Flying High with the Flick of a Joystick 用搖桿翱翔天際
by Leigh Goldberg
The e-volo multicopter takes personal travel to new heights.
Who wouldn't like to walk out of their house, step into their own vehicle, and fly off into the sky Now, with the _(1)_ of a personal
helicopter, a team of German professionals are close to making this happen.
The e-volo
multicopter is
not your average helicopter
by any means. First, it doesn't have just one
propeller. Instead, it has
a total of 16. Four are _(2)_ placed on each of the four
metallic arms
radiating out from the pilot's seat. Second, the
uncovered ultralight aircraft weighs around 80 kilograms and can carry a
load equal to its own weight. Third, the e-volo is _(3)_ with an almost completely
automatic on-board navigation system. The system manages everything from _(4)_ to
altitude to balance. The multicopter itself is controlled entirely with a simple video game joystick. Finally, what makes this personal
transport vehicle _(5)_ the typical helicopter is that it is powered
solely by
off-the-shelf lithium-ion batteries. Currently, the e-volo's flight time is _(6)_ to 20 minutes. The creators can _(7)_ that to more than an hour with the
integration of a
hybrid gas system or increased battery
capacity.
Recently, the engineering team _(8)_ completed a
manned flight of their e-volo multicopter
prototype. The _(9)_ flight lasted one minute and 30 seconds, with the vehicle
taking off,
hovering, and landing. The design team is now
looking into e-volo's _(10)_
applications, including emergency rescue, sightseeing, and
aerial photography and
surveillance. Without harmful
exhaust fumes or
excessive noise, the eco-friendly e-volo multicopter is definitely making the possibility of personal flight for the ordinary person
a dream come true.
