Wright Brothers <ul><li>The creators of the first plane that could really fly. </li></ul><ul><li>A History that won’t be forgiven. </li></ul><ul><li>And the start of a new age. </li></ul>Orville Wilbur
Their Chilhood <ul><li>The Wright brothers were two of seven children born to Milton Wright (1828–1917) and Susan Catherine Koerner (1831–1889). Wilbur Wright was born near Millville, Indiana in 1867; Orville in Dayton , Ohio in 1871. The brothers never married. The other Wright siblings were named Reuchlin (1861–1920), Lorin (1862–1939), Katharine (1874–1929), and twins Otis and Ida (born 1870, died in infancy). In elementary school, Orville was given to mischief and was once expelled. Brethren in Christ , brought home a toy "helicopter" for his two younger In 1878 their father, who traveled often as a bishop in the Church of the United sons. The device was based on an invention of French aeronautical pioneer Alphonse Penaud . Made of paper, bamboo and cork with a rubber band to twirl its rotor, it was about a foot long. Wilbur and Orville played with it until it broke, then built their own. In later years, they pointed to their experience with the toy as the initial spark of their interest in flying. </li></ul>
The Gliders, Their Invention <ul><li>The Wrights based the design of their first full-size glider on the work of their recent predecessors, chiefly the Chanute-Herring biplane hang glider ("double-decker," as the Wrights called it), which flew well in the 1896 experiments near Chicago; and aeronautical data on lift that Lilienthal had published. The Wrights designed the wings with camber , a curvature of the top surface. The brothers did not discover this principle, but took advantage of it. The better lift of a cambered surface compared to a flat one was first discussed scientifically by Sir George Cayley . Lilienthal, whose work the Wrights carefully studied, used cambered wings in his gliders, proving in flight the advantage over flat surfaces. The wooden uprights between the wings of the Wright glider were braced by wires in their own adaptation of Chanute's modified "Pratt truss," a bridge-building design he used in his 1896 glider. The Wrights mounted the horizontal elevator in front of the wings rather than behind, apparently believing this feature would help avoid a nosedive and crash like the one that killed Lilienthal. (Later, when Brazilian aviation pioneer Santos-Dumont , flew his 14-bis in Paris in 1906, French newspapers dubbed the tail-first arrangement a " canard ", due to the supposed resemblance to a duck in flight.) Wilbur incorrectly believed a tail was not necessary, and their first two gliders did not have one. According to some Wright biographers, Wilbur probably did all the gliding until 1902, perhaps to exercise his authority as older brother and to protect Orville from harm. </li></ul>
The Glider Statics <ul><li>This where the glider statics to make it fly, on the different years the desings where different. </li></ul><ul><li>They updated and redesigned them to make the gliders fly better every time . </li></ul>
The Lift Equation <ul><li>This was the equation they made to make the Glider fly. </li></ul>

The Wright Flyers <ul><li>After making the Gliders, they put an engine and desinged the Wright Flyer. After that one they made 2 more versions. </li></ul>Wright Flyer I Wright Flyer II Wright Flyer III
Patenting the Glider <ul><li>Their 1903 patent application, which they wrote themselves, was rejected. In early 1904 they hired Ohio patent attorney Henry Toulmin, and on 22 May 1906 they were granted U.S. Patent 821393 for a "Flying Machine". </li></ul><ul><li>The patent illustrated a non-powered flying machine—namely, the 1902 glider. </li></ul>
The company <ul><li>The Wright Company was incorporated on 22 November 1909. The brothers sold their patents to the company for $100,000 and also received one-third of the shares in a million dollar stock issue and a 10 percent royalty on every airplane sold. With Wilbur as president and Orville as vice president, the company set up an airplane factory in Dayton and a flying school/test flight field at Huffman Prairie; the headquarters office was in New York City. </li></ul>
Problems, and more problems <ul><li>They had a lot of problems, apart from crashes. They had a lot of problems with the patent of the Flyers, since a man called Glenn Curtiss sold a very similar “plane” like Wright’s but with ailerons (I put the link to Wikipedia), so they made a lawsuit. Anyway in 1914 they won it, but earlier in 1912 Wilbur has already died of thypoid fever. </li></ul>Photo of the crash
Finally <ul><li>Wilbur’s death. </li></ul><ul><li>He became ill on a trip to Boston in April 1912. After returning to Dayton, he was diagnosed with typhoid fever. He died, age 45, in the Wright family home on 30 May. His father Milton wrote about Wilbur in his diary: "A short life, full of consequences. An unfailing intellect, imperturbable temper, great self-reliance and as great modesty, seeing the right clearly, pursuing it steadfastly, he lived and died.“ </li></ul><ul><li>Orville’s death. </li></ul><ul><li>Orville died in 1948 after his second heart attack, having lived from the horse-and-buggy age to the dawn of supersonic flight. Both brothers are buried at the family plot at Woodland Cemetery, Dayton, Ohio. </li></ul>
