摘　　要：超空泡航行体通气规律对空泡形态控制具有重要意义。本文描述了在高速水洞中建立水下航行体通气率对超空泡形态及稳定性影响的一种试验研究方法。基于不同空化器和模型攻角条件下的空泡形态及通气率测量试验结果,总结得到无量纲通气率计算的经验表达式。通过对有、无尾翼条件下的通气率试验进行比较,初步获得尾翼对超空泡泄气的影响规律。研究结果表明,通气率需要保持在一定范围内方可获得形状稳定、边界清晰的通气超空泡。依据试验结果给出了超空泡稳定性的判别方法。Ventilation law of supercaviting vehicles plays an important part in cavity shape control.This pa⁃per presents the development of an experimental method in high speed water tunnel to study the supercavity stability which describes the relationship between cavity shape and ventilation rate.An empirical formula was established based on test results of cavity shape and ventilation flow rate under different cavitator sizes and angles of attack of the model.By making analysis and comparison of the experiment results with and without tail wings,the influence of tail wing on ventilation law was preliminarily obtained.The results show that ventilation rate needs to be kept in certain range in order to maintain a steady and smooth ventilated su⁃percavity.
