TheCaproni Ca.125 was a single-engine, tandem two-seat, touringbiplane built inItaly in 1933. It could be operated either as a landplane orseaplane.

Design and development

[edit]

The Ca.125 was awire bracedsingle bay biplane with slender, elliptical, unequal span wings; pairs of parallelinterplane struts defined the bays and, because the lower wings had the greater span, these struts leaned inwards. The wings had neitherstagger nor sweep.Ailerons were fitted only on the lower planes. In contrast to the elegant wing plan, thefuselage was deep and portly, in part a consequence of the enclosed, tandemcockpits. Since thecanopies' rooflines followed that of the upper fuselage, the crew sat low down, with poor forward views. The forward view was also hindered by the six-cylinder upright engine, which had to be placed high in the nose to properly locate the thrust line. As a result, the top of thecowling was at the same height as that of the windscreen; there was only a small gap between the screen and the rear of the engine.Cabane struts joined the wing centre section to the fuselage over the forward cockpit; a shallowtrailing edge cutout somewhat improved upward visibility from the rear seat.[1]

The Ca.125's fuselage was rounded in cross-section and tapered gradually to the tail. The tail surfaces were conventional, with thetailplane mounted on top of the fuselage and braced to the lowerlongerons. Theelevators were separate so that the roundedrudder could extend to the base of the fuselage and move between them. Thefin was almost triangular. The fixed undercarriage wasconventional, with mainwheels inspats mounted on V-formstruts fixed to the fuselage sides just forward of the wingleading edge. Half-axles joined the wheels to the central fuselage underside. ACa.125 idro version was also flown, its wheels replaced by a pair ofduraluminfloats, attached by struts to the lower fuselage[1]
