General

The Wright brothers, Orville and Wilbur, were two Americans who are generally credited with inventing and building the world's first successful aeroplane and making the first controlled, powered and sustained heavier-than-air human flight, on December 17, 1903.

They are also officially credited worldwide through the Fédération Aéronautique Internationale, the standard-setting and record-keeping body for aeronautics and astronautics, as "the first sustained and controlled heavier-than-air powered flight."

In the two years afterward, the brothers developed their flying machine into the first practical fixed-wing aircraft. Although not the first to build and fly experimental aircraft, the Wright brothers were the first to invent aircraft controls that made fixed wing flight possible.

The brothers' fundamental breakthrough was their invention of three-axis control, which enabled the pilot to steer the aircraft effectively and to maintain its equilibrium. This method became standard and remains standard on fixed wing aircraft of all kinds. From the beginning of their aeronautical work, the Wright brothers focused on unlocking the secrets of control to conquer "the flying problem," rather than developing more powerful engines as some other experimenters did. Their careful wind tunnel tests produced better aeronautical data than any before, enabling them to design and build wings and propellers more effective than any before. Their U.S. patent 821,393 claims the invention of a system of aerodynamic control that manipulates a flying machine's surfaces.

They gained the mechanical skills essential for their success by working for years in their shop with printing presses, bicycles, motors, and other machinery. Their work with bicycles in particular influenced their belief that an unstable vehicle like a flying machine could be controlled and balanced with practice.

From 1900 until their first powered flights in late 1903, they conducted extensive glider tests that also developed their skills as pilots. Their bicycle shop employee Charlie Taylor became an important part of the team, building their first aircraft engine in close collaboration with the brothers.

Inevitably a certain amount of inaccuracy and mythology surrounds the story of the Wright brothers' achievements. An aeronautical engineer, Joe Bullmer, studied the facts and claims in depth, and set out to present a more accurate history and to put the developments into proper histroical context in a book published in 2009.[1]

Chronology

Wilbur was born 1867 and Orville born in 1871 at Dayton, Ohio, the sons of Bishop Milton Wright of the Church of the United Brethren in Christ and his wife Susan Koerner who was from a family of carriage and wagon builders. They also had Reuchlin born 1861, Lorin born 1862 and Katharine born 1874.

1871 April. Family moved to Hawthorne street, Dayton

1877 First interest in flying aroused by a toy helicopter based on a design by Alphonse Penaud

1885 Wilbur aged 18 has a sports accident and sustained injuries to his face and the loss of many of his teeth. The operations that followed caused him a period of depression and he was only rescued from this state two years later when Orville aged 16 asks for his help in building a printing press

1889 Susan Wright, their mother dies

1889 Orville worked for a printer for about one year but then left and went in to the cycle business

1892 They opened their first cycle shop at West Third Street and were soon producing the ‘Wright Special’ at $18

1899 The brothers started an active interest in aviation. In May they write to the Smithsonian Institute asking about publications on flying and were sent copies of the ‘The Aeronautical Journal’ by James Means

1899 July. Wilbur first has the concept of wing warping as a means of controlling roll

1899 Built kite with 5 feet wing span and 195 sq. ft. area to successfully prove the wing warping theory

1900 May. Write to Octave Chanute describing the wing warping and receive an encouraging reply.

1900 They contact the US Weather Bureau to find suitable site for flight trials and decide upon Kitty Hawk in North Carolina. They contact William Tate the local postmaster.

1902 October. They carry out some one thousand flights in the month proving the new moveable rudder system. One flight lasts for 26 seconds and several are more than 600 feet in length.

1902 29th December. Wilbur writes to Spratt about his plans for a glider with a 500 feet wing surface.

1902. In France, Ferdinand Ferber is experimenting with the Wright design after corresponding with Chanute who had then sent him details. Samuel Langley had also written to the brothers asking for details.

1903 With their mechanic Charles E. Taylor, they start work on their own 12 hp petrol engine to power the glider as they considered that no existing engine provided the power-to-weight ratio required.

1903 February First tests of the engine are a failure

1903 Langley gets finance for his new engine for his plane named the ‘Aerodrome’ from the US military

1903 The Wright’s new plane has a wing span of 40 feet 4 inches and a 6 feet 6 inch chord.

1903 They design and build their own propeller, considering nothing else suitable. This is 8 feet 6 inches in diameter and two are planned for the plane.

1903 They make their first application to patent the principle of control by wing warping but this is rejected as they have not used an attorney.

The plane was launched from a 60 feet track named the ‘Grand Junction’.

1904 The brothers were lent the use of Huffmann Prairie, farmland of 100 acres owned by Torrence Hoffmann close to Simms station on the Dayton, Springfield and Urbane railway.

1904 They design and build a new 4-cylinder engine and install two - one for each propeller - on the Flyer.

1904 March. Ferber experiments near Calais with a glider based on the Wright design.

1904 End May. The new flyer is completed and similar to the previous model but there are problems in flying it. They complete a derrick system with weights (800lb and later 1,400lb) to power launch the flyer.

1904 They decline to take part in the St Louis Fair and the competition for $100,000 for completion of a ten mile circular course around the fairground as they consider it optimised for airships and not planes.

1904 20th September. First completed circle flight witnessed by Amos I. Root

1908 9th September. Orville flies for 57.5 minutes and sets a new record and later that day flew again for more than 62 minutes. Later the same day he took Lahm as a passenger and flew for a record six minutes breaking the previous record set in May.

1908 mid September. Orville sets nine new world records including altitude of 200 feet and later 310 feet plus endurance of 74 minutes

1908 17th September having already flown previously with Frank Purdy Lahm and George Squier, Orville takes Selfridge as a passenger but crashes and Selfridge is killed and Orville is hospitalised for six weeks. The crash is caused by a split in the propeller not being repaired fully. Katharine helped negotiate a one year extension for the trials because of the accident.

1908 October. Herring makes claim that he has a working plane which he flew on 28th October but there were no witnesses and nothing more was heard or seen of it

1908 30th October. Henry Farman makes the first ever cross-country flight from Camp de Chalons to Reims in twenty minutes, a distance of 27 kms.

1909 22nd November. The Wright Company was incorporated and set up a factory at Dayton and a flying field at Huffmann Prairie

In mid-1910 they introduce the ‘B Flyer’ which does away with the canard, the horizontal flap mounted in front of the pilot and featured an aft horizontal tail. This plane was more stable in pitch and was much easier to fly.

1910 January. US Flying Show at Los Angeles. Louis Paulhan was only European and when he arrived in the country the Wrights issued him with a writ for patent infringements to stop him flying. They also issued an injunction against Curtiss but he ignored it and carried on flying. Paulhan also ignored his writ and climbed his plane to a record height of 4,165 feet.

1910 17th February. Paulhan is served with an injunction to stop his flying at a series of shows so he packs up and returns to France.

1910 March. The Wright brothers open a flying school at Montgomery, Alabama. The Wright pilots included Arch Hoxsey, Ralph Johnstone and Frank Coffyn. Walter Brookins was one of the trainers. Curtiss also formed a flying school and his pilots included Charles Willard, Charles Hamilton and Beckwith Havens.

1910 Belmont Meeting. Claude Grahame-White takes the prize for reaching 61 mph and John Moisant wins a prize for flying from Belmont Park and around the Statue of Liberty. The Wright Brothers were expected to win the Bennett prize for speed with their scaled down Model B with 21 feet wing span called the ‘Baby Grand’ and fitted with an eight-cylinder engine but engine failure caused them to pull out

1910 At the Overland Park meeting at Denver three Wright pilots took part but Ralph Johnstone reached 800 feet but on his descent the plane broke up and he was killed.

1911 John Moisant is killed when his Bleriot plane crashes near New Orleans.

1911 On the same day as John Moisant, Arch Hoxsey reached 7,000 feet in an attempt on the altitude record but as he glided back his plane flipped and he was killed.

1914 9th February. Harry Post established the altitude record of more than 12,000 feet in his Model C at San Diego, loses control on the descent and is killed in the crash. The army’s inquirey condemned the plane as the elevators were too weak.

1915 October. Orville sells the Wright Company but was retained as Consulting Engineer

1917 Bishop Wright dies

1917 The Dayton-Wright Airplane Company formed

1918 May. Orville flies for the last time. This is a demonstration flight of the 1911 model alongside a DH-4 plane.

1925 "The historic aeroplane with its small home-made four-cylinder petrol engine on which Wilbur and Orville Wright in the autumn of 1903 made their first power-driven flight at Kitty Hawk, South Carolina, is, it seems, now lying at Dayton, Ohio, packed in crates ready for shipment to the Science Museum at South Kensington. Mr. Orville Wright, it is reported, has expressed his regret at having to send the machine to a museum outside his own country. His decision to do so has been dictated by the action of the Smithsonian Institute at Washington, which in 1914 allowed the Langley " Aerodrome " entrusted to its care to be taken away, modernised and modified and otherwise made to fly with the object, so it said, of proving that Samuel Langley had anticipated the Wrights' invention and of providing evidence for a law suit attacking the validity of the original Wright patents. Mr Wright refuses to allow any museum discretion to make alterations in his machine, and adds that if half the changes permitted in the Langley aeroplane were allowed in the Kitty Hawk machine it could easily be proved that his aeroplane was not capable of sustained free flight. The Smithsonian Institute has defended its action in permitting the alterations to and experiments with the Langley machine on the ground that it was not a historical relic, but was received from the War Department for the purposes of experiment. There can, of course, be little doubt that no such treatment of a pioneer device of whatever nature and however received would be permitted by any museum authority in this country." [2]

1926 20 November. Katharine marries Henry J. Haskell, an associate editor of the Kansas City Star much to Orville’s displeasure

1929 3rd March. Katharine dies of pneumonia in Kansas City
