and reconfigure. Mainstream proposes to design a vapor co ...
