World's First Twin-Seat Energy Efficient Helicopter Makes First Flight (Volocopter )

      The company named E-Volo based in Karlsruhe, Germany successfully made a test flight of Two- Seater Helicopter actually called Volocopter . Company says that it is safer, cleaner and simpler than normal helicopters. E-volo claims it is environment friendly and emission-free private helicopter. Instead of any combustion engine which are not environment friendly, it is powered by eighteen electrically driven rotors for propulsion.


     The maiden flight and first test flights were conducted in the dm-arena in Karlsruhe with the prototype of the 2-person VC200 on Sunday, November 17, 2013.

Here are some of the concepts explained by company itself :

What is a Volocopter?

    The Volocopter by e-volo is a completely novel, vertical take-off and landing (VTOL) manned aircraft, which cannot be classified in any known category. The fact that it was conceived of as a purely electrically powered aircraft sets it apart from conventional aircraft.

    Through the use of its many propellers, the Volocopter can take off and land vertically like a helicopter. A considerable advantage, apart from the simple construction without complex mechanics, is the redundancy of drives. This enables the safe landing of the volocopter even if some drives fail.


How Does the Volocopter Work?

    The controls work according to the fly-by-wire principle very easily by means of a joystick. As opposed to any other aircraft, the operation is child’s play. It takes off and lands vertically and the pilot pays little or no attention to the flight path angle, minimum speed, stall, mixture control, pitch adjustment and many other things which make conventional aviation so demanding.

    The propellers generate the entire ascending force, and by means of a selective change in rotary speed they simultaneously take care of the steering. Furthermore, as opposed to helicopters, no mechanical pitch control of the propellers is necessary whatsoever.

    The automatic position control and the directional control take place by means of several independent and mutually monitoring airborne computers which control the rotation speed of each drive separately.

An optional, additional pusher propeller enables an even faster flight.
