Image Gallery (2 images)
August 8, 2008 The ScanEagle is a low-cost, long-endurance autonomous unmanned aircraft that has been one of the most significant new battlefield technologies to emerge during the wars in Iraq and Afghanistan, performing more than 100,000 combat hours in both theatres and delivering invaluable intelligence, surveillance and reconnaissance (ISR) on a daily basis. The only trouble is that conventional electro-optical and long-wave infrared cameras are severely limited in fog or rain. Now they’ve managed to miniaturize a short-wave infrared (SWIR) camera to fit inside the diminutive ScanEagle, enabling clear vision in any circumstance.

Image Gallery (6 images)
May 29, 2008 Unmanned aerial vehicles represent one emerging technology that has delivered as promised over the last decade, achieving critical relevance in battlefields situations where they can perform both reconnaissance and combat roles without putting humans in the the line of fire. In addition to the rapid growth and development that has occurred in relation to larger, weapons capable craft, smaller systems have also proved their worth, and the latest announcement from AeroVironment (AV) is further evidence that this sector will continue to flourish. The company which has already established unmanned micro air vehicle (MAV) programs - including the Raven and Wasp III - has now received funding to continue development of an even smaller scale platform dubbed the Nano Air Vehicle (NAV).

Gizmag first reported on Boeing’s A160T Hummingbird Unmanned Rotorcraft back in 2005 and again in 2007 when the craft made its first flight. Now the craft has come very close to achieving the original 20 hour flight times envisioned (and unofficially broken a world record for unmanned aerial vehicles along the way) by remaining in the air for 18.7 hours.
Odysseus: Aurora's radical, unlimited endurance, solar powered aircraft
Image Gallery (3 images)
May 2, 2008 Aurora Flight Sciences has revealed the design of the aircraft it hopes will achieve the ambitious goals set out in DARPA's ambitious Vulture program: sustained uninterrupted flight for over five years at altitudes of 60,000-90,000 feet. Known as Odysseus, the solar-powered concept aircraft is as radical as the mission it is designed to accomplish, combining three self-sufficient “constituent aircraft” in a unique Z wing configuration that spans almost 500 feet (150 meters). The modular design provides several advantages - the shape of the aircraft can be adjusted to maximize the solar collection properties during the day and spread flat for aerodynamic efficiency at night-time, and because each of the constituent vehicles is capable of autonomously docking at altitude, the design also facilitates the replacement of one section of the plane whilst it is still aloft.

Unmanned Vehicle “Swarming”
Image Gallery (2 images)
September 1, 2007 The dynamics of the battlefield have changed many times over the centuries as new "killer" technologies have emerged, and another change is about to occur thanks to the evolving role of unmanned systems. As on-board sensor data processing technologies have improved dramatically, the vehicles can function as fully robotic systems, capable of making their own decisions. With these technologies, unmanned systems can act as part of a distributed, intelligent network on the battlefield, processing, sharing and communicating critical data. As a key component of joint, network-centric operations, intelligent vehicles can perform the data processing and communications normally handled by personnel in the field or at a centralized location.

Next-generation Sky Warrior's maiden flight a success
Image Gallery (2 images)
June 18, 2007 Resurrecting a great name from the 1950s, General Atomics have completed the maiden flight of their Sky Warrior Unmanned Aerial Vehicle (UAV). While the original, built by Douglas, was known for being the largest and heaviest "whale" of a bomber to take-off and land on aircraft carriers, the new Sky Warrior will operate as an unmanned long range surveillance, communications and weapons delivery drone. Able to run happily on diesel or jet fuel due to its Heavy Fuel Engine, the Sky Warrior will form a key part of the U.S. Army's Extended Range/Multi Purpose Unmanned Aircraft system.
Successful autonomous landing of a damaged UAV

May 31, 2007 One of the advantages of having a human at the controls of an aircraft when things go wrong is that we have the ability to adjust and intelligently work around a problem – the tales of valiant airmen bringing home planes that have no right to still be flying are myriad. Now it seems that the humble, computer-controlled UAV is set to learn such skills too. Flight control and navigation systems provider Athena Technologies recently demonstrated the damage tolerant flight control and autonomous landing capabilities on a subscale F/A-18 UAV.

Cyborg machine-insects prepare for the battlefields of the future
Image Gallery (11 images)
May 31, 2007 Cyborgs and bionic humans have long been the domain of science fiction with the concept popularised by the seventies TV series, Six Million Dollar Man, about a cyborg working for the OSI. As technological development funded by military spending has accelerated in recent times, we’ve seen the development of the bionic eye, the bionic hand and the bionic arm, with lots of work also being done in the area of exoskeletal robotics to help soldiers run faster and longer and carry heavy loads. Now it appears that we’re about to see the concept of Unmanned Aerial Vehicles (UAVs) and Cyborgs morph. Whilst UAVs have been among the most successful and high-profile innovations in military technology over the past decade, the arena of unmanned aerial technology is about to become a whole lot stranger as hybrid insect-machine "cyborgs" become a reality. The prospect of a remote controlled dragon-fly capable of transmitting video and other environmental data from the front-line still seems like the stuff of science-fiction, but research into hybrid insect-machines is accelerating under the auspices of DARPA.
Military fast jet pilot directs multiple UAVs
Image Gallery (3 images)
April 4, 2007 The networked battlespace of the not-too-distant future is beginning to look very much like a remake of Alfred Hitchcock’s classic box office thriller, “The Birds” with hordes of Unmanned Aerial Vehicles (UAVs) combining to overwhelming effect. QinetiQ and the UK Ministry of Defence (MOD) last week demonstrated a new system which provides a single pilot with the ability to fly their own military fast jet while simultaneously directing up to four further unmanned aircraft. The system gives unmanned aircraft an advanced level of autonomously - independent decision-making including self-organisation, communication, sensing the environment, identifying possible enemies, and targeting of weapons with the final decision to shoot retained by the human pilot. The technology developed for these trials is feeding the Taranis combat UAV and ASTRAEA projects, the latter exploring the use of UAVs for non-military applications. The ability to direct multiple UAVs could be useful for search and rescue, disaster relief operations and environmental monitoring, just for a start.
AeroVironment Aqua Puma UAV completes Royal Australian Navy Sea trials
Image Gallery (3 images)
February 9, 2007 AeroVironment's Aqua Puma small unmanned aircraft system (SUAS) has successfully completed sea trials for the Royal Australian Navy to explore adding a UAS capability to the Navy’s new Armidale class patrol boats. AV’s Aqua Puma is launched by hand, lands directly onto the sea surface and is recovered by hand from vessels. It is a next-generation FQM-151 Pointer, with the same form factor but increased endurance (1.5 hours) and enhanced sensor capability. Adding the Aqua Puma to the Armidales will require no ship modifications and will add significant day and night reconnaissance and surveillance capability.
England’s Taranis to be one of the largest UAVs ever
Image Gallery (6 images)
January 6, 2007 Yet another potent UAV is in the development phase, this one for the UK Ministry of Defence to be constructed by a team headed by BAE Systems, together with Rolls-Royce, Smiths Aerospace and QinetiQ, plus MoD military staff and scientists. The four year project to develop a world-class UAV (Unmanned Air Vehicle) Technology Demonstrator Programme called Taranis. Ground testing of the UKP124 million Taranis project is expected to take place in early 2009 with the first flight trials taking place in 2010. Named after the Celtic God of Thunder, Taranis will be an unmanned fast jet demonstrator the size of a Hawk trainer - making it one of the world's largest UAVs - that will be stealthy, fast and be able to test deploy a range of munitions over a number of targets and be able to defend itself against manned and other unmanned enemy aircraft.
Recoilless technology provides killer app for UAVs
Image Gallery (14 images)
December 12, 2006 The technological progress of the Unmanned Aerial Vehicle has been astonishingly rapid. At the beginning of the current Afghanistan and Iraq conflicts, it’s fair to say that UAVs were regarded as a reconnaissance tool for improving situational awareness but from the time the first Hellfire missiles were fired from an RQ-1A Predator UAV during 2002, the enormous advantage of an armed UAV that can help identify and eliminate a target has been recognised. Predators can prowl and strike where conventional military force cannot. In September we wrote about the first purpose-built hunter-killer UAV, and now the rush is on to add armaments to smaller UAVs. UAVs must be relatively large to withstand the recoil of the weapons they shoot, so weapon caliber has been limited. Now a new recoilless technology is set to revolutionize the small UAV’s role in the battlespace - Recoilless Technologies International (RTI) has signed a Joint Commercialization Agreement with UAV manufacturer, Tactical Aerospace Group (TAG). The new technology offers effective elimination and control of recoil and hence enables very small UAVs to pack a massive wallop. That’s just the start though because the technology can be applied to larger caliber weapons systems so everything that flies, floats or moves on land will also be able to pack a similar increase in firepower. Who knows how small a killer UAV can get? We have visions of a swarm of semi-autonomous, networked, killer microbots shooting miniature poison-tipped darts as in Dan Brown's novel, Deception Point.
RCV awarded engine contract for Micro Air Vehicle
Image Gallery (5 images)
December 8, 2006 There’s a delicious irony about the success of UK-based RCV Engines. The company achieved international recognition for its range of model aircraft engines then moved into a new market earlier this year with the development of its proprietary Rotating Cylinder Valve (RCV) engine for sub-250cc applications such as motorcycles, scooters and power tools where it offers 100PS/litre performance and manufacturing costs akin to those of a two-stroke, with the emission levels and fuel consumption of a four-stroke. The engine is so promising that it has been selected by Honeywell to produce a demonstrator engine based on RCV technology for use in Honeywell’s backpack-sized Micro Air Vehicle (MAV) – the irony is of course that the company is effectively back in the same domain it started from, though model aircraft enthusiasts who own one of RCV’s traditional SP or CD Series engines can rejoice in knowing that company is also powering some of the most innovative flying machines ever built. Another plus for the Rotating Cylinder Valve (RCV) engine is its exceptional power to weight ratio and it’s ability to run on a variety of fuels. The MAV autonomous surveillance aircraft has been developed as part of the US Defense Advanced Projects Agency (DARPA) MAV Advanced Concept Technology Demonstration programme and is small enough for a foot soldier to carry. It is designed to provide soldiers with improved situational awareness without exposing them to enemy fire through forward- and downward-looking video cameras that relay information to a remote ground station video terminal.
GoldenEye 80 ducted fan UAV makes successful first flight
Image Gallery (6 images)
December 7, 2006 Flying saucer sightings are certain to be on the increase from this point forth as a new type of aerial vehicle comes into existence. The Aurora Flight Sciences GoldenEye 80 unmanned air vehicle made a successful first flight last month, becoming the first ducted fan UAV to fly under the power of a heavy fuel engine. The fully autonomous GoldenEye 80 UAV is being developed under contract to the Defense Advanced Research Projects Agency (DARPA) through its Organic Air Vehicle (OAV-II) program. The GoldenEye 80 is designed to give company commanders the ability to spot, identify, designate, and destroy targets. With its powerful sensors and quiet operation, the aircraft can dash to a target area, hover motionless in the sky, and observe and designate a target – all without being heard by people on the ground. The unique design and embedded capabilities of the GoldenEye 80 enable the UAV to be used for a variety of military missions, from conducting surveillance beyond hills in rural areas to gathering intelligence while flying between buildings in urban warfare operations.
