Abstract
From 1959, aviation specialists began to see the great potential of supersonic commercial transport aircrafts. Air traffic was growing steadily and rapidly by then. While 100 billion passenger-kilometres were recorded in 1962, 222 billion were projected at this time for 1970. Long haul to medium distance (from 1 500 to 4 500 km) and long distance (over 6000km, which corresponds to a Transatlantic flight) was growing considerably. On such distances, supersonic aircraft would allow gaining valuable time and could be very profitable. Given the progress made, particularly in the construction of military aircrafts, such a project would not raise difficult technical problems to speeds below Mach 3....
