A Mighty Wind: Using Wind Tunnels to Measure Sound by Deadening the Noise
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.
Mine Mission: Marine Corps Looks to Boost Mine Countermeasure Capabilities
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.
Electric Boat Competition Sparks Interest in Naval Science Careers
Student engineering teams from Princeton, Washington College and the University of Alabama have won first place in their respective events at the “Promoting Electric Propulsion” (PEP) boat races, sponsored by the Office of Naval Research (ONR) and the American Society of Naval Engineers (ASNE). In just six years, this electric boat-building competition has grown from a single university to 34, with more than 200 students who took part in the five-mile races on Broad Bay in Virginia Beach. Dr. Steve Russell, program officer, Sea Warfare and Weapons department, said he launched the PEP competition with a colleague from ASNE, Dr. Leigh McCue, and Tim Cullis, Naval Sea Warfare Center Carderock, after seeing a public race by local hobbyists in the Chesapeake Bay.
Awesome Algorithms: Prize Challenge Tests Software Performance in Unmanned Vehicles
The Office of Naval Research (ONR), Naval Surface Warfare Center Crane Division (NSWC Crane) and the NavalX Midwest Tech Bridge recently sponsored a three-stage competition called the Artificial Intelligence for Small Unit Maneuvers (AISUM) Prize Challenge.

Tech FLEX: ONR SCOUT Experimentation Event Showcases Value of Unmanned
ONR SCOUT is an ongoing, multiagency experimentation campaign to identify new ways to bring unmanned technologies to warfighter problems, test them in realistic operating conditions and get them to the fleet and force. SCOUT is committed to partnering with industry to get nontraditional, commercial-off-the-shelf, government-developed and/or government-sponsored technologies to the fleet rapidly.
