Il programma “ALFA” Medium Range Ballistic Missile

It/Eng.version

Alfa was the designation of an Italian ballistic missile program that started in 1971 under the control of the GRS (Gruppo di Realizzazione Speciale Interforze). Starting as a development effort for a study on efficient solid-propellant rockets, the Alfa rocket was planned as a two-stage rocket. Test launches with an upper stage mockup took place between 1973 and 1975, from Salto di Quirra.

The Alfa was 6.5 metres (21 ft) long and had a diameter of 1.37 metres (4 ft 6 in). The first stage of the Alfa was 3.85 metres (12.6 ft) long and contained 6 t of solid rocket fuel. It supplied a thrust of 232 kN for a duration of 57 seconds. It could carry one tonne warhead for a range of 1,600 kilometres (990 mi), placing European Russia and Moscow in range from the Adriatic Sea.

Italy has been active in the space sector since 1957, conducting launch and control operations from the Luigi Broglio Space Centre. The advanced Scout and Vega launchers currently used by the European Space Agency(ESA) derive their technological basis partially from Alfa studies.

Leonardo and the flight

Leonardo began to study the concept and the mechanics of flight, combining nature and engineering: the contamination of the disciplines is an aspect that recurs so often in Leonardo’s thought that it can be considered a real “trademark” of his genius.

Reasoning on the flight, observing the nature and the birds Leonardo had an intuition able to deviate him from the beliefs of the scientists of the time, who saw the flight as a mysterious and almost magical process. Leonardo, observing the movements of the birds, understood that in the flight there was nothing magical but only simple and mere mechanics.

The study of the conformation of the wings of the birds and the survey on the air currents made clear to Leonardo that the man’s flight was not an impossible undertaking, but reproducible with the right mechanics. Son of experience, Leonardo came to theorize in a very empirical way the principles of aerodynamics theorized only a long time later.

And here, one after the other, Leonardo designs instruments capable of supporting, on a theoretical level, human flight: the parachute, the aerial life (considered by many to be a prototype of the helicopter) and the many flying wings designed and built by Leonardo These are just a few examples of how the Tuscan genius tried to realize his greatest dream.

The flight, a dream in which Leonardo will have faith throughout his life despite the difficulties, failures and failures to which he constantly meets his greatest and desired undertaking, the one with which he was convinced to become immortal and remembered by posterity.

So it was not, but Leonardo da Vinci, to date remains one of the most brilliant personalities that history of art, science and engineering have ever known.
