Eco Factor: UAV helicopter powered by an electric hybrid engine.
In a bid to green aviation, Falx Air has unveiled the final design overview of its hybrid electric coaxial helicopter UAV. The UAV is intended to be powered by an advanced fast charging battery systems that are being developed in the U.S. Keeping the weight of the aircraft under control had to be a priority, which the company hopes to implement by developing the airframe from aerospace certified composite materials.
The UAV would be able to lift a maximum of 70kg of cargo and can also be used for long duration surveillance. The UAV generates electricity by using a small rotary engine that drives a permanent magnet generator. In the event of a failure of the generator, the aircraft can make use of a bank of batteries for returning to base. Being fuel-efficient the generator consumes less than 10 liters of fuel hourly, which charges the battery bank as well.
The aircraft consists of two sets of three high torque motors, which are mounted along the length of the main shaft. This system is capable of providing a safe landing even if each motor set loses two motors. The company claims that 100% electricity powered helicopters are practically possible, but would have to make use of technology that’s still a couple of years away from development.
