The Savoia-Marchetti S.55 was an Italian double-hull flying boat from 1924.
history
The S.55 was designed as a torpedo bomber , mine-layer and passenger aircraft for the Italian Regia Aeronautica . The S.55 increasingly lost its military importance during its service life, but instead secured a place in aviation history as a reliable long-haul aircraft with numerous important journeys.
construction
The S.55 was an all-metal aircraft with one wing, two fuselages that also served as a float and a simple horizontal stabilizer with three vertical stabilizers. The tail unit was connected to the wing and the respective end of the fuselage via 2 tubular arms. The tail boom and rudder units were braced with wires for stabilization.
The two identical engines were installed in a nacelle above the center of the wing in a tandem arrangement with a pull and a push propeller. In the prototype, two Fiat A.12 engines with 300 hp each were installed in a streamlined engine nacelle, in 1925 Lorraine-Dietrich engines ( Lorraine-Dietrich 12 D ) with 400 hp were used, later also powerful Isotta Fraschini Asso 750 engines - in some cases completely undisguised.
The cockpit for the pilot and copilot was arranged in the wing under the engine nacelle.
The passengers sat in the two floats.
use
Immediately after its commissioning in 1924, it broke 14 records for speed, range and height. It was the first aircraft to cross the South Atlantic . Four months before Charles Lindbergh in February 1927, the flying boat called Santa Maria flew under Francesco de Pinedo from Dakar in Senegal to Pernambuco in Brazil .
In 1933, the Italian air marshal Italo Balbo organized an Atlantic overflight from 24 pages 55 to Chicago in order to exhibit it there at a large technology fair. Then the S.55s were used in the Italian and German air forces. They served as long-range bombers and patrol aircraft during World War II .
