Design and development
The Valluna was designed as an intermediate glider and was one of the first gliders to be certified to the then-new CEN standards. The models are each named for their relative size.
The Valluna Bivouac was designed as a lighter weight version of the basic Valluna for
bivouac flying. The Valluna II reduced line drag through the use of fewer and unsheathed lines. It was not certified.
The Valluna was replaced in production by the
Nervures Faïal.

Glide ratio
In aerodynamics, the lift-to-drag ratio (or L/D ratio) is the lift generated by an aerodynamic body such as an aerofoil or aircraft, divided by the aerodynamic drag caused by moving through air. It describes the aerodynamic efficiency under give ...
