ELASTOMERIC RIBLETS

摘要

An array of aerodynamic riblets incorporates a high elongation elastomeric layer (201) having spaced tips (202) and optionally a protective cladding. The elastomeric layer may be adhered to an aerodynamic surface directly or as an appliqué in combination with one or more of an adhesive layer, one or more supporting polymer layers (208) and a metal foil layer (220).
