University Opens New Ballistics and Impact Dynamics Lab

Wichita State University’s National Institute for Aviation Research recently opened a new ballistics and impact dynamics research lab in the former Britt Brown Arena at the Kansas Coliseum. The new ballistics lab, part of NIAR’s environmental Test Labs, uses a custom built ballistic firing device to propel 22-50 caliber rounds into components inside a concrete containment building. The test is designed to simulate the impact of a structural failure on the aircraft.

Army Researchers Enable Night Lethality

In science fiction, technology problems are solved with the stroke of a writer's pen. In reality, science and technology research takes time, and a lot of effort.

New DARPA Technologies Could Make Cyber Warfare a Reality

Three years after the Defense Department named cyberspace a new domain of warfare, the Defense Advanced Research Projects Agency is unveiling technologies that could soon make it possible for military leaders and warriors to plan and execute real-time cyber missions in a territory charted so far only by machines.

Unmanned "Urban Beat Cop" Surveillance System Protects Soldiers

In a non-combat environment, information is typically collected by local law enforcement officers who are "walking their beat." Air Force expeditionary forces in Afghanistan requested a system that would give them similar situational awareness in Afghan villages and other remote areas, but without human participation or requiring them to "walk a beat." So, the Air Force and a small business partner recently developed and tested in the field a small, unmanned aircraft system (SUAS) that allows U.S. military forces to perform strategic reconnaissance while staying out of harm's way.

Researchers Create Energy-Absorbing Material

Materials like solid gels and porous foams are used for padding and cushioning, but each has its own advantages and limitations.A team of engineers and scientists at Lawrence Livermore National Laboratory (LLNL) has found a way to design and fabricate, at the microscale, new cushioning materials with a broad range of programmable properties and behaviors that exceed the limitations of the material's composition, through additive manufacturing, also known as 3D printing. Livermore researchers, led by engineer Eric Duoss and scientist Tom Wilson, focused on creating a micro-architected cushion using a silicone-based ink that cures to form a rubber-like material after printing. During the printing process, the ink is deposited as a series of horizontally aligned filaments (which can be fine as a human hair) in a single layer. The second layer of filaments is then placed in the vertical direction. This process repeats itself until the desired height and pore structure is reached.The researchers envision using their novel energy-absorbing materials in many applications, including shoe and helmet inserts, protective materials for sensitive instrumentation, and in aerospace applications to combat the effects of temperature fluctuations and vibration.SourceAlso: Read more Materials tech briefs.

DARPA Teams With Industry to Create Spaceplane

DARPA has created an Experimental Spaceplane (XS-1) to create a new paradigm for more routine, responsive, and affordable space operations. In an important step toward that goal, DARPA has awarded prime contracts for Phase 1 of XS-1 to three companies: The Boeing Company (working with Blue Origin, LLC), Masten Space Systems (working with XCOR Aerospace), and Northrop Grumman Corporation (working with Virgin Galactic).
