Aeronautica Umbra Trojani AUT.18

Aeronautica Umbra Trojani AUT. 18 History

The Italian air force during World War II (1939-1945) - Regia Aeronautica - relied on the large number of fighter types that emerged from modernization programs developed in the prewar period. The Aeronautica Umbra Trojani 18 or "AUT. 18" was another product from this period and was designed to meet the same flight service requirements as the FIAT G. 50, Macchi C. 200 and Reggiane Re. 2000.

However, it failed to impress and only completed the only prototype of the series.

Designed by Felice Trojani and ordered for a formal evaluation in 1936, the aircraft had a very traditional design with the engine in the nose, the cockpit above the center and a tail fin. The main aircraft is located amidships and mounted low on the side of the fuselage.

The limbs taper towards the rounded tips. The Pilot sits under a heavy-frame canopy, but still looks relatively good from the cockpit. The landing gear features a proven trailing shape that is designed to drive and retract. The structure of modern fighter jet designs is all metal.

Power is provided by an 18-cylinder FIAT A. 80 R. C. 41 series air-cooled radial piston engine producing 1,044 horsepower and driving a three-bladed propeller unit centered on an enlarged spinner.

The armament is centred on 2 x 12.7mm Breda SAFAT machine guns - unlike other Italian fighters of the time, these were mounted on the wing main aircraft (one per wing).

The first flight of the prototype (S/N M. M. 363) was recorded on April 22, 1939, and in early 1940 it was found that there were enough models to require additional modifications (including modified hoods). Additional flight tests followed until November 1940, but AUT. The 18 barely stands out in the crowded field of Italian monoplanes - two fighters already in production have been designated for service with Regia Aeronautica, the aforementioned FIAT G. 50 and Macchi C. 200 monoplanes. Hence, AUT.

18 was not further developed beyond its prototype form.

After build, AUT. The 18 has a barrel length of 28 feet, a wingspan of 37.8 feet, and a height of 9.4 feet. Curb weight reaches 5,110 lbs and maximum takeoff weight (MTOW) is 6,560 lbs. It has a top speed of 300 miles per hour and a range of up to 500 miles. Service is capped at 32,800 feet.

AUT. The 18 takes its name from a combination of names: manufacturer Aeronautica Umbra S.A. and designer Felice Trojani.
