R.Abate,G.Alegi,G.Apostolo Aeroplani Caproni: Gianni Caproni and His Aircraft, 1910-1983

In February 1911 Caproni met ingegner Agostino De Agostini, a prominent figure in business and industrial circles. From this stemmed the forming of the Ingg. De Agostini & Caproni Aviazione company, which found a new base at Vizzola Ticino, in part with help from Gherardo Baragiola who already had the use of some land with a small hangar for his Bleriot monoplane. The following months saw the addition of three sheds with the necessary tools, which were used to build the first Caproni monoplane which the Swiss pilot Enrico Cobioni would test in mid June. Flight training activity was developed in parallel with production, with a considerable flow of Italian and foreign student pilots. Despite this the company was short lived and, with De Agostini’s withdrawal, Caproni remained alone.

Caproni Prewar Designs

  Ca.8 - 1911 Single-seat monoplane with 25 hp Anzani engine; several were built for use by the training establishments.
  Ca.9 - 1911 Monoplane similar to Ca.8, but with a 35 hp Anzani engine. This aircraft was used on January 30, 1912 to set world records for distance and duration in closed circuit for aircraft with power below 40-hp.
  During 1912, an the military airfield of Somma Lombardo (Cascina Malpensa) was the headquarters of the piloting school. Commanded by cap. Gustavo Moreno, the school’s instruction and training were carried out with Nieuport-Anzani 35 hp monoplane and Caproni aircraft with the same engine (Ca. 9).
  Ca.10 - 1911 Ca.9 transformed into a two-seater.
  Ca.11 - Two-seater monoplane similar to Ca.10, equipped with a 50-hp Gnome rotary engine. It was used to set the Italian speed record of 106.242 km/h on February 12, 1912. Several specimens were reportedly purchased by the military prewar for use as trainers. They were definitely used at the Caproni aviation school in Vizzola where they were used to train civilian and military pilots.

  Ca.12 - Similar to the Ca.11, but with a 60 hp Anzani engine. On March 1912 it set a world speed record in closed circuit of 300 km in 2h 49 minutes. Three months later it was used to set an Italian record for flight duration with a single passenger in a closed circuit of 3 hours 12 minutes.

  Ca.13 - Identical to the previous Ca.12, but was a single-seater with a 70-hp Anzani engine. Fitted with wings that had a smaller span, the Ca.13 reached 130 km/h in testing. In June 1912, the Ca.13 was flown in the international competitions in Vienna; it was the only Italian aircraft that competed.
