L.Andersson Soviet Aircraft and Aviation 1917-1941 (Putnam)

Ansaldo A 300/3

   The Ansaldo A 300 reconnaissance and light bombing aircraft, a heavier and more powerful type than the earlier SVA models, was first flown in 1919. It was a two-bay biplane of normal wooden construction powered by a 300hp Fiat A 12bis engine. It had equal-span wings with unbalanced ailerons and a normal undercarriage. The A 300/2 was a two-seat version, while the A 300/3 had provision for a crew of three; pilot, gunner and observer. Armament consisted of a single machine-gun mounted in the rear cockpit. The A 300/4 model was adopted by the Italian Air Force as its standard reconnaissance type and a total of 612 were delivered from 1924/ 25. Most Italian reconnaissance units converted to the A 300 but apparently the Regia Aeronautica was not completely satisfied with this aircraft and it was replaced by other types after only a short period of service. About one hundred were converted to the A 300/6 with 410hp Fiat A 20 engines by the Gabardini company.
   Exports of the A 300 were made to the military air services of Belgium, China, Hungary (just a few), Mexico (one), Poland, Spain, the Soviet Union and Turkey (one). A substantial number of A 300s were built under licence in Poland, but the large-scale production contracts placed were soon cancelled and the Service career of the Polish A 300s was plagued by engine fires and structural failures.
   The Soviet order for Ansaldo aircraft placed in 1922 was to have included fifty examples of the A 300/3 three-seat version, but the number of aircraft ordered was eventually reduced to thirty (c/ns 7066-7095). The first consignment of sixteen SVA 10s and four A 300 aircraft was shipped to Odessa on board the Patras in April 1922 and by June all A 300s had arrived. The Ansaldo test pilot Botalla and three fitters assembled and test-flew the Italian aircraft at Odessa and in Moscow. The A 300s were assigned to the 1st Razvedivatel'naya eskadril'ya of the Aviatsionnaya Eskadra No. 2 at Kiev. This unit became the 3rd Otdel'naya razvedivatel'naya aviatsionnaya eskadril'ya in 1924. The NOA, the 1st Higher School of Pilots and the Higher School of Observers also had single examples of the A 300/3 and three were assigned to the Academv of the VVS in 1925.
   In 1925 the A 300s of the 3rd Otdel'naya razvedivatel'naya aviaeskadril'ya at Kiev were replaced by R-1s and passed on to the 14th and 17th Korpusnye aviaotryady, also at Kiev, and other units. In the spring of 1926 the A 300 was tested with the 250hp BMW IV engine and at least eighteen were converted to two-seat A 250/2s with this engine in 1926-27. From 1927 the Ansaldos were serving with the 17th and 37th Aviaotryady, also at Kiev, but they were finally replaced by R-ls in 1928. Relegated to the advanced training role they passed to the 2nd Combined School of Military Pilots and Mechanics at Vol'sk.
   In November 1927 Dobrolet and Ukrvozdukhput had been offered six to eight Ansaldos each, but there was no requirement for aircraft of this type in civil aviation. By the end of 1929 eighteen Ansaldos remained. All but two were written off in 1930 and the last disappeared during the following year.

Ansaldo A.300/C and 300/T

  The prototype Ansaldo A.300 single-engine two-seat military biplane first flew in 1919. Subsequent versions were the A.300/2 to A.300/6, and several hundred were built for military service. In 1921 two civil transport versions appeared, and these, together with some of the military aircraft, were built by Fiat.
  The first of the civil aircraft was the A.300/C, a two-bay strut and wire-braced biplane with accommodation for two pilots and four passengers. It is thought that the structure was of wood, although provision was made in the design for the use of steel longerons. The wings were of equal span, fabric-covered, and lower and upper wings were fitted with unbalanced ailerons. Two sets of diagonal struts ran from the centreline of the cabin walls outward to the upper and lower wings.
  The fuselage, which occupied the entire gap between the wings, was ply-covered in the cabin area and fabric-covered aft. Side-by-side pilots’ seats were in the front of the cabin, but the view was severely restricted by the engine cowling, which was unusually deep. There were two aft-facing and two forward-facing passenger seats.
  The tailplane was wire-braced and the rudder and elevators balanced. The undercarriage consisted of two sets of V struts attached beneath the diagonal wing struts, an aerofoil-section covered cross-axle and two sets of V struts which, in front view, formed a W.
  SNETA in Belgium acquired an A.300/C in 1921 which was registered O-BAHF (c/n C.6003). It passed to Sabena in 1923, but its registration was cancelled in November 1925. It is not known whether this was the prototype, although no other civil registered examples are known.
  The second version was the A.300/T. This had an eight-seat cabin, and the pilot was in an open cockpit behind the cabin. The wing area was increased, a curved decking added to the fuselage top and a biplane tail unit fitted. The bottom tailplane was placed lower on the fuselage than in the A.300/C and the upper tailplane was attached halfway up the fin. The upper and lower elevators were strut-connected at their inner ends.
  One A.300/T is known. It was registered I-ARNO, but there is no record of its entry into airline service.
  Both the A.300/C and A.300/T were powered by 300 hp Fiat A.12bis six-cylinder water-cooled inline engines which drove two-blade wooden airscrews.


A.300/C. Span 13-65 m (44 ft 9 1/2 in); length 9:65 m (31 ft 8 in); wing area 48 sq m (516-66 sq ft). Empty weight 1,470 kg (3,240 Ib); loaded weight 2,180 kg (4,706 Ib). Maximum speed 190 km/h (118 mph); ceiling 4,500 m (14,763 ft); endurance 3 1/2 hr.

A.300/T. Dimensions believed as A.300/C, but wing area increased to 51 sq m (548-95 sq ft), probably by elimination of cut-outs in lower wing centre section. Empty weight 1,400 kg (3,086 Ib); loaded weight 2,065 kg (4,552 Ib). Maximum speed 160 km/h (99:4 mph); ceiling 4,500 m (14,763 ft); endurance 3 1/2 hr.
