A rotor blade () with adaptive twisting, the blade being provided with an outer covering () extending along a pitch variation axis (AY) from a first end zone () to a second end zone (), the outer covering () defining an internal cavity (). The blade includes a strip () extending inside said cavity () along said pitch variation axis (AY), said strip () comprising a composite material that is anisotropic so as to be suitable for twisting under the effect of centrifugal forces (F) directed parallel to said pitch variation axis (AY) when the blade () is in rotation, said strip () being fastened to said outer covering () via first and second fastener means () in order to be capable of twisting said outer covering ().
