Concorde

• Aérospatiale-BAC Concorde (play /ˈkɒŋkɔrd/) is a retired turbojet-powered supersonic passenger airliner, a supersonic transport (SST). It was a product of an Anglo-French government treaty, combining the manufacturing efforts of Aérospatiale and the British Aircraft Corporation. First flown in 1969, Concorde entered service in 1976 and continued commercial flights for 27 years.

• Among other destinations, Concorde flew regular transatlantic flights from London Heathrow (British Airways) and Paris-Charles de Gaulle Airport (Air France) to New York JFK and Washington Dulles, profitably flying these routes at record speeds, in less than half the time of other airliners.

• With only 20 aircraft built, their development represented a substantial economic loss, in addition to which Air France and British Airways (BA) were subsidised by their governments to buy them. As a result of the type’s only crash on 25 July 2000 and other factors, its retirement flight was on 26 November 2003.

• Concorde's name reflects the development agreement between the United Kingdom and France. In the UK, any or all of the type—unusual for an aircraft—are known simply as "Concorde", without an article. The aircraft is regarded by many as an aviation icon and an engineering marvel.

Development 

  Concept

• Concorde's final flight, G-BOAF from Heathrow to Bristol, on 26 November 2003. The extremely high fineness ratio of the fuselage is evident.

• In the late 1950s, the United Kingdom, France, United States, and Soviet Union were considering developing supersonic transport. The British Bristol Aeroplane Company and the French Sud Aviation were both working on designs, called the Type 223 and Super-Caravelle, respectively. Both were largely funded by their respective governments. The British design was for a thin-winged delta shape (which owed much to work by Dietrich Küchemann, then at the Royal Aircraft Establishment) for a transatlantic-ranged aircraft for about 100 people, while the French were intending to build a medium-range aircraft.

• The designs were both ready to start prototype construction in the early 1960s, but the cost was so great that the British government made it a requirement that British Aircraft Corporation (which had been formed in 1960 as a consolidation of British aircraft companies, including the Bristol Aeroplane Company) look for international co-operation. Approaches were made to a number of countries, but only France showed real interest. The development project was negotiated as an international treaty between the two countries rather than a commercial agreement between companies and included a clause, originally asked for by the UK, imposing heavy penalties for cancellation. A draft treaty was signed on 29 November 1962. By this time, both companies had been merged into new ones; thus, the Concorde project was between the British Aircraft Corporation and Aérospatiale. At first the new consortium intended to produce one long range and one short range version. However, prospective customers showed no interest in the short-range version and it was dropped.The consortium secured orders (i.e., non-binding options) for over 100 of the long-range version from the major airlines of the day: Pan Am, BOAC and Air France were the launch customers, with six Concordes each. Other airlines in the order book included Panair do Brasil, Continental Airlines, Japan Airlines, Lufthansa, American Airlines, United Airlines, Air India, Air Canada, Braniff, Singapore Airlines, Iran Air, Olympic Airways, Qantas, CAAC, Middle East Airlines and TWA.

• The design work was supported by a preceding research programme studying the flight characteristics of low ratio delta wings. The supersonic BAC 211 was modified for flight tests of the high speed flight envelope, the Handley Page HP.115 also provided valuable information on low speed performance
