The Demoichelle was born in
2007, in the European ultralight show at Blois in France.
The APEV was here during the event with the Pouchel II of
the Corbeil-Essonnes high school. Next to the Pouchel was
standing a "Demoiselle", almost completed, built by some
students of the ESTACA (A french engineer school), based on
an American kit.
The aircraft was well built and she was gorgeous, but Daniel
was worried about the small size of the rear fuselage which
could mean a poor yawing moment. The construction procedure
of the Demoiselle was also not really "Chel" ! |

So, with his sheet
and tape measure, Daniel drew the first drawing of
the Demoichelle from the ESTACA's Demoiselle.
While back home,
Daniel made some more precise drawings of the
aircraft, equiping her with the system of mobile
wings, which avoid the construction of the ailerons,
because contrary to the Pouchels, the Demoichelle is
a 3 axis aircraft.
The wings of the
Demoichelle are the same as the wings of the Pouchel
Light. It means single spar, using 50x100mm
aluminium extrusion , wooden reinforced Styrodur
rib, composite leading and trailing edge, and DIATEX
1000 covering.
The
profile is the NACA 23112, perfect for the mobile
wings system. The Demoichelle do not have ailerons,
the control is made by a differential wing rotation
(+2?, -4?).
