World's first green helicopter tested
"Rich and incredibly quiet sound, absolutely no noticeable vibrations in the flight, convincing structure with a great, new spring strut landing gear, and an extremely calm rotor plane," Alexander Zosel, managing director of developer E-volo, describes flights that lasted a total of about 20 minutes.
The VC200 has a proper cockpit for two, and is described as a vertical take-off and landing (VTOL) manned aircraft that doesn't quite fit into any traditional category of flying machine. It has 18 zero-emission, battery-powered electric motors for propulsion instead of the traditional combustion engines of helicopters. A frame and branching supports for rotors are made of carbon fiber help keep the weight down.
E-volo says the Volocopter VC200 can offer passengers a quiet, smooth, green ride. The vehicle is also easy to fly by joystick, and will have low operating and maintenance costs. The VC200 flew to a height of some 70 feet during its test flights, which were recorded in the video below, which is pretty noisy but that may be due to the camera position.
It can fly for about 20 minutes with current battery technology, but E-volo hopes that will improve to allow for flights of an hour or more. After additional testing and manned flights, the prototype will be used as the basis for series production in the coming years, said E-volo, calling the craft "the world's safest piece of air sport equipment."
"There are already numerous requests for the Volocopter from around the world," said Mr. Zosel. ■
