Zephyr solar-powered UAV breaks three more world records
The Zephyr is a winning machine. Last we reported, QinetiQ's solar-powered drone had just completed 7-days in the air, and counting. Now, the Federation Aeronautique Internationale (FAI) has confirmed that Zephyr completed that record-breaking flight with a solid 2-weeks in the air (336 hours). If that wasn't enough to put other drones to shame, FAI found that Zephyr also destroyed records for flight duration for a UAV of its class, and the altitude record for that class at 21,562 meters, or 70,741 feet. So keep the records coming, Zephyr, because everyone loves a winner, even when that winner is a unmanned war machine.
Lockheed Martin and Kaman's unmanned helicopter wins military contract (video)
When developing an unmanned vehicle there are two paths to choose from: create an entirely fresh design with no room for a carbon-based pilot, or simply take an existing craft and make it self-sufficient. That's the direction Lockheed Martin chose for its submission to the the joint Army Marines Autonomous Technologies for Unmanned Air Systems (ATUAS) program, and it turned out to be a winner. The idea is to create an autonomous helo that can resupply military forces, and Lockheed Martin started with a Kaman K-Max cargo chopper (demo'd after the break), capable of lifting 6,000lbs plus one pilot -- who was made optional. This customized K-Max can place its cargo within a 10 meter drop zone after flying 200km or more, but a principal advantage of this submission is that you can still put a pilot in there and use it like a traditional heavy lifter, while the competition from Boeing was a bespoke UAV with no room for meatbags. It's unclear when exactly this sentient K-Max will be hitting battlefields, but hopefully the Army and Marines come up with some other, rewarding jobs for their pilots, because between this and the Unmanned Aircraft Systems Roadmap released earlier this year that particular job market could be getting tight. Update: Bo from Lockheed Martin wrote in to let us know of a different video we've added after the break featuring higher production values, more guitar solos, and plenty of autonomous cargo liftin'.
Robotic yellow submarine finds massive river under the sea, tons of other trippy stuff
Researchers at the University of Leeds have employed a robotic yellow submarine to fund and begin documenting a massive river under the sea, known as a submarine channel -- the first ever directly observed. The river is so large that if it were on land, it would be the sixth largest river in the world. The torpedo-shaped autosub itself is a 23-foot long, unmanned craft which can be programmed to stay just safely above the channels where they'd encounter damage. It's equipped with an underwater speed camera which enable the team to observe in detail the flows within the channel. While little is known about what kind of lifeforms may lurk in these waters, the team's research puts science a little closer to understanding these unique rivers, and its full report will be published later this year in Geology.

Zephyr solar powered UAV lands after a fortnight in the air (whatever that means)
With all the excitement surrounding the solar powered UAV's record-breaking flights, we would be remiss if we didn't mention that QinetiQ's Zephyr has finally landed in an airfield in Arizona, 14 days and 24 minutes after take-off. This quadruples the previous unofficial world record for unmanned flight (which it set itself in 2008). This is a dramatic proof-of-concept, having flown longer without refueling than any other airplane. We'd like to imagine that this technology would be used primarily for delivering toys to children in developing nations, but something tells us that will have to wait until the military gets its hands on it. PR after the break.
Zephyr solar UAV sets yet another flight record: 7 days and counting!
This certainly is an interesting time for solar powered flight. Solar Impulse just returned from a 26-hour manned test flight, and now QinetiQ's Zephyr, a drone who we last saw clocking over 83 hours in-flight is in the air again: this time, it's more like seven days and counting! The craft, which took off from the Army's Yuma Proving Ground in Arizona last Friday, is being billed as an "eternal aircraft," one that can stay aloft for extremely long periods of time for use as recon and communications platforms. The previous world endurance record for a UAV was set by NASA's Global Hawk, which stayed aloft for 30 hours and 24 minutes.
IKAROS gets first burst of solar propulsion, wants more
Photons, man, it's all about the photons. Japan's solar sail-equipped IKAROS probe has recorded its first propulsion derived from the force of sunlight rays hitting its tender surface. The force generated is a truly minuscule 1.12 millinewtons, but that can go a long way (literally) in a frictionless environment like space. The kite's sails also soak up Sol's emitted light to generate electricity, making the most out of the one resource available to it. So now that we've figured out how to do all that, shall we get started on colonizing Mars or what?
Boeing's unmanned Phantom Ray makes dramatic video debut, set to take off this December
The big new trend among wargadget makers seems to be the elimination of the fleshy operator, and we're seeing it happening with helicopters, boats, and even space shuttles. The Phantom Ray is Boeing's take on how we can do the same to jet fighters, and it's had its official unveiling in St. Louis this week. Primarily intended to serve as a reconnaissance and intelligence drone, this 36 foot-long airborne robot will be able to cruise at speeds of up to 614mph, and will even do a bit of suppression fire when you need it to. It's designed to be undetectable by radar and offers a minimal heat signature for missiles to lock on to, as its engine is buried deep within the body. Sounds ominous indeed, but the Phantom Ray will serve as the testbed for even more advanced technologies and will take its first flight in December of this year. See its grand debut on video after the break.
Tiny, robotic space shuttle to be launched into orbit in April
A long-delayed project initiated by NASA and carried out by Boeing may finally get to see the light of cold, beautiful day according to reports from the US Air Force. The X-37, a small, robotic space plane is set to make its first unmanned trip into orbit in April. Conceived by NASA as an unmanned re-entry lifeboat for crew of the International Space Station, the X-37 reportedly has a cargo bay of just 7 x 4 feet, and it has apparently been shipped to Florida for its maiden voyage, where it will be mounted to an Atlas V rocket for its launch into space. There aren't any other details -- the people running the project are keeping everything pretty quiet, but the shuttle itself is reported to have said that it's putting itself "to the fullest possible use," adding that that "is all I think that any conscious entity can ever hope to do."
Harbor Wing AUSV can sail into the sunset all by itself
Autonomous seafaring vehicles may not be quite as common as unmanned land or air vehicles, but Harbor Wing Technologies looks to be doing its small part to change that, with it now apparently pretty far along in the development of its self-named Autonomous Unmanned Surface Vehicle (or AUSV). Among other things, it employs a specially-designed "WingSail" that can rotate a full 360 degrees to let the vessel maneuver efficiently upwind or downwind, and it uses a custom-made guidance system that can relay vital navigational and situational data to a "semi-portable" command station, which can apparently also be used to pilot the vessel in a pinch. Be sure to head on past the break for an interview with Harbor Wing's Ken Childress courtesy of Engineering TV, which also includes a glimpse of the current prototype in action.[Via Engineering TV]
Kansas researchers readying unmanned polar plane
It's been a long time coming, but the Meridian aircraft that Kansas researchers set out to build late last year is nearly complete. Reportedly, the unmanned polar plane is part of "a larger effort at the University of Kansas's Center for the Remote Sensing of Ice Sheets," and it will head to locales such as Greenland and areas of the Antarctic in order to "provide a detailed picture of ice layers and, in particular, the boundary between ice and ground." To withstand the chilly temperatures it's bound to face, designers have even equipped the wings with de-icing capabilities and heaters to keep the internal electronics from freezing up. If all goes as planned, Meridian will head out on its "maiden flight next summer," with another trip slated for later in 2008.
Solar-powered plane breaks unmanned flight record
According to a BBC report today, a UK defense firm called Qinetiq has developed and tested a lightweight, solar-powered plane which has just broken the world record for longest unmanned flight. The plane, known as the Zephyr, spent 54 hours in flight using only self-recharging solar power, thus breaking the 30-plus-hour flight of the previous record holder, the US Air Force's Global Hawk surveillance craft. Although the record has been smashed, the plane won't be eligible for entrance into the "official" record books due to a late announcement of the feat, though another 33-hour flight might make the cut. The plane -- which has a wingspan of 59-feet -- is controlled from the ground after a hand liftoff, and is capable of cruising at 58,000 feet. According to the designers, the Zephyr is, "Going to go a lot higher and a lot further," and added that, "You ain't seen nothing yet." Indeed, ICEMAN, indeed.
US Air Force takes delivery of micro unmanned aircrafts
Shortly after the Navy announced its intentions to utilize unmanned combat aircrafts, the US Air Force is making sure it doesn't get left behind by taking delivery of "its initial BATMAV micro unmanned aircraft systems (UAS)." Among the diminutive crafts is a legion of Wasp IIIs, which have a wingspan of 29-inches, weigh in at just one-pound apiece, and carry integrated forward and side looking electro-optical color / infrared cameras. The backpackable devices are meant to be hand-launched and aim to provide "real-time video imagery to a handheld controller used by tactical units" in reconnaissance, surveillance, and target acquisition missions. Now, if only these things had an ultra-lightweight chaingun strapped under each wing and were available at the local BX, we'd be sold.[Via The Raw Feed]
Navy gears up for unmanned combat aircraft
While the idea of an autonomous flying military bot is far from new, the US Navy has taken a first step toward "developing an unmanned combat aircraft that some advocates say could compete with Lockheed Martin's F-35 joint strike fighter." Northrop Grumman was awarded a $636 million contract to design, build, and fly an Unmanned Combat Air System "that would operate from the decks of the Navy's giant nuclear-powered aircraft carriers," and if things goes as planned, we could see the gunners join our forces "within 10 to 15 years." And considering that we're already deploying land-based mechanical soldiers to fire our weapons, we'd say the full-fledged robotic army is certainly closing in.[Image courtesy of DefenseTech, thanks Jason]
SeaAway's offshore Sea Sentinels detect incoming contraband
A Florida-based startup dubbed SeaAway (no relation to Segway, truth be told) is looking to make our ports a good bit safer in the future by implementing an offshore screening process that could detect "chemical, biological, and nuclear traces as ships travel through." The aptly-dubbed Sea Sentinels would be anchored to the seafloor some 14-miles from a port, and will even house up to 15 humans and an array of unmanned aerial vehicles for extreme situations. The platforms would utilize RFID readers to detect what types of cargo passed through its screen, and if sensors flag a suspicious container, the Coast Guard is called into action. Unfortunately, the $100 million it costs to erect each system would have to be subsidized by a passage fee of $20 per container, but tax breaks for shippers are currently be pondered. Nevertheless, a prototype system will see construction later this summer, and if all goes well, finalized versions could be patrolling our seas in the not too distant future.
Boeing's unmanned A160T Hummingbird helicopter takes flight
It's been a few ticks since we've seen Boeing send an atypical aircraft into the friendly skies, but the firm's latest helicopter has successfully completed a 12-minute test flight without so much as a pilot on board. The A160T Hummingbird unmanned rotorcraft is a turbine-powered "warfighter" that aims to provide "intelligence, surveillance, and reconnaissance coverage" in locales that could make even the most calloused veteran queasy. During its time in the air, it reportedly met every objective set for it, and while we've no idea how soon this thing will be lifting itself up, it'll eventually reach speeds of up to 140 knots and stay airborne for up to 20 hours before returning to base for a pat on the wing.[Via The Raw Feed, image courtesy of SkyControl]
