All marine craft accumulate wastewater in their bilge. Although mostly water, this bilgewater contains multiple types of contaminants, including heavy metals, fuel oils, lubricants, and coolant fluids. Small craft, such as the Marine Corps’ new Expeditionary Fighting Vehicle, do not have the ability to separate these contaminants from the water and so, when operating in environmentally sensitive ...

Increased littoral deployment of submarines and other naval vessels has seen an increase in biological fouling and clogging of vessel cooling systems resulting in costly cleaning procedures and curtailed operations pending completion of cleaning procedures. To address and reduce the increased threat of biofouling, the Navy has begun installing electrolytic chlorination systems in submarines and s ...

The objective of the project outlined in this proposal is to determine the feasibility of a communications tool that could prioritize and optimize information exchange. Information exchange requires communication across multiple internal and external network systems utilizing a submarine’s limited external communications capability, multiple internal networked subsystems and multiple classifica ...

Alaska Native Technologies (ANT) and Johns Hopkins University-Applied Physics Lab (JHU-APL) have teamed to present an innovative, solution to the acoustic inversion sensor problem by combining a new, cost effective, high gain, broadband array (JHU, sponsored by ONR Code 32) with a new UUV (glider, ANT, sponsored by ONR Code 321) designed to operate in littoral areas that has extensive onboard proc ...

The proposed MFA is a complex, highly integrated architecture comprising a number of distinct radiating structures in a very compact package. The antenna design centers around a pair of conical radiators, which are DC (Direct Current) connected to the chassis/fuselage of the aircraft, as required in MIL-E-5400. These conical radiators are shared for simultaneous operation on 30-88 MHz, 118-174 MHz ...

A software system for predicting the performance of antennas mounted on electrically large platforms of arbitrary geometry and with material coatings is proposed. The system will be based on the utilization of high frequency methods for modeling antenna-platform and antenna-to-antenna interactions and the influence of the platform geometry and materials. The system will run on personal computers a ...

The U.S. Navy has significant interest in the development of composite materials which substantially improve the performance of composite propulsor blades. Improvements in erosion resistance (e.g., cavitation, rain, and sand) and impact durability are of particular interest. These improvements must be enabled without degrading other performance characteristics including vibration damping and mec ...

The U.S. Navy has significant interest in the development of advanced, lightweight structural concepts for the next generation of Air Cushion Vehicles (ACV) that enable enhanced operation performance. In particular, these structural concepts must provide reduced weight and life-cycle costs with increased structural performance. To meet these future performance goals, advanced structural material ...

This proposal provides for the development of low-cost Li(Si)/FeS2 thermal batteries through the use of novel and unconventional methods for electrode fabrication that should drastically reduce the cost of thermal batteries and dramatically improve performance. Preliminary tests have been carried out to show the feasibility of the preparation of the cathode electrode by painting. The capacity of t ...

A conceptual Fischer-Tropsch (FT) based process is proposed for converting synthesis gas to C9 C16 hydrocarbons suitable for Navy use as synthetic JP5 fuel. We shall develop an advanced FT catalyst selective for C5-C8 olefins that will be subsequently dimerized to C10-C16; optionally, the process will include product upgrading, e.g., partial reduction. Phase I will investigate in parallel two cr ...
