The centenary of the first 14-Bis flight

The conquest of the skies

On October 23^rd 1906, a crowd in Paris witnessed the first flight of a heavier-than-air aircraft. The pilot was Brazilian Santos Dumont, who had built the plane he called 14-Bis

   The world experienced one of the most creative periods in its history in the last decades of the 19th Century and the beginning of the 20th Century. It was in this period than man invented electric light, cinema and the automobile, amongst other inventions (read more about them on page 12). At that time man had flown in hot-air balloons, but no one had managed to fly in a motorized machine that was heavier than air and that could be controlled – that is, that could be directed wherever the pilot wanted it to go. Brazilian Santos Dumont was the first man to achieve this feat.  On October 23rd 1906, a crowd gathered in Paris and saw an aircraft fly for the first time without the aid of a catapult or any other external boost. Santos Dumont was piloting 14-Bis, as had called the plane he had made himself. This made the headlines the world over and the Brazilian became a worldwide celebrity.

A brief biography

Dumont: love for machines and aviation

He had a few accidents during test flights, but never gave up fighting for his dreams

   Alberto Santos Dumont was born on July 20, 1873 in a small city in Minas Gerais called Palmira (it is today called Santos Dumont, in honor of its illustrious son). When still a child, little Alberto used to like watching birds fly and asked how they could do it if they were heavier than air.  Dumont left Brazil when he was just 19 years old and went to live in France. In Paris he studied physics, mechanics and electricity. From 1898 he began planning, building and flying different hot-air balloons and dirigibles. Dumont had a few accidents during test flights, but he never gave up on his dreams. Besides becoming a famous aviator all over the world, Dumont was also well-known for other inventions of his, such as the wristwatch, for example. The Brazilian was considered to be a simple and generous man. In the last years of his life, Dumont suffered from two serious diseases: multiple sclerosis, and depression. On July 23rd 1932 Santos Dumont committed suicide in Guarujá (SP) andBrazil lost one of the greatest geniuses it has ever had. 

The aeronautical industry in Brazil

The Aeronautical Technology Center (CTA) was opened in the 1950s, in São José dos Campos-SP. It was the first step towards Brazil’s building of top quality airplanes and its advances in varied scientific and technological fields. Specialized schools were set up in CTA to train professionals to work in the aerospace industry and to fly planes. The following decade the government decided to build a large aeronautical company. Embraer (the Brazilian Aeronautical Company) was opened in 1969, also in São José dos Campos, being privatized in 1994. Today this company sells its airplanes to countries all over the world.

Caricature of Santos-Dumont from Vanity Fair, 1899

Alberto Santos-Dumont (July 20, 1873 – July 23, 1932) was a Brazilian early pioneer of aviation. Heir of a prosperous coffee producer family, Santos Dumont dedicated himself to science studies in Paris, France, where he spent most of his adult life.

Santos-Dumont designed, built and flew the first practical dirigible balloons. In doing so he became the first person to demonstrate that routine, controlled flight was possible. This "conquest of the air", in particular winning the Deutsch de la Meurthe prize on October 19, 1901 on a flight that rounded the Eiffel Tower,^[1] made him one of the most famous people in the world during the early 20th century.

In addition to his pioneering work in airships, Santos-Dumont made the first European public flight of an airplane on October 23, 1906. Designated 14-bis or Oiseau de proie (French for "bird of prey"), the flying machine was the first fixed-wing aircraft witnessed by the European press and French aviation authorities to take off and successfully fly. Santos-Dumont is considered the "Father of Aviation" in Brazil, his native country.^[2] His flight is the first to have been certified by the Aéro Club de France and the Fédération Aéronautique Internationale (FAI).^[3][4]

Santos-Dumont also occupied the 38th chair of the Brazilian Academy of Letters, from 1931 until his death in 1932.

Santos-Dumont was born in Cabangu Farm, a farm in the Brazilian town of Palmira, today named Santos Dumont in the state of Minas Gerais. He grew up as the sixth of eight children on a coffee plantation owned by his family in the state of São Paulo. His French-born father was an engineer, and made extensive use of the latest labor-saving inventions on his vast property. So successful were these innovations that Santos-Dumont's father gathered a large fortune and became known as the "Coffee King of Brazil."

Childhood

He was fascinated by machinery, and while still a young child he learned to drive the steam tractors and locomotive used on his family's plantation. He was also a fan of Jules Verne and had read all his books before his tenth birthday. He wrote in his autobiography that the dream of flying came to him while contemplating the magnificent skies of Brazil in the long, sunny afternoons at the plantation.

According to the custom of wealthy families of the time, after receiving basic instruction at home with private instructors including his parents, young Alberto was sent out alone to larger cities to do his secondary studies. He studied for a while in "Colégio Culto à Ciência", inCampinas.^{[citation needed]}

Move to France

In 1891, Alberto's father had an accident while inspecting some machinery. He fell from his horse and became a paraplegic. He decided to sell the plantation and move to Europe with his wife and younger children. At 17, Santos-Dumont left the prestigious Escola de Minas in Ouro Preto, Minas Gerais, for Paris in France. Shortly after he arrived, he bought an automobile. Later, he pursued studies in physics, chemistry,mechanics, and electricity with the help of a private tutor.

Balloons and dirigibles

Santos-Dumont described himself as the first "sportsman of the air." He started flying by hiring an experienced balloon pilot and took his first balloon rides as a passenger. He quickly moved on to piloting balloons himself, and shortly thereafter to designing his own balloons. In 1898, Santos-Dumont flew his first balloon design, the Brésil.

After numerous balloon flights, he turned to the design of steerable balloons or dirigible type balloons that could be propelled through the air rather than drifting along with the breeze (See Airship).

Between 1898 and 1905, he built and flew 11 dirigibles. With air traffic control restrictions still decades in the future, he would glide along Paris boulevards at rooftop level in one of his airships, commonly landing in front of a fashionable outdoor cafe for lunch. On one occasion he even flew an airship early one morning to his own apartment at No. 9, Rue Washington, just off Avenue des Champs-Élysées, not far from the Arc de Triomphe.

To win the Deutsch de la Meurthe prize Santos-Dumont decided to build a bigger balloon, the dirigible Number 5. On August 8, 1901 during one of his attempts, his dirigible lost hydrogen gas. It started to descend and was unable to clear the roof of the Trocadero Hotel. A large explosion was then heard. Santos-Dumont survived the explosion and was left hanging in a basket from the side of the hotel. With the help of the crowd he climbed to the roof without injury.

The zenith of his lighter-than-air career came when he won the Deutsch de la Meurthe prize. The challenge called for flying from the Parc Saint Cloudto the Eiffel Tower and back in less than thirty minutes. The winner of the prize needed to maintain an average ground speed of at least 22 km/h (14 mph) to cover the round trip distance of 11 km (6.8 miles) in the allotted time.

On October 19, 1901, after several attempts, Santos-Dumont succeeded in using his dirigible Number 6. Immediately after the flight, a controversy broke out around a last minute rule change regarding the precise timing of the flight. There was much public outcry and comment in the press. Finally, after several days of vacillating by the committee of officials, Santos-Dumont was awarded the prize as well as the prize money of 125,000 francs. In a charitable gesture, he donated 75,000 francs of the prize money to the poor of Paris. The balance was given to his workmen as a bonus. An additional matching 125,000 francs was voted to him along with a gold medal by the government of his native Brazil.

Santos-Dumont's aviation feats made him a celebrity in Europe and throughout the world. He won several more prizes and became a friend to millionaires, aviation pioneers, and royalty. In 1903 Aida D'Acosta Breckinridge piloted Santos-Dumont's airship. In 1904, he went to the United States and was invited to the White House to meet U.S. President Theodore Roosevelt.

In 1904, Santos-Dumont shipped his new airship No. 7 (also called Racer), to St. Louis from Paris in several crates to fly at the Louisiana Purchase Exposition. It was a new airship, built to compete for the Grand Prize of $100,000, which was to be given to a flying machine (of any sort) that could make three round-trip flights over a 15-mile “L”-shaped course at an overall average speed of 20 miles/hour (later reduced to 15 miles/hour). It was also necessary for the machine to land without damage (to craft or crew) not more than fifty yards from the starting point. Because he was probably the best-known aviator at the time, the Fair committee went to great lengths to ensure his participation, including modifying the rules. However, upon arrival in St. Louis, Santos-Dumont found his airship’s gas bag to be irreparably damaged; sabotage, although suspected, was never proven, and Santos-Dumont did not participate in the contest. In fact, suspicion of the deed, a repeat of a similar incident in Boston, began to focus somewhat absurdly on Santos- Dumont himself, and he indignantly left the Fair and returned immediately to France.

The public eagerly followed his daring exploits. Parisians affectionately dubbed him le petit Santos. The fashionable folk of the day mimicked various aspects of his style of dress from his high collared shirts to singed Panama hat.^{[citation needed]} He was, and remains to this day, a prominent folk hero in his native Brazil.

Heavier than air aircraft

The November 12 flight.

Although Santos-Dumont continued to work on dirigibles, his primary interest soon turned to heavier-than-air aircraft. By 1905 he had finished his first airplane design, and also a helicopter. He finally achieved his dream of flying an aircraft on October 23, 1906 by piloting the 14-bisbefore a large crowd of witnesses for a distance of 60 metres (197 ft) at a height of two to three metres (10 ft). This well-documented event was the first flight verified by the Aéro-Club de France of a powered heavier-than-air machine in Europe and won the Deutsch-Archdeacon Price for the first officially observed flight further than 25 meters. On November 12, 1906, Santos-Dumont set the first world record recognized by the Federation Aeronautique Internationale by flying 220 metres in 21.5 seconds.^[5][6]

Santos-Dumont made other contributions to the field of aircraft design. He added movable surfaces, the precursor to ailerons, between the wings in an effort to gain more lateral stability than was offered by the 14-bis wing dihedral. He also pushed for and exploited substantial improvements in engine power-to-weight ratio, and other refinements in aircraft construction techniques.

Alberto Santos-Dumont flying the Demoiselle over Paris

Santos-Dumont's final design was the Demoiselle monoplane (Nos. 19 to 22). This aircraft was employed as Dumont's personal transportation and he willingly let others make use of his design. The fuselage consisted of a specially reinforced bamboo boom, and the pilot sat on a tensionally-held seat between the main wheels of atricycle landing gear. The Demoiselle was controlled in flight partly by a tail unit that functioned both as elevator and rudder, and by wing warping (No. 20).

In 1908 Santos-Dumont started working with Adolphe Clément's Clement-Bayard company to build the Demoiselle No 19. They planned a production run of 100 units, built 50 and sold only 15 for 7,500 francs for each airframe. It was the world's first series production aircraft. By 1909 it was offered with a choice of 3 engines, Clement 20 hp; Wright 4-cyl 30 hp (Clement-Bayard had the license to manufacture Wright engines); and Clement-Bayard 40 hp designed by Pierre Clerget. The Demoiselle achieved 120 km/h.^[7]

The Demoiselle airplane could be constructed in only 15 days. Possessing outstanding performance, easily covering 200 m of ground during the initial flights and flying at speeds of more than 100 km/h, the Demoiselle was the last aircraft built by Santos-Dumont. The June 1910 edition of the Popular Mechanics magazine published drawings of the Demoiselle and affirmed that "This machine is better than any other which has ever been built, for those who wish to reach results with the least possible expense and with a minimum of experimenting." American companies sold drawings and parts of Demoiselle for several years thereafter. Santos-Dumont was so enthusiastic about aviation that he released the drawings of Demoiselle for free, thinking that aviation would be the mainstream of a new prosperous era for mankind.
