ABSTRACT:
A series of streamlining elements surrounding a cable, pole, pipe or a similar long round member in a relatively moving fluid such as water or a high wind as an arrangement to reduce drag. Contiguous, independently rotatable elements are added easily to the cable to reduce drag forces by a factor of four or more and to provide some lift.
