The Ocean Battlespace Sensing Department explores science and technology in the ocean battlespace environment.

ONR Global TechSolutions program is sponsoring efforts to convert aluminum into hydrogen fuel, which could potentially serve as a portable, readily available power source.

As conflicts become compressed in time and more complex, with an increasing number of data sources and platforms feeding information to warfighters, it is a challenge to build and share a complete and accurate operational picture.

The Office of Naval Research (ONR) sponsored a project at Virginia Tech University nearly 20 years ago that is now growing in influence across the world for measuring aerospace and aeronautical acoustics. Since noise reverberates against solid surfaces, such as the walls of a wind tunnel where acoustical testing takes place, collecting accurate sound data had been nearly impossible at the time. Researchers were also struggling to discern the sound of the wind tunnel’s air flow from the noise of the object traveling through it. After learning about some experiments on Kevlar as a wind screen, William Devenport, an engineering professor and director of Virginia Tech’s Stability Wind Tunnel, said he and a colleague wrote a proposal to then-ONR program officer Ron Joslin to try adding Kevlar to their wind tunnel walls. Devenport submitted the original grant proposal (N00014–04–1–04933) through the FY 2004 Defense University Research Instrumentation Program (DURIP) for alterations to Virginia Tech’s existing Stability Wind Tunnel that would allow it to measure flow-induced noise of relevance to Navy applications.

At the Technical Concept Experiment 23.2, held at Marine Corps Base Camp Pendleton, California, ONR showcased multiple systems designed to enhance the Marine Corps’ capability in carrying out amphibious operations — including explosive hazard defeat/mine countermeasures as well as intelligence, surveillance and reconnaissance.

The proposed topic will explore and exploit the lack of underwater propulsion systems that can efficiently work across a wide variety of speeds over long distances. In particular, this effort is interested in a propulsion system able to transition between low and high speeds, to include the ability to stop and re-start at any time. Other desired characteristics will be briefed at the event. The program will pursue technologies and systems that support development and demonstration of a system that can propel an underwater vehicle in the ways listed. Further mission profile details will be provided at the Industry Day.
