'e-volo' personal multicopter


the 'e-volo' multicopter is a prototype personal transport vehicle, steerable via joystock and powered by sixteen propellers
to hover in the air. a team of german professionals-- physicist thomas senkel, programmer stephan wolf, and designer philipp
halisch, as well as alexander zosel-- have just completed the first prototype and test flight of the craft, which they imagine
for use towards entertainment purposes, aerial photography and inspection, and short-distance travel.

in 'e-volo', altitude, directional control, and balance are automatically managed by onboard computers, while the driver steers
by using a simple joystick. the designers note that the program could be integrated with GPS and obstacle detection systems
to enable unmanned flight. each of the vehicle's sixteen motors uses an off-the-shelf battery and is independently controlled,
easing maintenance and repairs.

the craft is energy and economically efficient, with a one-hour flight estimated to cost about 6 euros' worth of electricity.
redundancy engineering permits 'e-volo' to land safely even if up to four of its motors fail, and the vehicle can also be
protected by safety parachute. currently 'e-volo' should permit flights of up to 20 minutes, but by integrating a hybrid gas
system, or as the capacity of batteries increases, the engineering team suggests that flights could last over an hour.
