The plane Demoiselle
The Demoiselle monoplane small, fragile, seemingly unable to support a single pilot, reflects not only human also shorter than designed, but the long line of boats are lighter than air that had preceded it. The designer, five feet four inches, £ 110 Alberto Santos-Dumont, who came from Brazil, had spent most of his life in France, instead of the first successful ascent by balloon Montgolfier brothers in 1783 and an event that may have unintentionally caused its own related experiences.
Unlike aircraft fixed wing or rotary wing, using the science of aerodynamic lift, these balloons are the principle of buoyancy.
Air is compressible, it is by its own weight compresses. Plus your location in the atmosphere, the more air and therefore the weight is over, making it more dense or near the ground. On the contrary, As it rises, it becomes thinner.
hot air balloons use the following conditions to reach an elevator. Air hot or a gas lighter than air inside a balloon envelope goes the balloon to rise, because indoor air is less dense than the surrounding air. When you reach the altitude where the air density inside is equal to the ambient air is increasing and reaches a steady state internal and external, or inside the gas density is equal to the external gas density.
At this stage, the downward pressure exerted on the ball is equal to the upward pressure on the globe.
The balloons are called "balls" because their elevation is reached in a static air mass, ie a mass of air that moves. A ball is moved vertically but is based on the current wind direction and speed of horizontal movement. Therefore, can not be invoked to address specific transport.
Balloons with the movement controlled using one or more speed and direction, and designated "aircraft", but these blades do not provide or increase lift.
Santos-Dumont had, even at an early age, decided to have a profound impact on people in his life, but did not yet determined the media. However, a fascination with flying, in general, and balloons, in particular, only continued to increase, forcing concentrating on gaps in their direction and leads you to believe that your address without aim, since the wind could be replaced by steering.
Only after his balloon ascent clean air first 40 meters in diameter in the fall of 1897 which concluded that the aircraft launched an appeal for his life.
Trying to control the uncontrollable factor, he designed an aircraft designated "Santos-Dumont No. 1." With balloon overall cigar-shaped elongated than 6454 cubic feet of gas had a capacity of 450 pounds, was powered by a combustion engine led to an internal diameter of the helix by 6.6 meters, to provide the feed rate, while the direction of increased rudder and two heavy bags suspended from the ballast tank, therefore, placed at the rear, replaced by the later, heavier than air craft lifts production control stage. The pilot was in a basket and cable protection ground crew to maneuver the airship and has from its mooring position.
First flight 18 September 1898 in Paris, gently struck trees across the field that was abandoned because of the distance in which good rising above them, but after the repair of two days, was a success, showing Santos-Dumont expected, the rudder is always in control.
Follow circles and eight in the sky, the No. 1 incorporates all the elements needed to succeed on the gravity of the ball and lift motor propeller movement forward, the rudder, and bags of ballast to the task.
The success, Santos-Dumont No. 2 focused more than one world, including more than ten percent of the volume of gas led to a greater ability to lift 44 pounds.
With the end of the house No. 3 successor, which reached a record longevity of the air 23 hours straight, Santos-Dumont built a hangar with doors 36 feet high at Saint-Cloud near Paris.
The October 19, 1901, won the prize of 100,000 French francs offered by Henry Deutsch de la Meurthe, a founding member of the Aero Club Paris, Eiffel Tower and circling back to the box 30 minutes later in the No. 6 design, an airship 108 feet long with a set of rear propeller.
Despite these successes, however, soon became heavier than air flight. To fulfill the promise of Samuel Pierpont Langley, the curator of the Museum Smithsonian, which had launched its own success "Aerodrome Design a catapult on the Potomac River, to begin experimenting with this field lifting, and trying to regain its reputation after suspected sabotage had led to cuts on his No. 7 ball and prevented from entering in the St. Louis Aero Club competition for a price of $ 100,000, has designed a monoplane glider equipped pontoon power in Paris. Designated No. 11 boat was quickly removed, making it the go over the water, while the No. 12 after a double helix, helicopters, not in the air because the technology of vertical flight has been sufficiently developed at the turn of the century.
No. 14-bis, but – Despite offering a small contribution to the advancement aerodynamic – achieved notoriety in both the continental and technological success due to lack of pure competition. Jointly designed by Santos-Dumont, Voisin, an engineer of 25 years, who had set their sights on heavier-than-air art and shared their knowledge about Santos-Dumont in the winter of 1905-1906 was a plane 40 meters long with 33 feet of wing cell lines Kite box attached by piano and dihedral bracing pine and extreme, a fuselage length, indoor, a unique cell phone, providing box length of handset and tone, control of duck and 24 horses, less wing attached plan Antoinette engine, driving a crude, scapula, pusher-propeller. This was reinforced later with a 50 horsepower engine and an octagonal wings. Control can be provided by a pilot. Because was the first test flight of the aircraft suspended No. 14, which had adopted the "14 bis" designation, but had its own duck won the title of "Bird of Prey" by the press.
Won Prize Archdeacon October 23, 1906 for a flight of 25 meters and the French franc in 1500 Aero Club Award coverage for 100 yards on 12 November, the latter being considered Europe recognizes for the first time, sustained, heavier than air and triumph for a time, believes the world was due to the Wright brothers' own experiences in the secret undocumented.
After heavier than four intermediate air developments, but without success, Santos-Dumont has been applied as your signature design philosophy related to its next plane fixed wing development, ie use the smallest possible cell, which could accommodate him to produce a sport plane, similar a custom car antenna.
The resulting design, No. 19, was a small tractor monoplane whose "body" had made of bamboo and the wings are covered with fabric, spanning 16.5 meters, retained pronounced dihedral presented by No. 14-bis. A two-cylinder, 20 horsepower Dutheil-Chalmers engine is mounted on the driver in a mid-wing of the coupling, provided power, while that combined rudder and the elevator was extended from two sides of the rudder under the lift and the wing before duck that stretched ahead structure. Aircraft wing deformation mechanism and the wings are missing, intrinsically incapable of being controlled around its lateral axis, made three short trips to the end of 1907, the longest was 200 meters before being damaged or removed from further testing. However, he laid the groundwork for the final aircraft, No. 20, which also gave Santos-Dumont past.
Maintaining the simplicity of minimalist design and size # 19, but eliminating its weaknesses, the aircraft made a three-arm, bamboo frame, the first extends from the wing to the tail, the latter extending below the wing to the axle of the wheel, and the third extends from that point to the tail, all subjects with steel joints.
The rectangular, substantially convex, high-wing, spaced 18 feet, a width of 6.35 meters, or a ratio of 2.7:1, and a 113-square meter area is covered with a double layer of silk stretched over the ribs Assembled bamboo as a feature of its fuselage in a pronounced dihedral angle. A cut along the edge, which represents one third of the length, to facilitate the installation of the propeller and the rotation, but at a low level and the area along this stretch.
and a vertical surface horizontal fan-shaped into a universal joint at the intersection in the top triangle, used to queue and yaw, respectively provided longitudinal motion control, the rudder itself an area of 21 square meters.
Power 30, two opposed cylinders horizontally, water-cooled Darracq motor, mounted, like No. 19, above the driver, has a diameter of 6.9 meters, height of six feet, two blades Chauvière wood propeller at 1400 rpm. Both cylinder valves were operated by rockers and push actively for two eccentrics. Your magnet was mounted at an angle in the engine top cover, while the fuel tank and oil were suspended below a reservoir-pump immersed in the lubrication fluid distribution.
The aircraft was powered by alternative Clément-Bayard and Panhard engines.
rolling is secured by two tires and single charger, small rear.
The pilot, rocked by a strip of cloth hanging in the box below the plant was like the Curtiss Model D, a virtual extension of the cell and the headquarters is limited to small farmers, £ 120. control longitudinal was maintained by a law, order lifting Palo Alto that was a switch engine for a short period of time to cause the court to decline. vertical control has been increased by the left, deviation of the wheel, while the lateral control was restored by a lever behind the driver and inserted into a pocket sewn narrow vertical on the back of a jacket in particular, effective delivery of the connection point between the body of a "Third hand". His son, active, like many pioneers of aircraft designs, the mechanism of the wing strain torso bent, changed incidence angle of making the bank the air. A footrest in the driver's left foot cable has a spring trigger for change the propeller revolutions per minute.
First introduced in France in March 1909, one year, similar to race, but more Bleriot XI plan elegant, small, with a 330 – the gross weight of 370 pounds, looked like a dragonfly or a girl because of her translucent wings of silk covered and was therefore nicknamed the "Demoiselle" in French. It was the first sport aircraft in the world.
Sharing the end of the pendulum dihedral wing and low, corresponding to the center of gravity with his No. 14-bis and 19 N º predecessors could benefit from design features such as static still air. These, however, do not exist, the aircraft therefore subject to fluctuations increasing destabilization resulting in excess, pitching and flight roll. However, as the first light aircraft piloted successfully married Santos-Dumont lighter than air with an internal combustion engine a minimum of eight fixed-wing structure. With an average speed exceeding flight level of 52 miles per hour, it was 12 pounds per horsepower and 3.1 pounds per square foot lift of the wing, even if time had reached a maximum speed of 55.8 km per hour in September 1909 flew a distance of 11 miles in 16 minutes.
Emulating the success of competing Blériot XI became the first Demoiselle Santos-Dumont, and only aircraft than doubled, and in large numbers. Clement-Bayard For example, an automobile manufacturer in Paris, built around 300 with the car engines of 30 horses and sold them $ 1,250 each, while the aircraft could be purchased for $ 1,000 in Chicago and $ 250 without engine Hamilton Aero Manufacturing Company. In France, a young lady driving school was established and sometimes boasted of Santos-Dumont as one of their instructors, and in 1911, Popular Mechanics magazine published drawings and assembly instructions. In addition, Bleriot XI as his time, he met privately in large quantities.
During a January 4, 1910 flight, the girl crashed according to one version, due to a broken wire reinforcement. "Although Santos-Dumont had threatened injury life, their emotional state was affected most precarious. Consequently, the girl became her latest design and flight on January 4, was his driver passed, the pioneer of 36 years, saying he had achieved the objectives of its unhappiness with her life.
Always intended to develop and advance aviation for the transport and development social and economic, which had been emotionally shattered by the destructive role he played during the First World War and had opposed vehemently. Haunted by the large number of lives lost prematurely as a result of his own invention, which ultimately ended his life 22 years later July 23, 1932, in Brazil, after reaching the goal, paradoxically, expressed his life that profoundly affect their inventions mankind in ways both positive and negative.
The Maid of the old library Rhinebeck Aerodrome is a reproduction that has been built by Cole Palen in the 1950s in his house with his parents Red Oaks Mills, the idea came from the same era and even built Curtiss Model D
In the example of Rhinebeck last restoration took place in the mid-1990s, when Dan Taylor, an early aircraft pilots Rhinebeck, had tried to make it more representative of the Demoiselle No. 20 and was assured that the original 30-horsepower two-cylinder air-cooled Aero Engine Detroit 1909, the guy who fed the cells had American-made. Savastino Paul, a mechanic and welder, he designed a plan that fits for mounting the engine can handle without overloading the building with bamboo.
Suspended from the high ceiling of New York Jacob Javits Center during the July 2002 to New York jewelry, timepieces Show, the monoplane represented both the Old Rhinebeck and Alberto Santos Dumont, Louis Cartier had forged nearly 100 years earlier when he designed a watch for him hands-free after learning that the pilot had been unable to control airship his plane while monitoring the time hunter with his pocket watch during his circumnavigation of the famous Eiffel Tower in search of price Deutsch.
Today the aircraft is represented in the old aircraft hangar Pioneer Rhinebeck Aerodrome, one of four buildings on the track on a hill.
