An aerofoil (10) having a leading edge (16) and a trailing edge (18), the leading edge (16) comprising a plurality of slits (22) extending toward the trailing edge (18), such that the leading edge (16) is defined by alternating peaks (28) and troughs (26). Each peak (28) extends in a generally spanwise direction (S) and defines a peak width (a), each peak (28) being separated from an adjacent peak (28) in the spanwise direction (S) by a trough (26). Each trough (26) extends in the generally spanwise direction (S) and is spaced in a chordwise direction (X) from the peak (28), each trough (26) defining a trough width (w). A ratio of the peak width to the trough width (a:w) is between 4:1 and 10:1.
