Savoia-Marchetti S.74
Savoia-Marchetti SM.74
History: In 1934 ordered the airline Ala Littoria at the company Savoia-Marchetti large, four-engine turboprop transport aircraft for 27 passengers and with a range of 1000 km. It was envisaged years back through the Alps and so should have the required wlan availability > yes.
The company has proposed hornoplošný aircraft with a spacious hull. All-wood wing was waterproof, the skeleton of the fuselage was of steel tubing covered with plywood. The chassis was solid.
The prototype of the I-URBE, powered by the engines of the Piaggio P-XRC Stella (515kW), first flew 16.11. 1934. The airline he took over in march 1935 and she put on the line to Paris. the aircraft fit the required 27 passengers, but most are flown with only 24. At each seat was a ventilator. In June 1935, took over the Ala Littoria second piece of I-ALPE, in December, then the last I-ROMA. The first was equipped with engines of the P-XRC, the second by british Bristol Pegasus III. These engines in Italy, produced under licence as the Alfa Romeo 126 and in 1938 they were equipped with all three specimens.
The aircraft served reliably on flights around Europe and to Africa. With the upcoming war, but were still more often sent to Africa, where they were supplied by the units on the egyptian border. After the outbreak of the war were included in state 604^Squadriglie and served mainly to transport cargo, e.g. at a distance of 500 km přepavily up to 5,000 kg of cargo, while standard třímotorové SM.75 took only half.
Intensive deployment type, however, bore the loss. As the first disappeared in October 1941, during a flight from Tripoli to Sicily plane 604-11 (ex-I-ALPE), and the aircraft 604-8 (ex-I-URBE) was shot down by his own spot in November. The longest so vydžel aircraft 604-9 (ex-I-ROMA). The first, in November 1941, survived the crash with .1007 and then, in April 1942, an attack of british bombers on the airport Gialo Libya. After nádále served to transport troops and meteriálu to and mainly from Africa. When it was needed to fit into the spacious trunk of up to 50 people, though some were stored in podpodlažním storage space.
Your destiny in the end the aircraft 604-9 found at the airport in Rome, where he was in July 1943 destroyed in an air raid.
