HISTORY
The Blériot XI is a French aircraft from the pioneer era of aviation. The first example was used by Louis Blériot to make the first flight across the English Channel in a heavier-than-air aircraft, on 25 July 1909. This is one of the most famous accomplishments of the pioneer era of aviation, and not only won Blériot a lasting place in history but also assured the future of his aircraft manufacturing business. The event caused a major reappraisal of the importance of aviation; the English newspaper The Daily Express led its story of the flight with the headline "Britain is no longer an Island".

It was produced in both single- and two-seat versions, powered by several different engines, and was widely used for competition and training purposes. Military versions were bought by many countries, continuing in service until after the outbreak of World War I in 1914. Two restored examples – one in the United Kingdom and one in the United States — of original Blériot XI aircraft are thought to be the two oldest flyable aircraft in the world.

DESIGN
The Blériot XI, largely designed by Raymond Saulnier,[2] was a development of the Blériot VIII, which Blériot had flown successfully in 1908. Like its predecessor, it was a tractor-configuration monoplane with a partially covered box-girder fuselage built from ash with wire cross bracing. The principal difference was the use of wing warping for lateral control. The tail surfaces consisted of a small balanced all-moving rudder mounted on the rearmost vertical member of the fuselage and a horizontal tailplane mounted under the lower longerons. This had elevator surfaces making up the outermost part of the fixed horizontal surface; these "tip elevators" were linked by a torque tube running through the inner section. The bracing and warping wires were attached to a dorsal, five-component "house-roof" shaped cabane consisting of a pair of inverted V struts with their apices connected by a longitudinal tube, and an inverted four-sided pyramidal ventral cabane, also of steel tubing, below. When first built it had a wingspan of 7 m (23 ft) and a small teardrop-shaped fin mounted on the cabane, which was later removed.

Like its predecessor, it had the engine mounted directly in front of the leading edge of the wing and the main undercarriage was also like that of the Type VIII, with the wheels mounted in castering trailing arms which could slide up and down steel tubes, the movement being sprung by bungee cords. This simple and ingenious design allowed crosswind landings with less risk of damage. A sprung tailwheel was fitted to the rear fuselage in front of the tailplane, with a similar castering arrangement.

When shown at the Paris Aero Salon in December 1908, the aircraft was powered by a 26 kW (35 hp) 7-cylinder R.E.P. engine driving a four-bladed paddle-type propeller. The aircraft was first flown at Issy-les-Moulineaux on 23 January 1909,[4] but although the aircraft handled well, the engine proved extremely unreliable and, at the suggestion of his mechanic Ferdinand Collin, Blériot made contact with Alessandro Anzani, a famous motorcycle racer whose successes were due to the engines that he made, and who had recently entered the field of aero-engine manufacture. On 27 May 1909, a 19 kW (25 hp) Anzani 3-cylinder fan-configuration (semi-radial) engine was fitted.[5] The propeller was also replaced with a Chauvière Intégrale two-bladed scimitar propeller made from laminated walnut wood. This propeller design was a major advance in French aircraft technology and was the first European propeller to rival the efficiency of the propellers used by the Wright Brothers.

During early July, Blériot was occupied with flight trials of a new aircraft, the two-seater Type XII, but resumed flying the Type XI on 18 July. By then, the small cabane fin had been removed and the wingspan increased by 79 cm (31 in). On 26 June, he managed a flight lasting 36 minutes 55 seconds, and on 13 July, Blériot won the Aero Club de France's first Prix du Voyage with a 42 km (26 mi) flight between Etampes and Orléans.
