| 摘要 |
The present invention relates to an aerofoil (20) comprising a leading edge portion (22) and a flexible thin-walled portion (26) that is rearwards of the leading edge portion, defining a cavity (28), and a shape-forming insert (30) for inserting into the cavity. The shape-forming insert at least partly defines the profile of the aerofoil such that changing the shape of the insert changes the profile of the aerofoil.
