Adrian Nicholas Proves Da Vinci
Chute Works
Posted Sunday, July 9, 2000
More than 500 years after Leonardo da Vinci
sketched his design, a Briton has proved that the renaissance genius
was indeed the inventor of the first working parachute.
Adrian Nicholas, a 38-year-old skydiver from London, fulfilled
his life's ambition to prove the aerodynamics experts wrong when
he used a parachute based on Da Vinci's design to float almost one
and a half miles down from a hot air balloon. Ignoring warnings
that it would never work, he built the 187lb contraption of wooden
poles, canvas and ropes from a simple sketch that Da Vinci had scribbled
in a notebook in 1485.
And at 7am on Monday, over the Mpumalanga province of South Africa,
Mr Nicholas proved in a 7,000ft descent that the design could indeed
be looked upon as a prototype for the modern parachute.
Yesterday he said: "It took one of the greatest minds who
ever lived to design it, but it took 500 years to find a man with
a brain small enough to actually go and fly it.
"All the experts agreed it wouldn't work - it would tip over
or fall apart or spin around and make you sick - but Leonardo was
right all along. It's just that no one else has ever bothered trying
to build it before."
Mr Nicholas, who holds the world record for the longest free fall
at just under five minutes, was strapped into a harness attached
by four thick ropes to a 70ft square frame of nine pine poles covered
in canvas. He was then hoisted by a hot air balloon to 10,000ft
above ground level.
The balloon dropped altitude for a few seconds, to enable the parachute
to fill with air, and the harness was released, allowing the parachute
to float free.
Surrounded by two helicopters and two parachutists, Mr Nicholas
fell for five minutes as a black box recorder measured the 7,000ft
descent, before he cut himself free and released a conventional
parachute. The Da Vinci model, which has more in common with sail
technology than with the modern-day parachute, made such a smooth
and slow descent that the two accompanying parachutists had to brake
twice to stay level with it. It had none of the sudden plunges and
swinging associated with modern parachutes.
After being cut free, the contraption floated to the ground with
only minor damage on impact.
Mr Nicholas, a former broadcaster who has made 6,500 skydives,
said: "The whole experience was incredibly moving, like one
of those great English boy's own adventures. I had a feeling of
gentle elation and celebration. It was like floating under a balloon.
"I was able to stare out at the river below, with the wind
rattling through my ears. As I landed, I thanked Leonardo for a
wonderful ride."
The contraption, which has seen two aborted attempts to fly over
Salisbury plain in Wiltshire earlier this year, was built by Katarina
Ollikainen, Mr Nicholas's Swedish girlfriend.
Following Da Vinci's design for a four-sided pyramid covered in
linen and measuring 24ft square at the base, Ms Ollikainen used
only tools and materials that would have been available in the 15th
century, apart from some thick balloon tapes to stop the canvas
tearing.
Although there was little demand for parachutes in the 15th century
- and it was the Frenchman Louis-Sebastien Lenormand who was always
credited with the first parachute jump after he leapt from a tree
with the help of two parasols - Da Vinci gave specific instructions
for his design.
