Kitty
Hawk, Part III

President/Editor, StocksandNews.com
I apologize that this has developed
into a rather dysfunctional series on the Wright brothers,
but the weather I ran into last week while visiting
the Kitty Hawk, North Carolina area dictated that
I change the schedule a bit.
In
part I of our series I touched on other events taking
place in 1903, the year in which Kitty Hawk was witness
to the first flight, as well as the role of Samuel
Langley in the controversy that soon surrounded the
Wright brothers achievement. Part II went back and
listed some of the more important dates in history
as far as the search for human flight was concerned.
Of
course I should have reversed I and II, but oh well?we
continue.
I
only touched briefly on the early years of Orville
and Wilbur in part I and having now had the chance
to do more research, I realize this warrants more
discussion.
Wilbur
(4/16/1867-5/30/1912) and Orville (8/19/1871- 1/30/1948)
were the 3rd and 6th children born to Milton and Sara
Wright. Milton founded a radical offshoot of the Church
of Christ ("Old Constitution"), though it was actually
tamer than it sounds. Having traveled a ton to spread
the word, Milton and family eventually settled in
Dayton, Ohio.
Wilbur
and Orville were very curious kids growing up, yearning
to learn more about the world around them, and they
were also most appreciative of their upbringing. Orville
once wrote:
"(We)
were lucky enough to grow up in an environment where
there was always much encouragement to children to
pursue intellectual interests; to investigate whatever
aroused our curiosity." [Source: "First Flight: The
Wright Brothers and the Invention of the Airplane,"
Tom D. Crouch?*This is the primary source for this
column.]
Sister
Katharine added, "No family ever had a happier childhood
than ours had."
Orville
and Wilbur were exceedingly close. Wilbur:
"From
the time we were little children, my brother Orville
and myself lived together, played together, worked
together and, in fact, thought together?Nearly everything
that was done in our lives has been the result of
conversations, suggestions and discussions between
us."
But
neither officially graduated from high school, though
it also needs to be pointed out that in those days
high school was far tougher than it is today. Wilbur
did have plans to study at Yale, but he suffered a
serious injury playing a form of ice hockey when the
stick smashed into his mouth. For the next 3 years
he was a semi-invalid and had to deal with depression.
Meanwhile, Orville only finished 11th grade, after
which he decided to set himself up as a printer in
1889 following the death of their mother.
At
about the same time, though, the bicycle craze was
sweeping Dayton and the brothers (Wilbur having finally
recovered from his injury) decided to get into the
business in 1892, opening up a shop where they not
only repaired bicycles but designed their own models
starting in 1895.
The
Wright brothers began to draw parallels between riding
a bike and flight. The key was control and they approached
the invention of the airplane knowing two things:
"The machine would have to be controllable and, like
a child learning to ride a bike, they would have to
teach themselves to fly it." [Crouch]
Others
around the world were drawing the same conclusions
at this time, linking the bicycle to aviation. In
June 1896, the editor of the Binghamton (NY) Republic
made this prescient comment concerning the invention
of a heavier-than-air flying machine and the role
of bicycle designers.
"The
flying machine will not be in the same shape, or at
all in the style of the numerous kinds of cycles,
but the study to produce a light, swift machine is
likely to lead to an evolution in which wings will
play a conspicuous part." [Crouch]
Another
fellow, James Howard Means, wrote, "To learn to wheel
we must learn to balance. To learn to fly one must
learn to balance." [Crouch]
Well,
it just so happened that the manufacturing process
for a bicycle was perfect for the Wright brothers
and their quest to design an aircraft. The kinds of
precision crafted metal pieces that they were making
for the two-wheeler could be used for their flying
machine. The two also realized that just as a bicycle
rider learned to internalize the process of riding
one, so man would eventually learn to master the motions
required to control a plane.
One
of the first inspirations for the brothers was the
German experimenter Otto Lilienthal, who published
perhaps the definitive book on aeronautics for his
time back in 1889. Lilienthal completed 2,000 flights
on 18 different gliders between 1890 and his death
in a glider crash in 1896 and his demise had a profound
effect on Wilbur and Orville. Wilbur explained:
"The
brief notice of his death that appeared in the telegraphic
news of that time aroused a passive interest which
had existed from my childhood."
The
brothers wrote the Smithsonian Institution in Washington
for information on the printed works that existed
on the topic of aeronautics and the Smithsonian's
secretary, Samuel Langley, who was already working
himself on the problem (see part I), was helpful in
passing along recent material.
The
Wrights were great at analyzing the problems of others
and they concluded that the invention of the airplane
required: "wings developing sufficient lift to support
the weight of the machine and pilot; an engine powerful
enough to propel the craft to flying speed; and a
means of controlling the machine in the air." [Crouch]
The
key, again, was the problem of control. Wilbur explained,
"The?equilibrium had been the real stumbling block
in all serious attempts to solve the (issue) of human
flight, and that this problem of equilibrium in reality
constituted the problem of flight itself." [Crouch]
Now
before I continue I need to apologize because we're
going to have to get technical here in closing part
III of our story, but it's the only way to properly
paint the picture. I also need to teach myself, so
I'm dragging you along for the ride.
As
author Tom Crouch describes, one evening in July 1899,
Wilbur was working in the bicycle shop when he began
fiddling with a long, slender, inner-tube box.
"When
he held the ends of the box and twisted his hands
gently in opposite directions, a helical (ed. spiral)
twist moved back and forth across the box. If the
horizontal faces of the box were the two wings of
a biplane, and the vertical faces were the struts
supporting and separating the wings, he reasoned,
a twist in either direction would increase the angle
of attack (the upward tilt of the wing relative to
the airflow), and thus the lift, on one side and decrease
it on the opposite side. The pilot of such an aircraft,
provided with suitable controls, could balance the
wings with ease, or bank for a turn. It was the technique
that would come to be known as wing-warping - the
precursor of ailerons on today's aircraft - and it
was one of the Wrights' most brilliant and original
contributions to aeronautics."
Wilbur
then built a model out of bamboo to demonstrate the
principals to Orville.
The
three main issues in solving the problems of flight
involved control, lift and propulsion; or 'pitch,'
'yaw,' and 'roll.'
Picture
a little Cesna plane. The pitch is the 'elevator'
in the rear, below the 'rudder' (which is responsible
for yaw), and the roll is controlled by 'ailerons,'
these being located on the wings (the flaps you see
going up and down). [On the Wright brothers first
plane, the elevator was out front and the pilot controlled
the ailerons manually, while lying down on the wing.]
Just
a further word on 'roll'; Orville and Wilbur had observed
that a soaring turkey vulture "steadied itself or
turned by twisting up a wingtip to roll its body,
(so) the Wrights designed a wing- warping system for
the Flyer. Moving the hip cradle warped the trailing
edge of one wing up and the other down, rolling the
aircraft to control it."
OK,
now that I've confused some of you, and I haven't
supplied you with a simple diagram to help describe
the processes, we'll finish (I promise) our story
next week with the final days in December 1903 and
the first flights (they had four on December 17).
This coming December, when the news is full of stories
on this amazing feat that changed the world, you'll
thank me for the head start.
