Siemens' world-record electric aircraft motor punches above its weight

By - April 20, 2015 7 Pictures
Researchers at Siemens have created a new prototype electric motor specifically designed for aircraft that weighs in at just 50 kg (110 lb) and is claimed to produce about 260 kW (348 hp) at just 2,500 RPM. With a quoted power five times greater than any comparable powerplant, the new motor promises enough grunt to get aircraft with take-off weights of up to 1,800 kg (2 ton) off the ground. Read More

Freightliner SuperTruck shows other transport trucks how efficiency is done

By - April 6, 2015 3 Pictures
Back in 2009, the US Department of Energy issued its SuperTruck Challenge. The program provided funding for truck manufacturers to design and build a prototype vehicle that was at least 50 percent more freight-efficient than a baseline 2009 truck. Daimler Trucks North America recently unveiled its response – the Freightliner SuperTruck. It goes beyond the 50 percent figure, with a claimed efficiency increase of 115 percent. Read More

Could this 18-motor wing be the future of electric aircraft?

By - March 18, 2015 3 Pictures
It might look like it was designed by a six-year-old, with 18 motors crammed onto a too-thin wing, but the Hybrid-Electric Integrated Systems Testbed (HEIST) experimental wing demonstrator could be the future of electric aircraft. A key component of NASA'S Leading Edge Asynchronous Propeller Technology (LEAPTech) project, it is designed to test whether electric propulsion can allow for a tighter wing design leading to greater efficiency and safety.

GloW glider/microlight hybrid combines the best of both aircraft

By - March 16, 2015 6 Pictures
UK-based ProAirsport has developed a hybrid microlight/glider with electrically powered wheels used for taxiing and takeoff, and a jet turbine for climbing and cruising. During flight, the engine can be turned on and off with the flip of a switch, allowing the aircraft to be flown as either a microlight or glider. Unlike typical microlights and self-launching gliders, ProAirsport's GloW is propeller-free. Read More
