Northrop Grumman has announced that it will collaborate with Canadian aerospace and defence company L-3 MAS to send a variant of the Global Hawk Unmanned Aircraft System (UAS) into Arctic skies.  Read More

After four years of development, Boeing’s liquid hydrogen-powered Phantom Eye unmanned autonomous aircraft made its first flight last Friday. It took place at Edwards Air Force Base in California, with the dual-propeller-driven aircraft lifting off of its launch cart at 6:22am PST.  Read More

Eighty five years ago, Charles Lindbergh became the first pilot to successfully fly from New York to Paris non-stop, claiming a substantial cash prize and securing a place in history in the process. Now another world record holder, Chip Yates, has announced plans to take on the same aviation challenge ... but this time the aircraft making the 3,600 mile non-stop flight will be all-electric. The ambitious project is still in its early stages but the Flight of the Century team has already developed a patent-pending battery deployment solution to replenish depleted batteries while the aircraft is in flight.  Read More

The human implications for living in a world with UAVs are very much dependent on one's latitude and longitude at any given time. Though the term is likely to conjure images of covert military operations, it's not a connotation that the term, or the technology, necessarily implies. Fundamentally, a UAV is merely an unpiloted flying machine, and that's a potentially useful thing to have for all sorts of civilian applications. It's already happening. Exhibit A: research at the University of Granada into using small UAVs, equipped with cameras, that scan buildings in order to construct 3D models.  Read More

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.  Read More

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.  Read More

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.  Read More

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
