Design and development

The proper name and even the existence of this aircraft have been disputed in the past, but plans for the Type 02 high altitude fighter aircraft have since been found in the French Musée de l'Air. [1] Hauet [1] also refers to it as the C.02 and Green and Swanborough [2] as the Type O, though the latter was a quite different sports aircraft from 1914. [3]

The Type 02 was designed to fight at altitudes up to 9,000 m (29,500 ft) through a combination of engine power and flat airfoil section. [1] [2] It was a conventional single bay biplane with fabric covered, unswept, parallel chord wings ending in angled tips. The lower wing was smaller than the upper one, with a span reduced by 13% and a narrower chord. The wings had neither stagger nor dihedral and only the upper wing was fitted with ailerons. There was a pair of parallel, upright, streamlined interplane struts on each side, with the usual diagonal wire bracing. The upper wing was close to the fuselage, linked by four short, leaning cabane struts. [1]

The intention was to power the Type 02 operationally with either a 112 kW (150 hp) Gnome 9N or a 127–134 kW (170–180 hp) Le Rhône 9R engine, though for about fours months of initial testing it was fitted with a 89 kW (120 hp) Le Rhône 9Jb. All of these engines were nine cylinder rotaries. Photographs show neat, close fitted cowlings. [1] [2] Behind the engine the fuselage maintained a circular cross-section. The pilot's open cockpit was placed under the upper trailing edge, where there was a semi-circular cut-out to increase his upward field of view. The Type 02's tailplane was of unusually long chord and in plan was a highly swept delta, mounted on top of the fuselage. The fin was also wide and shallow, though less angular. It had an unbalanced rudder which reached down to the keel, operating in a nick in the elevators. There was a tailskid undercarriage with mainwheels on a single axle with a 1.50 m (4 ft 11 in) track, sprung from forward raked V-struts from the lower fuselage. [1]

First tests were made in November 1917, using the lower powered Le Rhône engine and flying from a base at 4,000 m (13,100 ft). [1] The more powerful Gnome engine was not tested until April 1918; [1] and the larger Le Rhône was also fitted that spring. [2] It is not known how many prototypes were built but the Type 02 did not enter production; it handled well but its performance and armament were not a significant improvement over those of the SPAD S.XIII, already in series production.

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.

The Caudron C.21 was a French twin engine biplane built just after World War I, able to carry three passengers in an open cockpit.

Caudron Types M and N

The Caudron Types M and N were small, fast French sports monoplanes, flown 1911–13 under a wide range of engine powers. There was also a military version.

The Caudron Type H was a collective name for three different Caudron designs of 1912-3. One of these was an amphibious three seat biplane built for the French military. Two were completed, one appearing at the Paris Aero Salon in November 1912.

Caudron Type L

The Caudron Type L was a two-seat French pusher configuration amphibious biplane, flown around 1913 and intended for naval use.

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 K was a French floatplane with a very powerful, twenty cylinder radial engine in pusher configuration. It took part in a French seaplane competition in 1913, but was lost in a take-off accident during the competition.

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

Caudron Type F

The Caudron Type F was a French single seat biplane produced just before World War I. A dozen were bought by China and at least two other examples, with different engines, competed in 1913, coming first and second in the biplane category of the cross-country race at Reims. Flown by Pierre Chanteloup, one was the first biplane to loop-the-loop.

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 Type E two seat trainer was a larger and more powerful development of the Type C. Two or three were bought by the French military and one by the Royal Navy just before World War I but its sales were overtaken by the superior Type G.
