| 摘要 | An airfoil (10) having a main structure (15) including at least one spar (16) and a front structure (20) forming a leading edge (21), said airfoil (10) having an empty space (25) between said main structure (15) and said front structure (20). The airfoil (10) includes a rigid deflector member (30) in said empty space (25), the deflector member being fastened to the main structure (15), said deflector member (30) having a sharp edge (31) facing towards said front structure (20) in order to deflect an external obstacle impacting against said front structure (20). | ||

| 主权项 | 1. An airfoil having a main structure including at least one spar and a front structure made of metal forming a leading edge, the airfoil having an empty space between the main structure and the front structure, wherein the airfoil includes a rigid deflector member in the empty space, the deflector member being fastened to the main structure, the deflector member having a sharp edge facing towards the front structure in order to deflect an external obstacle impacting against the front structure, the deflector member not being in contact with the front structure. | ||
