Robo-Bat: mini spy-plane of the future?
Image Gallery (2 images)
Micro Air Vehicles (MAVs) undoubtedly have the potential to revolutionize both military and civilian surveillance operations, and the quest to find the most efficient design for these airborne spies of the future is leading to all kinds of radical platforms being investigated. Several are derived from nature, where evolution has produced designs that out-strip the performance and efficiency of humanity's aerial achievements on a proportional scale. Even extinct examples like the pterodactyl are not immune from this scrutiny, but in this case, the inspiration comes from the only mammal naturally capable of flight - the bat. Read More

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. Read More

AeroVironment to continue Nano Air Vehicle development
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).

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.
