<p>The airfoil (10) has a main structure (15) including a spar (16), and a front structure (20) forming a leading edge (21), where an empty space (25) is formed between the main structure and the front structure. A rigid deflector element (30) is provided in the empty space, where the deflector element is fastened to the main structure. The deflector element includes a sharp edge (31) facing towards the front structure, so as to deflect an external obstacle i.e. bird impacting against the front structure, where the deflector element is not in contact with the front structure.</p> |
