The Caproni PS.1, also known as the Pallavicino PS-1 and Caproni Ca.303, was an Italian four-seater sportsplane, designed and built specifically to compete in Challenge 1934, the European touring plane championships.[1]

Design and development

[edit]

The PS.1 was designed by Cesare Pallavicino, the former designer of Breda, after he had moved in 1933 to Caproni. Only two prototypes of the PS.1 were built, given registrations I-FRAN and I-MELO.

Description

[edit]

The Caproni PS.1 was a four-seat cabin aircraft of metal construction, with cantilever monoplane low wings. The steel-framed fuselage was covered with fabric as were the single-sparred trapezoidal planform foldable wings of steel construction which had rounded tips. The cabin had two side-by-side seats in front with dual controls, and two seats in the rear, under a common multi-part canopy. A retractable conventional landing gear with a rear skid was fitted with the mainwheels protruding from the wing's lower surface when retracted. The radial engine was fitted to the fuselage nose, enclosed by a cowling, driving a two-bladed propeller.[1] Fuel was housed in a 160-litre fuel tank.

Operational history

Both aircraft took part in the Challenge 1934 contest, flown by Armando François and Ugo Vincenzi. In a technical evaluation, the PS-1 took second place behind the Messerschmitt Bf 108 (the PS-1 and Bf 108 were the only Challenge aircraft with retractable landing gear). The aircraft were completed only shortly before the contest, so their pilots had little time for training. During a short landing trial, Vincenzi damaged his engine and propeller, and he had to withdraw. Armando François completed the contest in 18th place (for 34 starting and 19 finishing crews).[2]

The second PS.1, I-MELO, was rebuilt in the late 1930s and redesignated Caproni Ca.166, given the registration I-ALGU.
