Supersonic passenger airliner
Aérospatiale-BAC Concorde is a retired turbojet-powered supersonic passenger airliner. First flown in 1969, Concorde entered service in January 1976 and continued commercial flights for 27 years. It was operated by British Airways and Air France and was retired in 2003 due to several unfavorable events. Only 20 aircraft were built.
Concorde (from the French word "condorde" meaning agreement, harmony) set several records (e.g. the fastest transatlantic flight, from Heathrow Airport, London to JFK Airport, New York, taking only 2 hours 52 minutes and 59 seconds ). It is considered a symbol of modern aviation even today.
Concorde had a very slender fuselage, a pointed droop-nose cone and characteristic delta wings. It was about 62 m (203.4 ft) long and 11 m (36.1 ft) wide, with a wingspan of less than 26 m (85.3 ft) and a wing area of 359 m² (3,864.2 ft²). Its empty weight was nearly 79 tonnes, while the maximum takeoff weight was 185 tonnes. It had a maximum fuel capacity of 119,500 l (31,569 gal).
The aircraft was capable of a maximum speed of about 2,368 km/h (1,471.4 mph or Mach 2.23), the average cruise speed was Mach 2.04, about 2,166 km/h (1,345.9 mph). Supersonic flight was permitted only above the ocean, not above inhabited areas. This incredible speed was provided by four Rolls-Royce/SNECMA Olympus 593 Mk 610 afterburning turbojet engines, each with a 169 kN (38,050 lbf) thrust.
The maximum operating altitude was 18,300 m (60,039 ft). Its staff consisted of nine members: three pilots and six flight attendants.
