SNCASO Deltaviex
SNCASO · France · first flew 1954 · light aircraft
The SNCASO Deltaviex was a small French experimental jet aircraft with highly swept, small-span wings. It was designed to explore controlling roll and yaw with fine jets of air bled from the engine compressor.
Recognition (WEFT)
| W — Wings | Mid-mounted, swept |
|---|---|
| E — Engines | 1 × turbojet, fuselage-mounted |
| F — Fuselage | 7.1 m fuselage |
| T — Tail | Conventional |
WEFT is AircraftIQ's four-point recognition method — how it works.
Spot it by:
- Strongly swept, straight-tapered wing with 70 degrees of leading-edge sweep and very small span
- Tall swept fin with no rudder, controlled by air jets
- Single Turbomeca Marboré engine with intakes on the upper flanks over the wings
Look for a tiny jet with sharply swept, pointed wings, a tall fin without a rudder, tailplanes on the rear fuselage and tricycle landing gear.
Specifications
- The SNCASO Deltaviex has a length of 7.1 m (23 ft).
- It has a wingspan of 3.4 m (11 ft).
- Its maximum speed is 400 km/h (249 mph).
- Typical crew: 1.

History
The name came from the Delta VX design of Alliet at ONERA, and SNCASO built it at Courbevoie. Robert Fouquet first flew it on 30 April 1954, and the first flight with blown flaps followed on 21 September 1955.
Variants
Only one was built. Its cockpit canopy was modified at least once between 1954 and 1956, and a ventral fin replaced the early tail bumper wheel.
Where you'll see it
It was a research aircraft, tested at ONERA's airfield at Brétigny-sur-Orge. Despite its name it did not have a true delta wing.
