Sound Attenuation of Neoprene Wetsuit Hoods as a Function of Dive Depth and Acoustic Frequency: Hyperbaric Chamber Trials

The U.S. Navy is interested in strategies that divers could employ to protect them from loud underwater sounds. Sonar transmissions and other forms of underwater sound, such as that produced by noisy underwater tools, are an occupational hazard for U.S. Navy divers.

The CAN Bus: Driving the Future of Autonomous Military Vehicles

It’s a crisp November day in Michigan, and a convoy of British and American resupply vehicles are rumbling along at a comfortable 25 miles per hour. In the lead is a British Army Rheinmetall MAN Military Vehicles (RMMV) HX-60 truck, trailed closely by two U.S. Army Oshkosh Light Medium Tactical Vehicles (LMTVs). In total, there are zero humans operating this convoy.

Autonomous “Wingman” Vehicles

The US Army’s Futures Command is the most important administrative reorganization of the modern Army. Responding to the world’s changing priorities— especially the “near peer” threat of ascendant Russia and China—the Army is no longer modernizing, but re-inventing its ground vehicle fleet against new realities. Just like the U.S. Air Force stopped inventing better jets and pilot aids and moved to unmanned aerial vehicles (UAV) for “dull, dirty and dangerous” missions, the Army envisions multiple autonomous vehicle concepts. Instead of a heavier Abrams main battle tank, or a replacement to the aging M113 APC, autonomous “wingman” vehicles may replace some of the human-heavy tasks on the future battlefield.

AUVSI XPONENTIAL 2019: A Close-Up Look at Air Taxis

AUVSI’s XPONENTIAL unmanned vehicles and robotics show opened today in Chicago’s cavernous McCormick Place and the most impressive exhibit on the show floor had to be Bell Helicopter Textron’s Bell Nexus air taxi.

Bell is partnering with a Who’s Who of high-tech companies such as Electric Power Systems, Garmin, Moog, Safran, and Thales on the project that could someday alter the future of transportation. A steady stream of interested attendees took advantage of the opportunity to get a close-up look at the vehicle.
