Exfoliation corrosion of 5XXX series aluminum alloy is an issue related to the sensitization of the aluminum substrate typically occurring at end-grains. The Navy is interested in preventing this corrosion to decrease lifetime costs on Littoral Combat Ships, Ship-to-Shore Connector vessels, and Ticonderoga class ships. Luna will investigate surface modification using laser surface melt processing ...

Alloys of aluminum in the 7000 series are known to have good weight, strength, and fatigue properties and are commonly used in Naval aircraft components. Recent manufacturing trends are increasingly focused on additive manufacturing (AM) methods as a way to reduce lead time, cost, and to improve part performance. Current additive manufacturing techniques are unable to fabricate parts in 7000 serie ...

Accurate oceanographic sensing of temperature, salinity, velocity, noise, and turbidity is important to broad scientific, commercial, and military applications. The subsurface environment directly affects animal migration, sonar propagation, global weather patterns, and the primary productivity that underlies the ocean food chain. Most current methods for subsurface sensing require stationing of a ...

The focus of our Intelligence and Intuition for Enhanced Decision Making (I2EDM) Phase 1 research is to provide efficient and timely automated production and dissemination of information products in support of doctrinal Decision Points for the Company and below in austere environments. Operating in the Cloud, I2EDM will continuously fuse tactical information with human intuition and experience to ...

Aurora Flight Sciences and MIT have been developing tools and techniques that, together with existing 3D environment decision-making and navigation tools developed by AMRDEC in the PALACE program, are well-suited to the problem of autonomous vertical landing on unprepared landing sites. In this program, Aurora will team with MIT researchers and UC Santa Cruz (UCSC licenses PALACE technologies for ...

The goal of this proposal is to develop a compact sensor package and monitoring protocol for detecting the degree of sensitization in 5xxx series alloys that accounts for lot-to-lot variability. 5xxx series aluminum alloys have been utilized in marine applications to reduce weight and lower the center of gravity of ships for many decades. While effective, they can become susceptible to intergranul ...

In miniature gas turbines for UAV applications, traditional bearings exhibit a typical lifetime of only 25 hours due to excessive axial loading. Mainstream proposes to use a passive, permanent magnet thrust bearing to alleviate this problem and increase service life to over 1000 hours. Since this type of bearing is non-contacting, it can operate at very high rotational speeds with minimal heat gen ...

We propose to further develop the phase-field modeling and simulations we carried out in Phase I. Key focus of our research effort are enhancement phase-field models and computational strategies in order to make them applicable to more general, complex static and fatigue loading situations to predict crack initiation and growth in unified computational framework. Entire process of crack nucleation ...

Micro-RDC has developed portable radiation effects test structures that scale to new process nodes.These structures will enable the investigation of the effects of radiation on the new technology from the material processing level as well as the circuit level.Fabricating the chosen structures and the refinement of software to extract the model parameters will be completed in this effort.A suite of ...

The Internet of Things (IoT) connects people, data, and "things" (e.g., software, sensors, platforms), facilitating the translation of information into actions. Although naval platforms’ networks and communication suites have evolved significantly in the past few years to support such required connectivity, one of the greatest technical challenges still facing the military community is the proce ...
