The Nervures Valluna is a French single-place paraglider that was designed by Xavier Demoury and produced by Nervures of Soulom. It is now out of production.[1]
Valluna means "dream's door" in the Quechuan language.[2]
Design and development
[edit]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.[1]
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.[2]
The Valluna was replaced in production by the Nervures Faïal.[2]
