Aircraft surface coatings for drag reduction/erosion protectionThe laboratory testing of a large number of films and liquid coatings for aircraft drag reduction and erosion protection has led to the identification of elastomeric polyurethanes, which fulfil smoothness, durability and protection requirements while being easily applied to large, compound-curvature areas with standard spray equipment. It was found that an epoxy primer produced a stronger bond between coating and substrate than a wash primer. A drag-reduction value of 0.2% was achieved with a commercially-available elastomeric polyurethane.
