People often need to be rescued at sea because of stormy weather – exactly the kind of conditions in which it is not safe to fly. Nonetheless, fully-crewed helicopters and fixed-wing aircraft are regularly sent out into such weather to perform maritime rescues, endangering both the crew and the expensive aircraft themselves. Soon, however, a new type of unmanned remote-control aircraft may be able to do the job. Not only would flight crews be kept out of harm’s way, but as demonstrated by a functioning prototype, the aircraft would outperform conventional planes in rough weather, thanks to shape-shifting technology.

QinetiQ has filed for three world records for Zephyr, its solar powered high-altitude long endurance (HALE) Unmanned Air System (UAS), with the Federation Aeronautique Internationale (FAI) – the world governing body for air sports, aeronautics and astronautics world records. The three records subject to ratification are the absolute duration record for an Unmanned Air Vehicle, the duration record for a UAV in the U/1.c / 50-500Kg category and the absolute altitude record for a UAV in that category of 70,740ft (21,561m).

After AeroVironment’s recent announcement that its Global Observer unmanned aircraft system (UAS) had successfully completed a series of Wing Load tests the team apparently wasted no time getting the craft in the air for its maiden flight. On August 5 Global Observer 1001 took off from Edwards Air Force Base (EAFB) in California and climbed to an altitude of 4,000 feet where it performed a series of maneuvers before landing successfully one hour later.

AeroVironment has passed a critical milestone in the development of its Global Observer unmanned aircraft system (UAS). The company reports that the High Altitude Long Endurance (HALE) aircraft has completed a series of Wing Load Tests at NASA's Dryden Flight Research Center – proving that the aircraft's all-composite 175-foot wing can withstand the level of dynamic stress it will be subjected to at altitudes of between 55,000 and 65,000 feet.

Day after day, honeybees are able to travel back and forth between a food source and their hive, even in a constantly-changing environment. Given that the insects have relatively small brains, scientists have determined that they rely chiefly on vision and hard-wired visual processing abilities to achieve such a feat. To better understand that process, scientists from the Cognitive Interaction Technology Center of Excellence at Bielefeld University, Germany, have created an artificial honeybee’s eye. Using the device, they hope to unlock the secrets of the insects’ sensing, processing and navigational skills, and apply them to human technology such as micro air vehicles (MAVs). Read More

Global Hawk, Northrop Grumman’s sophisticated unmanned high altitude surveillance aircraft is finding its niche in unexpected areas. In April, 2010, in consort with NASA, a Global Hawk fitted with scientific instruments completed 82.5 flight hours cruising at latitudes ranging from the Arctic Circle to just near the equator as part of an ongoing civilian research program known as GloPac, or Global Hawk Pacific Program, which aims to study atmospheric conditions over the Pacific and Arctic oceans.

Unveiled earlier this week in St. Louis, Boeing's Phantom Eye will set a new benchmark in long-endurance unmanned aerial vehicle (UAV) technology when it takes to the skies in 2011. With a wing-span of 150-feet, the hydrogen-powered aircraft will cruise at 150 knots, carry up to 450-pounds and stay aloft at 65,000 feet for up to four days. Boeing calls it a game-changer, and plans are already in progress to build a bigger version that can remain airborne for 10 days. Read More

A prototype of England’s Taranis Unmanned Combat Aircraft System (UCAS) that we first covered back in 2006 has been unveiled for the first time by the UK Ministry of Defence (MoD). Three and a half years in the making and the product of more than a million man-hours the concept demonstrator is designed to test the possibility of developing the first ever autonomous stealthy UCAV that would ultimately be capable of precisely striking targets at long range, even on another continent.

A young robotics engineer has developed a perching mechanism that could be invaluable to the field of Micro Air Vehicles, or MAVs. Mirko Kovac, of Switzerland’s Ecole Polytechnique Federale de Lausanne (EPFL), envisions a system wherein swarms of tiny robotic gliders would be deployed over scenes of disasters, such as forest fires or earthquakes. The gliders would fly straight into the sides of vantage points, such as tall buildings or trees, whereupon they would perch on that surface and transmit data to remote observers via cameras or other sensors. They could even free themselves, to fly on to another location. Read More
