Solar Technology Improves UAS Flight Duration
During a keynote at the small unmanned systems business expo in San Francisco, California, on July 25th., Alta Devices’ CEO Christopher Norris explained that small unmanned aircraft Systems (UAS) are no longer constrained to short-range or limited flight times and are now able to fly as long as the sun is shining.

Pratt & Whitney Powers X-47B Carrier Launch
Pratt & Whitney’s F100-PW-220U engine and exhaust system recently powered the first ever carrier-based catapult launch, touch and go, and arrested landing of Northrop Grumman’s X-47B flight test aircraft for the U.S. Navy’s Unmanned Combat Air System Carrier Demonstration (UCAS-D) programme. Continue reading
Hybrid Electric Planes Development Progresses
Last month Siemens and EADS demonstrated a new gas-electric vehicle capable of carrying two people and their luggage 900 kilometers—roughly the distance from New York to Detroit—between refuels and recharges. The prototype was not a car, but a small two-seater airplane. Continue reading

New All-Solid Sulphur-Based Battery Outperforms Lithium-ion Technology
Scientists at the Department of Energy’s Oak Ridge National Laboratory have designed and tested an all-solid lithium-sulphur battery with approximately four times the energy density of conventional lithium-ion technologies that power today’s electronics. Continue reading
Solar-Powered OctoCopter
Ecilop Solar (Ecilop-8) is controlled as a quad-copter, 8 rotors are connected pair-wise. There is no onboard battery. To configure controllers inside a building, the user connects an external battery. To restart the controller in sunlight, the user bridges the power leads. The vehicle remains airborne because of ground effect and automatically maintains a horizontal attitude. Continue reading
Aurora Electric Ducted Lift Fan Completes High Powered Thrust Tests for DARPA
Aurora Flight Sciences along with partners ThinGap and Trust Automation are answering the need for safe, high power density electric lift fans, with specific interest in vertical takeoff and landing (VTOL) air vehicle applications. Continue reading
