Abstract
La présente invention concerne une amélioration d'un raidisseur d'aéronef en oméga. Le raidisseur comprend deux jambes (16, 18) dont l'une des extrémités est jointe par une aile (20) et dont chaque autre extrémité est prolongée respectivement par un pied (22, 24). Il comprend une nervure (32) faisant saillie par rapport à la surface de l'aile (20). Du fait du raidissement par nervure, les performances notamment en stabilité du raidisseur en M sont améliorées par rapport à un raidisseur en oméga.
