Abstract / Description of output

The aerodynamics of a Sparkman and Stephens 24-foot sailing yacht was investigated Full-scale pressure measurements were performed on the mainsail and the genoa in upwind condition Pressure taps were adopted to measure the pressures on three horizontal sections on the windward and leeward sides of the two sails Several trims and apparent wind angles were tested The present paper shows the pressure distributions on the sails and correlates the measured pressures with the flow pattern In particular leading-edge laminar separation bubble turbulent reattachment and turbulent separation are discussed Pressure measurements are also adopted to draw some trim guidelines (C) 2010 Elsevier Ltd All rights reserved
