Savoia-Marchetti SM.79 - Development

Development

The SM.79 project began in 1934 and was conceived as a fast, eight-passenger transport capable of being used in air-racing (the London-Melbourne race). Piloted by Adriano Bacula, the prototype flew for the first time on 28 September 1934. Originally planned to use the 597 kW (800 hp) Isotta-Fraschini Asso XI Ri as powerplant, the aircraft reverted to the less powerful 440 kW (590 hp) Piaggio P.IX RC.40 Stella, a license-produced Bristol Jupiter on which many Piaggio engines were based. The engines were subsequently replaced by Alfa Romeo 125 RC.35s (license-produced Bristol Pegasus).

The prototype (registration I-MAGO) was completed too late to enter the London-Melbourne race, but flew from Milan to Rome in just one hour and 10 minutes, at an average speed of 410 km/h (260 mph). Soon after, on 2 August 1935, the prototype set a record by flying from Rome to Massaua, in Italian Eritrea, in 12 flying hours (with a refuelling stop at Cairo). The SM.79 was by far the most important Italian offensive warplane of World War II, and one of the very few Italian aircraft to be produced in substantial quantities. Production started in October 1936 and continued until June 1943, totalling 1,217 machines. Some were constructed by Aeronautica Umbra of Foligno, makers of the AUT.18.

Famous quotes containing the word development:

    Sleep hath its own world,
    And a wide realm of wild reality.
    And dreams in their development have breath,
    And tears, and tortures, and the touch of joy.
    George Gordon Noel Byron (1788–1824)

    Good schools are schools for the development of the whole child. They seek to help children develop to their maximum their social powers and their intellectual powers, their emotional capacities, their physical powers.
    James L. Hymes, Jr. (20th century)

    On fields all drenched with blood he made his record in war, abstained from lawless violence when left on the plantation, and received his freedom in peace with moderation. But he holds in this Republic the position of an alien race among a people impatient of a rival. And in the eyes of some it seems that no valor redeems him, no social advancement nor individual development wipes off the ban which clings to him.
    Frances Ellen Watkins Harper (1825–1911)
