Caproni Ca.125

From Wikipedia, the free encyclopedia

The Caproni Ca.125 was a single engine, tandem two seat, touring biplane built in Italy in 1933. It could be operated either as a landplane or seaplane.

Design and development

The Ca.125 was a wire braced single bay biplane with slender, elliptical, unequal span wings; pairs of parallel interplane struts defined the bays and, because the lower wings had the greater span, these struts leaned inwards. The wings had neither stagger nor sweep. Ailerons were fitted only on the lower planes. In contrast to the elegant wingplan, the fuselage was deep and portly, in part a consequence of the enclosed, tandem cockpits. Since the canopies' 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 thrustline. As a result, the top of the cowling 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 shallow trailing edge cut-out 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 the tailplane mounted on top of the fuselage and braced to the lower longerons. The elevators were separate so that the rounded rudder could extend to the base of the fuselage and move between them. The fin was almost triangular. The fixed undercarriage was conventional, with mainwheels in spats mounted on V-form struts fixed to the fuselage sides just forward of the leading edge. Half-axles joined the wheels to the central fuselage underside. A Ca.125 idro version was also flown, its wheels replaced by a pair of duralumin floats, attached by struts to the lower fuselage^[1]
