The Caudron C.140 was a French sesquiplane designed in 1928 as a combination of liaison aircraft and observer and gunnery trainer.
Design and development
The C.140 was designed in the first half of 1928 to meet a French military call for a multi-purpose aircraft that could train pilots and gunners in gunnery and photographic and radio reconnaissance work as well as fulfilling a liaison role.[1][2]
It was a single bay, markedly unequal span biplane (sesquiplane). The upper wing was in three parts, with easily detachable, rectangular plan outer panels joined to a central panel which included a broad cut-out over the fuselage to enhance the upward view from the cockpits. The lower wings were similar but with the lower fuselage in place of the central panel. Both wings had two drawn rectangular section duralumin tube spars drilled for lightness, wooden ribs and round duralumin tube internal drag struts. Parallel pairs of outward-leaning interplane struts, again of round tubular duralumin, linked upper and lower wing spars aided by wire bracing. Similar parallel pairs of outward-leaning cabane struts joined the central panel to the upper fuselage longerons. There was no stagger or dihedral.[1][2]
The C.140 was powered by an uncowled 172 kW (230 hp) Salmson 9AB nine cylinder radial engine, mounted on duralumin bearers. In the case of a fire, the 200 L (44 imp gal; 53 US gal) fuel tank could be jettisoned in flight. Behind the engine the fuselage was of mixed construction and a deep oval in section with multiple longitudinal members. One of the open, tandem cockpits was under the rear of the wing and the rear one was close behind, about half way to the tail, where there was a shallow triangular fin with a parallel edged rudder with a tip continuing the upper fin line. The C.140 had a tail skid undercarriage, its main wheels on a single axle, sprung to two sets of steel V-struts to the lower wing root.[1][2]
