Anti-icing stack

An aerodynamic surface comprising an edge portion and an anti-icing stack disposed on the edge portion, wherein the anti-icing stack comprises:

• a first layer, a second layer and an additional layer, wherein the first layer is disposed between the second layer and the additional layer, wherein:
• the first layer comprises an elastomeric erosion protection layer having an elongation at break as determined according to ASTM test standard D882-12 of greater than 100%;
• the additional layer comprises a foam adhesive layer having a tensile modulus as determined according to ASTM test standard D882-12 of less than 5 MPa, the foam adhesive layer bonding the first layer to the edge portion of the aerodynamic surface, the foam adhesive layer having a thickness of at least 600 micrometers, wherein the thickness of the foam adhesive layer is at least 50% of a total thickness of the anti-icing stack, and
• the second layer comprises an anti-icing layer.
