• after a request from the Israeli Electric
Company for a system that could
wash and clean power-line insulators.
One of the main problems with
washing these insulators is that it is
too dangerous to wash them from the
ground unless you disconnect the
power lines, which causes a power
outage. One solution is to tackle them
from the air.
In just six weeks, AD&D devel-
oped a nine-meter long water gun
made from advanced composite mate-
rials that fires high-pressure water at
the insulators from a modified heli-
copter. Since then, several helicopters
have been modified, and the system
has accumulated thousands of line
hours.

AD&D went on to develop other
helicopter modifications such as a bal-
cony that enables technicians to stand
outside a helicopter cab and perform
maintenance tasks on power lines; a
system for threading steel wires
between pylons; and a robotic
machine that mounts plastic spheres
on power lines.
Other successful projects include
an advanced solar-powered high-alti-
tude airplane; a miniature field control
computer; and a number of revolu-
tionary high-speed propellers.
AD&D's latest device is a flying
machine called the Hummingbird,
which enables individuals to fly up to
10,000 feet at speeds of up to 60
km./h. A four-engine, 1.9-meter circu-
lar platform with a waist-high cage to
stand in, the Hummingbird can be
navigated simply by shifting your
body in the direction you want to go.
Like a helicopter, it goes straight up
on take-off. "It shouldn't be more dif-
ficult than riding a bike," says Yoeli.
The idea was born in the US in the
1950s. American scientists developed a
similar vehicle which was never com-
mercialized because it proved too dan-
gerous to fly. With today's advanced
technology, Yoeli is convinced that the
problems encountered in the past have
been eradicated. The platform should
be ready for a test flight before the
end of the year.
