Design and development

Between 1919 and 1922 Caudron built a series of multi-engined civil passenger transport biplanes of similar design but increasing size and engine power, the C.33, C.37, C.39, C.43 and C.61. [1] The C.37 was the first trimotor in this series. [2]

The C.37 was a three bay biplane with fabric-covered, rectangular-plan wings mounted without stagger. The lower wing had dihedral outboard of the engines, and the upper carried the ailerons, which were not balanced as they were on the later aircraft. The wings were joined by vertical pairs of interplane struts, the forward members attached near the leading edges, and the centre section was supported by similar, shorter cabane struts from the upper fuselage. Each inner bay was defined by two close pairs of leaning interplane struts, supporting an 60 kW (80 hp) Le Rhône 9C nine-cylinder rotary engine about halfway between the wings. Each wing-mounted engine was in a long, tapered cowling, open at the rear. There was a third cowled Le Rhône in the nose. The airliner could fly on only two engines when carrying six passengers. [2]

Behind the engine the fuselage was flat-sided, with a wide, open cockpit with its windscreen immediately under the upper leading edge. With a useful load of 450 kg (992 lb) the C.37 was capable of carrying six passengers, though it is not certain if windows or seats were fitted. Behind the wings the fuselage tapered gently to a broad, triangular fin which carried a vertical-edged rudder that reached down to the keel. The tailplane was mounted on top of the fuselage so its elevators had a notch for rudder movement. [2]

The C.37 had a fixed tailskid undercarriage. There were pairs of main wheels mounted on single axles attached at their centre to a longitudinal bar held under the engine at each end on short, forward-raked V-struts. To prevent nose-overs, there was a fifth wheel mounted under the nose. [2]

Caudron C.68

The Caudron C.68 was a two-seat French training and touring aircraft, built in the early 1920s, which attracted interest at the time because of its simple and fast wing folding arrangement. Only a few were produced.

Caudron C.65

The Caudron C.65 was a single seat biplane floatplane designed and built in France in 1922. Only one was completed.

Caudron C.43

The Caudron C.43 was the first French five-engined aircraft, a biplane intended for passenger transport or military use and multi-engined for safety. A development of the three-engined Caudron C.39, it had one tractor configuration engine in the nose and two push-pull pairs between the wings. It was capable of carrying eight passengers but was not developed.

Caudron C.39

The Caudron C.39 was a French three-engined biplane with a cabin for six passengers when the aircraft was equipped as a landplane or four passengers when on floats. It was flown with some success in competitions in 1920 and 1921.

Caudron C.33

The Caudron C.33 "Landaulet Monsieur-Madame" was a French twin engined biplane with four seats, two in open cockpits and two in an enclosed cabin.

Caudron C.25

The Caudron C.25 was a large, three-engined, biplane airliner, designed and built in France soon after the end of World War I. Its enclosed cabin could accommodate up to eighteen passengers.

The Caudron C.22 was a French twin engine night bomber built in 1917. It did not reach production.

The Caudron Type B was a 1911 development of the earliest Caudron type, the Caudron Type A, with a nacelle style fuselage and more powerful engine. Initially an equal span biplane, it was modified into a sesquiplane.

The Caudron Type B Multiplace was a large French biplane designed to carry up to five passengers in a cross country time trial of 1912. It was destroyed early in the event.

The Caudron Type C was a single seat French biplane, intended for military evaluation. Two were built in 1911.

Caudron Type D

The Caudron Type D was a French pre-World War I single seat, twin-boom tractor biplane, a close but slightly smaller relative of the two seat Caudron Type C. More than a dozen were completed, one exported to the United Kingdom, where they may also have been licence built, and three to China.

The Caudron C.92 was a passenger transport built by Caudron in 1925, powered by a 370 hp (280 kW) Lorraine-Dietrich 12D. Only one was built, and it was discarded in July 1934.
