The work proposed here augments the increasing body of research on capturing energy from walking. It focuses on the aspects associated with converting the captured energy, in the form of physical displacement, into an electrical form. The proposed Power Generator Back Pack is based on a Vernier Hybrid Machine (VHM) and magnetic gearing. The Vernier hybrid machine is a member of the family of vari ...

This STTR focuses on design of a hybrid propulsion system for a heavyweight torpedo. The hybrid torpedo propulsion system is designed to allow effective operation over a large turndown ratio, improving the weapon’s suitability for a broad range of missions including littoral water duty. The improved flexibility of hybrid torpedoes should improve the Pk and Pck (probability of kill, probability ...

The Marine Corps Expeditionary Fighting Vehicle utilizes 14 hydropneumatic suspension units (HSU) that have variable stiffness controlled by the nitrogen charge (mass) in each. Each HSU consists of a primary spring that contains a nominally 50/50 mixture of nitrogen and oil, and secondary spring that contains nitrogen with a small amount of oil. The vehicle ride height is effected by ambient tem ...

This Phase I STTR project will further develop our technique for uniformly dispersing single walled carbon nanotubes into polymeric resins. This project will specifically aim to provide them with a mechanism for anchoring themselves to an epoxy matrix during curing in such a way that they are able to accept and absorb an applied load. The successful development of this technology will result in n ...

The Navatek, Ltd. Team will successfully demonstrate the feasibility of using Fiber Reinforced Composites (FRC) materials to significantly reduce the weight of the (hull) structure of the Littoral Combat Ship (LCS) Unmanned Surface Vehicle (USV). We will use as a baseline for comparison our entrapment tunnel monohull (ETM) hullform. This hullform was selected by the Navy to satisfy the LCS (Flight ...

Surgical simulations aiming to support surgeon practices and medical education have attracted enormous research effort over the last two decades. However, the physical reality, especially on simulating aggregated tissue interaction, is still unsatisfactory. In this proposed work, an open source surgery simulation framework, SoFMIS, will be utilized and enhanced with tissue interaction models to a ...

To meet Navy needs for high performance and safe lithium ion (Li-ion) batteries for naval aircraft, ADA Technologies Inc. (ADA) and its university collaborator propose to develop and optimize tailor designed nanoporous separators derived from functionalized block copolymers (polyolefins) with low cost precursors. The innovative strategy provides a powerful tool to allow exquisite tuning of perform ...

Oceanit proposes to develop and demonstrate novel, tailored, designer separator materials with optimized properties to maximize lithium-ion cell/battery performance, life, safety and reliability.

The ISSAC Team leverages existing knowledge and expertise in power system monitoring, fault identification, localization and isolation in conjunction with rich, deep data analytics for pattern matching to devise a system for Medium Voltage Direct Current (MVDC) power system fault management. Because of the differences between AC and DC power grids there are a significant number of problems in deal ...

Future power systems on board Navy ships require electrical power in the order of 20 to 80 MW, which currently cant be provided by conventional copper or aluminum power cables. Advanced Conductor Technologies LLC (ACT) has been developing high-temperature superconducting Conductor on Round Core (CORC) power transmission cables, rated at 10 kA per phase, for the Navy that form a potential solution ...
