The Wright Stuff
On August 8, 1908, at a racetrack outside Paris, Wilbur Wright executed
what was, for him, a routine flight: a smooth take-off banking into a couple of
tight circles, ending in a perfect landing. The flight took less than two
minutes, but it left spectators awestruck. While the combined talents of Wilbur
and Orville Wright had produced the first plane capable of controlled flight ,
their distrust of others had almost cost them the credit for their invention.
Now, having proved to the public that they had mastered the sky, the reserved
brothers from the small town of Dayton, Ohio, became world celebrities.
Theirs is a quintessential American story of two midwestern boys who believed
they could break the barrier of the air, succeeding where others with
government grants and engineering educations had failed. Their remarkable
breakthroughs in design and engineering shaped the course of the twentieth
century.
The Wright brothers seemed like the most ordinary men in the world, but they
were brilliant, self-taught inventors who made a formidable team: Orville was
the born engineer, Wilbur the visionary.
The brothers' partnership started after a hockey accident seriously injured
18-year-old Wilbur, leaving him in a state of depression for nearly two years.
Younger brother Orville, who "was always very optimistic," as their
grand-nephew, Wick Wright, tells THE AMERICAN EXPERIENCE, finally coaxed Wilbur
out of the house and into his printing business.
By 1892, Orville and Wilbur had opened a bicycle shop. The bicycle had become a
national craze and represented the cutting edge in technology. The shop was the
perfect laboratory for the Wrights to develop engineering skills,
and the brothers were soon hand-crafting their own. But they grew restless and
Wilbur, now 30, was anxious to make his mark in the world. "The boys of the
Wright family are all lacking in determination and push," he lamented in a
letter. "None of us has, as yet, made particular use of the talent in which he
excels other men."
Wilbur and Orville followed with interest the progress of the world's inventors
like American Samuel Langley and German Otto Lillienthal, who were trying to
develop a flying machine. In a letter to Langley, director of the Smithsonian
Institution, Wilbur wrote, "I believe that simple flight at least is possible
to man. I am an enthusiast, but not a crank. I wish to avail myself of all that
is already known and then if possible add my bit." Wilbur had no trouble
convincing Orville to work with him on the invention.
The brothers reasoned that flight depended on three concepts: the shape of the
wings, a means of powering the plane, and control. Others had focused on the
first two problems, but the Wrights knew from riding bicycles that control was
the key. Watching birds in flight, Wilbur reasoned that control lay in the way
birds twisted their wing tips. Translating the idea, he built a box kite and
braced the wings in such a way that they could be twisted in opposite
directions to make the kite bank and turn. This principle, which the Wright
brothers called "wing warping," was a revolutionary break-through.
In 1900 they built a full-size, piloted version of a box kite and tested its
control mechanisms at Kitty Hawk, North Carolina, where the winds are steady
and sandy slopes made for soft landings. The prototype showed some promise. The
following year, they went back to Kitty Hawk, as they would for the next three
years.
"One of the core aspects of their ability was a great facility to literally
visualize," says Peter Jakab, a historian with the National Air and Space
Museum, "literally see in their mind's eye a mechanical device, move components
of it around, or transfer mechanical devices from one technology to the
airplane and make them work."
The brothers approached each problem methodically, keeping meticulous notes on
the variations and results of each test. They would allow no guesswork, no
"hunt and peck" approach to problem solving that was the standard in the world
of 19th century inventions. After reviewing their work, the brothers realized
the standard wing design data they relied upon was flawed and came up with an
ingenious plan: They created a small wind tunnel and used miniature wings,
built to scale, to determine the best wing shape for the greatest lift. The
Wrights, for the first time, produced accurate aerodynamic tables.
With this new data, they built a glider with wings that produced enough lift;
they also added a hinged tail rudder to increase the pilot's control. They made
their third trip to Kitty Hawk in the summer of 1902. The glider
succeeded--they had at last managed to glide through the air with control.
Their next task was to turn their glider into an airplane.
With the help of a mechanic in the bike shop, the brothers built a small
engine. Designing the propeller was harder, but here, too, Orville and Wilbur
made another remarkable breakthrough. They realized the propeller worked like a
wing, but instead of lifting the craft, it pulled the plane forward.
On December 17, 1903, on their fourth trip to Kitty Hawk, with a local
fisherman present to photograph the event, Orville and Wilbur realized their
dream, making four flights that historic day--the longest lasted fifty-seven
seconds and traveled 852 feet.
The Wrights' work had inspired other plane developers--particularly the French.
The brothers had applied for a patent in 1902, but were turned down. Fearful of
being copied, they stubbornly refused to fly their machine--even when they were
finally awarded a patent--until they received a contract for the purchase of a
flying machine. Doubts about their ability had begun to surface: newspapers
vilified the brothers as "bluffers"; meanwhile, other inventors were closing
in. By early 1908, French aviator Henri Farman was flying his own machine. The
craft lacked control, but it was flying. The French were convinced that they
had conquered the air.
Finally, in 1908, the Wrights' claim reached President Theodore Roosevelt, and
the brothers signed a deal for $25,000 to build and fly one of their machines
for the US Army Signal Corps. A French deal soon followed. Later that year,
when Wilbur finally made his demonstration flight around a racetrack in France
before a small crowd of spectators, the French realized the Wright brothers had
moved far beyond other aviators.
Once the Wrights had successfully marketed their invention, they returned to
Ohio to manufacture airplanes. Orville managed the business while Wilbur took
numerous patent infringers to court. In 1912, Wilbur became ill with typhoid on
a business trip to Boston. He returned to the family home and died there three
weeks later at the age of 45.
After Wilbur's death, Orville sold the business for $1 million and retired. He
outlived Wilbur by more than 30 years, dying from a heart attack at the age of
76.
