Sud-Ouest Deltaviex
 
Deltaviex-1
 
The Deltaviex is an experimental aircraft designed by ONERA for development of supersonic aircraft. designed in 1953 by ONERA, the prototype was built by SNCASO in Courbevoie, under the direction of engineer Aliette.
 
The aircraft was intended for multiple testing, including a roll stabilization device obtained by the profile of the trailing edge landing flaps. This device was developed lift while providing propulsion. Conventional ailerons were located at the ends of the wings. At 3.40 m they were partly intended to produce a very low inertia and damping in roll. The jet was formed by air bled from the engine in a small proportion (about 2%). The system has a switchable ramp equipped with many output holes. The steering was done with an extremely short period of around five hundredths of a second, producing a flap ange of + / - 2 °. The 70° wing thickness does not exceed 6%. It is adjustable in flight to 1 ° -4 °. The tricycle undercarriage is retractable.
 
The Deltaviex made ​​its first flight in 1954 with Robert Fouquet at the controls. Testing remained secret until November 8, 1956, when the Deltaviex was introduced to the press.
 
During testing (at Brétigny, Meudon, and Modane), the Deltaviex changed canopy type three times.
