Embodiment Construction
[0016] figure 1 The layer arrangement of the coating 6 applied to the propeller blade 1 is shown. The first adhesive layer 2 is arranged directly adjacent to the blade surface 1 . The polymer layer 3 is arranged on the adhesive layer 2 and is thus firmly fixed to the blade surface. The polymer layer 3 may comprise one or more rubber materials, such as neoprene. In addition, the polymer layer 3 may have a thickness in the range of, for example, 0.5 mm to 1.0 mm. On the neoprene layer 3 an adhesive coating 4 is arranged to provide a suitable surface for bonding a layer 5 of anti-icing material to the coating. The bond coat 4 may have a thickness of about 1 micron. The layer 5 of anti-icing material may have a thickness of about 3mm. The polymer layer 3 may be coloured, whereby wear of the layer of anti-icing material 5 and the coating 4 exposes the polymer layer to provide an indication of wear of the layer of anti-icing material 5 .
