Abstract
This paper presents an experimental study on the artificial ventilation of conventional hydrofoil (NACA66 2 -215) sections. The investigation includes a study of the effect of different ventilation pressures, speeds of operation, angles of attack, ventilation locations and ventilation outlet configurations on the hydrodynamic performance of the foil. The experiments have been carried out at the High Speed Towing Tank facility of the Naval Science and Technological Laboratory at Visakhapatnam in India. A 6-component foil dynamometer has been developed for conducting the tests. A set of foils has been designed and manufactured with different ventilation locations and ventilation configurations.
