The objective of proposed research is to demonstrate and validate a prototype of an Integrated Computational Materials Engineering (ICME) predictive modeling tool to fine-tune Gas Flow (G) and associated parameters for Metal Fusion (M) to attain high-quality AM Process-Structure-Performance (PSP). Validate Additive Manufacturing (AM) part quality using Directed Energy Deposition (DED) to repair ga ...

To attain the goal of the Topic which is to develop a digital design tool for PPE that allows for rapid exploration of the entire design space, Innovision team has proposed and been developing an innovative solution—Integrated Digital Engineering Environment for PPE development (IDEEP), which consists of six modules: (a) Initial design, which creates a set of design instances in the design space ...

Machine learning algorithms have demonstrated performance on par with or superior to human analysts on large datasets when sufficient training data is available.  For military applications obtaining sufficient, truthed data is always a challenge.  Three approaches have been used for measured data collections to support sensor exploitation programs: coordinated collections, turntable measurements ...

Bio-inspired swimming robots have shown promise in a wide range of applications due to their efficiency, speed, and stealth capability. To prepare our workforce for the Uncrewed Underwater Vehicles (UUV) technologies of tomorrow, we need to ensure that unique aspects of bio-inspired Navy specific robots—soft actuators, flexible materials, waterproofing, sensing/controls, periodic motion—are in ...

SK Infrared, in collaboration with subject matter experts from Ohio State University (OSU) is proposing to develop inexpensive LiDAR-like 3D imaging sensors with high depth and vertical resolution and a large field of view (FOV). The 3D Multimodal Imaging with LiDAR-like Engineered Sensor (3D-MILES) will be a novel product that can be used for reliable object detection at medium to long ranges in ...

Hydrometeors consisting of liquid water droplets or solid particles of ice can disrupt the boundary layer near hypersonic vehicles, and ultimately impinge on the surface causing surface roughness and further altering the flowfield. To advance the knowledge of hydrometeors and their impact on hypersonic flight, it is critical, therefore, to develop practical, high-fidelity and spatio-temporally res ...

In order to achieve the best possible performance in additively manufactured components, design of new alloys that are tailored to the unique thermomechanical history of additive manufacturing is necessary. It is well known that the fast cooling rates associated with additive manufacturing can produce unique microstructures not seen in conventional processing of many alloys. Rapid alloy design com ...

The Defense Threat Reduction Agency (DTRA) needs a capability to collect and provide immediate presumptive analysis of radiological/nuclear samples of concern at the source of collection. Such in-field technologies should be capable of detecting and identifying trace quantities of elements and/or chemicals containing plutonium (Pu) and uranium (U), with a focus on chemicals specific to the nuclear ...

Combustion instabilities and secondary wave systems can affect the detonation wave(s) in a rotating detonation combustor (RDC) for augmentors and lead to reduced combustion and thermodynamic efficiencies. To improve the performance of RDCs, it is critical, therefore, to develop practical and robust passive suppression technology to mitigate these acoustic and secondary wave systems. A goal of t ...

The utilization of additive manufacturing for fatigue rated components is severely hampered by the lack of accurate tools for prediction of fatigue life in additively manufactured parts as a function of material, microstructure, residual stresses, defects, etc that arise as part of the AM process. In the proposed effort, MRL will build on the fatigue modeling tools demonstrated in Phase I to demon ...
