Falx Air Vehicles are making a breakthrough in aircraft innovation, they are planning to use hybrid-electric motor and inbuilt solar arrays rather than fuel. Falx has showed the full-size prototype as early as the Farnsworth air show this year, a compact single and double-seater tilt-rotor aircraft which targeted only use 10 liters of fuel per hour airborne. Using aerospace-certified composite materials, the single seater weighs in at only 350kg, with the twin-seat version weighing 405kg.
Falx claims the battery packs powering the Falx will be the latest fast-charge battery systems the USA has to offer, but no further details are available. The batteries will be charged both by inbuilt solar relays and through the use of a small 100hp combustion engine that drives a lightweight, brush-less generator. Noise and thermal image will thus be kept to a minimum, enhancing the craft’s stealth abilities. The twin electric engines eliminate a lot of complex machinery in traditional tilt-wing craft, such as drive-shafts, hydraulics and gearboxes.
