Bell Oionus I
The Oionus I was a tetrahedral triplane built for Alexander Graham Bell It was the culmination of Bell's experiments with kites built at Baddeck, Nova Scotia. The aircraft's design combined those of the Aerial Experiment Association (AEA)'s AEA Silver Dart biplane and his AEA Cygnet kite. It was Bell's final aviation pursuit and Canada's first and only triplane design. The aircraft attempted a test flight in March 1910, but failed to achieve flight. Design and development The Oionus I had its origins in March 1909 with the dissolution of the AEA, when Alexander Graham Bell hired both Frederick W. "Casey" Baldwin as an engineer and J.A.D. McCurdy as assistant engineer to build the last of Bell's designs.Molson and Taylor 1982, p. 103. Incorporating tetrahedral sections in the structure of the triplane design continued the concept of the tetrahedral kites that had originally been tested in Bell's AEA Cygnet series that had achieved a short hop in the Cygnet III but were ab ...

Baddeck, Nova Scotia
Baddeck () is a village in northeastern Nova Scotia, Canada. It is situated in the centre of Cape Breton, approximately 6 km east of where the Baddeck River empties into Bras d'Or Lake. Local governance is provided by the rural municipality of Victoria County, with an elected village council having limited authority. The population was 826 in the 2016 Canadian census. It was first settled by United Empire Loyalists in the late 18th century, and prospered in the 19th century with mining, milling, and shipbuilding. Today the economy depends on services, cultural activities, and tourism. Toponymy Baddeck is one of the few Nova Scotian Mi'kmaq language place names that was not replaced by colonial settlers. The French called it La Bedeque, while Canadian Gaelic speakers called it Badaig. Its original meaning has been variously reported as "reversing flow", "place with island near" (a likely reference to Kidston Island), "a portion of food set aside for someone", or "a sultry ...

Alexander Graham Bell
Alexander Graham Bell (, born Alexander Bell; March 3, 1847 – August 2, 1922) was a Scottish-born inventor, scientist and engineer who is credited with patenting the first practical telephone. He also co-founded the American Telephone and Telegraph Company (AT&T) in 1885. Bell's father, grandfather, and brother had all been associated with work on elocution and speech, and both his mother and wife were deaf; profoundly influencing Bell's life's work. His research on hearing and speech further led him to experiment with hearing devices which eventually culminated in Bell being awarded the first U.S. patent for the telephone, on March 7, 1876. Bell considered his invention an intrusion on his real work as a scientist and refused to have a telephone in his study. Many other inventions marked Bell's later life, including groundbreaking work in optical telecommunications, hydrofoils, and aeronautics. Bell also had a strong influence on the National Geographic Society and its ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tetrahedral
In geometry, a tetrahedron (plural: tetrahedra or tetrahedrons), also known as a triangular pyramid, is a polyhedron composed of four triangular faces, six straight edges, and four vertex corners. The tetrahedron is the simplest of all the ordinary convex polyhedra and the only one that has fewer than 5 faces. The tetrahedron is the three-dimensional case of the more general concept of a Euclidean simplex, and may thus also be called a 3-simplex. The tetrahedron is one kind of pyramid, which is a polyhedron with a flat polygon base and triangular faces connecting the base to a common point. In the case of a tetrahedron the base is a triangle (any of the four faces can be considered the base), so a tetrahedron is also known as a "triangular pyramid". Like all convex polyhedra, a tetrahedron can be folded from a single sheet of paper. It has two such nets. For any tetrahedron there exists a sphere (called the circumsphere) on which all four vertices lie, and another sphere ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Triplane
A triplane is a fixed-wing aircraft equipped with three vertically stacked wing planes. Tailplanes and canard foreplanes are not normally included in this count, although they occasionally are. Design principles The triplane arrangement may be compared with the biplane in a number of ways. A triplane arrangement has a narrower wing chord than a biplane of similar span and area. This gives each wing-plane a slender appearance with higher aspect ratio, making it more efficient and giving increased lift. This potentially offers a faster rate of climb and tighter turning radius, both of which are important in a fighter. The Sopwith Triplane was a successful example, having the same wing span as the equivalent biplane, the Sopwith Pup. Alternatively, a triplane has reduced span compared to a biplane of given wing area and aspect ratio, leading to a more compact and lightweight structure. This potentially offers better maneuverability for a fighter, and higher load-capacity wit ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Aerial Experiment Association
The Aerial Experiment Association (AEA) was a Canadian-American aeronautical research group formed on 30 September 1907, under the leadership of Dr. Alexander Graham Bell. The AEA produced several different aircraft in quick succession, with each member acting as principal designer for at least one. The group introduced key technical innovations, notably wingtip ailerons and the tricycle landing gear. According to Bell, the AEA was a "co-operative scientific association, not for gain but for the love of the art and doing what we can to help one another."Milberry 1979, p. 13. Although the association had no significant commercial impact, one of its members, Glenn Curtiss, later established a commercial venture that would ultimately become the Curtiss Aeroplane and Motor Company. The AEA was disbanded on 31 March 1909. Origins The AEA came into being when John Alexander Douglas McCurdy and his friend Frederick W. "Casey" Baldwin, two recent engineering graduates of the Universi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
AEA Silver Dart
The ''Silver Dart'' (or ''Aerodrome #4'') was a derivative of an early aircraft built by a Canadian/U.S. team, which after many successful flights in Hammondsport, New York, earlier in 1908, was dismantled and shipped to Baddeck, Nova Scotia. It was flown from the ice of Baddeck Bay, a sub-basin of Bras d'Or Lake, on 23 February 1909, making it the first controlled powered flight in Canada. The aircraft was piloted by one of its designers, Douglas McCurdy. The original ''Silver Dart'' was designed and built by the Aerial Experiment Association (AEA), formed under the guidance of Dr. Alexander Graham Bell. From 1891, Bell had begun experiments at Baddeck and Hammondsport to develop motor-powered heavier-than-air aircraft. By 1908, the success of the AEA was seen in a series of ground-breaking designs, culminating in the ''Silver Dart''. By the time the ''Silver Dart'' was constructed in late 1908, it was the Aerial Experiment Association's fourth flying machine. One of its p ...

AEA Cygnet
The Cygnet (or Aerodrome #5) was an extremely unorthodox early Canadian aircraft, with a wall-like "wing" made up of 3,393 tetrahedral cells. It was a powered version of the Cygnet tetrahedral kite designed by Dr Alexander Graham Bell in 1907 and built by the newly founded Aerial Experiment Association. Design and development Bell's experiments with tetrahedral kites had explored the advantages of utilizing great banks of cells to create a lifting body leading to the Cygnet I. On 6 December 1907, Thomas Selfridge piloted the kite as it was towed into the air behind a motorboat, eventually reaching a height of 168 ft (51 m). This was the first recorded heavier-than-air flight in Canada. While demonstrably able to fly as a person-carrying kite, it seemed unpromising as a direction for research into powered flight. It was difficult to control, and was in fact destroyed when it hit the water at the end of the flight. The following year, a smaller copy of the design was built as t ...

Frederick Walker Baldwin
Frederick Walker Baldwin (January 2, 1882 – August 7, 1948), also known as Casey Baldwin, paternal grandson of Canadian reform leader Robert Baldwin, was a hydrofoil and aviation pioneer and partner of the famous inventor Alexander Graham Bell. He was manager of Graham Bell Laboratories from 1909–32, and represented Victoria in the Nova Scotia Legislature from 1933–37, where he was instrumental in bringing about the creation of Cape Breton Highlands National Park. In 1908, he became the first Canadian and British subject to fly an airplane. Biography Born in Toronto, Ontario, Casey Baldwin was educated at Ridley College, where he held prominent student leadership roles, won the Blake Gold Medal, and was captain of the cricket team. In 1906, he graduated from the University of Toronto with a degree in electrical and mechanical engineering, and left for Baddeck, Nova Scotia, that summer to visit the home of his college friend Douglas McCurdy and the famous inventor Alexander G ...

John Alexander Douglas McCurdy
John Alexander Douglas McCurdy (2 August 1886 – 25 June 1961) was a Canadian aviation pioneer and the 20th Lieutenant Governor of Nova Scotia from 1947 to 1952. Early years Son of inventor Arthur Williams McCurdy and born in Baddeck, Nova Scotia, McCurdy was known as "Douglas". He was schooled at St. Andrew's College in Aurora, Ontario and graduated from the University of Toronto in mechanical engineering in 1907, where he had been a member of The Kappa Alpha Society along with his friend Frederick Walker Baldwin. The University of Toronto Year Book for his graduation yearTorontonensis1907) shows that he was active in rugby and fencing. Aviation In 1907, he joined Alexander Graham Bell's Aerial Experiment Association. In 1908, McCurdy helped another AEA member, Glenn Curtiss to set up the Curtiss Aeroplane and Motor Company. McCurdy became the first British subject to fly an aircraft in the British Empire when he piloted the Aerial Experiment Association's '' ...

Glenn Curtiss
Glenn Hammond Curtiss (May 21, 1878 – July 23, 1930) was an American aviation and motorcycling pioneer, and a founder of the U.S. aircraft industry. He began his career as a bicycle racer and builder before moving on to motorcycles. As early as 1904, he began to manufacture engines for airships. In 1908, Curtiss joined the Aerial Experiment Association, a pioneering research group, founded by Alexander Graham Bell at Beinn Bhreagh, Nova Scotia, to build flying machines. Curtiss won a race at the world's first international air meet in France and made the first long-distance flight in the U.S. His contributions in designing and building aircraft led to the formation of the Curtiss Aeroplane and Motor Company, which later merged into the Curtiss-Wright Corporation. His company built aircraft for the U.S. Army and Navy, and, during the years leading up to World War I, his experiments with seaplanes led to advances in naval aviation. Curtiss civil and military aircraft were some ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
