Antenna Design Turns Entire Vehicles into Broadcasting Equipment

High-frequency antennas transmit radio waves across vast distances and even over mountain ranges using very little energy, making them ideal for military communications. These devices, however, need to be huge to operate efficiently. Instead of adding more bulk, however, University of Wisconsin–Madison engineers are working to increase the effective size of antennas by turning the military vehicles that carry them into transmitters,using the structures that support the antennas themselves to help broadcast signals.

Army Scientists Synthesize High-Performing Energetic Material

Scientists at the U.S. Army Research Laboratory recently synthesized a new material called bis-isoxazole tetranitrate, or BITN, with potential applications in propulsion and lethality.

High-Tech Bird Watching Could Lead to Shapeshifting Airplane Wings

An international team of engineers and biologists will gain unprecedented insights into how birds fly so efficiently and then use that knowledge to build unmanned aircraft with shapeshifting wings. These planes should be lighter, faster and dramatically more maneuverable than today’s stiff-winged aircraft.

UAV Can Launch Aerial Missions from Underwater

Researchers at the Johns Hopkins University Applied Physics Laboratory in Laurel, Maryland, have developed an innovative unmanned aerial vehicle (UAV) that can stay on station beneath the water until needed, then launch into the air to perform a variety of missions. The Corrosion Resistant Aerial Covert Unmanned Nautical System — or CRACUNS — is a submersible UAV that can be launched from a fixed position underwater, or from an unmanned underwater vehicle (UUV). A team from APL’s Force Projection Sector worked with fabrication experts in the Research and Exploratory Development Department to create a new type of unmanned vehicle that can operate effectively in two very different arenas: air and water.

Detecting Radioactive Material from a Remote Distance

In 2004 British national Dhiren Barot was arrested for conspiring to commit a public nuisance by the use of radioactive materials, among other charges. Authorities claimed that Barot had researched the production of “dirty bombs,” and planned to detonate them in New York City, Washington DC, and other cities.

Tiny UAS Could Be Warfighters’ Eyes in the Sky

The basic small-unit fighting capability of the Army is the squad. One of its weaknesses is broad-area situational awareness, particularly in unfamiliar environments, according to Col. Phil Cheatham, deputy branch chief of the Electronics and Special Developments Branch at the Maneuver Center of Excellence (MCOE), Fort Benning, Georgia. A likely solution? A nano unmanned aerial system (UAS) with reconnaissance capability called the Soldier Borne Sensor (SBS).

Armed Forces Are Developing Laser Weapons

Responding to lawmakers' questions about how close the Army is to developing offensive and defensive directed-energy weapons, Mary J. Miller responded: "I believe we're very close." Miller, deputy assistant secretary of the Army for Research and Technology, testified before the House Armed Services Committee's Subcommittee on Emerging Threats and Capabilities recently regarding the Army's Science and Technology (S&T) Program for fiscal year 2017.

Electric Patch Holds Promise for Treating PTSD

An average of 30 years had passed since the traumatic events that had left them depressed, anxious, irritable, hypervigilant, unable to sleep well and prone to nightmares. But for 12 people who were involved in a UCLA-led study — survivors of rape, car accidents, domestic abuse and other traumas — an unobtrusive patch on the forehead provided considerable relief from post-traumatic stress disorder.

Researchers Design Bat-Inspired Wings for Micro Air Vehicles

Researchers from the University of Southampton have designed innovative membrane wings inspired by bats, paving the way for a new breed of unmanned Micro Air Vehicles (MAVs) that have improved aerodynamic properties, can fly over long distances and are more economical to run.

Robotic Falcon Captures and Retrieves Renegade Drones

Michigan Technological University is developing a drone catcher that could pursue and capture rogue drones that might threaten military installations, air traffic, sporting events — even the White House. It’s a deceptively simple system: a launcher that shoots a big net attached to a large drone by a string. The system can be autonomous, controlled by a ground-based human pilot, or a combination of the two.
