You do not have permission to edit this page, for the following reasons:
This IP address has been blocked from editing Wikipedia.
This does not affect your ability to read Wikipedia pages.
Most people who see this message have done nothing wrong. Some kinds of blocks restrict editing from specific service providers or telecom companies in response to recent abuse or vandalism, and can sometimes affect other users who are unrelated to that abuse. Review the information below for assistance if you do not believe that you have done anything wrong.

The IP address or range 34.205.0.0/16 has been blocked (disabled) by ‪ST47‬ for the following reason(s):

The IP address that you are currently using has been blocked because it is believed to be a web host provider. To prevent abuse, web hosts may be blocked from editing Wikipedia.
You will not be able to edit Wikipedia using a web host provider because it hides your IP address, much like a proxy or VPN.
We recommend that you attempt to use another connection to edit. For example, if you use a proxy or VPN to connect to the internet, turn it off when editing Wikipedia. If you edit using a mobile connection, try using a Wi-Fi connection, and vice versa. If you are using a corporate internet connection, switch to a different Wi-Fi network. If you have a Wikipedia account, please log in.
If you do not have any other way to edit Wikipedia, you will need to request an IP block exemption.

How to appeal if you are confident that your connection does not use a web host's IP address:
If you are confident that you are not using a web host, you may appeal this block by adding the following text on your talk page: ((unblock|reason=Caught by a web host block but this host or IP is not a web host. My IP address is _______. Place any further information here. ~~~~)). You must fill in the blank with your IP address for this block to be investigated. Your IP address can be determined here. Alternatively, if you wish to keep your IP address private you can use the unblock ticket request system. There are several reasons you might be editing using the IP address of a web host (such as if you are using VPN software or a business network); please use this method of appeal only if you think your IP address is in fact not a web host.

Administrators: The IP block exemption user right should only be applied to allow users to edit using web host in exceptional circumstances, and they should usually be directed to the functionaries team via email. If you intend to give the IPBE user right, a CheckUser needs to take a look at the account. This can be requested most easily at SPI Quick Checkuser Requests. Unblocking an IP or IP range with this template is highly discouraged without at least contacting the blocking administrator.

This block will expire on 05:44, 30 September 2026.

Even when blocked, you will usually still be able to edit your user talk page, as well as email administrators and other editors.

For information on how to proceed, please read the FAQ for blocked users and the guideline on block appeals. The guide to appealing blocks may also be helpful.

No. 1 was inflated again in the [[Bois de Boulogne|Aclimation Garden]] in Paris on 18 September 1898, but was damaged before it could fly, due to a misjudgement by the ground crew holding the ropes. Repaired two days later, the aircraft took off and flew. The air pump for the internal balloon, which kept the envelope rigid, did not work properly,<ref name=Studart2006 />((rp|p=15)) and the airship, at a height of 400 metres, began to flex and descend rapidly.<ref name=Barros2021 />((rp|p=3)) In an interview, Santos-Dumont told how he escaped death:

((Blockquote|The descent was at a speed of 4 to 5 m/sec. It would have been fatal if I hadn't had the presence of mind to tell the passersby, spontaneously suspended from the dangling cable like a real human cluster, to pull the cable in the opposite direction to the wind. Thanks to this manoeuvre, the speed of the fall decreased, thus avoiding the greater violence of the shock. I thus varied my amusement: I went up in a balloon and came down in a kite.<ref>Aimé, Emmanuel. ''L'Aérophile. '' Paris: Aéroclub de France, 9o ano, no 4, apr. 1901, p. 76.</ref>))

In 1899, Santos-Dumont built a new aircraft, No. 2, with the same length and similar shape, but a larger diameter of 3.8 metres, increasing the volume to 200 cubic metres.<ref name=Hoffman />((rp|p=387)) To address the unreliability of the air pump which had almost killed him, he added a small aluminium fan to maintain pressure and rigidity.((sfnm|1a1=Hoffman|1y=2010|1p=87|2a1=Barros|2y=2021|2p=3))

The first test was scheduled for 11 May 1899. At the time of the flight, rain made the balloon heavy. The demonstration consisted of simple manoeuvres with the aircraft attached by a rope, but ended in the adjacent trees.

The challenge became known as the Deutsch Prize. The regulations stipulated that an aircraft must be able to fly to the Eiffel Tower, round the monument, and return to the place of ascent in no more than thirty minutes, without stops, a total of 11 kilometres, under the eyes of a commission from the Aeroclub de France convened at least one day in advance. This required a minimum average speed of 22&nbsp;km/h.<ref name=Hoffman />((rp|p=94))

The award encouraged Alberto Santos-Dumont to try faster flights with No. 4.<ref name=Hoffman />((rp|p=178)) The aircraft was 420 cubic metres in volume, 29 metres long, and 5.6 metres in diameter.<ref name=Hoffman />((rp|p=388))((efn-ua|For an in-depth look at the characteristics of the No. 4, read ((harvnb|''CENDOC'', Rio de Janeiro|2021|p=24)))) Underneath was a 9.4-metre bamboo keel, in the middle of which were the saddle and pedals of an ordinary bicycle. Astride the saddle, the pilot had under his feet the starting pedals of a 7&nbsp;hp engine, which powered a front propeller with two 4-metre long silk blades. Next to the pilot were ropes with which he could control the carburettor and valve settings, the rudder, ballast, and displacement weights.<ref name=Hoffman />((rp|pp=95–97)) Santos-Dumont made almost daily flights in No. 4 from Saint Cloud during August. On 19 September, before members of the International Congress of Aeronauts, he proved the effectiveness of an aerial propeller driven by an oil engine by flying repeatedly against the wind, even with a broken rudder, impressing the scientists present.<ref name=Hoffman />((rp|pp=98–99)) The general impression was that he would win the Deutsch Prize, and upon going to Nice after falling ill, he began designing No. 5.<ref name=Barros2003 />((rp|p=314))

No. 10, a 2,010 cubic metre airship with a 60&nbsp;hp engine, was large enough to carry several people and serve as public transport. It made a few flights in October 1903, but was never completely finished; No. 11 was an unmanned monoplane.((efn-ua|Dumont reportedly abandoned the monoplane in favour of a biplane due to the Voisin brothers' persuasion.<ref name=Mattos2012 />((rp|p=366)))) No. 12 was a helicopter never completed due to the technological limitations of the time and finally, No. 13, a luxurious double hot air and hydrogen balloon.((sfnm|1a1=Hoffman|1y=2010|1p=390|2a1=Brandão|2y=2018|2p=6))

===Heavier-than-air flight===

[[File:First flights in aviation history.ogg|left|thumb|thumbtime=21|Footage of Santos-Dumont in the 21st second of a 1945 newsreel about the various human flight debuts, there are factual errors in the narration]]

In October 1904, three aviation prizes were founded in France: the ((ill|Archdeacon Prize|pt|Prêmio Archdeacon)), the ((ill|French Aeroclub Prize|pt|Prêmio do Aeroclube da França)), and the ((ill|Deutsch-Archdeacon Prize|pt|Prêmio Deutsch-Archdeacon)). The first, promoted by millionaire [[Ernest Archdeacon]], would award 3,500 francs to anyone who flew 25 metres; the second, instituted by the French aeroclub, would award 1,500 francs ($300) to anyone who flew 100 metres; and the third, sponsored by Henri Deutsch de la Meurthe and Ernest Archdeacon, would award 1,500 francs to anyone who flew 1,000 metres.<ref name=Hoffman />((rp|p=281))

With the exception of the Deutsch-Archdeacon Award, which prohibited the competing aircraft from using a balloon for launch, the other awards left the question of takeoff open. The flight could take place on flat or uneven terrain, in calm weather or wind – the French Aeroclub's Award required the flight to be into the wind – and the use of an engine was not mandatory. This allowed human-powered gliders and ornithopters to compete. It was required for all prizes that the race took place in France and under the supervision of an aeronautical commission convened no later than the evening of the previous day.<ref>''Les concours d'aviation''. ''L'Aérophile.'' Paris: Aéroclub de France, 12o ano, no 10, out. 1904, p. 224-225.</ref>

Very little of what was required was new. Inventors in other countries had already met or exceeded some of the required goals including 2-axis (pitch and roll) control of gliders.((efn-ua|Henrique Lins de Barros' article says that the FAI did not consider that the claims of earlier flights (Ader, Lilienthal, Whitehead and Wrights) satisfied its criteria and that until 1905 there had been "...no actual flight of a heavier-than-air aircraft...".<ref name=Barros2006a />((rp|pp=39–40)) The United States did not come up with its definitions until December 1907.<ref name=Mattos2012 />((rp|p=374)) For other definitions, see ((harvnb|Brandão|2018|p=2)).<ref name=Brandão2018 />((rp|p=2)) ((harvnb|Barros|Barros|2006)) raises the question of the definition of flight: if by flight one considers only movement through the air, then the Wrights take precedence. If the criteria of public test and unassisted takeoff are considered, then precedence lies with Santos-Dumont. They consider that the Demoiselle represented the "first modern airplane".<ref name=BarrosBarros2006 />((rp|p=27)))) In Germany, [[Otto Lilienthal]] had made thousands of glider flights in the early 1890s, often reaching distances far greater than the 25 metres stipulated by the Archdeacon Prize. In the United States, German immigrant [[Gustave Whitehead]] had allegedly pioneered powered glide, though claims and eye witness accounts remain controversial. The Wright brothers had simultaneously been making progress in developing surface-control gliders, at first using Lilienthal's foil concepts, then relying on their own wind tunnel data, and finally adding yaw control via a rudder, leading to the first 3-axis surface-controlled aeroplane in 1903. However, because their 12 horsepower engine could only provide two-thirds of the thrust required for takeoff on a rail of practical size, their takeoffs were aided by headwinds near Kitty Hawk and a catapult in Ohio, and without any official observers.<ref>((cite web | url=https://books.google.com/books?id=V3awCQAAQBAJ&q=%5B%5Birm%C3%A3os+Wright%5D%5D+faziam+desde+1903+voos+cada+vez+mais+longos+em+planadores+motorizados%2C&pg=PA159 | title=trecho do livro '''Imortais''' de ''Cláudia Barbosa''... desde 1903 voos cada vez mais longos em planadores motorizados |language=pt-br| last1=Barbosa | first1=Cláudia | date=28 May 2015 )) Site Google Books – accessado em 29 de fevereiro de 2016</ref><ref name=Palhares/><ref name=Mattos2012 />((rp|p=376)) Lilienthal's death due to a stall led the Wright brothers to place the elevator in front, which helped prevent stalls but made stable flight difficult until the Wrights modified the design; the 3-axis surface control (pitch, yaw and roll) pioneered by the Wrights was also adopted by other inventors including Santos-Dumont and remains the standard airplane control configuration.((sfnm|1a1=Barros|1y=2003|1p=320|2a1=Mattos|2y=2012|2p=356))((efn-ua|The canard configuration has been rediscovered in modern aircraft such as Gripen, Rafale, Eurofighter Typhoon and Sukhoi-35 because it is now possible to maintain rapid stability control.<ref name=Exacta2006 />((rp|p=231))))

====Glider and helicopter====
Having already accumulated technical knowledge, mainly concerning engines,<ref name=Brandão2018 />((rp|p=7)) in early 1905, Santos-Dumont built a model glider, No. 11, inspired by a self-stabilising prototype made 100 years earlier by English scientist [[George Cayley]], considered to be the first aeroplane in history: the model, 1.5 metres long by 1.2 metres wide, had fixed wings, a cruciform tail and a movable weight to adjust the centre of gravity. Santos-Dumont's glider differed from Cayley's in size, wing profile, and the fact that it had no movable weight.<ref>((Cite web|url=http://www.aer.ita.br/~bmattos/sd/aeronaves/11.html|title=Aeroplano Número 11|language=pt-br|access-date=2017-07-27|archive-url=https://web.archive.org/web/20140419025431/http://www.aer.ita.br/~bmattos/sd/aeronaves/11.html|archive-date=2014-04-19))</ref><ref>((Cite web|url=http://www.dmi.unipg.it/mamone/sci-dem/contri/danhoni.htm|title=History of Santos-Dumont's Inventions|work=[[University of Perugia]]|access-date=2019-12-08|archive-date=2021-09-13 |archive-url=https://web.archive.org/web/20210913003740/http://www.dmi.unipg.it/mamone/sci-dem/contri/danhoni.htm))</ref> The project was abandoned due to poor stability.<ref name=Brandão2018 />((rp|p=7)) An article by Georges Blanchet published in April 1904 diverges from the description of the No. 11 as a model aeroplane by presenting it as a dirigible balloon capable of carrying five people and a 34-metre-long envelope, being purchased by an American.<ref name=Blanchet1904 />((rp|p=91))

[[File:Helicóptero de Alberto Santos Dumont.jpg|thumb|No. 12 (helicopter) under construction]]

The first experiment, conducted on 13 May at the Aeroclub de France, was made by the Dufaux brothers with a prototype helicopter. The model, weighing 17 kilograms and with a 3&nbsp;hp engine, repeatedly soared to the roof of the air club's porch, raising clouds of dust. It had been demonstrated that heavier, larger aircraft could be lifted by their own means.<ref>''Mais pesado que o ar'', ''Jornal do Commercio''. Rio de Janeiro: Propriedade de Rodrigues & Comp., no 161, domingo, 11 jun. 105, p. 3.</ref> The second experiment was made on 8 June on the Seine: [[Gabriel Voisin]] went up in the hydroplane Archdeacon, towed by a speedboat piloted by ((ill|Alphonse Tellier|fr|Alphonse Tellier (constructeur aéronautique))), La Rapière. The device barely rose out of the water and the project was abandoned due to poor stability.<ref name=Hoffman />((rp|p=277)) Watching tests like this, Santos-Dumont realised that the Antoinette engine from the tugboat could be used in an aeroplane, giving the concept of the 14-bis.<ref name=Mattos2012 />((rp|p=366))((efn-ua|Gabriel Voisin's test indicated that an engine of at least 50 hp would be required for takeoff.<ref name=BarrosBarros2006 />((rp|p=24))))

He began to study the two solutions for heavier-than-air flight. On 3 January 1906, he entered the Deutsch-Archdeacon Prize, and before that he had begun building a helicopter, the No. 12, but gave up on it on 1 June because it was impossible to create a light, powerful engine.<ref name=Hoffman />((rp|p=277)) Between June 12 and August 25, 1905, he tested the No. 14 airship, which flew in two versions (14-a and 14-b): the first was 41 metres long, 3.4 in diameter and 186 cubic metres, with a 14&nbsp;hp engine, and the second was 20 metres long, 6 in diameter and with a 16&nbsp;hp engine.((sfn|Visoni|Canalle|2009|p=3|loc=5.

====''Oiseau de Proie I''====
Santos-Dumont decided not to compete for the prizes with the hybrid, but on 20 July signed up for the tests and over the next three days continued to test the plane tethered to the balloon, to practise steering. Throughout the tests he realised that, although the balloon helped take-off, it made flight difficult as the drag generated was too great.<ref name=Hoffman />((rp|pp=279–280)) The airship was discarded, and the biplane received the name ''Oiseau de Proie'' ("Bird of Prey") from the press.<ref name=Hoffman />((rp|pp=279–280)) The ''Oiseau de Proie'' had been inspired by the hydroplane tested by Voisin. Like the water glider, the invention also consisted of a cellular biplane based on the structure created in 1893 by Australian researcher [[Lawrence Hargrave]], which offered good support and rigidity.((sfnm|1a1=Hoffman|1y=2010|1p=275|2a1=Barros|2y=2021|2p=8)) The plane was 4 metres high, 10 metres long, and had a span of 12 metres,<ref name=Hoffman />((rp|p=391)) with a wing area of 50 square metres.

On 29 July, using a donkey and a system of cables, Santos-Dumont hoisted the ''Oiseau de Proie'' to the top of a tower<ref name=Hoffman />((rp|pp=279–280)) 13 metres high (2 metres were stuck in the ground), installed a few days earlier on his property in Neuilly. This frame was very similar to the one Ferber had used at Chalais-Meudon for the May 1905 experiments with the 6-bis. The plane, suspended on a movable hook connected to an inclined steel wire, glided without a propeller 60 metres from the top of the tower to a smaller one, only six metres long, on the Boulevard de la Seine. This allowed Santos-Dumont to get a feel for the aeroplane and to study its centre of gravity.<ref>DEGOUL, Marius. ''L'aeroplane Santos Dumont'', ''L'Aérophile''.

On 23 October, Santos-Dumont presented himself at Bagatelle with the ''Oiseau de Proie II'', a modification of the original model. The plane had been varnished to reduce the porosity of the fabric and increase lift. The rear wheel had been removed. In the morning he limited himself to manoeuvring the aircraft across the field, until the propeller shaft broke. It was repaired in the afternoon, and the plane was moved into position for an official attempt. An expectant crowd was present. At 4:45 pm, Santos-Dumont started the engine.((sfnm|1a1=Hoffman|1y=2010|1p=283|2a1=Barros|2y=2006a|2p=41)) The plane lifted off and flew for 60 metres,<ref name=Studart2006 />((rp|p=18)) without taking advantage of headwinds, ramps, catapults, slopes, or other devices.

The aeroplane was still experimental. To compete for the French Aeroclub's prize, Santos-Dumont inserted two octagonal surfaces (rudimentary [[aileron]]s) between the wings for better steering control and created the ''Oiseau de Proie III''.((sfnm|1a1=Hoffman|1y=2010|1p=290|2a1=Brandão|2y=2018|2p=8)) Santos-Dumont was a pioneer in implementing ailerons in his aircraft.<ref name=Mattos2012 />((rp|p=367))((efn-ua|In 1906 the Wright brothers were granted a patent for wing-warping, which provided control equivalent to ailerons, and they subsequently sued [[Glenn Curtiss]] and European aviators for patent infringement.<ref name=Mattos2012 />((rp|p=375)) In France, Henri Farman claimed to have created this technology.<ref name=Brandão2018 />((rp|p=8))))

To test the idea that the rudder at the rear increased the angle of incidence of the wings, Santos-Dumont built a new aircraft, without abandoning the 14-bis,<ref name=Barros2003 />((rp|p=324)) and tested it in March 1907, without taking off<ref name=Barros2003 />((rp|p=325)) as the primitive landing gear did not allow it.<ref name=Barros2006a />((rp|p=43))

He returned to the 14-bis having made other changes to the aircraft after 12 November, and on 4 April 1907, at Saint-Cyr, the aircraft flew for 50 metres, oscillated, crashed, and was torn to pieces.

In 1918 Santos-Dumont bought a small plot of land on the side of a hill in [[Petrópolis]] in the Serra Fluminense mountains, and built a small house there filled with mechanical devices, including an alcohol-heated shower of his own design. The hill was chosen because of its steep slope, as proof that ingenuity could make it possible to build a comfortable home in that unlikely location.

On 25 July 1909, [[Louis Blériot]] crossed the [[English Channel]], becoming a hero in France.

((Blockquote|This superb genius of athletic forms, with a grave profile, holding open in the tethers of his arms his wings, rudely wielded like two shields, nobly symbolizes the great work of Santos-Dumont: he would evoke in a very inaccurate way the simple, agile, laughing little big man that he is in reality. Dressed in a jacket and very short pants that are always rolled up, covered with a soft hat whose brim is on the other hand always folded back, there is nothing monumental about him. What distinguishes him is his taste for simplification, for geometric shapes, and everything in his appearance denotes this character. He has a passion for precision instruments. Small precision machines are installed on his work table, true jewels of mechanics, which are of no use to him and are only there for the pleasure of having them as knickknacks. There, next to a barometer and a microscope of the latest model, you can see a marine chronometer in its mahogany case. Even on the terrace of his villa stands a splendid telescope, with which he indulges in the fantasy of inspecting the sky. He has a horror of all complication, all ceremony, all pomp. So, what a rude and delicious ordeal for his modesty, this inauguration! I have known him for thirteen years; it was the first time I saw him in top hat and overcoat. And even for this single circumstance – supreme concession to custom – his properly stretched pants covered his astonished boots. Standing at the foot of his own monument, dressed as an official hero, transfixed with embarrassment and clumsiness, he seemed to me like a kind of martyr to glory.<ref>SEM, ''Santos Dumont, L'Illustration''.

===Sexuality===

Santos-Dumont never married and was rather shy, and his sexuality has long been debated, including by his biographers.<ref>((cite web|url=https://revistapesquisa.fapesp.br/?art=3080&bd=1&pg=7&lg|title=Revista FAPESP: 100 anos no ar|access-date=2019-07-25|language=pt-br|archive-url=https://web.archive.org/web/20171008233428/https://revistapesquisa.fapesp.br/?art=3080&bd=1&pg=7&lg|archive-date=2017-10-08))</ref>

===Mental health===
Santos Dumont is traditionally described as having developed [[multiple sclerosis]]. However, this diagnosis is disputed by other researchers:

[[Henrique Lins de Barros]] questions this diagnosis: "I think it difficult to believe in this hypothesis of multiple sclerosis... How could anyone suffering from a degenerative disease like multiple sclerosis ski in Saint Moritz in the 1910s and play tennis in the 1920s, as he did?" Marcos Villares Filho, great-grandnephew of Santos-Dumont, says that he probably had a profound depression.<ref name=OHY/> The documentation of the time does not provide a good deal of information to determine that Santos Dumont suffered from multiple sclerosis.<ref name=MaiaBarros>((Cite journal|title= Did the "Father of Aviation" have his wings clipped by depression? |last=Maia Barros|first=Régis Eric|journal=Rev.

The original diagnosis came after consulting a doctor due to symptoms such as dizziness and double vision. Later, this diagnosis was challenged by other doctors, who believed that the aviator was already suffering from psychiatric manifestations.((sfn|Cheniaux|2022|p=65|loc=Depression and suicide)) The symptoms reported for the original diagnosis would be only two related to multiple sclerosis.<ref name=Cheniaux2022>((Cite journal|title= The bipolarity of Alberto Santos-Dumont: flights and falls of the "Father of Aviation"  |last=Cheniaux|first=Elie|journal=J.

((harvnb|Cheniaux|2022)) reports several episodes showing bursts of energy when at times outside his depressive episodes.((sfn|Cheniaux|2022|p=66|loc=Other possible psychiatric manifestations)) Santos Dumont reportedly developed depression in 1910, predating the use of the aeroplane in the war, which, according to the cited article, would indicate that his feeling of guilt was a symptom rather than the cause.<ref name=Cheniaux2022 />((rp|p=67)) Cheniaux hypothesizes that Santos Dumont suffered from bipolar disorder or manic syndrome, with his latest bizarre inventions being able to demonstrate the "loss of critical ability".<ref name=Cheniaux2022 />((rp|p=67)) A letter written in 1931 by a doctor at the Orthez sanatorium to a friend of Santos Dumont describes him as 'suffering from anxious melancholy with delusions of self-blame, from imaginary guilt, and awaiting punishment', also identified as [[neurasthenia]], an exhaustion of the central nervous system.<ref name=Oliveira2022 />((rp|p=271))

Bipolar disorder is one of the disorders most connected with suicide and Santos Dumont already had precedents in his family, with his mother having taken her own life<ref name=Cheniaux2022 />((rp|p=67)) in 1902<ref name=Cheniaux2022 />((rp|p=66)) and that the aviator already demonstrated at the end of his life a number of epidemiological risk factors for suicide.<ref name=MaiaBarros />((rp|p=208)) It is hard to determine any diagnosis due to the lack of medical documentation.((sfn|Cheniaux|2022|p=66|loc=Discussion))
