Abstract

L'invention se rapporte à un élément d'essai (20) pour modéliser une aube (2) ou une pale d'un rotor (1), l'élément d'essai (20) comportant : - un support (21) comportant : • une partie inférieure (22) modélisant un pied d'aube ou un pied de pale, • une partie supérieure (23), - un élément d'équilibrage (30, 40) fixé à la partie supérieure (23) du support (21); l'élément d'essai (20) étant caractérisé en ce que l'élément d'équilibrage (30, 40) est déformable de sorte que lorsque l'élément d'essai (20) est monté sur un rotor (1) comportant une aube (2) ou une pale, le centre de gravité de l'élément d'essai (20) évolue en fonction de la vitesse de rotation du rotor (1), le centre de gravité (CG20) de l'élément d'essai (20) et le centre de gravité (CG2) de l'aube (2) ou de la pale étant symétriques par rapport à l'axe de rotation (X) du rotor (1)
