The invention provides a design method of a conical cavitation device. The design method is characterized in that the diameter D of a vehicle is known, and the cone vertex angle alpha Z, the cone bottom surface diameter DZ, the cone height HZ, the cylinder height HY and the cylinder section diameter DY of the conical cavitation device are obtained according to formulas. The method has the advantages that the precise design method of the different structural parameters of the conical cavitation device is provided, the problems that the underwater resistance of the underwater vehicle is large and the moving speed of the underwater vehicle is low are solved, and economic loss caused by partial cavitation on the surface of the vehicle is avoided. 本发明提供了种圆锥形空化器的设计方法，已知的航行器直径D，根据公式求解出圆锥形空化器圆锥体顶角α、圆锥体底面直径D、圆锥体高度H、圆柱体高度H、圆柱体截面直径D。本发明给出了圆锥形空化器的不同结构参数的精确设计方法，还有效解决了水下航行体在水中阻力大、航速较低的问题，并且避免了航行体表面局部空化带来的经济损失。
