The Caproni Ca.101 was a three-engine Italian airliner which later saw military use as a transport and bomber. It was designed in 1927 and first flown in 1928.
The Ca.101 was a derivative of the Caproni Ca.97, with an enlarged airframe, which increased the payload from 574 kg (1,265 lb) to 800 kg (1,760 lb). This made the payload 20% of the maximum weight, compared to only 9% for the Ca.74G, which was heavier, smaller and inferior in performance.
Initially planned as a civil airliner, it was soon converted to the bomber/transport role. The aircraft was a typical 1920's design. It had three engines, one in the nose and one under each wing, high wings and a fixed undercarriage. The fuselage, of quadrangular cross-section, was made of steel tubes covered with fabric, as were the wings and tail. The floor was made of wood.
It was initially fitted with the 149 kW (200 hp) Armstrong Siddeley Lynx engine, driving a two-bladed metal propeller 2.88 m (9.45 ft) in diameter. The 1,200 l (317 US gal) fuel tank was located in the upper part of the central fuselage. Fuel was fed to the engines by means of copper pipes. All three engines had 44 L (12 US gal) of oil in a tank located behind the engine. The compressed air and fire extinguisher systems were also centrally located.
A variety of engines were used, sometimes with a composite layout: The Piaggio P.VII (276 kW/370 hp), the Alfa Romeo Jupiter (313 kW/420 hp), and other models of 179 kW (240 hp) and 201 kW (270 hp).
Exports of the Ca.101 were made to Australia, China and Paraguay. Hungary bought 20 aircraft for use as air mail aircraft.
The Ca.101bis, designed for use in Italy's colonies, had a slightly larger (56 m²/603 ft² wing area, 19.7 m/64.6 ft span and 13.54 m/44.42 ft length) and was heavier than the original model. It had an empty weight of 3,000 kg (6,610 lb), and a payload of 1,986 kg (4,378 lb).
It was fitted with an Alfa Romeo Jupiter in the nose, and an Armstrong Siddeley Lynx under each wing, giving it over 597 kW (800 hp) in total. The ceiling was improved to 5,500 m (18,045 ft), but the greater drag and weight reduced the maximum speed to 205 km/h (127 mph), and the endurance to only six hours.
The D2 version, was produced replacing the motors with three more powerful Alfa Romeo D.2 motors. In operations in Eritrea, they guaranteed good performance in the tropics. From the opening of hostilities in East Africa in 1935, various versions of the Ca. 101 were used during all of the conflict, carrying out tactical support missions for the infantry and bombing. The D.2 version, in particular, operated with the 14th Bomber Flight "Hic Sunt Leones" and 15th Bomber Flight "La Disperata" of the 4th Bombers Squadron.
