Abstract: Abstract: In order to get a full understanding of the conical cavitator, an experiment of certain cavitator was conducted in a water tunnel, and a numerical simulation of conical cavitator with different cone angles was conducted. The results of the experiment and numerical simulation were analyzed, and the characteristics of the drag and lift were obtained. The results show that the cone angle have a great influence on force characteristics of the conical cavitator. The hydrodynamic changes with certain regulation when the cone angle expands. The angle of attack has an impact on the drag and lift of the cavitator. Different cone angles have different influences at the same angle of attack. The research results are meaningful for the practical use of the conical cavitator and control method of supercavitating vehicles with a conical cavitator.
