The Breguet Type I was an experimental aircraft built in France in 1909. It was Louis Breguet's first fixed-wing aircraft design. [1] [2] Breguet had previously had some success with two helicopter designs, one of which had been exhibited at the Paris Aero Salon in December 1908. Because of these machines, the Type I was at first known as the Breguet Type III.

Design

The Breguet Type 1 differed from most biplane designs of the time by being of tractor configuration and not having a forward elevator, as used by the Wright Brothers and Gabriel Voisin. The engine was mounted at the front of the aircraft in a square section nacelle projecting forwards from the lower wing, driving a three-bladed propeller. The upper wing was built in three separate sections, with the entire outer sections pivoting about the main spar for control purposes, while the lower wings, which had a smaller wingspan, were divided into two pivoting planes, with a large gap between them in place of a centre section. The wings were connected by four steel tube interplane struts, each enclosed in a streamlined fairing. The tail surfaces were mounted on four cross-braced steel booms and consisted of a large-span upper elevator and a smaller lower surface, with a pair of rudders filling the gap between them. The undercarriage consisted of a pair of forward-projecting skids with a small wheel mounted between them, supplemented by outrigger wheels on each wingtip. Power was provided by a 60 hp (45 kW) Renault V-8 engine.

Tractor configuration arrangement of propellers on an aircraft to face forward

An aircraft constructed with a tractor configuration has the engine mounted with the airscrew in front of it so that the aircraft is "pulled" through the air, as opposed to the pusher configuration, in which the airscrew is behind and propels the aircraft forward. Through common usage, the word "propeller" has come to mean any airscrew, whether it actually propels or pulls the plane.

Gabriel Voisin French aviation pioneer

Gabriel Voisin was an aviation pioneer and the creator of Europe's first manned, engine-powered, heavier-than-air aircraft capable of a sustained (1 km), circular, controlled flight, which was made by Henry Farman on January 13, 1908 near Paris, France. During World War I the company founded by Voisin became a major producer of military aircraft, notably the Voisin III. Subsequently, he switched to the design and production of luxury automobiles under the name Avions Voisin.

Wingspan distance from one wingtip to the other wingtip of an airplane or an animal (insect, bird, bat)

The wingspan of a bird or an airplane is the distance from one wingtip to the other wingtip. For example, the Boeing 777-200 has a wingspan of 60.93 metres, and a wandering albatross caught in 1965 had a wingspan of 3.63 metres, the official record for a living bird. The term wingspan, more technically extent, is also used for other winged animals such as pterosaurs, bats, insects, etc., and other fixed-wing aircraft such as ornithopters. In humans, the term wingspan also refers to the arm span, which is distance between the length from one end of an individual's arms to the other when raised parallel to the ground at shoulder height at a 90º angle. Former professional basketball player Manute Bol stands at 7 ft 7 in (2.31 m) and owns one of the largest wingspans at 8 ft 6 in (2.59 m).

The machine was displayed without an engine at the Olympia Aero Show in London in March 1909 [3] and first took to the air on 28 June. [2] Breguet flew this aircraft, given the exhibition number 19, at the Grande Semaine d'Aviation in August, [4] but crashed when the machine was caught in a gust of wind . Breguet himself was unharmed. [5]

Farman III early French aircraft designed and built by Henry Farman in 1909

The Farman III, also known as the Henry Farman 1909 biplane, was an early French aircraft designed and built by Henry Farman in 1909. Its design was widely imitated, so much so that aircraft of similar layout were generally referred to as being of the "Farman" type.

The Latécoère 14 and Latécoère 16 were similar French passenger and postal aircraft of advanced design built in 1923. They differed chiefly in engine power. Only one of each was constructed. The 14's type number was reused for an unrelated parasol wing prototype that was basis of the more successful Latécoère 17.

Santos-Dumont Demoiselle

The Santos-Dumont Demoiselle was a series of aircraft built in France by world aviation pioneer Alberto Santos-Dumont. They were light-weight monoplanes with a wire-braced wing mounted above an open-framework fuselage built from bamboo. The pilot's seat was below the wing and between the main wheels of the undercarriage. The rear end of the boom carried a tailwheel and a cruciform tail.

Latécoère 4

The Latécoère 4 was a three-engined, 15-passenger biplane built in France in the early 1920s. It proved difficult to fly and was discontinued, though a second machine was completed as the Latécoère 5 bomber.

The Short No.2 was an early British aircraft built by Short Brothers for J.T.C. Moore-Brabazon. It was used by him to win the £1,000 prize offered by the Daily Mail newspaper for the first closed-circuit flight of over a mile (1.6 km) to be made in a British aircraft.

Breguet Type IV utility aircraft

The Breguet Type IV was an aircraft built by Breguet Aviation. It was first flown in 1911, and was the first Breguet aircraft to be produced in quantity. It was used by the French Army and the R.F.C.. It is notable for the extensive use of metal in its construction, unusual in an aircraft of its time.

Howard Wright 1909 Biplane

The Howard Wright 1909 Biplane was an early British experimental aircraft designed and built by Howard T Wright. It was displayed at the first Aero Show at Olympia in March 1909, and although only one was built, it was the first of a series of aircraft built by Wright that were to earn him brief fame as one of England's foremost aircraft manufacturers in the early years of flight.

Cody Michelin Cup Biplane

The Cody Michelin Cup Biplane was an experimental aircraft designed and built in Britain during 1910 by Samuel Franklin Cody, a prominent showman and aviation pioneer. Cody had worked with the British Army on experiments with man-lifting kites and in October 1908 had successfully built and flown the British Army Aeroplane No 1, making the first officially verified powered flight in the United Kingdom. Cody broke the existing endurance record twice in the aircraft, the second flight, made on 31 December 1910, winning him the Michelin Cup for the longest-lasting flight made over a closed circuit in the United Kingdom before the end of the year.

The Vickers E.F.B.1 'Destroyer' was an early British military aircraft prototype.

Short S.36

The Short S.36 was a British two-seat tractor biplane, built by Short Brothers for Frank McClean in 1911. It was later developed into the Short S.41 and Short S.45, which were the first of a long series of similar aircraft built for the RNAS and RFC.

During 1910 the Caudron brothers were briefly associated with the Société Anonyme Français d'Avaiation (S.A.F.A.), and an example of the type was exhibited at the 1910 Paris Aero Salon as the S.A.F.A. Biplane.

The Breguet Type II was the second fixed-wing aircraft design produced by Louis Breguet. Built during late 1909, it was soon discarded in favour of his next design, the Breguet Type III

Breguet Leviathan

The Breguet Leviathan was a family of large all-metal biplane aircraft built in France in the early 1920s. The Breguet XX and XXI were notable for being powered by Breguet-Bugatti multiple engines, in two forms. The Breguet XXI was powered by individual Breguet-Bugatti U.16 engines initially and Lorraine-Dietrich 8b engines in tandem later. The Breguet XXII had accommodation for about twenty passengers and was destroyed during a 1923 transport aircraft competition. Development of all three aircraft types was halted largely due to technical issues with power-plants and aircraft structure.
