Unmanned

We've seen the value of using multiple rotors in unmanned microcopters like the CyberQuad, DraganFlyer X8 and more recently Parrot's AR.Drone. The HexaKopter is another case in point - the 1.2kg, six-rotor device has a flight-time of up to 36 minutes and can carry around 1kg along with a high-definition camera that delivers some amazing images. And it's also a lot of fun.  Read More

Metal Storm has been granted another round of patents and one in particular has important implications for the future of minefields. The company’s weapon technology functions somewhat like an inkjet printer, using computer-controlled electronic ignition and a system of stacked projectiles in multiple barrels. As each barrel can contain a variety of projectiles, it can fire a sensor from each of the barrels to cover an area with sensors. If any sensor is triggered, the barrel to which it belongs fires a subsequent explosive projectile to the exact same point. The system offers many advantages, including the ability to be switched off leaving no explosive ordnance remaining in the area that had been protected. With landmines being one of the most dreadful and enduring legacies of war, it’s an enormous shame that only one side will be using Metal Storm, as it represents a potential solution to the deployment of this insidious device.  Read More

The age of unmanned aerial vehicles UAVs has well and truly dawned but designers aren't resting on their laurels when it comes to improving the capabilities of these multi-talented aircraft. One innovation that's come to the fore recently is the use of an enclosed four rotor platform (see our recent look at the CyberQuad) which offers a number of advantages including greater stability, agility, hovering ability and a smaller footprint. This unique new design from Britain's VTOL Technologies takes this idea a step further, adding four movable rotors to a single "flying-wing" to create an aircraft that claims to deliver a higher payload capacity for its size and up to four times the endurance of current vertical take-off and landing (VTOL) UAV designs.  Read More

The first of the next generation of Northrop Grumman’s Block 40 configuration RQ-4 Global Hawk has successfully completed its first flight. The two hour flight took the aircraft from Northrop Grumman’s manufacturing facility in Palmdale, California to Edwards Air Force Base, California. Designated AF-18, the Block 40 configuration of the high-altitude, long-endurance (HALE) unmanned aircraft system (UAS) will carry the Multi-Platform Radar Technology Insertion Program (MP-RTIP) active electronically scanned array radar that will help warfighters detect, track and identify stationary and moving targets.  Read More

The benefits of using hydrogen fuel cells to power UAVs have been shown by the Naval Research Laboratory (NRL) with its Ion Tiger UAV setting an unofficial flight endurance record of 26 hours and 1 minute while carrying a 5-pound payload. While taking advantage of hydrogen as a high-energy fuel, the electric fuel cell propulsion system onboard the Ion Tiger also boasts the low noise and signature of a battery-powered UAV.  Read More

Let’s say you want to go for a ride in your car, but you don’t feel like driving it. Or perhaps you want to drive your car, but you don’t want to go for a ride in it. These two seemingly contradictory scenarios are probably not what Kairos Autonomi had in mind when it developed the Pronto4 Agnostic Autonomy System. The Pronto4 is a drive-by-wire system that when installed in a vehicle, provides self-driving capability as well as remote control. The system is “agnostic” because it is a retrofit kit that the manufacturer claims can be installed in any steering-wheel based vehicle.  Read More

The largest fully-autonomous Unmanned Aerial Vehicle (UAV) ever to be built in the UK has completed initial flight trials in Woomera, South Australia. Built by BAE Systems for the UK Ministry of Defence (MOD) the Mantis is the company’s first genuine fly-by-wire, all-electric aircraft and is designed to execute its mission with a much-reduced need for human intervention by understanding and reacting to its environment. BAE said Mantis successfully completed a series of trials demonstrating its capabilities and the potential for large unmanned systems to carry out intelligence-gathering at long distances.  Read More

Students at the University of Maryland’s Clark School of Engineering have turned to nature to create a flying device that can hover and perform surveillance duties, and that could lead to applications for military and emergency services. The enigmatic maple tree seeds (or samara fruit) - and the unique spiraling pattern with which they glide to the ground - have intrigued children and engineers for decades. Now aerospace engineering graduate students have applied the seeds’ design to airborne devices and created what they believe to be the world's smallest controllable single-winged rotocraft.  Read More

Most Unmanned Aerial Vehicles (UAVs) employ a fixed wing design much like that of a traditional plane. But these designs offer limited maneuverability and payload capacity, require a runway to takeoff and land, and are unable to hover. Vertical Take Off and Landing (VTOL) UAVs get around these problems, usually by employing rotors like a helicopter. Now UK-based company AESIR has developed a VTOL UAV that has no external rotating parts, instead relying on a phenomenon known as the Coanda effect to generate lift.  Read More
