California-based aerospace company AeroVironment has developed some fascinating Unmanned Aircraft Systems (UAS) over the years, including the High Altitude Long Endurance Global Observer, a hummingbird-like nano air vehicle, and the hand-launched Wasp III reconnaissance platform. In 2008, the Defense Advanced Research Projects Agency (DARPA) awarded the company US$4.6 million in funding to develop a “perch-and-stare” aircraft, for use in military surveillance. Today, AeroVironment unveiled the result – the Shrike Vertical Take-off And Landing (VTOL) UAS.  Read More

DARPA's HTV-2 hypersonic vehicle, which prematurely splashed down in the Pacific Ocean on ...

The first – and perhaps only – video footage of the ill-fated second test-flight of DARPA’s Falcon Hypersonic Technology Vehicle 2 (HTV-2) has been released. Shot with a handheld camera by a crewmember aboard the Pacific Tracker, the first monitoring vessel able to visually track the HTV’s initial entry into the atmosphere, the video shows the HTV-2 hurtling across the sky on August 11 at Mach 20 before its “controlled descent” into the Pacific Ocean.  Read More

DARPA has confirmed the splash down of its unmanned Falcon Hypersonic Technology Vehicle (HTV-2) following the hypersonic vehicle’s second test flight on August 11. While a “controlled descent” generally refers to a human directing and guiding an aircraft to an unscheduled landing, safety systems onboard the HTV-2 kicked in after an anomaly was detected a little over nine minutes into the test flight and autonomously directed it into the ocean.  Read More

Lockheed Martin's Samarai Flyer monocopter micro air vehicle, alongside a maple seed

If you’ve ever watched a maple seed spiraling down from a branch, you may have marveled at how it looked like a tiny one-rotor-bladed helicopter. If you did, well, you weren’t the only one. In 2009, students from the University of Maryland’s Clark School of Engineering unveiled their remarkable samara (maple seed)-inspired micro air vehicle, which was billed as “the world’s first controllable robotic samara monocopter.” Flash forward to this Tuesday, and Lockheed Martin performed the first public flight of its similar Samarai Flyer, at the Association for Unmanned Vehicle Systems International conference in Washington, D.C.  Read More

The HTV-2 is designed to travel at speeds of Mach 20

On Thursday, DARPA's unmanned Falcon Hypersonic Technology Vehicle-2 (HTV-2) was launched from Vandenberg Air Force Base in California aboard an Air Force Minotaur IV rocket, which inserted the aircraft into the desired trajectory. After separation from the rocket, the vehicle transitioned to Mach 20 (approximately 13,000 mph/21,000 km/h) aerodynamic flight but a little after nine minutes of monitored flight the signal from the vehicle was lost with initial indications that the second test flight has ended in the same way as the first - with a crash into the Pacific Ocean.  Read More

Test firing of an LCITS rocket from an AH-1 Cobra helicopter

The Office of Naval Research (ONR) has unveiled a new weapons technology designed to give helicopters, such as the MH-60 and the AH-1 Cobra, the ability to combat the threat of a small boat swarm. The Low-Cost Imaging Terminal Seeker (LCITS) system equips existing unguided Hydra-70, 2.75-inch rockets with a low-cost guidance capability that allows pilots to essentially "fire-and-forget," thereby allowing them to engage multiple, fast attack seaborne targets in a shorter period.  Read More

The Chip Scale Atomic Clock is a matchbox-sized atomic clock, that uses one one-hundredth ...

Atomic clocks are one of those things that most of us have probably always thought of as being big, ultra-expensive, and therefore only obtainable by well-funded research institutes. While that may have been the case at one time, a team of researchers have recently developed an atomic clock that they say is one one-hundredth the size – and that uses one one-hundredth the power – of previous commercially-available products. It’s called the Chip Scale Atomic Clock (CSAC), and it can be yours for about US$1,500 ... a little more than what you might pay for a regular clock, but not bad for one that varies by less than a millionth of a second per day.  Read More

It would be scary to be chased by a military robot. It would also be scary to be chased by a cheetah. So, imagine what it would be like to have a military robotic cheetah sprinting after you. Such a scenario could one day be possible, as robotics company Boston Dynamics recently announced that America’s Defense Advanced Research Projects Agency (DARPA) has awarded it a contract to design and build such a ... critter. The contract also includes the creation of an agile, bipedal humanoid robot. It’s hard to say which one might ultimately be creepier.  Read More

Dr. June Medford, with some of her pollutant- and explosive-sniffing plants

There may come a day when certain plants in your workplace suddenly turn white, at which point everyone will run screaming from the building – those co-workers will have been right to do so, as the white plants indicated that a toxic gas was present. Before that scenario can take place, a little more work still needs to be done, and Colorado State University (CSU) biologist Dr. June Medford is doing it. Using a computer-designed detection trait, she is creating plants that stop producing chlorophyll when they detect pollutants or explosives in the air.  Read More

The XC2V must be designed around the tubular chassis found in the Local Motors Rally Fight...

In an effort to streamline the design and build process for manufacturing military vehicles, the Defense Advanced Research Projects Agency (DARPA) is enlisting the “power of the crowd”. Through the Experimental Crowd-derived Combat-support Vehicle (XC2V) Design Challenge, which asks entrants to conceptualize a vehicle body design for combat reconnaissance and combat delivery & evacuation, the agency is looking to pick the brains of not only armed service members and engineers, but also members of the public and others that usually have no way to contribute to military design.  Read More
