The A300B, otherwise known as the European Airbus, is an international collaborative project. Hawker Siddeley Aviation are under contract to Airbus Industrie to design and manufacture the wing. Manufacture is now well advanced, the first wing having been delivered to Toulouse in November 1971.

In describing the aerodynamic development of the wing for this aircraft, it is necessary to describe events before the advent of the designation A300B, as the aerodynamic design philosophy was established prior to that date. In particular reference will be made to the preceding paper project the A300 and to a lesser extent to projects being considered before the opening of technical discussions between Sud Aviation, Deutsche Airbus, and Hawker Siddeley Aviation.
