Concorde was jointly developed and manufactured by The original programme cost estimate was £70 million.Concorde won the 2006 Great British Design Quest, organised by the BBC and the The origins of the Concorde project date to the early 1950s, when At the time it was known that the drag at supersonic speeds was strongly related to the span of the wing.This same short span produced very little lift at low speed, which resulted in extremely long take-off runs and frighteningly high landing speeds.Küchemann's and Weber's papers changed the entire nature of supersonic design almost overnight. The Committee ultimately rejected the economic arguments, including considerations of supporting the industry made by Thorneycroft. There also had been a wind shift before takeoff, resulting in an undesirable tailwind. I think it's absolutely amazing and here we are, now in the 21st century, and it remains unique.Because of the way Concorde's delta-wing generated lift, the undercarriage had to be unusually strong and tall to allow for the angle of attack at low speed. Air France flight 4590 taking off with fire trailing from its engine, Paris, July 25, 2000. Bristol's original Type 198 was a small design with an almost pure slender delta wing,To test the new wing, NASA privately assisted the team by modifying a By this time similar political and economic concerns in France had led to their own SST plans.
The nozzle ejector (or aerodynamic) design, with variable exit area and secondary flow from the intake, contributed to good expansion efficiency from take-off to cruise.Concorde's Air Intake Control Units (AICUs) made use of a digital processor to provide the necessary accuracy for intake control. In 1983, BA's managing director, Research revealed that passengers thought that the fare was higher than it actually was, so the airline raised ticket prices to match these perceptions.Its estimated operating costs were $3,800 per block hour in 1972, compared to actual 1971 operating costs of $1,835 for a 707 and $3,500 for a 747; for a 3,050 nmi London–New York sector, a 707 cost $13,750 or 3.04c per seat/nmi, a 747 $26,200 or 2.4c per seat/nmi and the Concorde $14,250 or 4.5c per seat/nmi.Between March 1984 and March 1991, British Airways flew a thrice-weekly Concorde service between London and Miami, stopping at Washington Dulles International Airport.In 1997, British Airways held a promotional contest to mark the 10th anniversary of the airline's move into the private sector. The British government had lost money operating Concorde every year, and moves were afoot to cancel the service entirely. Due to weight considerations Air France removed 8 seats after the safety modifications of CY2000–2001.Other estimates of total program cost exceeded £2 billion. … Every one of them would have to be remanufactured and replaced. … And if you got them all together, what sort of testing regimen would be there? Air France flight 4590, flight of a Concorde supersonic airplane that crashed in Gonesse, a suburb of Paris, on July 25, 2000. At Additionally, due to the high average take-off speed of 250 miles per hour (400 km/h), Concorde needed upgraded brakes.

No. 3382, p.4After the Paris accident in 2000 Concorde was fitted with improved tyres uprated to 290 mph (470 km/h). -Ricky Bastin, Concorde EngineerQuote: "Airbus, the manufacturer of Concorde, has said it is becoming uneconomic to maintain the ageing craft and that it will no longer provide spare parts for it. Despite this, the government was not keen to continue. History Office, Ames Research Center. Both of these issues were resolved by active ratio changes between the inboard and outboard To fly non-stop across the Atlantic Ocean, Concorde required the greatest supersonic Nevertheless, soon after Concorde began flying, a Concorde "B" model was designed with slightly larger fuel capacity and slightly larger wings with Concorde's high cruising altitude meant passengers received almost twice the While subsonic commercial jets took eight hours to fly from New York to Paris, the average supersonic flight time on the transatlantic routes was just under 3.5 hours.
A draft treaty was signed on 29 November 1962.Reflecting the treaty between the British and French governments that led to Concorde's construction, the name At first, the new consortium intended to produce one long-range and one short-range version. "It is the world's most efficient jet engine." The promotion was a lottery to fly to New York held for 190 tickets valued at £5,400 each, to be offered at £10. The economic considerations were considered highly questionable, especially as these were based on development costs, now estimated to be £150 million, which were repeatedly overrun in the industry. [But] the manufacturing facilities are just not there.
However, this proved not to be the barrier it might seem; common components could be used in both designs, with the shorter range version using a clipped fuselage and four engines, the longer one with a stretched fuselage and six engines, leaving only the wing to be extensively re-designed.While the development teams met, French Minister of Public Works and Transport When the STAC plans were presented to the UK cabinet, a very negative reaction resulted. On June 12, 2003, Air France honored that agreement, donating Concorde F-BVFA to the Museum upon the completion of its last flight. Technically this means that IranAir did operate a Concorde service, despite it being a wet lease operation. Sud made minor changes to the paper, and presented it as their own work.Unsurprisingly, the two teams found much to agree on.
