Sud-Ouest Triton

The Sud-Ouest SO.6000 Triton is an early experimental French jet aircraft. It has the distinction of being the first indigenously-designed jet-powered aircraft to be flown by the nation, having been designed and manufactured during the 1940s by the French aircraft construction consortium SNCASO.

Design and development
Origins According to aviation author Peter Caygill, France's aviation industry was in dire straits, perhaps having been more damaged than that of any other nation, as a consequence of events in the Second World War. Regardless, French industrialists and government officials alike were keen to make rapid advances in aviation technology to not only revive the nation's aviation capabilities, but to utilise the newest advances and produce a new generation of competitive indigenously-built aircraft. France, like the other Allied nations in the war, had benefitted from captured Germany high speed research; these factors combined gave a great impetus to undertaking advanced research projects. Design The SO.6000 was, despite the use of jet propulsion, an otherwise conventional aircraft. It was a compact and unarmed two-seater, having a deep-set fuselage and furnished with a mid-mounted straight wing. The spacious fuselage provided sufficient space for multiple engine models to be readily accommodated. Caygill observed that while SNCASO had to start from scratch on the fuselage's design, by pursuing a clean-sheet approach and the originality which that entailed, the SO.6000 lacked much of the conservatism present in the contemporary designs of several British aircraft manufacturers. While having been envisioned from the onset to be powered by a jet engine, the availability of such a powerplant to install upon the aircraft was no straightforward issue. At one stage, it had been planned for the type to receive a French-designed Rateau-Anxionnaz GTS-65 turbojet engine. However, as a result of the delays encountered in the development of this engine, it was decided to instead adopt the German-designed Junkers Jumo 004-B2 engine for use upon the first prototype. The choice of a German engine was opted for as a means of preventing any unnecessary delay in the project. ==Operational history==
Operational history
On 11 November 1946, the first prototype performed its maiden flight, conducted by test pilot Daniel Rastel amid unfavourable weather conditions. None of the aircraft would be powered by the intended GTS-65 engine, the development of which would eventually be terminated without any production examples being completed. When flown with the Nene engine, the SO.6000 was capable of achieving speeds of up to 593 mph, but was also beset by several vibration and stability issues when flown near these speeds. The SO.6000's lead designer, Lucien Servanty, also worked on another aircraft during the late 1940s, the Sud-Ouest Espadon, which became France's first post-war jet fighter; he also participated in the design of numerous aircraft following this, including the Anglo-French supersonic airliner Concorde. Further development of the SO.6000 was ultimately abandoned during the early 1950s without any direct follow-on; as such, the SO.6000 was never use in any operational circumstance. The type had been rendered obsolete by the rapid pace of advancements, both in terms of jet propulsion specifically and wider aerospace capabilities generally, with numerous jet-powered designs being produced around this timeframe. ==Variants==
