UAV

While UAV’s continue to reshape the theater of war, they are also finding more and more non-military applications, from gathering atmospheric data to delivering supplies to remote villages. Now Aerovironment is examining the potential for its UAVs to rapidly re-establish communications when existing communications networks are knocked out following a natural or man-made disaster.

Hovering unmanned aerial vehicles (UAVs) – most of which take the form of quadrocopters – are currently being developed for a wide range of applications. Some of these include the delivery of supplies to remote locations, urban reconnaissance, and military operations. Whether they’re flying solo or in organized swarms, however, they constantly need to be aware of potential collision hazards, both mobile and stationary. While various technologies are already being utilized for this purpose, Germany’s Fraunhofer Institute for Microelectronic Circuits and Systems has developed a new 3D CMOS sensor, that promises particularly good performance.

Lockheed Martin's new Shadow Hawk weapon is deceptively small considering the influence it will likely have on warfare from this point forward. The era of unmanned warfare is about to go to a whole new level. The Shadow Hawk is an 11-pound class, 2.75-inch (7 cm) diameter, 27-inch (68 cm) long drop-glide munition released a mile or more above the target by the equally diminutive unmanned RQ-7B. It may not seem like a major leap forward in weapons technology but it most certainly is, because the Shadow Hawk munition now arms an entire fleet of RQ-7s for the US Marines and Army that could previously only be used for reconnaissance, and it does so with a much smaller and cheaper weapon.

Although winged micro air vehicles (MAVs) are pretty impressive in free flight, one of the skills that has proven difficult for them to master is the bird-like perched landing. Aerospace engineers from the University of Illinois at Urbana-Champaign, however, have now achieved it – they’ve developed an MAV that is capable of landing on an outstretched human hand. Read More

In an attempt to combine the vertical take-off and landing (VTOL) capabilities of a helicopter, with the speed, range and altitude capabilities of a fixed wing aircraft, tiltrotor aircraft, such as the AgustaWestland AW609 and the Bell Boeing V-22 Osprey rely on powered rotors mounted on rotating shafts or nacelles at the end of a fixed wing. But the tiltrotor design isn’t the only option for aircraft looking to get the best of both worlds. Like Aerovironment’s SkyTote, the Flexrotor is designed to transition from vertical to horizontal flight without any pivoting of its rotor. Read More

Piracy on the high seas of the 21st century requires 21st century solutions. As part of the on-going effort to curb attacks on shipping, the United States Navy will use a UAV helicopter to test a new sensor system in the waters off California during the summer of 2012. This new 3D sensor package in combination with new computer algorithms will allow the Navy to more accurately identify pirate vessels hiding among innocent shipping on the sea lanes with much greater speed and much less manpower.

Take one piece of software that can stitch 2D photos into a 3D model, one camera-carrying UAV (unmanned aerial vehicle), and mix well to impress and inspire. This was the recipe used by Autodesk's Director of Strategic Research, Gonzalo Martinez, when he set about modifying an Octo-Copter UAV for use with Autodesk's 123D Catch software to simplify the process of making 3D models of large real-world objects, while also having some fun.

Nuclear-powered unmanned aerial vehicles (UAVs) that would increase operational flight durations from days to months are a technological possibility today, according to a feasibility study undertaken last year by Sandia National Laboratories and Northrop Grumman Systems Corporation. A nuclear power supply would additionally double the availability of electrical power to onboard systems, including weaponry, the study found. Read More

NASA has announced it will use a modular, unmanned flight research vehicle being built by Lockheed Martin for the Air Force Research Laboratory (AFRL) to test enabling technologies for new kinds of lightweight, energy-efficient, flexible aircraft. The small aircraft, dubbed the X-56A, will be used to explore ways to suppress vibrations and alleviate the load on flexible aircraft from wind gusts and atmospheric turbulence. Read More
