摘要：
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. © 2024 China Ship Scientific Research Center.
