Abstract

L'invention concerne un dispositif d'atterrissage pour aéronefs, en particulier pour hélicoptères. Le dispositif de l'invention est passif et se caractérise essentiellement en ce que son élasticité et son amortissement en roulis sont indépendants de son élasticité et de son amortissement pour des mouvements verticaux. Le dispositif de l'invention permet, grâce à cette indépendance, d'affaiblir au mieux le choc à l'atterrissage et l'instabilité par résonance du soL
