The
Wright Brothers
Wilbur was the older of the two brothers by four years.
Wilbur was born in 1867 on a farm near Millville, Indiana and Orville was born
in 1871 near Dayton, Ohio. As youngsters, Wilbur and Orville looked to their
mother for mechanical expertise and their father for intellectual challenge.
Milton, their father, brought them various souvenirs and trinkets he found
during his travels for the church. One such trinket, a toy helicopter-like top,
sparked the boys' interest in flying. In school, Wilbur excelled, and would have
graduated from high school if his family had not moved during his senior year. A
skating accident and his mother's illness and subsequent death kept him from
attending college. Orville was an average student, known for his mischievous
behavior. He quit school before his senior year to start a printing business.
The two brothers were very intellectual and smart, but both did not ever get
their high school diplomas. It just goes to show that even two of the best minds
in our history didn’t have to go to college or even finish high school to become
these great minds.
The first time Wilbur and Orville referred to themselves
as "The Wright Brothers" was when they started their own printing firm at the
ages of 22 and 18. Using a damaged tombstone and buggy parts, they built a press
and printed odd jobs as well as their own newspaper. In 1892, the brothers
bought bicycles. They began repairing bicycles for friends, then started their
own repair business. They opened up a bicycle shop in 1893, and three years
later, made their own bicycles called Van Cleves and St. Clairs. While nursing
Orville, who was sick with typhoid in 1896, Wilbur read about the death of a
famous German glider pilot. The news led him to take an interest in flying. On
May 30, 1899, he wrote to the Smithsonian Institution for information on
aeronautical research. Within a few months after writing to the Smithsonian,
Wilbur had read all that was written about flying. He then defined the elements
of a flying machine: wings to provide lift, a power source for propulsion, and a
system of control. Of all the early aviators, Wilbur alone recognized the need
to control a flying machine in its three axes of motion: pitch, roll, and yaw.
His solution to the problem of control was 'wing warping.' He came up with the
revolutionary system by twisting an empty bicycle tube box with the ends
removed. Twisting the surface of each 'wing' changed its position in relation to
oncoming wind. Such changes in position would result in changes in the direction
of flight. Wilbur tested his theory using a small kite, and it worked.
In
August of 1900, Wilbur built his first glider. He then contacted the U.S.
Weather Bureau for information on windy regions of the country. Reviewing the
list, he chose a remote sandy area off the coast of North Carolina named Kitty
Hawk, where winds averaged 13 m.p.h. He and Orville then journeyed to
Kitty Hawk
where they tested the 1900 glider. The following year, they tested a new and
improved glider with a 22-foot wingspan. A disappointing performance by the 1901
glider prompted the Wright brothers to construct a wind tunnel to test the
effectiveness of a variety of wing shapes. Using the results of the wind tunnel
experiments, they constructed their 1902 glider. Testing it at Kitty Hawk in
October, they met with success, gliding a record 620 feet. Once again they
returned to Dayton and began work on developing a propeller and an engine for
their next effort, a flying machine.
Immediately upon their return to
Dayton, they wrote to a number of automobile and motor builders, stating the
purpose for which they desired a motor, and asking whether they could furnish
one that would develop eight-brake horse power, with a weight complete not
exceeding 200 pounds. Most of the companies answered that they were too busy
with their regular business to undertake the building of such a motor for them;
but one company replied that they had motors rated at 8 h.p. according to the
French system of ratings, which weighed only 135 pounds, and that if the
brothers thought this motor would develop enough power for our purpose, they
would be glad to sell them one. After an examination of the particulars of this
motor, from which they learned that it had but a single cylinder of 4 inch bore
and 5 inch stroke, they were afraid that it was much overrated. Unless the motor
would develop a full 8 brake horse power, it would be useless for our purpose.
Finally they decided to undertake the building of the motor themselves. They
estimated that they could make one of four cylinders with 4 inch bore and 4 inch
stroke, weighing not over two hundred pounds, including all accessories. The
Wright Brothers only experience up to that time in the building of gasoline
motors had been in the construction of an air-cooled motor, 5 inch bore and 7
inch stroke, which was used to run the machinery of their small workshop. To be
certain that four cylinders of the size we had adopted (4" x 4") would develop
the necessary 8 horse power, they first fitted them into a temporary frame of
simple and cheap construction. In just six weeks from the time the design was
started, they had the motor on the block testing its power. The ability to do
this so quickly was largely due to the enthusiastic and efficient services of
Mr. C.E. Taylor, who did all the machine work in their shop for the first as
well as the succeeding experimental machines. There was no provision for
lubricating either cylinders or bearings while this motor was running. For that
reason it was not possible to run it more than a minute or two at a time. In
these short tests the motor developed about nine horse power. We were then
satisfied that, with proper lubrication and better adjustments, a little more
power could be expected. The completion of the motor according to drawing was,
therefore, proceeded with at once. The brothers then returned to Kitty Hawk to
begin construction and begin testing of the worlds first flying machine.
Just as the building was being completed, the parts and material for the
machines arrived simultaneously with one of the worst storms that had visited
Kitty Hawk in years. The storm came on suddenly, blowing 30 to 40 miles an hour.
It increased during the night, and the next day was blowing over seventy-five
miles an hour. In order to save the tar-paper roof, we decided it would be
necessary to get out in this wind and nail down more securely certain parts that
were especially exposed. When Orville ascended the ladder and reached the edge
of the roof, the wind caught under his large coat, blew it up around his head
and bound his arms till he was perfectly helpless. Wilbur came to his assistance
and held down his coat while he tried to drive the nails. But the wind was so
strong he could not guide the hammer and succeeded in striking his fingers as
often as the nails. The next three weeks were spent in setting the motor-machine
together. On days with more favourable winds they gained additional experience
in handling a flyer by gliding with the 1902 machine, which they had found in
pretty fair condition in the old building , where they had left it the year
before. Mr. Chanute and Dr. Spratt, who had been guests in the camp in 1901 and
1902, spent some time with the brothers, but neither one was able to remain to
see the test of the motor-machine, on account of the delays caused by trouble
which developed in the propeller shafts.
At twenty minutes after eleven Wilbur started on
the second flight. The course of this flight was much like that of the first,
very much up and down. The speed over the ground was somewhat faster than that
of the first flight, due to the lesser wind. The duration of the flight was less
than a second longer than the first, but the distance covered was about
seventy-five feet greater. Twenty minutes later the third flight started. This
one was steadier than the first one an hour before. Orville was proceeding along
pretty well when a sudden gust from the right lifted the machine up twelve to
fifteen feet and turned it up sideways in an alarming manner. It began a lively
sliding off to the left. He then warped the wings to try to recover the lateral
balance and at the same time pointed the machine down to reach the ground as
quickly as possible. The lateral control was more effective than he imagined and
before he reached the ground the right wing was lower than the left and struck
first. The time of this flight was fifteen seconds and the distance over the
ground a little over 200 feet.
Wilbur started the fourth and last flight at
just 12 o'clock. The first few hundred feet were up and down, as before, but by
the time three hundred feet had been covered, the machine was under much better
control. The course of the next four or five hundred feet had but little
mishaps. However, when out about eight hundred feet the machine began pitching
again, and, in one of the its darts downward, struck the ground. The distance
over the ground was measured and found to be 852 feet; the time of the flight 59
seconds. The frame supporting the front rudder was badly broken, but the main
part of the machine was not injured at all. They estimated that the machine
could be put in condition for flight again in a day or two.
And so it began,
the beginning of a new era in travel. The flight of this new machine would
change the lives of people throughout history. Without airplanes how would World
War II have ended up. Without airplanes, it would still be a very long journey
across the ocean in a boat. Without airplanes how could someone go see their
grandparents who live thousands of miles away. Airplanes changed the geography
of this world making it much easier to travel long distances and not to mention
much quicker. Airplanes today can carry hundreds of people to where ever they
want to go at descent fairs.
Flight changed history and geography forever
and we can compliment two men for that, Wilbur and Orville Wright, “The Wright
Brothers.” The Wright brothers is a name that everyone knows. People know what
the brothers did and how it affected them in years to come. If you ask anyone
who the Wright brothers are that anyone will know. This is how the Wright
brothers are such an important part of history and geography. A journey that
would have lasted two weeks before there were airplanes, now only takes a few
hours by plane.
