Design

The Caproni Ca.11 was a high wing monoplane with a wooden structure and a canvas covering, equipped with a wing warping system to control the roll and reinforced by metal tie rods connected to the fuselage and to a special structure placed above it; the fuselage was based on a wooden lattice structure, in turn reinforced by metal cables, and was covered in cloth only for the front half; the same wooden structure with a canvas covering characterized the empennages. The trolley , fixed, was composed of two front wheels with anti-overblank pads and another smaller, tailed shoe. The Ca.11 differed from its immediate predecessors mainly for the engine , a French -made 7- cylinder star- shaped Gnome capable of developing a power of 50 hp.[1]

Operational use

The Ca.11 was a single-seater designed for training and for experimental military applications. The quality of the project and the construction, however, allowed the model to report several notable successes, with a series of speed records beaten in February 1912.

On 12 February, under the control of the pilot Enrico Cobioni , who had obtained his own flight license at the Caproni aviation school in Vizzola Ticino, a Ca.11 traveled 20 times, turning around in a circle, a closed circuit of 5 km , for a total of 100 km, in 66 min 30 s, thus establishing a new Italian record for the 100 km circuit (average speed of 90.225 km / h ) [4] for the 5 km in circuit (average speed of 91.370 km / h, corresponding to a time of 3 min 17 s); the record was approved by the commissioners Augusto Vogel and Gustavo Moreno.[2]

On 14 February the same pilot beat the Italian supremacy, rising to 1,150 m (moreover in a very short time of 15 minutes); during the same flight Cobioni covered 1,582 m in 53 s, touching a speed of 106.242 km / h and thus beating the national record straight.
