The Wright brothers, Wilbur (1867-1912) and Orville (1871-1948), were pioneers of aviation. Through experimentation with gliders and powered flights starting in 1900, they achieved the first controlled, powered and sustained heavier-than-air human flight on December 17, 1903. They continued developing their aircraft and conducting flight tests through 1905. Despite initial skepticism, they were eventually recognized for their achievements and innovations in aeronautics which revolutionized air travel.

3. Childhood of Wright Brothers
The Wright brothers were two of
seven children born to Milton Wright.
• Wilbur was born near
Millville, Indiana, in 1867
• Orville in Dayton, Ohio, in 1871
•In elementary school, Orville was
given to mischief and was once

expelled.
•Wilbur only completed his High School, he was not able to complete his
diploma.
•Orville Dropped out of High School after his junior year to start a printing
Business in 1889. A weakly newspaper called “West Side News”.

4. The Birth of the Invention
In 1878 their father brought them a “Toy”, the device was made of
paper, bamboo and cork with a rubber band to twirl its rotor, it was about
a foot long. The boys played with it all the time watching it flying around
in the hall until it Broke. The toy sparked an interest in the boys for one of
the greatest inventions in the history of Mankind.

5. Early career and research
•While working in the printing
business, the brother's found out the
craze for Bicycle’s in America .
•The Brother’s opened a repair and sales
shop in 1892 in the name of “The Wright
Cycle Exchange” which was later named
as “Wright Cycle Company”.
Wright-Bicycle-Shop
•They began Manufacturing there own
brand in1896.
•They used this endeavor to fund their
growing interest in flight.
•In the year 1899 the Brother’s began
there mechanical aeronautical
experimentation.

6. In the Quest of building something better
In July 1899 Wilbur put wing warping to the test by building and flying a
five-foot box kite in the shape of biplane.

The 1900 Glider.
•The brothers flew the gliders only a few days in the early autumn of 1900
at kitty Hawk.
•Wilbur was aboard while the gilder flew as the kite flew. Most of the kite
tests were unpiloted with sandbags or chains or sometimes a local boy as
onboard ballast

7. In the year 1901 gilders were build with
a much larger wing area.
50-100 flights were tested in July and
August .
The brothers were using “The Lift
Equation “ which was in existence for
almost a 100 years. Orville at Kitty Hawk with the 1901 glider

8. A Big Improvement
In the year 1902 the brothers took a
huge step forward and made basic wind
tunnel tests on 200 wings of many
shapes and airfoil curves, followed by
detailed tests on 38 of them. These
most crucial and fruitful aeronautical
experiments. 1901 glider flown by Wilbur & Orville

was able to make turns for the first
time using wing-warping and the
movable rudder.
On March 23, 1903 the
brothers applied there
patent for a “Flying
Machine” based on there
1902 gilder.

9. The movement of Truth
In the year 1903 the brothers built the
powered “Wright Flight 1”
At this time of the year the brothers
were having a 66% Success rate in
there attempts for a successful
flight. in addition to that the wind
tunnel experiments showed a
success rate of 75% on there
attempts and later had reached the First flight of the Wright Flyer
peak for 82-85% with the help of the I, December 17, 1903
modern wooden propellers.
The Wright/Taylor engine was a primitive version of modern fuel-
injection systems, having no carburetor or fuel pump. Gasoline was
gravity-fed into the crankcase through a rubber tube from the fuel tank
mounted on a wing strut.
The 12 Second flight lifted 120 feet above the watching world.

11. In 1904 the Wrights built the
Flyer II.
The flyer, Flight #85, flew
approximately 1,760 feet
(536 m) in 40 1/5
seconds, November 16, 1904.

Prairie, November 9, 1904
The test were made at “Huffman
Prairie” the place had lower air
density then “Kitty Hawk” which
made the takeoffs more difficult.
In the year 1905 the brothers build
the flyer III.

miles in 33 minutes 17 seconds; last

12. Handling the Critic’s
In 1906, skeptics in the European
aviation community had converted the
press to an anti-Wright brothers stance.
European newspapers, especially in
France, were openly derisive,
The Dayton Daily News reported
calling them “Bluffers” .

The Wright brothers made no flights at all in 1906 and 1907. They spent
the time attempting to persuade the U.S. and European governments that
they had invented a successful flying machine and were prepared to
negotiate a contract to sell such machines.
In May 22, 1906 they were finally granted a patent for their flying machine.
In early 1908 the brothers also agreed to a contract with a French
company.

13. Achievements.
•On October 7, 1908, Edith Berg, the wife of
the brothers' European business
agent, became the first American woman
passenger when she flew with Wilbur.
•Wilbur promised her that he would make his
first European flight the day her baby was
born which he did, August 8, 1908.
•On September 9, he made the first hour-long
flight, lasting 62 minutes and 15 seconds. Hart O. Berg the Wrights'
business agent, and Wilbur
•In January 1909 Orville and Katharine joined
him in France, and for a time they were the
three most famous people in the
world, sought after by royalty, the
rich, reporters and the public. The kings of
England, Spain and Italy came to see Wilbur
fly.
