Pascal Chretien did what famed helicopter producer Sikorsky has n’t yet . He design , built and flew an untethered , manned electrical eggbeater . This disk - rig trajectory is like taking your toy dog outback dominance helicopter , boast it up to full size and aviate it .
With the financial support of Gallic company Solution F , Chretien spent 12 months building and testing his electric pearly . His biggest challenge in this process was overcoming the circumscribed power render by a assault and battery . If you call back about the baron difference between a battery - operate machine and its gas - powered counterpart , then you ’ll take account the difficulty of this challenge .
In its first public test flight , Chretien ’s chopper flew 2 minute , 10 endorsement and reached an altitude of one meter . This small , but important escape went down in the record book as the first liftoff of an untethered , man electrical helicopter . This is just the first for Chretien . He hopes to refine his design and set about a 4 - meter liftoff in the future . [ Gizmag ]
