Aviation includes the activities surrounding mechanical flight and the aircraft industry. Aircraft includes fixed-wing and rotary-wing types, morphable wings, wing-less lifting bodies, as well as lighter-than-air aircraft such as hot air balloons and airships.

Aviation began in the 18th century with the development of the hot air balloon, an apparatus capable of atmospheric displacement through buoyancy. Clément Ader built the "Ader Éole" in France and made an uncontrolled, powered hop in 1890. This is the first powered aircraft, although it did not achieve controlled flight. Some of the most significant advancements in aviation technology came with the controlled gliding flying of Otto Lilienthal in 1896; then a large step in significance came with the construction of the first powered airplane by the Wright brothers in the early 1900s. Since that time, aviation has been technologically revolutionized by the introduction of the jet which permitted a major form of transport throughout the world. (Full article...)

The feathered propellers of an RAF Hercules C.4
A propeller is essentially a type of fan which transmits power by converting rotational motion into thrust for propulsion of an aircraft through the air, by rotating two or more twisted blades about a central shaft, in a manner analogous to rotating a screw through a solid. The blades of a propeller act as rotating wings (the blades of a propeller are in fact wings or airfoils), and produce force through application of both Bernoulli's principle and Newton's third law, generating a difference in pressure between the forward and rear surfaces of the airfoil-shaped blades and by accelerating a mass of air rearward.

Selected biography

Elbert Leander "Burt" Rutan (born June 17, 1943 in Estacada, Oregon) is an American aerospace engineer noted for his originality in designing light, strong, unusual-looking, energy-efficient aircraft. He is most famous for his design of the record-breaking Voyager, which was the first plane to fly around the world without stopping or refueling, and the suborbital rocket plane SpaceShipOne, which won the Ansari X-Prize in 2004.

The Supermarine Spitfire was a single-seat fighter used by the RAF and many Allied countries in World War II.

Produced by Supermarine, the Spitfire was designed by R.J. Mitchell, who continued to refine it until his death from cancer in 1937. The elliptical wing had a thin cross-section, allowing a faster top speed than the Hurricane and other contemporary designs; it also resulted in a distinctive appearance. Much loved by its pilots, the Spitfire saw service during the whole of World War II, in all theatres of war, and in many different variants.

More than 20,300 examples of all variants were built, including two-seat trainers, with some Spitfires remaining in service well into the 1950s. It was the only fighter aircraft to be in continual production before, during and after the war.

The aircraft was dubbed Spitfire by Sir Robert MacLean, director of Vickers (the parent company of Supermarine) at the time, and on hearing this, Mitchell is reported to have said, "...sort of bloody silly name they would give it." The word dates from Elizabethan times and refers to a particularly fiery, ferocious type of person, usually a woman. The name had previously been used unofficially for Mitchell's earlier F.7/30 Type 224 design.

The prototype (K5054) first flew on March 5, 1936, from Eastleigh Aerodrome (later Southampton Airport). Testing continued until May 26, 1936, when Mutt Summers (Chief Test Pilot for Vickers (Aviation) Ltd.) flew K5054 to Martlesham and handed the aircraft over to Squadron Leader Anderson of the Aeroplane & Armament Experimental Establishment (A&AEE).
