THE EFFECT OF A ROTATING CYLINDER AT THE LEADING AND TRAILING EDGES OF A HYDROFOIL

Abstract : An experimental investigation was conducted in the High Speed Water Tunnel at the California Institute of Technology on the lift, drag, and moment produced by a rotating cylinder in the leading and trailing edges of a hydrofoil. It was found that with the cylinder in the leading edge, only a small increase in lift was developed, while with the cylinder in the trailing edge a much larger lift increase was noted.
