摘要：
In order to explore the hydrodynamic characteristics of conical cavitator, the experimental study of conical cavitators with different cone angles in water tunnel is conducted to obtain their hydrodynamic parameters. The influence of cone angle on hydrodynamic characteristics is analyzed. The hydrodynamic characteristics of conical cavitator with flat head and the drags under different flat head areas are also studied. The results show that the cone angle has effect on drag and lift coefficients; the position derivatives of lift coefficient are distinct at different cone angles; and the drag coefficient dose not change obviously. The cavitator can be approximated as a full conical cavitator when the flat head area is small. The experimental results provide a reference for practical use of conical cavitator and analysis of control characteristics of supercavity vehicle.
