The Carmier Simplex 10 hp was a French tailless, low-powered, single-seat aircraft built in 1923 for a contest arranged by a Paris newspaper. Only one is known to have been completed and its career was brief.

Recognition (WEFT)

W — Wings	High-mounted, swept
E — Engines	1 × piston, nose-mounted
F — Fuselage	3.8 m fuselage
T — Tail	No tailplane

WEFT is AircraftIQ's four-point recognition method — how it works.

Spot it by:

Tailless single-seat cantilever monoplane
Thick rectilinear wing with a leading edge swept at 20 degrees and an unswept trailing edge
Inner trailing edge occupied by broad-chord elevator-like surfaces with a rudder cut-out

The 12 kW Sergant A four-cylinder inline engine is in the nose, with a single open cockpit at about two-thirds of the root chord. A triangular fin runs from the cockpit to the trailing edge.

Specifications

History

It followed earlier tailless designs by René Arnoux, now with Pierre Carmier as chair and principal designer of the company "L'avion Simplex". It was designed for a low-power aircraft contest organised by the newspaper Petit Parisien, and it was built in the first half of 1923.

Variants

There were at least two tailless Simplex monoplanes, one with a 320 hp Hispano-Suiza V-8 built for the 1922 Coupe Deutsch. The names Arnoux, Carmier and Simplex have been applied to the types without distinction.

Where you'll see it

It began the initial trials of the Petit Parisien contest in July 1923, piloted by Geogel, but suffered engine problems and failed to qualify.
