摘要： 摘要：为了分析锥形空化器的力学和流体动力学特性，对特定空化器进行水洞实验，针对各种锥角的空化器的流体动力特性进行仿真分析，并将实验与数值仿真计算的结果进行对比.结果表明：锥形空化器的锥角对其力学特性影响很大，并具有特定的变化规律；空化器的攻角对空化器的升力和阻力均有一定的影响，且不同锥角的空化器所受的力随攻角变化的规律不同.

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.

Key words: Key words： conical cavitator, hydrodynamic, cone angle, angle of attack, supercavitation
