To address U.S. Navy needs, Sentient proposes to establish a Design Framework for reliability assurance of additive manufactured (AM) parts using their DigitalCloneTM Component (DCC) software. The framework will be tailored to metal components built through AM processes with complex geometries. Sensors are embedded during AM component build to allow for exploitation of sensor data, physics-based m ...

Idaho Scientific proposes to design and develop, SPUD, an irrefutable tamper logging protocol.During the course of this Phase I effort, Idaho Scientific will implement the core of the logging protocol and develop a set of unit tests designed to evaluate properties of that protocol that uphold its irrefutable claims. During a Phase II effort, Idaho Scientific would propose to encapsulate this proto ...

Advanced Ceramic Fibers, LLC (ACF) completed the Navy SBIR Phase I Base Program and clearly demonstrated the feasibility of our approach to create a truly robust composite for turbine engines that exceeds the known boundaries for ceramic composites and the Navy performance objectives for this Topic. Our engineered materials approach involved in-depth background experience in ceramic matrix composi ...

Submarine applications for antennas are severely constricted by mission constraints for stealth and force protection. High fidelity fiber optic links could potentially open a new range of mission capabilities by enabling towed antenna arrays that could be accessed while submerged. However, to date RF photonic links have had insufficient noise performance and/or dynamic range to satisfy these missi ...

Modern computer systems often incorporate multiple computational devices such as conventional processors, graphics processing units (GPUs), specialized accelerators, and field-programmable gate arrays (FPGAs). Programmers are able to exploit these new architectures for improved performance and reduced power consumption, but at the cost of increased programing complexity. Further complicating matte ...

To reduce size, weight, power and cost (SWaP-c) military platforms have been evolving towards a more integrated design approach that efficiently utilizes all available space.To accommodate limited space constraints many commercial off-the-shelf (COTS) systems will need to be replaced by custom designed and fabricated components.For the case of radiofrequency (RF) electronic systems this will requi ...

A bore evacuator is generally used in gun barrel of armored fighting vehicles to help prevent poisonous propellant gases from venting back into the fighting compartment. It consists of a ring of holes drilled into the barrel, surrounded by a cylindrical pressure reservoir. Under typical operating conditions, pitting corrosions and stress corrosion cracks can form in the inner walls of those drille ...

Plasmonic metamaterials, composed of patterned metallic and dielectrics, can be engineered to have interesting optical properties that are attractive for a range of advanced obscurant applications. These particles are typically fabricated on planar surfaces, since patterning planar surfaces to achieve the desired effects is relatively straightforward.However, for planar geometries the particles op ...

ABSTRACT: Casting parts with intricate internal surfaces are routinely used in many gun systems. It is important to inspect those casting parts to ensure the inner structures comply with the original design during the first article testing and production lot certification. Currently, inspections of inner surfaces are often done with borescopes, which is time consuming, labor intensive, and costly. ...

ABSTRACT: The past decade has seen a proliferation of computing devices. A landscape once dominated by single core microprocessors has given way to a plethora of competing technologies including multicore x86, ARM, and Power-family processors, graphics processing units (GPUs), field-programmable gate arrays (FPGAs), Xeon Phis, DSPs, and TILE architectures, among others. Further complicating matter ...
