The Caproni Ca.66 alongside the Caproni Ca.67 were Italian-designed night bombers created to modernize the post-World War I fleet of the Regia Aeronautica.
Design and development
Constructed primarily from wood with a ply veneer and fabric finish, the Ca.66 was engineered specifically for nocturnal bombing missions. Its inverted sesquiplane wings, supported by streamlined struts and bracing wires, featured a single-bay layout with squared tips, uniform chord, and a slight dihedral angle of 3° 30' on the lower wings. The fuselage had a square cross-section tapering smoothly at the nose and accommodated four crew members in three open cockpits, with pilot and co-pilot seated side by side. At the rear, a large triangular fin with an attached rudder upheld the biplane tailplanes, which were also reinforced by struts. The undercarriage included a tail-skid and main wheels mounted on split axles, supported by struts beneath the engines and connected to the fuselage’s lower longerons. Control surfaces were conventional, featuring elevators on both upper and lower tailplanes, a substantial horn-balanced rudder, and horn-balanced ailerons exclusively on the lower wings.[1]
The Ca.67 closely resembled the Caproni Ca.66 in terms of general layout and wingspan but was equipped with two Lorraine-Dietrich 12Db engines and designed to carry a heavier load. Despite undergoing flight evaluations, it demonstrated no significant performance advantages over its predecessor, leading the Regia Aeronautica to refrain from placing production orders.[1]
Variants
- Ca.66
- A sesquiplane bomber with an inverted wing configuration, equipped with four 200–220 hp (150–160 kW) SPA 6A engines arranged in tandem pairs within strut-mounted nacelles positioned between the wings; only one unit was produced.
- Ca.67
- This model is a derivative of the Ca.66, featuring two 400 hp (300 kW) Lorraine-Dietrich 12Db (possibly Isotta Fraschini 12Db) engines installed in tractor-style nacelles on the lower wing; a single example was constructed.
