Airbus A300 - Design

Design

Airbus partners employed the latest technology, some derived from the Concorde. On entry into service in 1974, the A300 was a very advanced plane and influenced later subsonic airliner designs. The technological highlights include:

  • Advanced wings by de Havilland (later BAE Systems) with:
    • supercritical airfoil section for economical performance
    • advanced aerodynamically efficient flight controls
  • 5.64 m (222 in) diameter circular fuselage section for 8-abreast passenger seating and wide enough for 2 LD3 cargo containers side-by-side
  • Structures made from metal billets, reducing weight
  • First airliner to be fitted with wind shear protection
  • Advanced autopilots capable of flying the aircraft from climb-out to landing
  • Electrically controlled braking system

Later A300s incorporate other advanced features such as:

  • 2-man crew by automating the flight engineer's functions, an industry first
  • Glass cockpit flight instruments
  • Extensive use of composites for an aircraft of its era
  • Center-of-gravity control by shifting around fuel
  • Wingtip fences for better aerodynamics (first introduced on the A310-300).

All these made the A300 a substitute for the widebody trijets such as McDonnell Douglas DC-10 and Lockheed L-1011 for short to medium routes. On the early versions, Airbus used the same engines and similar major systems as the DC-10.

Famous quotes containing the word design:

    “Humility is often only the putting on of a submissiveness by which men hope to bring other people to submit to them; it is a more calculated sort of pride, which debases itself with a design of being exalted; and though this vice transform itself into a thousand several shapes, yet the disguise is never more effectual nor more capable of deceiving the world than when concealed under a form of humility.”
    —François, Duc De La Rochefoucauld (1613–1680)

    “To nourish children and raise them against odds is in any time, any place, more valuable than to fix bolts in cars or design nuclear weapons.”
    —Marilyn French (20th century)

    “We find that Good and Evil happen alike to all Men on this Side of the Grave; and as the principle Design of Tragedy is to raise Commiseration and Terror in the Minds of the Audience, we shall defeat this great End, if we always make Virtue and Innocence happy and successful.”
    —Joseph Addison (1672–1719)
