This article is about the aircraft. For the diesel engine, see Fiat AN.1.

The Fiat AN.1 was an Italian two-seat biplane introduced in 1930, primarily recognized for showcasing Fiat's inaugural aircraft diesel engine, which bore the same designation, Fiat AN.1.

Design and development

Conceived as a two-seat reconnaissance aircraft, the AN.1 was developed to assess the feasibility of utilizing diesel engines for extended-range missions. During the early 1930s, diesel powerplants were considered advantageous for long-distance operations due to their enhanced reliability stemming from simpler mechanical construction, as well as reduced fuel consumption attributed to higher thermodynamic efficiency. Moreover, the use of heavy oil fuel eliminated fire hazards and was significantly more economical, costing approximately one-fifth of petrol at that time.

The power unit installed in the AN.1 was a Fiat-manufactured engine sharing its name with the aircraft. This engine incorporated components from the Fiat A.12 gasoline engine but featured a redesigned upper section adapted for compression ignition. The aircraft itself followed a traditional biplane configuration, though detailed specifications remain scarce. Its maiden flight occurred in 1930.

Operational history

Following initial brief test flights conducted at Fiat's facilities in Turin, the AN.1 embarked on its first notable long-distance journey in June 1930. Piloted by Renato Donati, it covered roughly 510 km (315 mi) en route to Rome. The flight concluded at Littorio Airport, where the aircraft was showcased during the opening day of the Aerial Pageant.
