SANTOS DUMONT’S 14 BIS
More than a hundred Years Ago
|On 17 December 1903, the Wright brothers, in the USA, made use of a rudimentary catapult (with an inclined plane) to throw their Flyer biplane into the air, Santos-Dumont, however, would be the first to build and fly an aircraft "heavier-than-the-air" by its own means of propulsion,in october 23th 1906|
Alberto Santos-Dumont, 1873-1932
all the oppinions - specialy from brazilian people - Santos
Dumont wasn't the first man fo fly in a heavier than air machine.
The first registered flight was made by the Wright Brothers whoose
Flyer was cabable of take off, fly under control making curves ups
and downs and landing safely. The catapult was used to shorten the
take off, just as carrier ships do until today. They made their
first fly in 1903, three years before Santo Dumont. That's history.
No doubt about it.
flight of Santos-Dumont on the 14-bis at Bagatelle:
On November 12th 1906, Santos-Dumont improved even more the performance of his 14-bis and his flying ability, making several flights always increasing the distance flown, finally flying for 21.5 seconds at about 20 feet above ground, covering 700 feet at a speed of 25 mph
box kite tail unit was connected to the fuselage in such a way that
it could be moved up and down to act as an elevator and from side
to side to act as a rudder. The engine was a 50 hp Antoinette which
drove a metal pusher propeller 6 feet in diameter. The main landing
gear consisted of two wheels with rubber shock absorbers. A skid
supported the front part of the aircraft. The pilot stood in a wicker
basket just ahead of the engine; there was a control wheel linked
by cables to the forward surfaces, and for latter trials there were
ailerons mounted in the outer wing bays. Because the pilot's hands
were fully engaged with the other controls, the ailerons were linked
to a metal T-piece attached to a special coat and the airplane's
lateral control had to be attained by body movement.
|The fuselage of the Demoiselle No. 20 was still made of bamboo, but strengthened, the wing area was the same, but it was powered by a 35-hp engine. During tests in September 1909 it succeeded in flying for 16 minutes, covering about 11 miles. The much modified No. 19 was exhibited during that same month at the Grand Palace in Paris and was received with considerable enthusiasm. Santos-Dumont allowed anyone to copy his aircraft and it is believed that between ten and fifteen Demoiselles were built.|
